Question: We have to design a Physics lab that can be done on top of a mountain, any ideas?

Our whole grade is going up on a mountain and designing Lab Experiments in the science we are studying. I am studying physics therefore I have no other choice. We were told that on top of the mountains there was also a stream and a lake.
Uptil now I have studied:
Kinematics
Laws of Motion
Circular Motion and Gravitation
Work and Energy
LInear Momentum
Vibrations and Waves
Heat
Wave as Nature of Light

Answer: With the river and stream Kinematics, Laws of Motion, Gravitation, Work and energy all work… Also you could measure the change in the air Pressure from the ground and there…

!!MOLECULAR MOTION!! (WHOOOOOA)

Question: I’m looking for a chemistry experiment for homeschooling?

I would like to do the crystallization of minerals from a super-saturated liquid. But I just want to use household items or easily obtainable items, to show my kid the principal can be duplicated from the home. Any ideas?

Answer: Ben… depends to some extent on the level at which you’re trying to teach your kid. The idea of a mineral covers a lot of ground, so does the idea of crystallizing from a supersaturated solution. What exacltly are you trying to demostrate? Putting a piece of string into a cooling solution of sugar in a jar will result in formation of nice rock-candy crystals, and that demonstrates the idea of crystallization from a saturated solution. Demonstrating the phenomenon of crystallzation from a truly super-saturated solution means that you’ll probably have to get your hands on a chemical like sodium acetate (see, for example: http://quiz2.chem.arizona.edu/preproom/Demo%20Files/crystallization_from_solution.htm).

Hope some of that helps….

Crazy kids doing chemistry experiment

Question: What is something fun to do for a school science experiment?

Me and my friend need to think of an idea for a science experiment. Preferably something with food. We Can’t use any “living” things
(plants, bugs, rats, etc.) But don’t tell me what the result is.

also, nicole, that sounds fun, but i need something that has a variable, a hypothesis, and a question. (we aren’t doing this one) Ex- What diapers are more absorbent?

Answer: You should mix glue with borax powder (probably accesable from your science lab at school or whatever) and then you make something very cool!!!! You need to use PVA glue!!!

Measure 1/2 cup of warm water into the plastic cup and add a teaspoon of Borax powder to the water. Stir the solution – don’t worry if all of the powder dissolves. This Borax solution is the secret linking agent that causes the Elmer’s Glue molecules to turn into slime.

While stirring the glue in the mixing bowl, slowly add a little of the Borax solution. Immediately you’ll feel the long strands of molecules starting to connect. It’s time to abandoned the spoon and use your hands to do the serious mixing. Keep adding the Borax solution to the glue mixture untill you have a slime like material!!
