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...

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...

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...

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...

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.

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...

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...

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...

Can you distinguish physical changes from chemical changes? After reading a brief summary of both types of changes, you'll be presented with some examples and asked to identify them.

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...

After observing a demonstration of a chemical reaction between a burning candle and the oxygen in the air, young scholars use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

[Free Registration/Login Required] Explore how heat and temperature relate to phase changes.

Students will learn about reversible and irreversible changes in materials in this lesson.

Join Leander in his chemistry lesson, and learn about the change of different types of substances.

Explore the differences between chemical and physical changes, including some examples at the atomic level.

Can you distinguish physical changes from chemical reactions? You'll be presented with a number of pictures and asked to identify those which are examples of chemical reactions.

Students observe reactions of liquids with different known powders in this lesson. Unknown powders are then identified using characteristic chemical changes.Site includes a procedure, teacher instructions, and video instruction.

Do you know the difference between a physical and a chemical change? This interactive tutorial will explore these concepts!

This activity explores how students could use chemical changes to identify unknown substances. Lab activity includes student and teacher worksheets.

Twelve interactive chemistry lessons about chemical changes complete with handouts and animations.
