Integrated Unit on Nevada Solid Waste Disposal

Sugar crystal growth is observed as an example of physical change and cabbage juice pH indicator is used to demonstrate chemical change. The crystal growth is tracked over five days. The cabbage juice experiment is involved and can also...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

If you discover an unknown powder, how do you determine if it is safe? Lesson uses four different tests to identify the properties of various powders that appear the same. Then scholars get an unknown powder and have to determine which...

An average home produces twice as many emissions as an average car. Teach your class how to reduce energy consumption by replacing standard incandescent light bulbs with compact fluorescent light bulbs. Perform an experiment to compare...

Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

Students demonstrate effects of waste on environment and ways of reducing it, observe how much packaging goes into bag lunches each day, and survey their families to assess awareness levels and household recycling practices. Lessons all...

Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

Is the ice cooling down the water or is the water melting the ice? Here is a simulation that explores thermal energy transfer with iron, brick, and water. It demonstrates the flow of energy and what happens when each material is either...

Begin a full activity on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers...

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...
