Masses & Springs
Source Institutions
In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

Wheat Evolution: Dough Washing
Source Institutions
In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

Wheat Evolution: Dough Rising and Baking
Source Institutions
In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

In this activity, learners explore materials through paper chromatography.

Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

Mystery Sand

It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

The Gas You Pass

Although we may not admit it, all humans fart or pass some gas. In this activity, learners make their own model to mimic food passing through intestines and discover what releases gas.

Invisible Sunblock
Source Institutions
This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

A Crayon Rock Cycle- Metamorphic
Source Institutions
This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

Exploring Size: Powers of Ten
Source Institutions
In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.
