Since you can't go to the comet, bring the comet to you. Young scientists build models of comets using everyday materials and then participate in a simulation of the interaction between the comet and other bodies in the solar system....

One way to study something is to try to replicate it. Young scientists do just that as they use solutions to recreate mineral structures on a dwarf planet. They make solutions with different types of salt, evaporate them, and observe the...

Heat is a gateway to change. While exploring the properties of baking powder, pupils learn that some heat-related changes are permanent. Using an animation, the lesson plan uses chocolate chip cookies as an example.

It's heating up—and cooling down—in here! A hands-on lesson allows learners to experiment with melting and freezing butter to observe changes as a substance transitions between liquid and solid form. They also view an animation that...

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. 

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...

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...

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 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...

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 of 11 fun activities...

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.

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