 LI: To predict and test the buoyancy of an object.

Our task was to the predict and test out diffrent object's buoyancy. First we discuss why does something float, why does something sink and why does something semi sink.

The reason why objects is light and also it doesn't asborb H2O. The reason why somthing sink is heavy and no air. The reason for why does something semi float is heavy but has some air.

Then, we took notes of what is floating and sinking, we also talk about the Archimedes principle, the principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid.

After taking notes, we moved on to the experiment. The equipments that were used were:

• Marbles - both large and small

• Golf Ball

• Table tennis ball

• Tennis ball

• Different sized wooden blocks

• Different sized plastic blocks

• Polystyrene

We made a recording sheet that tells the buoyancy of each of the materials.

I really liked today's lesson because I got to learn why something, sink, and semi float and also I got to learn about Buoyancy and Buoyant.
