Illuminations on Rates of Reactions
Source Institutions
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.
Polymers are Chains (K-2)
Source Institutions
In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.
Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
Cool Hot Rod
Source Institutions
If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.
Get the Porridge Just Right
Source Institutions
Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.
Big Wave
Source Institutions
This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
What Smart Metal!
Source Institutions
In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Two Lenses in One
Source Institutions
In this activity about light, learners explore how water can refract light and change the way they see things.
Thumbs Away!
Source Institutions
Learners discover how important their thumbs are by attempting various tasks without them. After tying up their thumbs, learners attempt to legibly write their names or play catch with a tennis ball.
Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.
Density Stacker
Source Institutions
In this physics activity (page 8 of the PDF), learners will explore the property of density.
Checking For Starch
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.
Are you a Square or a Rectangle?
Source Institutions
In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.
Clothespin Workout
Source Institutions
This is a great activity about human energy production. Learners will work out with a clothespin to investigate why hockey players jump on a stationary bike after an intense game.
Water Filter
Source Institutions
In this engineering activity, challenge learners to invent a water filter that cleans dirty water.
Colors, Colors?
Source Institutions
In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th
Oily Ice
Source Institutions
In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.
DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
Light Combinations
Source Institutions
In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.
