Answer 1

You can make any simple machine having fulcrum, load and effort or u can even make a pulley.(These r very cheap and easy to make)

For ur project on universe u can get information from any encyclopedia or search in net.

Answer 2

take a card board of 150-200mm dia
on one side paste an image of a bird, say a parrot.
on the other side paste an image of a cage large enough
to hold the bird.
fix this card board on a stick.
if you twirl / rotate the stick fast enough i'e more than
10 rev. per second you will see / feel that the bird is
inside the cage.
better still would be to use charaka which is available in a khadi shop - to rotate the stick.
with bit of trial and error you will be able to get
over the alignment problem.
this this demonstrates persistence of vision.
wish good luck

Answer 3

OK, get a small postage scale, put a weight on it (Like a rock) and explain how gravity is an acceleration downward and how the scales springs reach equaliberim

A project on the universe? OK,, go to "astronomy picture of the day"- and work backwards for what you're looking for

Answer 4

drop a rock onto the floor and show newtons second law
