1. Howden School and Technology College 7J Electrical Circuits Whats in the black box?

2. Howden School and Technology College Objective To describe and explain what circuits are in the black boxes

3. Howden School and Technology College The Black Box By unscrewing the bulbs can you work out what the electrical circuit looks like? Record your observations

4. Howden School and Technology College Obtaining your evidence LevelIn my experiment, I can....... 3 use simple equipment to make measurements e.g. length and mass make basic observations 4 make enough measurements and/or observations for the investigation 5 make a series of measurements and/or observations that are accurate spot that a result is odd and repeat the experiment

5. Howden School and Technology College Results When you have finished testing the Black Box draw the circuit you think is inside the box

6. Howden School and Technology College LevelIn my conclusion, I can....... 3 give some explanation for the patterns and observations 4use scientific language to: explain the patterns shown in my results link the conclusion to my prediction 5use knowledge and understanding of level 5 science to : explain the patterns shown in my results use these patterns and any other results to draw conclusions Making a conclusion
