Fourth graders participate in a ball identification exercise to help them identify birds. As a class, their teacher throws them a variety of different sized and colored balls for them to describe. Using these factors, they work together...

Students investigate circular motion in two different activities. In the first, students observe the path of a rolling marble on a paper plate. In the second, students play a game of catch using a tennis ball inside a plastic bag. ...

Pupils find the center, foci, vertices, and asymptotes of hyperbolas. They graph hyperbolas and determine the equation of a hyperbola with a horizontal transverse axis. They derive general coordinates for the foci of a hyperbola with a...

Students explore the reaction rates of an enzyme-mediated reaction through experimentation. In small groups, they use everyday objects to demonstrate the effects of environmental variables on enzyme function. Students graph and...

Learners examine how to conduct simple investigations and use simple equipment to gather data.  In this magnet lesson students decide what types of objects are attracted to magnets. 

Students explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.
