Which Powder is It?
Source Institutions
In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.
Hot and Cold
Source Institutions
In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.
Snowstorm in a Jar
Source Institutions
In this activity, learners will experiment with density and chemical reactions to create a flurry activity.
Diving Submarine
Source Institutions
Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.
DIY Bath Bombs
Source Institutions
In this activity, learners will explore acid-base reactions and create their own bubbly results.
Mixing and Unmixing in the Kitchen
Source Institutions
In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.
Atoms and Matter (K-2)
Source Institutions
In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.
Changing Colors
Source Institutions
In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.
Fizzy Fun
Source Institutions
In this activity, learners test what happens when they put baking power on different frozen liquids.
Finding Colors
Source Institutions
In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.
Ready, Set, Fizz!
Source Institutions
In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.
Chemical Identification
Source Institutions
In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.
Breaking Up with Combustion
Source Institutions
This activity teaches combustion as the interaction of a fuel source and oxygen.
Flubber: Make a polymer!
Source Institutions
This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.
