Intro: Finding hidden pictures within pictures has always been fun. Use your whiteboard or use a projector and screen for this activity.
Activity: During the August 21 eclipse a picture of the ISS (international space station) can be seen in the sunspots. Take a moment with your students to discuss this awesome picture and to ask students to find the ISS.
If you want to talk about how international scientists cooperated to build the ISS, or how they work together on the ISS now is the time.
This is a doc file so that you can click to the website easily. Find the ISS near the bottom of the curve. Enlarge if you want to see the ISS more clearly. Very cool.
