Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

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,...

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

In this states of matter worksheet, students are given a summary of the particle arrangement, the motion of particles, the properties of particles, and models of particles in solids, liquids, and gases. Melting, evaporating, boiling,...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

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....

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final instructional activity in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter...

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-lesson unit on dissolving, this installment investigates the effect of temperature. If you consult the...

Whether you're using a collection of Dr. Seuss books to teach basic math skills like counting, adding, and subtracting, or exploring the different states of matter by melting a crayon with a hairdryer, a series...

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson plan, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over...
