Snap! Crackle! Pop! [Rice KrispiesTM Treats Recipe]
Historians believe that marshmallows got their name when the Pharaoh of ancient Egypt discovered that part of the mallow plant grown in marshes could be made into a delicious confection. The recipe involves using margarine, marshmallows, Kellogg's Rice KrispiesTM and vegetable cooking spray. Melt it! Mix it! Spread it!

Math and Science in a Salad Bowl
Salads were poured out, and we made lists of their ingredients. The lists were used to arrange the vegetables into categories, such as the following:

Experimenting with Craters
Rocks of different sizes dropped from same height onto flat containers with 3-4" of flour coated with chocolate milk mix, for contrast. The sizes of the craters were compared with the sizes of the rocks. Also, the drop height [impact speed] can be varied.

Tornado Bottle [T], Coke [C]. and Bowling Balls [B]:
[T]: Take two 2-liter bottles; fill one with water; and then epoxy the caps together inside the right size/length of PVC pipe [inside diameter circa 1" or 25 -mm-, take the pop bottle to the hardware -tore with you to get the right size]; then turn upside down and shake around. Watch the tornado action. Bigger is Better: do it with 3 liter bottles, or even 5 gallon [plastic!] bottles, if you can get them.
[C]: Diet coke in cans floats and ordinary coke sinks. Why? [presumably, because of the extra weight of dissolved sugar]. Also, you can cheat by trapping air in the base indention, to make any pop/soda/cola can float!
[B]: The alien bowling ball [extra holes for all the fingers] sinks, whereas the ball with no holes floats --- and furthermore is unbalanced underwater. Explanations:
Stephen Fears [Eli Whitney Elementary School]
Mathematics with Straws and Tape
He reviewed these basic concepts: point, line, line segment, angle [acute, right, obtuse] . Then, we made the angles with straws and paper clips. We used three plastic straws and three paper clips to make a triangle. Using straws of several lengths, we made equilateral, isosceles, and scalene triangles. GeoboardTM lattices were used to create triangles and other figures using rubber bands. We then used a tape measure to measure our heights and our "wingspans", and found that they were fairly close to one another for most of us, except for a few "high-flying" individuals.
Marva Anyanwu [Green Elementary School] Her lesson was on the types of memory [short-term vs long term], and the categories: episodic [triggered by special events], autobiographical [self-conception], semantic [fact files], implicit [skills, such as singing or riding a bicycle]. General questions, such as
