In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea
Recrystallization TestAdd to list Details
In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.
Density: Make a golf ball float!Add to list Details
In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.
Separation AnxietyAdd to list Details
In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.
Formation of a PrecipitateAdd to list Details
Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.
In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved
Exploring How Liquids Behave
Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.
Conductivity MeterAdd to list Details
In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.
Water Wire: Electricity Flowing Through WaterAdd to list Details
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Beam Me Up!Add to list Details
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.
Having a Gas with ColaAdd to list Details
In this activity, learners measure the amount of carbon dioxide in a carbonated drink.
Rate of Solution Demonstration
In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.
Chemistry in the Kitchen
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
Glow UpAdd to list Details
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
Mixtures and Solutions
This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce
Sniffing for a BillionthAdd to list Details
This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.
LimewaterAdd to list Details
This is a chemistry lab activity about solutions (page 6 of the PDF). Students make a limewater testing solution for carbon dioxide and explore the concepts of solubility and precipitates.
Chemical BreathAdd to list Details
This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.
See the LightAdd to list Details
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
Comparing CrystalsAdd to list Details
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.
