You can use WeScheme if you cannot install DrRacket. For example, if you have a Chromebook for your home computer.

Omit the (require picturing-programs) line.
(Chapter 3)
Instead of copy and pasting in a picture, you need to copy the link for the image and use bitmap/url like this:
(bitmap/url "https://www.what-dog.net/Images/faces2/main004.jpg")(Chapter 6) Inside big-bang you need to use the phrase to-draw instead of on-draw that we use in DrRacket.
(define (draw-handler model)
(overlay model (empty-scene 300 200)))
(define (tick-handler model)
(scale 1.01 model))
(big-bang (circle 10 "solid" "green")
(on-tick tick-handler)
(to-draw draw-handler))
