Substances And Chemical Reactions

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.

If you have taught the first lesson plan 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...

Students identify and observe chemical changes. In this chemical reaction lesson, students use various substances to observe the characteristics of a chemical change. This lesson has three activities including an experiment with baking...

By both demonstration and hands-on investigation, physical science fanatics come to know that some materials react when they come together. Adding vinegar to both baking soda and to baking powder, the difference between the two is clear....

Meant to follow an activity in which young chemists identified an unknown substance by chemical reactions, they now take their data and use it to determine which materials combine to make up baking powder. This lesson is one that can be...

Make a Halloween pumpkin foam at the mouth! Using hydrogen peroxide, toothpaste, and yeast, you can recreate this chemical reaction in your classroom. It can lead to a discussion of the way ingredients mix together to make a new...

Make a Halloween pumpkin foam at the mouth! Using hydrogen peroxide, toothpaste, and yeast, you can recreate this chemical reaction in your classroom. It can lead to a discussion of the way ingredients mix together to make a new...

After viewing a short video about property changes, preteen scientists watch you combine different materials, and then perform two of their own experiments. For each demonstration or activity, they are to determine whether a physical or...

Students use the scientific method to create and observe a chemical reaction. They observe and describe the physical properties of three substances, make a hypothesis, record the results, and explore various science websites.

Students conduct various labs to experiment with physical and chemical reactions. They also consider the 4 ways in which a reaction can be sped up (concentration, surface area, temperature and catalysts.) students conduct experiments on...
