Lesson 10

Lesson Objectives...

• Students apply scientific ideas and evidence (property data) to construct an explanation for whether the gas(es) produced from water using energy from a battery were made of the same particles (patterns) as those produced from heating the water.

Resources for Lesson 10...

Adding Energy to Water with Electricity...

Make observations from the video of energy being added to water from a battery.  Test tube A is on the left.  Test tube B is on the right.

Analyzing the Gases from Adding Energy with Electricity to Water...

Make observations from the video of the analysis of the test tubes obtained from capturing the gas from adding energy with electricity to water.

Properties of Some Common Gases

Use the data table to identify properties of common gases.  

What we figured out this lesson...

• Two different gases with different properties are produced from adding energy from a battery to water.

• The particles that make up these different gases must be different from each other; they must also be different that the ones that were produced from heating water.

• The matter that makes up all of the substances must come from matter that made up some of the original water particles.
