Force and Fan Carts
Explore the laws of motion using a simple fan cart. Use the buttons to select the speed of the fan and the surface, and press Play to begin. You can drag up to three objects onto the fan cart. The speed of the cart is displayed with a speedometer and recorded in a table and a graph.
- Determine that a force is needed to cause a change in motion.
- Understand that friction is a force resisting motion.
- See that a moving object will continue at constant speed if no forces are acting upon it.
- Determine that larger forces cause greater changes in motion.
- Understand the relationship between speed, position, and time.
- Observe that a constant force gives rise to a constant change in speed.
- Utilize a bar graph and data table to interpret motion.

Cell Energy Cycle
Explore the processes of photosynthesis and respiration that occur within plant and animal cells. The cyclical nature of the two processes can be constructed visually, and the simplified photosynthesis and respiration formulae can be balanced.Learn Moreabout Cell Energy Cycle
Observe the steps of pollination and fertilization in flowering plants. Help with many parts of the process by dragging pollen grains to the stigma, dragging sperm to the ovules, and removing petals as the fruit begins to grow. Quiz yourself when you are done by dragging vocabulary words to the correct plant structure.Learn Moreabout Flower Pollination
Investigate the growth of three common garden plants: tomatoes, beans, and turnips. You can change the amount of light each plant gets, the amount of water added each day, and the type of soil the seed is planted in. Observe the effect of each variable on plant height, plant mass, leaf color and leaf size. Determine what conditions produce the tallest and healthiest plants. Height and mass data are displayed on tables and graphs.Learn Moreabout Growing Plants
Plants and Snails
Study the production and use of gases by plants and animals. Measure the oxygen and carbon dioxide levels in a test tube containing snails and elodea (a type of plant) in both light and dark conditions. Learn about the interdependence of plants and animals.Learn Moreabout Plants and Snails
