We were learning about ' when vinegar and baking soda mix, an endothermic reaction occurs. This produces carbon dioxide which inflates the balloon. The endothermic chemical reaction will also lower the temperature in the area surrounding the vinegar and baking soda so significantly that you will be able to easily notice the change in temperature.
Next time I will ' When I try this experiment I will put more baking soda in a bottle and some more vinegar.
We were learning about what is action and reaction is and then we did balloon madness that links to action and reaction and for the balloon we had some string a bit of straw and a balloon. Then we got the piece of thee straw and thread throw the line and then got the balloon and taped it on to the straw. Ttheen we blowed up the balloon and let the balloon go and boosted up the line and then came down the line like a zip line.
I found it hard to make the balloon go up the string because we did't know how much air is in the balloon because we thought the a lot of air in the balloon would make it go high and a small amount of air would make it go slow and not long but the small amount of air go's longer.
I observed that so people had two balloon on the rocket and it made it worst because the balloon just spun around in a circle did nothing cool.
Next time I will try to balloon going up high and putting them in the right angle so they don't go bad and spun around.
What did you learn I learnt what is a I am poem is.
We were learning about what about self and then putting it on to the poem paper.
What did you learn I learnt that we should be prepared for a natural disaster because if a big disaster comes and hits you house it could turn bad.
We were learning about should we or should we not be prepared for natural disaster and why.
What will you do next time next time I should put more detail into my writing and writ less.
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).
What I learnt...I learnt that the hand washing liquid had a reaction to the milk with the food colouring and then made so magic in the milk.
What Happened
Oil stays above the water because the oil is lighter than the water or, more specifically, less dense than water. The oil and water do not mix because of something called “intermolecular polarity.” Molecular polarity basically means that water molecules are attracted to other water molecules. They get along fine, and can loosely bond together (drops.) This is similar to magnets that are attracted to each other. Oil molecules are attracted to other oil molecules, they get along fine as well. But the structures of the two molecules do not allow them to bond together.
What I learnt
When you added the tablet piece, it sank to the bottom and started dissolving and creating a gas. As the gas bubbles rose, they took some of the colored water with them. When the blob of water reached the top, the gas escaped and down went the water.
What happened
Observations and results
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.
What I learnt
We learnt that all of the alkaline acids mixed together makes the little explosion when it touches something wet like water and oil.
