The students need to be able to interpret scientific notation. This is part of the pre-algebra core curriculum. However, students may not be very comfortable using scientific notation, and a concept review prior to conducting the computer investigation might be useful. It is also important that students have some graphing skills. A review of what to do with the independent and dependent variables, and the constants may also be in order.
All teachers have unique and original ways to introduce new topics and ideas.
Presented here are a couple of ideas for introducing this lab activity. Conduct a class discussion prior to beginning the computer investigations. Accept all answers and explanations. Lead the discussion towards the idea of objects with different masses having the same energy. Ask the students to write down their answers to these questions to refer to later.
