The Effect of Gravity on Speed

                           The Effect of Gravity on Speed   

        - Put the ramp against the seat of a chair.Place the ramp and chair so that the ramp points towards the hall way. 
-Place the ball bearing at the top of the ramp
-Lift the ramp 20 cm and release the ball bearing.
-Time how long it take to travel 5 m.
-Repeat the experiment 3 times for each height then do 40cm,60cm,80cm.


Height                          Time to travel 5 meters         Distance travelled
20                                  4.72 sec                                5m.90cm.
40                                   8.78sec                                5m 60cm

Effect of global warming


Image result for global warming effects 
-The earth getting hotter and the ice is melting
  especially at the Earth's pole.
-Sea level rise
-Flood 
-Less fresh water
Reduce global warming

          Parasitism is a relationship between two things in which one             of them (the parasite) benefits from or lives off of the other
the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control. 

Mutualismthe relation between two different species of organisms that are interdependent; each gains benefits from the other
Image result for commensalism

commensalism the relation between two different kinds of organisms when one receives benefits from the other without damaging it
