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.
Surface Area
Source Institutions
In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.
Make Your Own Sculpture Dough
Source Institutions
In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.
Look-alike Liquids
Source Institutions
Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.
Universal Indicator Rainbow Trout
Source Institutions
In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Changing the Density of a Liquid: Adding Salt
Source Institutions
Learners see that a carrot slice sinks in fresh water and floats in saltwater.
Newspaper Collage
Source Institutions
In this activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.
Colors Collide or Combine
Source Institutions
Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.
Rainbow Density Experiment
Source Institutions
In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
Which Powder is It?
Source Institutions
In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.
Exploring How Liquids Behave
Source Institutions
Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Universal Indicator Rainbow Trout
Source Institutions
In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.
Great Balls of Goop
Source Institutions
In this activity, learners mix white craft glue and borax solution together to produce a surprising new material: GOOP!
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.
Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
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.
Beam Me Up!
Source Institutions
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.
