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...

Your physical science class learns that there are three states of matter, and that adding or removing heat can cause it to change from one state to another. By the animations, printed information, and discussion between RJ and Zoe, they...

What better time to reinforce a concept than when you're eating? Boost scholars' knowledge of the water cycle with an eye-catching placemat featuring playful raindrops and bright colors. 

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.

Explore the states of matter without the mess or expensive equipment in a compact, informative activity. Scientists watch as the narrator explains the three states of matter using a glass of ice and soda in an animated video that...

Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...

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...

Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

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.    

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...

Take an energetic ride through the phase changes of a water molecule in a compact activity. Young scientists learn about the phases of matter and discover the role of thermal energy in governing phase changes while watching a short...

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...

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.

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to learners their different roles in the activity, the teacher reads aloud a...

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...

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...

Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

Who likes magic shows? In the fourth of five lessons, pupils view a scientific magic trick. The ball fits through the ring easily, but then moments later, it won't pass through anymore. What changed? Can we reverse the change? Scholars...

In a friendly, casual conversation on the beach, two animated teens discuss the periodic table. Assign this video to be viewed at home by physical science fans. After viewing, they can write definitions for key vocabulary terms and take...

Mix it up at a party as Sam and Zoe discuss heterogeneous and homogenous mixtures and solutions. Follow this film by allowing your class to put together individual snack foods to make their own mixture!

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based instructional activity includes a range of learning experiences, from experimenting with the rate at...

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....

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...
