MATTER (slideshow and much more)

Hello, hello!!

These days we are talking about matter. Here you can see the slideshow we use in class. Ask any questions you have about it.

Pure substances and mixtures (HOMOGENEOUS AND HETEROGENEOUS)

We talked about mixtures, homogeneous and heterogeneous. And today we did one experiment about this. Here you have a video about mixtures:

Here you have some activities to review:

• Pure substance or mixture?
  
• Homogeneous mixture VS heterogeneous mixture
  
• Homogeneous mixture or heterogeneous mixture?

DENSITY

Density is a difficult concept understand at the beginning, so don't panic. If you have doubts, you can watch this video to see it clearly:

In this other video you can see the experiment we did yesterday:

Here you have some activities about density:

• Sink or float
  
• Float or sink

I found some more videos about dentisty:

 

  

Here you have some interactive activities you can do to review mass, volume and density:

• Density (compering objects' density)
  
• Mass, volume and density
  
• Mass, volume and density (2)

MATTER STAGES

Take a look at this slideshow I prepared for you:

Full fill this activity: MATTER _ STATE CHANGES (worksheet).

Here you have an interesting experiment about states of matter you can do at home:

PHYSICAL AND CHEMICAL CHANGES

Watch these videos about physical and chemical changes:

Here you have an interesting experiment about changing states of matter. Let me know if you do it at home:
