Excite classes with a STEM project-based learning lesson covering chemical reactions. Groups study the different types through simulations and hands-on activities. They pick one type (synthesis, decomposition, single displacement, double...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

High schoolers explore how PCR works through various activities. In this biology lesson, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

The guided inquiry activity enables students to identify the five basic types of reactions - synthesis or composition, decomposition, combustion, single replacement and double replacement. Students will also begin to predict the products...

Problem set tests understanding of Photosynthesis by providing multiple choice questions accompanied by related tutorials. Set 2 Focuses on carbohydrate synthesis.
