Engagement Day 1 (5 to 15 minutes):

Students are told that NASA has discovered a large asteroid is going to hit the Earth with enough force to cause catastrophic damage. Much of the polar ice caps will melt and many will die. You are to design a ship to save yourself and nine others (10 total) and search for survivors on other continents. If fossil fuels are not available at this time, due to the catastrophe, what other sources of energy is available to power the ship’s instruments (lights, computers, etc.)?

Discuss with the groups of students (number of students in group is decided on by teacher) different power sources that are available to move ships

If you were going to design a cargo ship what power source would you use for the ship? What pros and cons do you see for each power source?

How would you go about storing that energy? What would be needed?

biomass, and solar. Students should also be researching

types of batteries and how they are made and how they store energy.

Day 2 (45 to 90 minutes): Have students work in groups

formulating a chart with explanations of how the energy source produces usable energy, and pros and cons for each energy source.

After discussing the chart the groups will then decide what energy source they would recommend for the ship.

The group will then use their knowledge of batteries to experiment with different materials to attempt to create a working battery and measure the voltage using the voltmeter probe.

Students will discuss how to make the battery more powerful and then create a new battery and measure the volts again.

Students must then determine how many of their batteries would be needed to power the entire ship’s electric motor.

Students will determine what types of light sources their batteries can power; and which type of circuit allows for the most lights to be lit.

(E) design and analyze electric circuits

Explanation The choice in energy source is very important and depends on many constraints such as cost, pollution, and if the source is renewable or not. Students will need to take into account all of these stipulations to make the best decision to power their ship. They must then be able to explain their decisions to their peers. The turbidity test of the water goes along with the pollution that energy sources can create. Turbidity is the cloudiness or haziness of a fluid caused by individual particles (suspended solids) that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of water quality. In drinking water, the higher the turbidity level, the higher the risk that people may develop gastrointestinal diseases.

Safety Notes Do not ingest water samples. Be careful with water around electrical equipment. Be careful with chemicals and electric sources.

Extension 1 Website:


Pamphlet for Energy SourceStudents will need to create a colored pamphlet to sell their energy source to prospective buyers. A PowerPoint presentation can also be made to add to the explanation.Extension 2 Determine the Turbidity of the Drinking WaterStudents will examine water samples from different parts of the school and from people’s homes to check for turbidity (amount of particles suspended in the liquid). With many energy sources, pollution is a concern and can cause a high turbidity rate.
