Introduction to Soil Nitrogen and Demonstration of a Simple Test Procedure

Make your work as a teacher a little easier with a physical science project on simple machines. After introducing young scientists to these devices and identifying their different uses around the school, this project engages children in...

Students list the three types of mineral particles that form soil. They explain the importance of an optimum soil texture. They form an hypothesis and make observations. They also draw a conclusion.

The choice is simple: create a PowerPoint presentation, write a book, or invent a compound machine. Whichever project your young scientists choose, they will be engaged in creatively demonstrating their knowledge of simple machines and...

Heat things up in your physical science class with this interactive lesson series on thermodynamics. Through a series of class demonstrations and experiments, young scientists learn how heat is transferred through conduction, convention,...

As part of a study of soil and composting, fourth graders become worm farmers, build a vermiculture bin, observe, and care for their red worms.

Trying to plan a physical science unit on forces and motion? Make your work a little easier with this comprehensive collection of simple machines resources. Offering a wide variety worksheets, activities, and projects, these materials...

Seven superb slides sharpen science students' scoop on soil. In viewing them and reading the accompanying captions, your class will uncover the importance, different types, horizons, and protection of soil. They can then assess their new...

Begin a full lesson plan 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...

Expose your class to the steps of the nitrogen cycle with this short clip. Colorful computer imagery and animation explain how nitrogen travels from the atmosphere as a gas into plants and soil, where bacteria convert it into nitrates....

One of the factors that automotive engineers must consider is wind drag. The less wind drag, the more efficient the car will be. They perform many tests in wind tunnels, then refine their designs and test again. Using simple materials,...
