Plant Project

Title:
What do plants need to live and grow?

Authors:
B1 Science Class

Purpose:
To study how the availability of sunlight, water and air affect the life and growth of plants.

Hypothesis:
The plant that gets sunlight,water and air will do the best. The plant that only gets air will do the worst.

Materials:
Three plants, sunlight, water, air and a paper bag.

Procedure:
Put three plants in front of the window. Water one plant every day. Don’t water the other two plants. Put a paper bag over one of the non-watered plants. Take pictures of the plants twice a week. Observe the plants for two weeks.

Results:
The plant that got sunlight, air and water looks the best. The plant that got sunlight and air looks the worst. The plant that got sunlight, air and water has the most new buds. The plant that got only air has the least new buds. The plant that got only air has the most dead flowers. The plant that got sunlight, air and water has the least dead flowers.

Conclusions:
To grow and be healthy, plants need water, sunlight and air. If a plant does not get all these, it will look bad, have fewer new buds and have more dead flowers.

Diet Coke – Mentos Project

Title:
The Diet Coke Mentos Fountain and Type of Soda

Purpose:
We wanted to know if type of soda used will affect the size of the fountain.

Hypothesis:
We thought Cider and Diet Coke would make the same size fountain.

Materials:
One bottle of Cider, one bottle of Diet Coke, two packages of mint Mentos, and a measuring cup.

Procedure:
First,we prepared the cider. Next,we dropped the Mentos into the bottle of Cider. Then we measured the volume of the fountain. Next, we prepared the Diet Coke. Then we dropped the Mentos into the Diet Coke. Finally,we measured the volume of the fountain.

Results:
When we put mint Mentos into the bottle of Diet Coke, 180ml of soda came out. When we put mint Mentos into the bottle of Cider, 200ml of soda came out.

Conclusions:
We thought Diet Coke and Cider fountains would be the same size, but they were not. The cider fountain was bigger. Our hypothesis was not supported.
