Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of...

Who knew plants could be so competitive? Join your class as they observe plants competing for space and nutrients. Middle and high schoolers describe possible effects of introducing a new species into an already established...

In this living things worksheet, students will brainstorm and fill in a graphic organizer focusing on the main idea of how living things compete. Then students will add four details to support their main idea.

Middle school scientists construct a working water wheel from an aluminum pie pan. Because of the sharp edges on the cut aluminum, this activity is for mature learners only. You could have your class compete to see whose wheel can lift...

A Gallery Walk is a technique that allows small groups to visit different stations, where they examine and discuss materials about an overarching topic. Questions about rivers and fluvial processes are available in this resource;...

Students design and construct a paper rocket that can be launched with a drinking straw. They participate in a lecture and read an article about rocketry and how Newton's Third Law applies to rocket launches. Each student constructs...

Students are introduced to invasive species and how they affect the ecosystems they now occur in. They explore the basic life histories of several invasive species that are of regional and or national importance. Pupils investigate how...

Students discuss the difference between designed and natural elements. After reading an article, they discover information about current controversies in evolutionary science. In groups, they research and write dialogues between two...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

Students develop competencies in responsible and collaborative learning. Computer software and manipulatives may be used at this station to aid in independent learning.

Can my windmill pick up a weight? Given the same set of materials, groups design and build the most efficient windmill. On the first day, groups concentrate on getting a windmill to spin, while on the second day, they modify their...
