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: What happens to the rats after scientist are done using them for lab experiments?

Do the scientist release the rats in the sewers? Do they give the rats to the snakes? Do they dump the rats in the lake? Do they buried the rats and offer it a safe trip to heaven?

Answer: As far as i know those animals used for testing must be put down after the experiment.

After the experiment is done they are put to sleep in a quick humane way. This is good because if these animals did suffer during the experiment than they are not made to suffer for the rest of their lives. Also those scientific experiment that make animals suffer must go through a rigorous testing of their methods before the government allows them to take real animals.

So the answer to your question…they’re put down.

a.Electricity only goes through wires
b.Perhaps an electron doesn’t really exist
c.Perhaps a comet is like a moving electron

4 How could you prove the theory that atoms are like solar systems?

a.It is unlikely we will ever know for sure
b.By doing experiments and taking data
c.This is all a known fact already

5 In the Brownian motion, we observe directly the movement of

a.water molecules
b.capillary action
