Matter on the Move
Source Institutions
Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.
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.
Comparing the Density of an Object to the Density of Water
Source Institutions
Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.
Defining Density
Source Institutions
In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.
Changing the Density of an Object: Changing Shape
Source Institutions
Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.
Comparing the Density of Different Liquids
Source Institutions
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.
Bubble Trouble
Source Institutions
In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.
Molecules in Motion
Source Institutions
In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.
What Counts in Bounce
Source Institutions
In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.
Water: Clearly Unique!
Source Institutions
In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.
Does Size Make a Difference?
Source Institutions
In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.
New Sense about Cents
Source Institutions
In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.
Avogadro's Bubbly Adventure
Source Institutions
In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.
Milli's Super Sorting Challenge
Source Institutions
In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.
Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.
Making Recycled Paper
Source Institutions
In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.
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.
Solubility Test
Source Institutions
In this activity, learners apply a dissolving test to known crystals to identify the unknown. Since the unknown is chemically the same as one of the known crystals, it should dissolve similarly.
Using Color to See How Liquids Combine
Source Institutions
Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.
Spaghetti Strength
Source Institutions
In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.
