Fizz, Foam And Froth

In class we have been learning about chemical reaction.

I enjoyed seeing it all bubbled up

I found it challenging to write how it happened.

Have you ever wondered what makes things fizz, foam and froth?

A physical change is reversible, like  how you can change ice back into water. A chemical change is irreversible. First, you put baking soda and a cup, then you add vinegar and it will explode. How did it happen? Well when you added the vinegar you changed the properties of the baking soda and that makes it explode.

Mix It Up

In  class we have been doing science experiment.

I enjoyed using the magnet to take out the iron filing.

I found it challenging to put the raro and sand into the filter paper.

this is what we did... 

Why do some ingredients seem to disappear when you mix them together? Why don't others? A mixture is a combination of two or more substances that cannot be chemically combined. If you put Iron filings with sand and raro you can get the iron filings out with a magnet.

If you add water to the raro and sand and pour it in a filter paper the sand will stay at the top. Then put the raro in the sun and the water will evaporate.

Gummy worms

  We have been learning about chemical reaction in class I found it hard to write the explanation.




  
Have you ever wondered what makes a polymer? A polymer is a long chain of hundreds or thousands of tiny molecules.To make a gummy worm  get calcium chloride with 2 cups of water this will be your activator solution  Then get a pipette and squeeze in some sodium alginate into the solution and now you have made your own gummy worms
