Ice Cream
Students explore the concept of the colligative property. Through experimentation, students lower the freezing point of a liquid in order to create a solid by using household ingredients to create ice cream.
Curated OER
Run-off Race
Students create wetland models in pans and use them to experiment to see how plants help slow the flow of runoff water and keep our waterways clean.
Curated OER
Understanding Waves
Students perform 3 hands-on activities to help them explain the terms "crest" and "trough" as related to sound, water, and light waves. All three waves types have troughs and crests. The activities use toys to demonstrate the properties...

Plastics and Rubber: What's the Difference?
Students observe how to classify things into groups based on physical properties. In this plastic and rubber lesson students group and sort items to help them to better identify properties.
Curated OER
River Study
Students study physical features of a local stream. They study how to identify water features on topographic maps.
Curated OER
Oxygen vs. Air Pressure
Learners conduct an experiment to determine if water level is affected by a change in oxygen level or air pressure.
Curated OER
Activity #1 Reactions: Chemical or Physical?
Students distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. Pupils also...
Curated OER
Physical vs. Chemical Changes
In this chemical and physical change worksheet, students are given details about chemical and physical changes. They are given 2 examples using water and salt and they identify 15 statements as chemical or physical changes. Students...
Curated OER
Using Bubbles to Learn about Light Interference
Students explain the wave properties of light.

The Chemistry of Bigger Bubbles
Fourth graders explore properties of bubbles. In this lesson about bubbles, 4th graders perform an experiment. Students analyze the properties of bubble making substances and surface tension. Students create a square bubble. Students...
Curated OER
Science: Floating and Sinking Objects
Second graders discuss why some objects float while others sink. They examine various objects and predict whether or not they will sink or float. Students discover the properties needed for objects to float.
Curated OER
The Unmixables: Investigating Immiscible Liquids
Students build an understanding of the properties of liquids and research the immiscible properties of different milks through group experiments. For this immiscible liquids experiment, students investigate what happens when certain...

Disposable Diaper Comparison and Mystery Powder Identification
Students investigate which diaper is the most absorbent. In this chemistry lesson, students calculate how much water is absorbed by diapers. They identify an unknown powder based on physical and chemical properties.
Curated OER
Ocean Murals
Students identify characteristics of water. They describe the process by which light decreases and pressure increases as water depth increases. They demonstrate the principle of water pressure in a small group experiment.
Curated OER
States of Matter
Fourth graders define the term matter. They compare properties of solids, liquids, and gases. They describe how matter changes from one state to another. They classify objects as either solid, liquid, or gas.
Curated OER
Polymers-Greaaaaaat Biiiiiig Molecuuuuuules
Students explore polymer properties. In this lesson about polymers, students perform an experiment to understand polymers, their properties, and that they are formed from small molecules. Students role play pretending they are polymer...
