P 5 – 7 are studying plants and biodiversity as this term’s science topic. Today we set up an experiment with the hypothesis of:
Does fertiliser improve the growth of plants?
To keep it a fair test our little scientists determined that we needed to control the variables and the constants:
Constants:
- Type of soil
- Type of seed
- Same amount of sunlight (same location)
- Same temperature (same location)
Variables:
- Adding fertiliser to the water for the plants
Everyone planted a pea seed. Half the class have used just water and half added fertiliser to the water. We predicted what we think we might observe over time. Some think the plants will grow to the same height and some think the fertilised water plants will grow taller . We will monitor the growth over time, then apply our data handling skills to produce a graph of our results for comparison. We might even throw in a few mean, mode, median and range calculations while we’re at it!
