Looking At Variables
Learners predict and test different variables that would effect sugar cubes dissolving in water. In this dissolving lesson plan, students have 4 petri dishes with 4 different variations of sugar cubes and water. They predict which will...
Curated OER
Mixtures
Students experiment with solutions. In this mixtures and solutions science lesson plan, students work in groups of three to perform an experiment. Students place a sugar cube in three glasses, and observe and record the different rates...
Curated OER
Rock Candy
Fourth graders observe and demonstrate the physical change of dissolving sugar in water and evaporating the water to examine the physical change that has occurred. They discuss physical changes and solutions, and make rock candy,...
Curated OER
Rate of Solubility
Students investigate factors affecting the rate of solubility. In this rate of solubility lesson plan, students experiment by crushing, heating and cooling solutes and solvents to see how the solubility is affected. For each situation,...
Curated OER
Solutions and Suspensions
Students explore matter by conducting an in class demonstration. For this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't...

The Lifesaver Descriptive Writing Lesson
Students observe all of their senses and practice descriptive writing while eating Lifesavers. They write silently about what they are tasting, smelling, and hearing until the candy is dissolved.
Curated OER
Learning About Matter And Energy
Learners learn about matter and energy. In this science lesson plan, students gain an understanding of the properties of matter and energy as they discover that some things float, some things dissolve in water and discuss that energy can...
Curated OER
Reuse, Reduce, Recycle Paper
Young scholars experiment with recycling paper. In this paper recycling lesson, students conduct an experiment in which they dissolve newspaper in water and cornstarch to make new pieces of paper. They add color or flowers to the new...

Under Pressure
Sometimes a little pressure isn't a bad thing! A collaborative lesson uses models to demonstrate how air pressure inflates and deflates the lungs. Participants use everyday materials to create models of the chest cavity to simulate how a...
Curated OER
Reversible and irreversible changes
Students experiment with solids and liquids to find which solids will dissolve in water. This dissolution and mixtures lesson can be completed online or in class as all materials are connected to the lesson plan for both settings.

ACTIVITY 6: MAKE A FOSSIL MOLD AND CAST and ACTIVITY 7: HOW BIG WERE PREHISTORIC ANIMALS?
Instructions for two terrific ancient history lessons for your primary paleontologists are provided in this resource. The first involves the creation of fossil cast replicas using plaster of Paris. The directions are detailed, but the...
Safe Drinking Water Foundation
Demonstration of Water Pollution
In this teacher-led demonstration, your young environmentalists will observe and record how different types of water pollutants look when they are combined. From here, individuals will develop a hypothesis on how the water can be...
Curated OER
Basic Vitamins: Water-Soluble and Fat-Soluble
An incredibly thorough lesson on vitamins, and how to keep one's body at peak health. Learners access a variety of excellent worksheets embedded in the plan that have them consider raw vs. cooked foods, a vegetable nutrition summary,...
Curated OER
MEASURING THE DENSITY OF WATER
Students perform an experiment to measure the density of tap water vs. salt water.
Curated OER
Investigating the Change
Sugar crystal growth is observed as an example of physical change and cabbage juice pH indicator is used to demonstrate chemical change. The crystal growth is tracked over five days. The cabbage juice experiment is involved and can also...

Global Climate Change and Sea Level Rise
Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...
American Chemical Society
Matter on the Move
Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...
Curated OER
Alka-Seltzer Cannons
The scientific method is emphasized in this engaging and exciting chemistry lesson. Learners get to create Alka-Seltzer cannons out of film cannisters, water, and Alka-Seltzer tablets. Carbon dioxide gas builds up inside the cannister,...
Curated OER
Liquid Rainbow
Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.
Curated OER
Metamorphic Magic!
Students explore the steps involved in the formation of metamorphic rock as they prepare a cookie receipe. As part of the process, sedimentary rocks are created and changed through heat to a metamorphic cookie.
Curated OER
Simplified Botany--Leaf Chromatography
Students investigate the different pigments contained in green leaves by completing an experiment that strips away the chlorophyll and separates the pigments left behind.
