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.

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...

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...

Looks don't tell the whole story. Young experimenters explore reactions with substances that look similar. They observe the reactions that take place when combined with baking soda and use indicators to conclude they react differently...

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...

Fifth graders, in groups, complete two activities in which various substances are combined, resulting in a very different substances. They discuss reactants and products and chemical reactions.

Students investigate chemical reactions. In this chemistry lesson plan, students burn magnesium and record the mass. Students list five chemical reactions they see everyday.

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...
