Gravity Experiment
Topsy Turvy Plants
In this gravity experiment you will study how plants grow. This plant experiment test how well a tomato plant grows when placed in a planter upside down. Under normal conditions a tomato plant is placed in the ground with the top sticking out above ground level. The roots grow downward as the top of the plant grows upward.
This science experiment turns everything upside down. The plant is expected to grow out of the bottom of the container and the roots are to grow upward toward the top. If you are interested in doing a science project on this subject you need to grow a second tomato plant in a container. You can then compare the growth rates of the two plants.
Materials
- Topsy Turvy Planter
- Potting soil
- Large flower container
- Two tomato plants
- Measuring cup
- Liquid fertilizer
Directions
- Measure the size of your two tomato plants.
- Record the information on a piece of paper with all pertinent information.
- Fill the Topsy Turvy Planter with potting soil.
- Plant one of the tomato plants in the bottom of the planter.
- Water the tomato.
- Hang it outside where it can get plenty of sunlight.
- Use the exact same amount of potting soil for your second container and plant your other tomato plant in it.
- Set the tomato plant in a container near the Topsy Turvy Planter where it can also get plenty of sunshine.
- Water the plant.
- Each week take a picture of your two tomato plants.
- Record the growth of each plant on your paper that you are recording your experiment on.
- As the tomatoes growth on both plants decide on a size that you will pick.
- At the appropriate time for each tomato take it off the vine and weigh it.
- Record each time you pick a tomato and from which plant it grew.
- Continue this until the end of the summer when the plants die or are killed by frost.
- Examine your data and decide which planter produced the most tomatoes and by how much.
