Living Things - Testing growing conditions for seeds

Post date: Sep 29, 2020 11:6:45 AM

Ms Dermody's 3rd class learned all about what conditions were needed for plants to grow. Using a number of test samples, each group planted seeds and removed one of the conditions needed for plant growth. They used a control sample which was exposed to light, heat and water and they used this to compare to samples that had

• • heat + water but no light

  • heat + light but no water 

  • light + water but no heat

After a few weeks it was clear that each of the elements are needed as there was a huge difference between the test sample and each of the other sample. It was also clear that the seeds without water made the least progress.
