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.

In this follow-up to Fast Plants^® 1 - Growth and Genetics, continue to explore inheritance of traits in Wisconsin Fast Plants. Infer the genotype of a "mystery P2 parent" of a set of Fast Plants based on the traits of the P1, F1, and F2 plants. Then create designer Fast Plants by selectively breeding plants with desired traits.

Grow Wisconsin Fast Plants^® in a simulated lab environment. Explore the life cycles of these plants and how their growth is influenced by light, water, and crowding. Practice pollinating the plants using bee sticks, then observe the traits of the offspring plants. Use Punnett squares to model the inheritance of genes for stem color and leaf color for these plants.

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.

There has been an outbreak of legionnaires’ disease in a small town. This disease is caused by legionella bacteria that proliferate in contaminated water supplies. Students take on the role of a civil engineer to investigate how the water treatment plant has failed to get rid of all the contaminants in the water and design a new method.

Use genetic engineering techniques to create corn plants resistant to insect pests or tolerant of herbicides. Identify useful genes from bacteria, insert the desired gene into a corn plant, and then compare the modified plant to a control plant in a lab setting.

5 Minute Preview

Perform experiments with several seed types to see what conditions yield the highest germination (sprouting) rate. Three different types of seeds can be studied, and the temperature, water and light in the germination chamber can be controlled. No two trials will have the same result so repeated trials are recommended.

Study photosynthesis in a variety of conditions. Oxygen production is used to measure the rate of photosynthesis. Light intensity, carbon dioxide levels, temperature, and wavelength of light can all be varied. Determine which conditions are ideal for photosynthesis, and understand how limiting factors affect oxygen production.
