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

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

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 activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

Get all wrapped up in a lesson about skin!

In this activity, learners discover that our hands are not reliable thermometers.

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 make different shapes that hold exactly one mole of gas (air).

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

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