In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

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

Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

Learners carefully look at four known household crystals.

In this activity, learners discover how gelatin can be used as a medium for drug delivery. Learners create colored gelatin and then cut out pieces of the gelatin to simulate medicine (pills).

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this chemistry activity (page 1 of the PDF), learners will observe a physical change.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

Make your own mummy! Using a combination of salts, transform an apple into a mummy and discover how the Ancient Egyptians used drying as one step in the mummification process.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.
