Question: How can I design a better Science Experiment For Preschoolers dealing with flour?

We are going to read a book about cupcakes and then for science I’d like to do an experiment with flour. Without actually cooking anything. Is letting them play with the flour and then mixing in water to see the change enough? Is there anything I can add to it?

Answer: You can make non cooked play dough. It will require mixing but at least you don’t have to cook it on a stove.

Here is a recipe I found

NO – COOK PLAY DOUGH

1 c. water
3 c. flour
1 1/2 c. salt
1/4 c. oil
Food coloring

Combine ingredients in bowl and mix. Add more flour if mixture is too sticky. Store in a plastic zip-lock bag.

Question: Should I eat a box of 12 fresh hot glazed Krispy Kreme donuts in the name of science?

I have been so good this holiday about eating healthy and avoiding snacks. BUT, I have been craving fresh hot glazed donuts from Krispy Kreme for weeks now. I have even dreamed of them. I know it sounds silly, but I just HAVE to have one or more.

The Proposed Experiment:
I think I could possibly consume 6 in one sitting , but don’t know if I can eat 12. Should I see if it is humanly possible for me to eat 12?
Should I stop at satifaction, or pig out and get it out of my system? OR, should I keep on avoiding them though they call out to my inner being?

You may answer as you wish, no offence will be taken. Please use child friendly vocabulary. (No ugly words please)
Uh, yeah 20 is far too ambitious. I dont want to vomit.
I will let you folks know the outcome. Ya know, for Science and all!

Answer: OMG! I love Krispy Kreme donuts. I swear there’s got to be crack in them or something, they’re so addictive. I’ve had about 3 or 4 in one sitting but 12? Honey, you’re tummy is gonna be hurting! And to think of all that sugar in your body at once, surely you’ll get sick to your stomach. But if I were you, I’d go ahead and indulge a little. I mean damn, you’ve been dreaming about these donuts you might as well, right?

Question: Does anyone have good Science Fair Ideas that involve astronomy?

Something that is appropriate for 11-13 year old kids. Please nothing that requires a specific weather to do it in. IT MUST BE AN EXPERIMENT!

Answer: Unlike the other natural sciences (e.g. chemistry, biology, genetics, etc.) Astronomers can not manipulate their subjects, so all of our experiments must be conducted through observational studies.

Now, here’s what I had in mind for and experiment. You can demonstrate how local space can be curved by large gravitational bodies. Take a net say like nylon stockings cut them up one end and stretch them tightly against a square form. So, you wind up with a square covered over by nylon stockings. Carefully paint (or draw an equilateral triangle in the square. Document each angle as measuring 60 degrees. Then take a softball or soccer ball and place it in the square. Now with a protractor measure the angles of the triangle. They will no longer be 60 degrees. The total degrees int the triangle will be not be 180 degrees. Obviously, the mass of the ball is warping the fabric causing it to stretch. The very same thing happens with large gravitational fields, they warp the fabric of space and time.

You can correlate your experiment to the one conducted in 1919 to prove this theory.

Or you could build a focault knife edge tester to demonstrate how deformations in mirror surface can be detected by the human eye up to 1 billionth of an inch. You can do this very easily with a low light incandescent bulb, and makeup Mirror (convex) and a straight edged razor blade.

I know those all sound off the wall but without going outside to observe you’re up against a wall.
