Fair testing
A fair test is when all conditions are exactly the same for both tests.
Things we used for tests ...
-Blue shot put
-Green shot put
-Red petanque ball
-Green hockey ball
-Brown hockey ball
-Tennis ball
-Green petanque ball
-Sponge
-Foam softball
In all fair tests, the objects landed at the same time. This means that the force of gravity IS constant. All objects fall at the same rate!!!!
That is what we learned about gravity yesterday ... so we'll post some more tomorrow.
