Apply knowledge and skills related to simple machines, light energy and systems, performance, and fair testing.
Renewable energy sources can be captured and used in many ways. A variety of mechanisms can be powered by a renewable energy source.
The school’s basketball team needs a lighting system to enable them to train after dark.
To help in the design process, instruct students to look at the picture on the Student Worksheet and read the accompanying text.
Let students search the Internet to learn more about the appearance, structure and function of different sorts of lightning systems and renewable energy light applications.
Discuss the constraints and functions they will have to take into account as described by the task.
Your task is to design and build a prototype solution for a lighting system, powered by a renewable energy source.
Make sure it can be used after dark.

Fair Testing and Fun
While the activity is in progress, encourage students to relate their knowledge, skills and understanding to the task at hand by asking:
Which renewable energy source would be most appropriate to use?
How will your court lights work?
What different sorts of elements will you need?
How will you ensure that it is easy to use?
How will you ensure that it is reliable?
When finished constructing, encourage students to reflect on both the product that they have produced and the processes they have used by:
Carrying out tests to evaluate the performance of the court lights:
- Which renewable energy source did you find most appropriate to use and why?
- How easy is it to use?
- How reliable is it? To test if the court lights can light after dark, place them in a dark room and time how long they can stay on.
- What are its limitations, if any?
Recording their design by drawing or taking digital photos.
Adding notes to describe the way the model works and how this might be improved to get better performance.
Writing briefly on what went well in their design task and what they could have done to improve it.
