In order to unlock this badge, you will need to individually plan and come up with a suitable purpose and a detailed, step-by-step method for an appropriate investigation.
Range:
- Write a statement that describes the purpose of the investigation. The statement can be written in the form of a question or a statement of intent but should name the variables and their units, if appropriate
- Draw and label an appropriate diagram of the equipment setup
- State how the variables will be controlled and measured
- State appropriate units for the variables
- Describe detailed steps of how to carry out the investigation so that it could be carried out in exactly the same way by another Year 9 student
- Describe how the method will be repeated
Exemplars:
Aim:
What is the average speed of flying saucers passing MAC?
Is there a relationship between the number of wings and the number of legs an insect has?
What effect does saltwater have on the germination of radish and lettuce seeds?
The aim of this experiment is to discover which material is the best insulator. 4 different materials will be used: bubble wrap, polythene, aluminum foil and cotton.
Method:
- Before starting, collect all of the necessary equipment.
- Cover the containers with the different materials, attach with sellotape and place them in the same place.
- Fill a separate container with cold water and place all of the thermometers inside. After 4 minutes, check that all the thermometers are displaying the same temperature.
- Whilst the thermometers are being checked, heat a container containing 2.5L of water and switch off when boiled.
- Whilst you are waiting for the water to reach boiling point, place the thermometers into the 5 individual containers.
- When the water is ready, pour 500 ml of boiling water into each container. After 1 minute record the temperature of the water in each container. Record the temperature of the water in each of the 5 containers every two minutes for 15 minutes.
- Collect results in a table and display as a graph.
