In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

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, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
