2. Core 3. Styrofoam and toothpicks because I think it is easiest do explain and I think it kind of shows people better. 4. Models are helpful because you can show people instead of just telling people and with showing it is easier for the people to understand what you are trying to explain. 5. I think that the reason that the Moon doesn't fall towards Earth is because the moon is in the Earths orbit and it just stays circling the Earth because the Earth weighs way more than the moon. So it has a better center of gravity. 6. Birds don't just fall because they weigh so little and there wings allow them to glide and they weigh so little that there wings pushing down is enough to keep them in the air. Planes stay in the air because they have a motor that pushes air out and makes them fly. 7.I think that some forces do cancel out gravity. I think that one thing that does cancel out gravity is helium. I know this because when you put helium in a balloon it floats up. I think it floats up because helium is lighter than air. 8. Learning about gravity is a good time to talk about craters because craters are from asteroids and asteroids fall to the ground because of gravity. |
