Today we will be conducting an experiment to explore the lengths of a shadow in a day.
You will need:
- your science scrapbook
- a pencil, ruler, eraser
- the resources I will give you 🙂
What we are going to do:
- Discuss our previous lesson – what happened to our shadows on the netball court last week when we reviewed them? Why did this happen? When were the shadows at their longest and shortest?
- Let’s discuss variables and controls – who has heard of these terms before?
- Let’s discuss change, measure and observe, and keep the same – what does this mean? In this experiment, what is going to change, what will be measured and what will stay the same?
- Fill out the Shadow stick investigation planner. You can work with your team however EVERYONE must have their own copy in their book.
- Let’s discuss how we are going to set up our experiment – who has some ideas? How are you going to record your observations? What is going to affect the length and direction of the shadow?
TIME TO SET UP YOUR EXPERIMENTS – remember to take a photo each time you visit and record your results on the ‘recording and presenting results’ sheet.
Last step – explain your results on the ‘explaining results’ sheet.
