Free Lunches In Schools Are A Fantastic Thing For Students

We were learning about persuasive writing and it is a type of argument writing🍎

I found it easy to publish it onto a google slide and put onto my blog🍓

I found it hard to write it on a google doc🍒 

next time i will make it longer🍉   

Milk Colour Explosion!

in today's science elective we were learning about milk and when you put food colouring and soup into it and this is what happened... Milk is mostly water, but it also contains vitamins, minerals, proteins, and tiny droplets of fat suspended in solution. Fats and proteins are sensitive to changes in the surrounding solution (the milk).

The secret of the bursting colors is in the chemistry of that tiny drop of soap. Like other oils, milk fat is a non-polar molecule and that means it doesn’t dissolve in water. When soap is mixed in, however, the non-polar (hydrophobic) portion of micelles (molecular soap structures in solution) break up and collect the non-polar fat molecules. Then the polar surface of the micelle (hydrophilic) connects to a polar water molecule with the fat held inside the soap micelle. Thanks to the soap connection, literally, the non-polar fat can then be carried by the polar water. This is when the fun begins.

The molecules of fat bend, roll, twist, and contort in all directions as the soap molecules race around to join up with the fat molecules. During all of this fat molecule gymnastics, the food coloring molecules are bumped and shoved everywhere, providing an easy way to observe all the invisible activity. As the soap becomes evenly mixed with the milk, the action slows down and eventually stops. This is why milk with a higher fat content produces a better explosion of color—there’s just more fat to combine with all of those soap molecules.

Cold Air Ballon

 We were learning about Cold Air Ballon

I observed how the Balloon filled up with air from the baking soda and vinegar mix.

Next I will blow it up!

    

Balloon Madness

 We were learning about endothermic reactions and Newton's 3 Laws of Motion.

I observed how the balloon travelled along the piece of string.

Next time i will try this at home.  

Barth Bomb

 In today's science elective we were learning to make Barth Bombs.
When a bath bomb comes in contact with water, the baking soda and citric acid react to make carbon dioxide bubbles. This is an acid–base reaction, where baking soda (also called sodium bicarbonate) is a weak base and citric acid is a weak acid.  

Lava Lamp

During Science elective today we were learning to make homemade Lava Lamps and what the reaction was. What happened was that the oil stays above the water because the oil is lighter than the water or more specifically, less denser then water. The oil and water do not mix because of something called "intermolecular polarity."  

  
      

   

     

It is important to be prepared in a natural disaster

 We were learning about persuasive writing and it is a type of a opinion writing.

I found it easy to put it onto a google slide and publish it.

I found it hard to write it on a google doc.

Next time i will add more ideas.
