In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.
This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.
In this chemistry activity (page 1 of PDF SciGirls Activity: Milk Carton Boat), learners will create a blob of stretchable funny putty out of a water, borax, and glue mixture.
In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.
In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
In this activity, learners investigate the effect of heat on a reaction.
In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.
This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).
In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.
Heat makes some materials expand, and it makes others shrink.
In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the
This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.
Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.
In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.
Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.
This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.
