Typically completed by 10-14 year olds, students work collaboratively on a five hour project or challenge in self-managed groups. During the project, they use a CREST Discovery passport to record and reflect on their work. Afterwards, students communicate their findings as a group presentation.
Each pack provides teaching guides, kit lists, example timetables and suggested starter activities to help you run your day. Find out more about CREST Discovery Awards.
Electricity Fact file: Movement There is potential to convert all sorts of different types of human movement, or kinetic energy, into electricity. This could include walking, writing, or even opening a door. Many new technologies are being developed to use the examples described below. In this workshop you will work in pairs to investigate ways of meeting your school electricity needs using local sources. You should make notes as you go through this workshop as you will need to share your findings with your teammates. Cycling Bicycles can be used to generate electricity by connecting the rear wheel to a motor. The bike is stationary so when a person pedals, the rear wheel turns and this motion drives the motor to produce electricity. Appliances can be directly connected to the motor, however if the person stops cycling they will stop working! Another option is to connect the bike to a battery: once fully charged it could be connected to a device to give a constant output. This set up could be installed in a school gym, or even in classrooms. The handlebars at the front could be replaced with a desk to allow the person to continue working. Walking Students will walk quite far around school throughout a week. There are materials available that could be used in the floors of corridors and classrooms that use the motion of these footsteps to generate electricity. These materials are called piezoelectric. They generate electricity when they are pressed or squeezed. They are mainly crystalbased structures, for example quartz and topaz. If you put these materials into the floors of schools, each footstep pressing down on the floor would contribute to generating electricity.
Small movements The human body makes lots of small movements, resulting in motion. For example, whilst walking along wearing a backpack the backpack will tend to move up and down. A small converter could use this motion to generate electricity. This could take the form of a small spring in a box made of a piezoelectric material. When the body moves and produces kinetic energy, this is then translated into mechanical energy within the spring, resulting in a push on the piezoelectric walls of the box. This type of generation would produce much less electricity than cycling or walking but it may still be enough to power some personal devices, or to charge a small battery. There are lots of other small movements made by the human body that could be used to generate electricity.
