1. CAT OR BATMAN?

2. Design an experiment to answer these questions?
How do shadows form?
What do shadows tell us about light?
Design an experiment to answer these questions?

3. Aim To see how shadows are formed and behave
Diagram

4. The variables? The size of the shadow is the dependent variable.
The distance from the object to the screen is the independent variable.
We will control the distance from the light source to the object.

6. Drawing a graph checklist:
Title
Label and Units
Appropriate units on x axis and y axis
Axis and sensible Scale
Points plotted accurately
Lines of best fit drawn
Writing a conclusion:
Conclusion checklist:
er/er statement.
Use of data to exemplify trends.
Discuss whether your data is good enough to draw a conclusion.
Discussion of science to back up the trends observed.

7. Plot an appropriate graph
Put the dependant variable on the y- axis Put the independent variable on the x-axis. Size Sharp pencil Label both axes – quantity (unit) Plot as carefully as you can. Draw line of best fit.

8. Complete a results table
Plot a suitable graph
Produce a conclusion
-what pattern does your graph show
-back it up with data
-use the science to explain the pattern
