Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Though an alternative method is suggested, the best way to carry out this investigation is with the use of a computer-interfaced motion detector. Physics fanatics hang a mass on the end of a spring and analyze its motion verbally,...

During an inquiry-based lesson, scholars decide which variable to test and then design an experiment to determine the needs of producers. After two weeks, they complete a full analysis and research paper.

Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine...

Objects are larger (or smaller) than they appear! Scholars use a laboratory investigation to explore the difference between resolution and magnification. The activity allows them to calculate the size of the field of view of their light...

In May of 1981, the Winter Park Sinkhole in Florida first appeared and is now referred to as Lake Rose. Scholars learn about the causes of sinkholes through an inquiry project. Then, they analyze recent data and draw conclusions to...

What exactly is a dirt baby, you might ask. Look over the plan to find out! All of the materials and procedures necessary for creating a dirt baby, such as grass seeds, dirt, and nylon stockings, are listed, along with ideas for...
