- Due Wednesday March 27: one of 41, 43, 44; and the answers to the questions in the following activity:
- (This activity is borrowed from the Math 124 Wiki)
- Take one of the crosses and tape together two opposite "arms" into an untwisted loop. Then tape the other two arms in another untwisted loop (if you taped the first loop on one side of the strip crossing, bend the other loop to the other side). The result will look like a twisted figure eight. Cut one loop down its middle (that is, cut along the length of the loop). What do you get after cutting one of the loops? Now cut the other loop down its middle. What do you get after cutting the second loop?
- Take the second cross. Again tape opposite ends into loops. This time make one a plain loop and one a Möbius band. What do you think you will end up with after cutting both loops? Cut the loops to find out. Report the result.
- Using the third cross, again tape opposite ends together to make two loops, this time twisting both loops into Möbius bands. What do you think you will end up with after cutting both loops? Cut the loops to find out. Report the result. In each case, make sure to report how many pieces you get and how many twists each piece has. Check carefully!
Cut six strips of paper, each wide enough that you can cut them in half lengthways. Using these strips, make three identical figures in the shape of a cross by taping two of the strips of paper at right angles at the middle of each strip. Make sure you tape the strips to each other on both sides and at both edges (you'll need four pieces of tape).
