Substances And Chemical Reactions

Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...

If you have taught the first lesson in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known and...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Though the publisher designated this unit for use with third through eighth grades, this particular lesson would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

Students participate in a science experiment to understand that matter takes up space.  In this matter lesson, students experiment with solids, liquids and gases to recognize that matter is everywhere. Students make observations and...

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This instructional activity can stand alone, but is best used...

Third graders experiment with common household liquids and solids. In this chemical reaction instructional activity, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon...

Scientists participate in a variety of hands-on experiments in this ten-day unit on the three states of matter. Lessons incorporate literature, a-v materials, and poetry to help students differentiate between solids, liquids and gases.

Students learn about solids, liquids, and gases in this interactive slide show. Animated cartoon characters explain concepts having to do with properties of matter. A self-checking quiz follows the lesson.

Students explore solid, liquids, and gases. In this science lesson plan, students distinguish similarities and differences of matter and recognize that different states of matter may appear in one substance.
