Topic 4 technology science

Today we went to technology.And today I am going to show you  my science work tnat I did at technology.

Why does something float?Because it to light to sink

Why does something sink?Because it is too heavy  to floor.

Why does something semi-floats?

Buoyant

bouyant 

Weight

Positively buoyant

Negative Buoyart 

Volume

Mass is how heavy its objects

Flood,Lights, Airless Disney, Less ,mass sink,heavier,denser,no air,Move mass,

Equipment:

-A variety  of balls

Table tennis ball

Tennis ball

Tennis ball

-serval blacks of material

Different sizes wooden blacks 

Different sizes   

Method (what to do):

-Set up a table to record information about each piece you test for buoyancy -as follows.
