Our class has been going over the roar to Room 5 for Buddy time. My  buddy is Ted. Ted is the best buddy you could have. I enjoy buddy time because I love bonding with the juniors. My favourite part of buddy time is talking to Ted about things he has been doing.

My hypothesis

                                            My Hypothesis    

I think the heavier objects will fall faster than the lighter objects because heavier objects usually have more mass per surface than lighter objects.

Equipment:

Stopwatch

10 different objects

Towels

Pen and paper (to write down results)

Instructions:

1. Pick 10 different objects.

2. Compare their size and weight.

3. Find a suitable height to drop your objects from i.e.: top of a building/garage.

4. Have your stopwatch ready to time your objects.

5. Write down the outcomes of your objects.                                                                                                                                   

Planning A Fair Test:

The one factor I am going to change is the different type of objects .

The one factor I am going to keep the same is the height of the objects fall from.

In his own words, “I deduced that the forces which keep the planets in their orbs must be reciprocally as the squares of their distances from the centres about which they revolve.

Gravity is one of the four fundamental interactions of nature along with electromagnetism, and nuclear strong force and weak force. Modern physics describes gravity using the general theory of gravity.
