Have students make their own "business cards" (use the school's address and phone for privacy if you like) using their own paper, pens and markers. They can even include a "business" of their own creation.

Ask a student to describe a Global Positioning System device. Brainstorm interesting uses for one.

Have students brainstorm how the world seems to be designed for adults, and explain what they would like to see to make them feel more comfortable or important.

What If: falling rain suddenly froze in mid-air?

Give each student a meter of string and a piece of heavy paper or cardboard. Let them cut a 10 cm. circle, punch a couple of holes toward the center (like a button) and thread the string through to make one of those things you made as a kid out of real buttons, that spins and whizzes when the string is pulled just right. Have them colour the paper with markers or crayons, trying spiral patterns or primary colours that will blend into third colours.

Play celebrity heads, using everyday objects (nouns) instead of celebrities.

Have students try to count a minute in their heads and put up their hand. Use a timer to keep it objective.

Going around a circle, get each student to name a different fruit or vegetable. If they say one that has already been said, they go out.
