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 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...

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

Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.

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 plan is one that...

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...

Learners, in groups, combine given materials from an everyday kitchen until a chemical reaction occurs and record the reaction time.

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, students burn magnesium and record the mass. Students list five chemical reactions they see everyday.
