Focusing on energy changes
Classroom Activity for 11-14
What the Activity is for
The purpose of this activity is to emphasise the point that care must be taken when selecting aspects of a process to describe in terms of energy.
What to Prepare
- Two interactive objects, which offers a choice of changes to study (download below)
We provide an image, but you can use any single image that you want, so that you can explore the process of
choosing what to study in your own context.
What Happens During this Activity
Launch the first interactive object, then discuss the placement of the box that decides what you'll study and describe. What are you going to include and exclude? Why are you including or excluding those pieces?
If you want to use your own photograph, first export the interactive object, then replace the image file (image.jpg) with your own image. Your own image must be named image.jpg.
Launch the second interactive object, then choose where to place the box, so defining the change carefully. Discuss where you will start and where you will end the change as you run through the photograph sequence. What are you going to include and exclude? Why are you including or excluding these processes?
If you want to use your own photographs, first export the interactive object, then replace the image files with your own. Your own must be named image1.jpg, image2.jpg, image3.jpg, image4.jpg and image5.jpg. You'll find it helpful if the images record exactly the same piece of space but at different times.
