Young scientists get to the heart of the matter as they complete this worksheet on the properties of solids, liquids, and gases.

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.

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...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

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.    

What's the solution to gaining insight into your class' progress? Give this brief quiz a try! Part 10 of a 14-installment series on states of matter tests learners' skills in the areas of dilution and the properties of water,...

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...

Pour on the knowledge with an engaging states of matter interactive! Young physical scientists view the atoms within a liquid to explain what gives a liquid its unique properties. The resource allows users to highlight and observe two...

Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

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

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Here is part two of a two-part lesson 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 one hands-on...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Young geologists discover the important role that rocks and minerals play in our everyday lives through this series of hands-on activities. Starting off with a lesson that defines the difference between plants, animals, and...

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....

Explore the unique characteristics of polymers. A complete lesson begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

Time to show what they know! Module five in a 14-part series about solids, liquids, and gases redirects to an interactive quiz. Learners test their skills on topics such as states of matter, phase changes, and Brownian Motion. With...

No need to tread lightly on this piece of tire rubber! Polymer science pupils observe the behavior of rubber with an interesting interactive. Users apply three different levels of force to a sample, then watch how they affect the polymer...

Plastic is fantastic! But, why does it behave the way it does? Science sleuths investigate the behavior of plastic in response to applied forces using an interactive. The resource allows users to bend a sample of plastic using three...

Why are solids, well ... solid? Take a peek inside a solid substance with an easy-to-use interactive. Science sleuths examine the motion and position of the atoms that make up a solid before drawing conclusions from their observations.

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

Take young geologists on an exploration of the rock cycle with this six-lesson earth science unit on rocks and minerals. Through a series of discussions, demonstrations, and hands-on investigations your class will learn...
