Metal Reactions
Source Institutions
This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.
Best Bubbles
Source Institutions
In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
Guar Gum Slime
Source Institutions
In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.
Concentrate!
Source Institutions
In this investigation of reaction kinetics, learners alter the amount of iodate solution mixed with the same amount of starch solution.
Test Density with a Supersaturated Solution
Source Institutions
Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.
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.
Color Splash
Source Institutions
In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.
Law of Conservation of Mass
Source Institutions
In this chemistry activity, learners explore whether matter is created or destroyed during a chemical reaction. They will compare the weight of various solutions before and after they are mixed.
Oil and Soap
Source Institutions
Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.
Crystal Stencil Stars
Source Institutions
In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.
Cauldron Bubbles
Source Institutions
In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.
Sodium Acetate Hand Warmers
Source Institutions
In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.
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.
Carrying Charges: Testing for Conductivity
Source Institutions
Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
Double Replacement Micro-Reactions
Source Institutions
In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.
Salt Painting
Source Institutions
In this art meets chemistry activity, early learners discover the almost magical absorbent properties of salt while creating ethereal watercolor paintings.
Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).
