Float and Sink:
For this lesson, I have created 6 objects; glass, ice, gold, stone, steel and rubber. Out of these, I predict that the rubber and ice will float on the surface of the water, the glass will float in the water, and the gold, stone and steel will sink to the bottom.
Each ball has different properties. in the context of this lesson, the property that matter is the density, the kg/m2.
Some objects float while others sink because of their density. the objects with density more dense then water will sink, while the objects that are less dense will float.
When the objects are put in the water, they will transfer it their kinetic energy, thus moving it around, then float or sink to where their density allows.
I expect the majority of the iceberg to be pushed underwater by its weight, but for the tip to float due to its density.
When the iceberg melts or pieces fall off, it will float closer to the surface. This is because its weight will lower, thus putting less pressure on the water and allowing the water to push it up higher. The pieces that break off will be (relatively) light, and will float the the top.
If you turn the iceberg into water, the iceberg that was slightly above the water level will level out, and the water level will be slightly higher then before.
The iceberg floats because its density is lower then the density of the water.
When the icebergs shape is changed, the water pressure around it will keep the ice cut off trapped against the iceberg.
When the iceberg melts, the water level raised slightly as the ice above the surface flattened out.
Friction and Surfaces:
I think that there will be a difference on how the object picks up speed because of how much friction each box has.
When the plane of each slop is increased, the object slides faster and farther; when it is decreased, it slides a shorter distance and slower.
The speed and distance is different for each plane, because each plane has a different amount of friction.
