Evaluate the effectiveness of the method. Independently design a practical. Outcomes Use the terms interval, range and precision correctly. 0o0o 180 o 135 o 90 o 45 o Writing A Method What do you think we might be investigating today? What do you think will happen?

Evaluate the effectiveness of the method. Independently design a practical. Outcomes Use the terms interval, range and precision correctly. Learning Outcomes Use the terms interval, range and precision correctly. Evaluate the effectiveness of the method. Independently design a practical that investigates how the angle affects the time taken for a splint to burn.

Evaluate the effectiveness of the method. Independently design a practical. Outcomes Use the terms interval, range and precision correctly. 0o0o 180 o 135 o 90 o 45 o

Evaluate the effectiveness of the method. Independently design a practical. Outcomes Use the terms interval, range and precision correctly. 0° 45° 90° 180° 135° The range is the lowest to the highest. The interval is the distance between each value. What is the range? What is the interval?

Evaluate the effectiveness of the method. Independently design a practical. Outcomes Use the terms interval, range and precision correctly. Prediction This is what you think will happen. I think that as I increase the angle of the splint the time it takes to burn will.... I think this because....
