BEETLES: The Coming Out

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

Apply scientific principles to designing an experiment to study organisms living on the coral reef in our oceans. Through reading, individuals learn about the coral reef ecosystem and important factors that affect its function....

This lesson certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many motion concepts:...

One of the factors that automotive engineers must consider is wind drag. The less wind drag, the more efficient the car will be. They perform many tests in wind tunnels, then refine their designs and test again. Using simple materials,...

Teams take their cavern designs and build a model from clay or paper mache that can be buried in sand. Testing involves dropping a bowling ball on the buried cavern. Teams dig out their cavern, inspect it for damage, and consider...

Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

Students evaluate the impact beetles have on plants. In groups, they select plants to expose to leaf-feeding beetles and place those beetles on the caged plants. They observe the beetles and discuss the insect and plant interaction...

While this lesson is based on the Bruchid beetle, the focus is on conducting a scientific investigation. Ecology explorers vary the temperature or the type of leaf that Bruchid eggs are laid on and test for effects on the development...

Groups design the ultimate roller coaster by considering potential and kinetic energy. They test their designs using marbles and then go on to rate each group's design based on aesthetics, loop diameter, and cost.

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...
