All agricultural science experiments.

All of the experiments on the new Ag Science course including hypothesis and predictions.

1. Determine the soil texture of a soil sample by hand testing

Hypothesis: We can figure out soil textures using hand testing.

Prediction: If we use hand testing then we can figure out soil textures.

  • Take a dry sample and rub it between finger and thumb. Take note of grittiness/ smoothness.
  • Wet soil sample with water and rub between fingers and thumb, noting grittiness/ smoothness. Note plasticity (ability to be moulded). Note if sample is sticky or not.
  • Roll sample into ball. Record if it is possible.
  • Roll sample into threads on a flat surface. Record if this is possible
  • Attempt to make a ring out of threads. Record if this is possible.

Result: Soils with high sand content didn’t form threads/ be moulded. High clay content soils are sticky and mouldable- able to form a ball, thread and ring.

2. Determine soil texture of a soil sample by sedimentation

Hypothesis: We can figure out soil textures through the process of sedimentation.

Prediction: If we use the process of sedimentation then we can figure out soil texture.

  • Add soil sample to beaker of water and stir it with stirring rod to break up any large lumps of soil.
  • Pour mixture into graduated cylinder, rinsing all soil from the beaker into the cylinder. Ensure all soil is covered.
  • Place stopper on cylinder and shake to mix soil and water thoroughly.
  • Leave to settle for a few hours overnight.
  • Observe layers that have settled in the graduated cylinder. Sand settles at the bottom, silt above sand, and clay above silt.
  • Using graduation marks on cylinder, record the amount of sand, silt and clay in the soil sample as a % of the total amount of soil.
  • Use soil triangle to classify soil sample.

Results: We can see defined layers in the soil sample and are able to calculate % of sand, silt and clay.

3. Determine soil texture of a soil sample using a soil sieve

Hypothesis: We can figure out soil textures using a soil sieve.

Prediction: If we use a soil sieve then we can figure out soil texture.

  • Place a soil sample in an over to dry out completely.
  • When dry, crush with a pestle and mortar.
  • Weigh in weighing boat (making sure to subtract the weight of the boat itself to subtract from mass to find mass of soil alone).
  • Place crushed sample in largest soil sieve. Place cover on top and shake.
  • Remove cover from each sieve and separate out each sieve.
  • Pour contents of each sieve into separate boats (ensure you know the weight of the individual boat to subtract).
  • Weigh each sample in turn.
  • Calculate mass of sand, silt and clay as a % of total soil mass.
  • Use a soil triangle to classify your sample.

Results: Sand, the largest particles, is caught in the largest sieve, then silt particles in the medium sieve, then clay in the smallest sieve.

4. Determine and compare the total pore space in compacted vs uncompacted soil samples

Hypothesis: The total pore space will be higher in the uncompacted soil than the compacted soil.

Prediction: If I compact a soil sample then its pore space will be lower than uncompacted soil.

  • Add an amount of dry uncompacted soil to a graduated cylinder.
  • Tap the cylinder to remove any large air pockets.
  • Take an equal amount of compacted soil and add to second graduated cylinder.
  • Add an equal amount of water as soil to each graduated cylinder.
  • Allow cylinders to stand for one hour. 
  • Calculate volume of water occupying pore space, hence calculating % pore space in compacted and uncompacted soils.

Results: Uncompacted soil has a higher volume of water in its pores compared to compacted soil.

5. Compare capillarity in a compacted soil and an uncompacted soil

Hypothesis: Compacted soils show high capillarity then uncompacted soils.

Prediction: If soil is compacted then the rate of capillarity will be higher.

  • Use cotton wool to plug ends of two open ended tubes.
  • Fill first tube with an amount of uncompacted soil.
  • Fill second with an equal amount of compacted soil.
  • Broadcast equal amounts of cress seeds on top of each soil sample.
  • Stand both in a water trough filled with water.
  • Leave in trough for a few hours.
  • Record which tube’s cress seeds germinate first (indicating they received water)

Results: The compacted soil, where pore space is smaller shows greater capillary action and has its seeds germinate. The uncompacted soil’s seeds did not. 

Note: If soil becomes too compacted capillary action will also be limited.

6. Compare the infiltration rate of a compacted soil and an uncompacted soil

Hypothesis: Uncompacted soil will have a higher infiltration rate than compacted soil.

Prediction: If soil is uncompacted, then it will have a higher infiltration rate compared to compacted soil.

  • Line a funnel with filter paper and fill with dry compacted soil.
  • Line a second funnel with an equal amount of uncompacted soil.
  • Clamp both funnels in retort stands and place a beaker beneath each funnel.
  • Using a graduated cylinder, measure an amount of water and pour it into both beakers at the same time.
  • Using a timer, record how long it takes the first drop of water to drip from the bottom of each tube and compare which was faster.

Result: The uncompacted soil drained faster then he compacted soil meaning its infiltration rate was higher. This is due to the large pore spaces in uncompacted soil.

7. Show flocculation in a soil sample

Hypothesis: Hydrochloric acid will promote flocculation better than calcium chloride, aluminium chloride and sodium chloride.

Prediction: If hydrochloric acid is used then it will be more effective than calcium chloride, aluminium chloride and sodium chloride at promoting flocculation.

  • Add 1g of clay to deionised water and mix thoroughly.
  • Pour 10cm3 of the clay water suspension into each of four test tubes.
  • Add 1cm3 of hydrochloric acid to the first test tube.
  • Add 1cm3 of calcium chloride to the second test tube.
  • Add 1cm3 of aluminium chloride to the third test tube.
  • Add 1cm3 of sodium chloride to the fourth test tube.
  • Stopper each tube and shake to mix.
  • Observe and record levels of flocculation at 5 min intervals.

Results: Hydrochloric acid was the most effective flocculant followed by calcium chloride, then aluminium chloride. Sodium chloride was the least effective flocculant.

8. Show cation exchange in a soil sample (HL only)

Hypothesis: Cation exchange occurs when potassium chloride is added to soil sample.

Prediction: If potassium chloride is added to a soil sample then cation exchange will occur.

  • Add 5g of dry, sieved soil to a filter funnel.
  • Use a dropper to add potassium chloride solution to the soil, drop by drop.
  • Collect water that filters from the soil (leachate) in a clean, dry beaker.
  • Test the leachate for calcium by adding 10 drops of ammonium oxalate to leachate. If white precipitate forms, calcium is present.
  • Discard leachate and repeat steps 1-4.
  • Repeat until leachate does not test positive for calcium.

Results: When potassium chloride was added to clay soil solution, cation exchange occurred as white precipitate did not form after a sufficient amount was added.

9. Determine % of soil organic matter and soil organic carbon in a soil sample

  • Weigh an empty crucible and record its mass.
  • Add dry soil sample to crucible and record mass. Subtract mass of crucible.
  • Put crucible on a pipe clay triangle on tripod stand.
  • Heat soil with Bunsen Burner. Humus should glow red as it burns and produces smoke.
  • Heat until humus is burnt off, doesn’t glow and there is no more smoke.
  • Remove crucible from tripod with tongs and reweigh.
  • Take final mass from initial mass and out over initial mass
  • % Organic Matter = Mass of organic matterMass of original soil sample multiplied by 100/1
  • Calculate % soil organic carbon.
  • % SOC = % SOM 0.58

10. Isolate and grow bacteria from clover root nodules

Hypothesis: Bacteria will grow on agar if Rhizobium bacteria is present.

Prediction: If Rhizobium bacteria is present, then bacteria will grow on agar.

  • Wash roots of a clover plant under running water.
  • Use a scalpel to remove a portion of root with a large pink nodule.
  • Sterilise surface of nodule and root with disinfectant, then wash with alcohol.
  • Rinse off root nodule with water.
  • Crush root nodule with sterile glass rod in sterile petri dish.
  • Sterilise inoculating loop in Bunsen Burner flame until it glows red. Allow hoop to cool for 20secs.
  • Transfer some of the contents of the crushed root nodule onto a nutrient agar plate.
  • Seal and incubate upside down at 25ºC for one week.

Result: Colonies of bacteria are present on agar.

11. Show earthworm activity in a soil sample.

Hypothesis: Worms will blend together soil layers.

Prediction: If worms are active in soil, then soil layers will be mixed.

  • Fill wormery with distinct layers of soil, sand, clay and chalk. Alternate layers.
  • Add some organic matter (e.g. leaf litter) to top layer.
  • Add earthworms to wormery.
  • Add water to moisten soil.
  • Cover with black bag to block out light.
  • Leave in a cool place for at least a week, keeping soil moist.
  • Record changes after a week.

Results: Wormery soils layers will have blended together as worms burrowed through the soil.

12. Estimate number of earthworms in a pasture.

  • Measure area of pasture.
  • Place quadrat on a pasture.
  • Remove all vegetation within quadrat with scissors.
  • Make warm water and washing up liquid solution.
  • Pour solution over area within quadrat.
  • Wait for worms to come to the surface.
  • Count each worm that surfaces and put them into container so as to not count them twice.
  • Do not count worms that surface outside of quadrat.
  • Record number of earthworms collected and return them to soil.
  • Repeat in other locations.
  • Find average.

Result: Calculate area of pasture. Divide area of pasture by area of quadrat to find how many quadrats could fit in the field. Multiply number of quadrats by average number of worms per quadrat to find approximate earthworm population of field.

13. Investigate the complexity associated with the genetic inheritance of traits by hybridising two varieties to determine the rate of transfer of the required trait to the next progeny.

Hypothesis: Using subsequent generations we can determine what traits in a plant are dominant.

Prediction: If we hybridise two plants then we can determine which traits are dominant through their expression in subsequent generations.

  • Obtain two plants of the same species which express a unique trait (e.g. petal colour).
  • Supply plants with, water, fertiliser and light.
  • When flowered, rub a cotton bud of the anther of one plant and transfer pollen onto the stigma of the other plant.
  • When seed pod has swelled and petals have died off, remove seed pod from plant.
  • Store seeds until conditions are suitable for sowing.
  • Plant seeds in new tray, water them and ensure nutrient levels are sufficient.
  • Upon germination, transfer seedlings into individual pots.
  • Once petals have flowered, record how many of each petal colour is present.
  • Calculate ratio of each trait to determine rate of transfer.

Results: Majority of the plants will display the dominant colour however a small majority may display the recessive colour depending on the genome of the parent plant. Further accuracy can be obtained through subsequent breeding.

14. Compare plant uniformity from certified and uncertified seeds. (HL only)

Hypothesis: Certified seeds will have increased uniformity.

Prediction: If we use certified seeds, uniformity will increase.

  • Obtain equal amounts of certified and uncertified seeds.
  • Identify characteristics of certified seed that will classify it as uniform (e.g height, colour)
  • If a cereal grain, let soak in a labelled beaker for 24hrs.
  • Plant sample in separate trays.
  • Provide both with equal amounts of light, water and nutrients.
  • Monitor seeds until both have become established.
  • Count the number of certified and uncertified seeds which are uniform.

Results: Certified seeds will have higher rates of uniformity.

15. Investigate the effect of the weather and soil conditions on the % germination of an agricultural seed.

Hypothesis: Adverse weather and soil conditions have a negative effect on the % germination of a seed.

Prediction: If exposed to adverse weather and soil conditions, then % germination will decrease.

  • Place equal amounts of seeds in three trays of soil.
  • In tray A, limit water given to seeds.
  • In tray B, compact the soil.
  • Tray C will act as a control, let all conditions be ideal.
  • Expose all trays to equal light, temp, oxygen concentration.
  • Calculate % germination of seeds.

Results: Seeds in tray A and B had a low % germination due to adverse weather and soil conditions. Tray C had a high % germination.

16. Investigate the effect of nutrients on the growth of a sample of plants and measure the biomass of these plants above and below the ground.

Hypothesis: Seeds with full access to nutrients will have higher biomasses above and below ground.

Prediction: If seeds have access to all nutrients needed for growth then they will have high biomasses above and below ground.

  • Set up 4 trays with equal numbers of seedlings.
  • Place each seed tray into a separate water trough with an oxygen supply.
  • Add a different mineral solution (Sach’s solution) to each trough. 
  • Tray A, a solution with all minerals.
  • Tray B, a solution with all but nitrogen.
  • Tray C, a solution of all but phosphorus.
  • Tray D, a solution with all but potassium.
  • Leave to grow for one month.

  • Harvest seedlings by cutting them where the stem emerges from the soil.
  • Place all in a bag and weigh. Repeat for each tray.
  • Collect all roots.
  • Clean off soil.
  • Weigh all and repeat for each tray.

Results: Seeds with access to all nutrients will have a higher biomass both above and below ground.

17. Investigate the dry matter content of a crop.

Hypothesis: Rooster variety of potato will have higher DM than Cara variety.

  • Choose potato varieties, wash away any soil and dry.
  • Weigh each potato variety separately.
  • Weigh empty beaker (to subtract from final)
  • Cut potatoes into equal sized pieces and add to beakers.
  • Place in oven at 100ºC and reweigh after 15 mins.
  • Continue to heat until mass is constant.
  • Repeat for each variety.
  • Calculate dry matter by subtracting beaker weight from beaker and potatoes.
  • Calculate % dry matter.
  • Final mass of potatoes divided by Initial mass of potatoes multiplied by 100/1

Results: Rooster varieties had higher DM content then Cara.

18. Investigate the botanical composition of an old permanent pasture.

Hypothesis: A permanent pasture will have high levels of biodiversity.

Prediction: If a grassland is a permanent pasture then it will have high levels of biodiversity.

  • Throw a pen over your shoulder and place the quadrat on top.
  • Record plants within the quadrat.
  • Repeat 10 times in various random areas.
  • Calculate % frequency of each plant found.

Results: Permanent pastures have high levels of biodiversity.

19. Investigate DM content of grass

  • Use scissors to cut grass into short, equal lengths.
  • Weigh beakers (to subtract later)
  • Add equal amounts of grass to three beakers.
  • Weigh each.
  • Place in an oven at 100ºC.
  • Remove and weigh every 10 mins until constant mass achieved.
  • Record results and calculate DM content.
  • Final mass divided by Initial mass multiplied by 100/1

20. Compare the establishment of grass with that of one other crop (HL only)

Hypothesis: Grass will have a higher rate of establishment to clover.

Prediction: If grass is present, then it will have a higher rate of establishment to clover.

  • Count grass plants within quadrat and record in table.
  • Calculate number of plants per m2.
  • Repeat for 20 different locations.
  • Calculate average rate of establishment per m2.
  • Repeat for another crop e.g clover.
  • Compare results.

Results: Grass had a higher rate of establishment to clover.

21. Investigate quality of a milk sample over time

Hypothesis: Milk quality will decrease over time when left out in the open.

Prediction: If milk is left out in the open, then its quality will decrease over time.

Materials: 4 sterile beakers, a sample of fresh pasteurised milk, milk that was left out for 12 hrs, milk that was left out for 24hrs and milk that was left out for 48 hrs. Resazurin dye.

  • Label 4 beakers A, B, C, D.
  • Add equal volumes of fresh pasteurised milk, milk that was left out for 12 hrs, milk that was left out for 24hrs and milk that was left out for 48 hrs, one to each beaker.
  • Add 1cm3 (one centimetre cubed) of resazurin to each.
  • Record results.

Results: If resazurin turns white, high levels of bacteria are present- bad quality, light pink- poor quality, deep pink- fair quality, blue/ deep mauve- good quality, blue (no colour change) – excellent quality.

SPA - Specified Practical Activity

Over the two years of the course, each learner is required to complete and prepare reports on the specified practical activities which are included as learning outcomes in the specification. The reports will not be externally assessed, but must be available for inspection and retained until the end of the assessment process.

There is no particular method prescribed for these activities, which may be planned and carried out in small groups but must be reported on individually. These reports can be completed using any suitable media. The skills and understanding developed in these activities will prepare students for the individual investigative study. The following videos have been highly recommended to Scoilnet by teachers and focus on the specified practical activities. These videos were created by Leaving Certificate Agricultural Science teachers in Ireland.

Welcome back, Ag Science.

So, my Ag Science class finally reconvened last night, and since Ag Science is an epic subject I was suitably delighted. Reasons for its epicness are twofold, one being that I’m an out and proud bogger. My nickname is Kitty, that should give you fair indication. Yeah, I know I live in Cork, and sadly I don’t see fields when I look out my window. Just boy racers mostly. But one of my best friends lives out the backarse of Laois, and for the past 5 years she’s been schooling me in the ancient and noble art of culchiness. She’s been my sensei, showing me how to do the perfect ‘culchie nod’ and the importance of a good cuppa tae.Her Dad is our equivalent of Buddha, the example for all good culchies to aspire to. He achieved Bogger Nirvana a few months back when he procured a shiny new Massey Ferguson. Ironically enough, we had to explain what the term culchie actually meant to him, but anyway. Ag Science as a subject is basically a dream come true for me. I mean, talking in detail about cow husbandry, could it get any better? Actually yeah, it could, we get to draw graphs about cows too…jackpot!

The other reason is that Ag Science is a fairly feckin easy ride, no offence to any  farmers that might be reading this. Not trying to insinuate you have an easy job, but the theory of it is pretty straightforward. After two hours of study, I could pretty much sing off the notes. All this being said, I might have to come back here in June and eat my words with a side of cabbage, because the exam’s gotten way harder this year. The SEC, in their infinite wisdom, decided to throw in questions that weren’t on the course, just for the craic. Didn’t want anyone being bored in the exam, bless them.  The standard for he project’s gone way up too, they’re expecting a short novel at this stage pretty much. My teacher thinks they want rid of Ag Science because it’s way too easy to be considered a legitimate science subject, and it’s making a mockery of the Leaving Cert. Frankly, I think that’s insulting farmers, but anyway. Point is, they’re making it nigh on impossible to get an A.  And between my class of total wasters, and a teacher who insists on spending half the class telling us how wonderful he is( if you really are the best in Ireland, think you could see your way to teaching us something?)  my chances are probably halved again. Ah well. If push comes to shove, I can always write a ten page essay debating the merits of Barry’s Tea over Lyons. Sure this is it.

Just on a more positive note, remember that History project that had me up the walls a couple of weeks ago? Disney, World War II and whatnot?  Well, it’s done.  I went medieval on its ass, no pun intended. It did mean that I spent a Saturday locked in my room with just my laptop, Red Bull and We are Scientists for company (great band by the way ). But by God was it worth it. I was about ready to burst into spontaneous song once I’d finished.Course, I haven’t gotten it back from my teacher yet, I could have a million and one things to change when I do. I’m just hoping that the History gods will be smiling down on me and it’ll already be perfect. Because if I already had 20% of the exam basically sorted, that’d be class.

Hmmm, any more news? Oh yeah, to celebrate Cork winning we get a half day on Friday. First time in my life saying this ever but.. Gwan Cork! 😀

Later lads!

1 thought on “Welcome back, Ag Science.”

Limerick for life! =P My congratulations at learning the mystical trades of the culchie,but townie’s rule. 😀 Gaelic football off! Oh,and its probably unpatriotic of me,but tea is brown water. Coffee… Thats where its at. 🙂
