There is an easy equation to use for formation questions, but in combustion I get confused. How do you construct the energy cycles? Thanks!

Ahmad and Bob want to calculate the height of a tree. They measure the angles of elevation to the top of the tree. The angle of elevation from Bob, who is standing 60 m from the base of the tree, to the top of the tree, is 40˚. The angle of elevation from Ahmad, who is standing 80 m from Bob, is 50˚. The height of the tree is 50 m. Calculate the angle between Ahmad and Bob.

i have to do a project for science and part of the project is to think of a lab idea. the hard part is the lab idea has to be based on earth science (meterology,astronomy,oceanogr... or geology) the lab idea has to be unique and it can't be a lab that is able to be done in 2 days. (the longer your lab and the more effort you put into it the better your grade)

Can you please help me come up with a real good lab idea your help is highly appreciated.

P.S. make the lab easy enough for a 9 grade student to do.THANK YOU SOO MUCH
