There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

High school physical scientists collide with motion. They work in pairs to design a paper car that will protect a raw egg during a head-on collision. Measurements of distance traveled, time of run, vehicle specs, and photo gate flags are...

Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...

Young scholars complete a Webquest which investigates the chemistry in items such as shampoo. They research the Internet, perform a lab experiment, and write a scientific lab report with their findings. Upon completion of the activities,...

In this physics worksheet, learners design and build a signal generator. They write a lab report and answer 4 short answer questions about their design.

Students investigate the pulling force of CEENBoT. For this physics lesson, students suggest modifications to increase the kinetic coefficient of friction and eventually the pulling force. They write a complete lab report about the...

Students explore electricity by conducting a series of experiments. For this physics lesson, students discover the relationship between current, voltage and resistance. They calculate voltage and power in a given system.
