Focus Questions

For use in a classroom, pause the video and ask this question:

[Pause the video at 4:14] Emily noticed that if she increases the slider, the orange part starts to appear larger than the rest of the garden. If she decreases the slider, the orange part appears much smaller. Did you notice that? Why do you think that is? 

Supporting Dialogue

[Pause the video at 2:00] Use the applet yourself (or rewatch Mauricio and Emily using the applet). Tell a neighbor one thing you notice about the areas you see and one thing you wonder about.
