Smelling in the Rain: Designing Solutions to Improve Air Quality
A respiratory physiologist is concerned about the number of asthma attacks in children within her community. On certain days, the number is higher than the respiratory physiologist might expect. She thinks something in the environment is causing more rescue inhaler use on those days. As an air quality engineer, students will work collaboratively with a respiratory physiologist to learn how some air pollutants are released directly from sources while others are formed through chemical reactions. Students will develop a system model to test design solutions to recommend a plan to help decrease air pollution in a community with a record number of asthma cases in children.

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.

Flower Pollination
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.

Growing Plants
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.
