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...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

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...

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...

How tall is the Empire State Building? Lead your class through a collaborative estimation activity to determine the number of quarters it would take to reach the top and teach the following concepts: human capital, human resources,...

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities 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....

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

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...

Feeling high is not the only side effect of abusing prescription opioids. Middle and high schoolers learn more about specific painkillers, including Fentanyl, Oxycodone, and Clonazepam, as well as their common brand names and extensive...

Turn your students into young tree-tectives with this fun science investigation into the life of trees. To begin, a class volunteer gets dressed up in a tree costume as the different parts of trees are introduced. Then, the class...

In 1879, Sir William Crookes discovered the fourth state of matter, plasma. The presentation covers states of matter, phase changes, density, pressure Pascal's Principle, buoyant force, Archimedes' Principle, Bernoulli's Principle,...

Get the ball rolling with this upper-elementary science unit on forces and motion. Offering over three weeks of physical science lessons, this resource is a great way to engage the class in learning about simple machines, friction,...

Test takers stressing out over the upcoming exam? Help them prepare for the AP Physics i exam with this fast-paced video that includes a complete guide to everything related to kinematics. Also included are some common errors...

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...

Some say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the lesson.

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.

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

Entropy, it isn't what it used to be. Presentation includes kinetic-molecular theory, heat and internal energy, thermal equilibrium, temperature scales, laws of thermodynamics, entropy, latent heat of fusion, specific heat, calorimetry,...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

Combine a fantastic review of primary source analysis with a study of Captain John Smith's influence on the Chesapeake Bay region in the seventeenth century. Your young historians will use images, a primary source excerpt, and maps...

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