In your class, grow a number of plants or flowers from seed. Read the packet to find out how much light and water the plant needs to grow. Take one group of the plants and follow these directions fully. Take another group of the plants and give them half the amount of water recommended on the packet.
What sort of differences would you expect to see between the two groups as they grow?
Each week as the plants grow, observe and make notes about their appearance. Measure their height and describe their appearance.
Note the differences (if any) between the two groups of plants. What is the average difference in their height? What are the differences in their appearance? What conclusions can you draw from this about plants and water?
