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...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

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...

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.

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

Use STEM activities within the class to provide connections to concepts. The resource includes activities that range from working with buoyancy to building rockets and launching them. Other activities involve the engineering design...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

Learners explore the emotional and nutritional needs of teenagers in a six-lesson unit, which covers such topics as food sources, cooking skills, emotional well-being, and the positive effect of food and family occasions. 

Combine science and reading skills with a reading comprehension exercise. Kids read four paragraphs about energy conversion and answer some reading comprehension questions about the information they have read.

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Through an instructional video, games, and activities, students explore three types of change matter makes: physical change, in which only the shape of the matter changes; physical phase change in which matter changes to a different form...

A module that provides the definition of chemical property and examples of the chemical properties of matter using explanations, pictures, and review questions.

The resource from Khan Academy and the Association of American Medical Colleges provides study content for the MCAT. This resource provides practice uestions related to phase changes during lyophilisation, or the process of freeze drying.
