FORCES IN MATTER

Forces can act from a distance o through contact. When they act from a distance they are cold non-contact forces. When they come into contact with the object they are called contact forces.

NON-CONTACT FORCES

Magnetism is a force that can attract or repel mangetic objetcs. Let's watch the following video.

Gravity is a non-contact force that pulls objects towards  each other.

CONTACT FORCES

We have got  two different contact forces: Applied force and Buoyant force.

When an object is put in a liquid there is an upward force acting on it called buoyancy. This is what makes objects float.

Watch the following videos about this force:

PHYSICAL PROPERTIES OF MATTER

Matter is everything that exists. All living things and non-living things are made of matter.

Let's learn more things about Matter watching the following videos:

Forces Lab (Game)

Play this game!: In this lab you can do some actions that affects objects: squeeze, strech bend, slide, and twist. 

Magnets and Springs (Game)

Play with magnets to see how they can move objects. 

Gases around us (Game)

Solids and Liquids (Game)

When we heat or freeze liquids or solids some physical changes are produced. Play this game and learn. 

Reversible and Irreversible Changes (Game)

A mixture is something that contains two or more different materials. In some mixtures we can see the different materials; in other it is impossible to see the different materials. 

Play this game and learn about it. 

'Push and Pull' (Song)

Push and pull are forces. We pull things towards us and push them away from us to make them move. 
Listen to this song!.
