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...

Eighth graders watch a Lab Safety video and discuss particular questions related to lab safety. Lab equipment is then distributed and the students inspect the equipment and record their finding in their journal. Finally, in groups, 8th...

Protect skin from UV radiation! Groups design and conduct an experiment to test the effectiveness of UV safety products. The groups collect the data from the experiment and prepare a lab report. In the second day of the activity,...

Pairs use an online simulation to determine the epicenter and magnitude of an earthquake. Using real data about the earthquake's maximum S wave amplitudes, they then determine the magnitude. The resource provides a great career...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

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...

Find out if your class agrees with Ice Age: Continental Drift ... or if it's just a fun family movie! Class members research the theory of continental drift, examine evidence of plate tectonics, connect...

An outstanding instructional activity awaits your physics fledglings! After reading about how hydrogen can act as an energy carrier, they examine the electrolysis of water using solar power. They test the gases produced for flammability...

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

Make the strongest beam possible using taffy? Groups mold a taffy-water mixture into a beam and a reinforcing material of their choice. To finish the final installment of a two-part series, participants test its strength by adding...

Students create a bird feeder to form their technological skills and create a better bond with nature. In this nature lesson plan, students use websites, technology, brainstorm ideas, and build models.

Make Newton proud. Scholars apply their understanding of forces and energy to an engineering design challenge. They learn about simple machines, create a presentation on Newton's laws, and develop a balloon-powered car.
