As an introduction to the hypothesis and testing method of investigation, young history detectives engage in a special investigation of a family artifact. After watching a short video that demonstrates the method, they develop a...

Students identify the characteristics and composition of emulsions. In this chemistry lesson, students classify household products according to emulsion type. They explain how to make the best emulsion.

Students analyze a designated galaxy with a partner or in a small group.

Students complete a variety of activities related to the physical characteristics of minerals. They classify and group candy, classify rocks and complete a Pet River Rock worksheet. Students try to guess which rock goes with each...

Tenth graders explore the structure and content of galaxies. Through discussion, lab, and hands-on activities, they discover the general structure of the three types of galaxies as well as the effect they have on the structure and...

Young scholars research and they role-play the behavior of plants and animals in a salt marsh habitat as the tides change.

Students explore how to draw contour lines from limited data and extend this knowledge to real data sets. They participate in many opportunities from students to assess their own progress and the exercise is completely online.

Students study coral reefs and the controversy over coral bleaching. They role-play a debate over the issue and come up with a compromise to protect the reefs and the economies that depend on them.

Students examine termites and their trail-marking behaviors. They draw lines on paper with various ink pens and experiment to see which types of ink the termites follow--or which inks do and do not elicit trail marking behavior.

Students construct a viable insect collecting apparatus. Students determine the effectiveness of the instrument he has designed by collecting specimens.
