Bee TalkAdd to list Details
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.
Incredible Shrinking ShapesAdd to list Details
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.
Surface Tension IcebreakerAdd to list Details
This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.
Funny PuttyAdd to list Details
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.
Monster MallowsAdd to list Details
In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.
Underwater FireworksAdd to list Details
In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.
Illuminations on Rates of ReactionsAdd to list Details
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.
Heat Speeds Up ReactionsAdd to list Details
In this activity, learners investigate the effect of heat on a reaction.
Hollandaise Sauce: Emulsion at WorkAdd to list Details
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.
LEGO® Chemical Reactions
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).
Making a Battery from a PotatoAdd to list Details
In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
Molecules in MotionAdd to list Details
In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.
Shrinky DinksAdd to list Details
Heat makes some materials expand, and it makes others shrink.
Chemistry in the KitchenAdd to list Details
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
Air, It's Really ThereAdd to list Details
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.
Water: Clearly Unique!Add to list Details
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.
The Amazing Water TrickAdd to list Details
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.
Traveling Nanoparticles ModelAdd to list Details
This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.
Moving Molecules!Add to list Details
In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw
