Physics stars design mobiles that demonstrate rotational equilibrium. They take measurements and solve related equations for force by graphing, substitution, or determinants. This is a well-developed lesson plan, complete with student...

With paper DNA patterns, budding biologists model translation and base-pair substitution within sequences. Through these activities, they examine how mutations can result in genetic disorders. The modeling that occurs is an enlightening...

In this stoichiometry worksheet, students solve several problems using the stoichiometric method. Students find the percent, theoretical, and actual yield for all problems presented.

Students participate in an interactive instructional activity using the scientific method to study biodiversity.  In this insect monitoring instructional activity, students simulate the layers of soil and the insects that would live...

Students practice the scientific method in the classroom, either in preparation or as a substitution for real-world field experience. They examine a simulated biodiversity research situation, using a "mini-plot" or sampling square...

For this rocket launch worksheet, students solve 3 problems about the Ares 1X rocket and its launch, trajectory, and motion in both the vertical and horizontal direction.

Students become aware of the environmental problems caused by acid rain and study the pH scale. They determine acidity of local rain water.

Students explore the concepts of rotational equilibrium. They examine the history Alexander Calder and his mobiles. Students solve simple algebraic equations. They predict, draw conclusions, graph equations and examine the rotational...

In this chemistry laboratory, learners will investigate the activity of 4 unknown metals and rank them according to their activity. In order to achieve this objective, students will be combining a 1M HCl solution with each metal and...
