The hypothesis is that some plants will interact well with one another and increase in their rate of growth whereas other plants may not get along well together and growth will be delayed.

You will plant different types of plants in 5 pots, measure the growth rate of the plants, and calculate the average height.

You will need 1 packet of tomato seeds, 1 packet of corn seeds, 6 onions, 5 plastic pots, enough soil to fill the 5 pots, and a ruler.

The experiment showed that tomato plants grow well with onions but not with corn. The tomato plant grew an average of 48mm by itself in pot A but was able to grow up to 65mm when planted with the onion in pot D. However the tomato planted in pot E together with the corn, was only able to grow 28mm in the 10 days.

This science project is interesting because it explores the idea of companion planting and how it can help reduce the use of chemical pesticides to protect the plants.

To further explore this project, consider repeating the experiment using different plants like radish, potato and peas. Also, consider continuing the experiment over a longer period.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
