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.

Science fair

For the past few weeks in class we have been doing the science fair.
I found it challenging to make the lava lamp.
I enjoyed working together.

Saint Bernadette

We have been learning about saints in class.
I enjoyed finding out about Saint Bernadette.
I found it challenging to fit everything in.

Here it is...


This year my parents took me on a trip to Europe and the UK.  On this trip we went to Lourdes in France.  That is where Saint Bernadette lived.  In 1858 she saw Mary 18 times when she was just 14.

Mary’s First Appearance

Bernadette was collecting firewood with her sister and friend when they went across the river.  Bernadette stayed as she thought it would be bad for her asthma.
She felt wind - but the trees weren’t moving.  She looked in the Grotto beside her and a beautiful young lady appeared before her dressed in white and with Rosary beads in her hand.  The young lady was Mary.

Bernadette was scared but the young lady smiled and without knowing what she was doing Bernadette took her rosary out of her pocket and started praying the Rosary.
Mary then took her own Rosary beads in her hands, made the sign of the cross and then moved the beads through her fingers as Bernadette said the Rosary. That was the first time Mary appeared to Bernadette.

What Mary Said

Mary asked Bernadette to pray for the sinners. She also asked Bernadette to get the priest to build a chapel where the grotto was. Mary encouraged Bernadette to pray the rosary.

Mary said to Bernadette”I can’t promise that I’ll make you happy in this world, but in the next…”
Miraculous Water
Bernadette dug out the spring water with her own hands after Mary told her to. Water from  the spring has healed people from all over the world. These are miracles.
We drank the Lourdes miraculous water and we washed our rosary beads in it as well.

Pilgrims

Many people from all over the world visit Lourdes as it is a holy place and some are sick and pray for a miracle.

Every night at Lourdes there is a candlelight procession for pilgrims. We went to this procession.  There is also an international Mass every morning that we went to.

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
