Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Who knew that learning about the states of matter could taste so sweet? This fun hands-on lesson captures the attention of learners as they use what they know about solids, liquids, and gases to create their very own batch of ice cream.

Here is part two of a two-part instructional activity in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and...

Watch red cabbage juice turn green. Pupils first watch a video that takes them through the process of creating red cabbage juice. They then add various solids and liquids to the juice and use the color change to determine whether the...

Learners investigate melting and cooling in a range of materials.

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.

Students explore the three forms of water and observe how it changes from a solid to a liquid to a gas. The concepts of condensation, evaporation and the introduction to the water cycle form the basis of this lesson.

Mold your learners into materials engineers. Using glue, Borax, and water, scholars create a viscoelastic material. But your class might know it by another name—Silly Putty.

It's time to get a little silly with this fun primary grade science activity. By simply combining two liquids, white glue and corn starch, a strange solid is formed, commonly known as silly putty. To ensure everything goes smoothly,...

The illustrations of Ezra Jack Keats in The Snowy Day inspire young artists to examine shapes in illustrations and to use these shapes to create their own watercolor resist painting.

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

What has more energy than a room full of pupils after a fire drill? This lesson plan! Explore the changes in energy during different chemical reactions, discover why some reactions feel cold and others feel hot, and tackle the concept of...

Pour a solid foundation of engineering into the minds of future engineers. Scholars take part in three activities to learn about civil engineering. They build a model of a cable-stayed bridge, conduct an experiment to see the effects of...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity,...

Students explore the states of water. In this water states lesson, students observe ice over time and the changes that take place. Students read a related text and draw their observations in a journal entry. Students discuss the...

Second graders identify the three states of matter by examining fishbowls with various contents. They discuss their observations and the characteristics of matter in each state. Pupils read the story The Rainbow Fish and look for...
