Snap! Crackle! Pop! [Rice Krispies^TM 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 Krispies^TM and vegetable cooking spray. Melt it! Mix it! Spread it!

Science observations and questions?

1. How do you cut 13" by 9" into 2" x 2" squares?
2. Change in viscosity with temperature?
3. Do air bubbles leave the marshmallow?
4. Why do some treats stick to plastic gloves, but not others?
5. Would treats cook faster in a glass dish?

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:

1. Roots: beets, carrots, radishes, sweet potatoes, turnips
2. Leaves: cabbage, da kale, lettuce, parsley, spinach
3. Seeds: beans, peas
4. Stems: onions, potatoes, sugar cane
5. Flowers/buds: asparagus, Brussels sprouts, cauliflower,

The Five Kingdoms of Living Organisms

• Animal: [many celled; nucleus] amphibians, birds, fish, insects, mammals, reptiles, worms, sponges
• Plantae: [many celled plants; nucleus] algae, conifers, ferns, flowering plants, moss
• Fungi: [absorbs food from surroundings; many cells; nucleus] mold, mushroom, yeast
• Protista: [one cell; nucleus] diatoms, euglenia, paramecia
• Monera: [one cell; no nucleus] bacteria, blue-green algae

• Martian Purple People Eater: [?] but be sure to watch out for them!

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:

1. bowling balls are made without holes, and the holes are put in for custom fit. The ball should be balanced [neutral orientation underwater] after the holes are cut; not before.
2. Bowling balls come in different weights, with the same size. The "sink point" is about 12.5 pounds; heavier ones float and lighter ones sink.

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. Geoboard^TM 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

1. Where in the mind are memories stored? [in non-localized form, in the cerebrum]
2. How much energy does the mind require? [70 watts; whether you are thinking, daydreaming, or "nothing"]
3. What is the role of dreaming while asleep? [consolidating; reprogramming].
4. How many different faces can you remember? [about 10,000]
5. How many different words can we remember [10,000].
6. Why are "hands on" exercises more memorable? [they are "memory hooks", apparently]
7. Can computers think? [***the answer to this question was deleted by the central processing unit on my PC; sorry about that ***].
