In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).
