Students examine how salt water is more dense than fresh water through experimentation with eggs.

Students use streaming videos, web sites, and hands on activities students to explore matter. They focus on how temperature affects matter and what the particles look like in the states of matter.

Students investigate the dirt in the air. In this air quality activity, students use aluminum foil and petroleum jelly to discover if there is dirt in the air. Students discuss results.

Pupils create "catchers" that collect dirt particles from the air. They observe the particulate matter that is collected from the air and discuss the effects and causes of air pollution.

This is an educator's guide for a unit on things that sink or float. It includes lesson plans, experiments, and activities. Students apply the scientific method as they investigate whether objects sink or float.

Students sort objects according to whether they sink or float.

For this activity, young scholars make predictions about whether different objects float or sink, then test them. They are asked to record their observations and results for each, and compare their results to others'.

Students will explore matter that sinks or floats when submerged in water and that matter is categorized as either a sinker or a floater. Students will work actively in small, cooperative learning groups as well as gather in a whole...
