In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

In this activity you'll see how the sun's tilt on its axis changes the length of shadows. For example, why is your shadow longer in winter than in summer?

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

Learners construct and launch paper helicopters.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners investigate how geometry plays a role in perspective.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.
