Making A Non-Newtonian Substance

• Making A Non-Newtonian Substance

Purpose: Our aim for this experiment is to see which state of matter oobleck is and to define the science
behind it.

Materials: Water, corn starch (or corn flour), bowl, spoon and a flat surface.

Steps:

1. Pour the amount of corn starch you want into the bowl.
2. Then obtain your water and put the water in the bowl.
3. Get your spoon and start stirring up your mixture.
4. You will start seeing the substance come together. As you start seeing the illusions, try getting the

perfect fusion.

Results: When we did the experiment, I saw the oobleck concluding together and clumping up to form.
It felt so weird because when I was holding the mixture tightly it was solid but when I let it go, it was
liquid. I was so surprised! The oobleck was so confusing and shocking.

Conclusion: Want to know the science behind all of this? The reason why this experiment worked is all
because of the two matters that are made out of particles, which are liquids and solids. In solids perspective,
the particles are very close to each other. The solid’s particles are very strong and their force is
unbreakable. But in liquids state, their particles are further apart from each other than solids particles,
due to the liquids weaker strength.

Cycle Of Making A Rainbow

• Cycle Of Making A Rainbow

Purpose: Have you ever wondered how a rainbow is made? Well today I will tricking your mind by showing
you a way you could see a rainbow.

Materials: You will need a glass bowl, water, white paper, medium-sized mirror and a flashlight/torch.

Steps: 1. Firstly, fill the glass bowl with water almost till the top. 2.  Then  place your mirror at the bottom
of the bowl, but if your mirror is too big - try placing it diagonally. 3. Get your long, white paper and hold
it straightly. 4. When you have completed all of the steps right, you will see something spectacular.

Results: While we were doing the experiment, I saw the colours on the paper converting into different
shapes as I would move the light. Shadows of the swirling water started appearing on the sheet. But
before the colours were visible, it took some tries to make it come onto the paper. Sometimes it changes
colours when the lights moves around. Here’s a tip, try keeping the flashlight/torch and paper still for
the best effect.

Conclusion: Want to know how a rainbow is made? Well basically… the sun pushes the white light in
the water. Since white light  is made out of 7 colours/the colours of the rainbow, the light rays help bend the
colours. Which soon makes the colours split in opposite directions and travel at different speed by water.
Then the rainbow starts to reflect back.

Recycling Water

Recycling Water

Have you ever knew that the water you drink, may have been drank by a stranger before? Well if you have
never noticed this circumstance, today is your lucky day since I will be telling you how water gets
recycled
and reused!

First, I will be telling you about EVAPORATION! You probably are asking yourself right now “What is
evaporation?” Well evaporation is when the sun soaks up the water from the sea,  river, puddle or lake.
The sun warms it up which makes the water rise up. Then the water vapour concluded together and it
transforms into a cloud.

Now, let's talk about CONDENSATION! It means when they water vapour in the cloud cools down and
reforms into water again. The water vapour gets so cold which makes the cloud lose lots of water.

The next step of the water cycle is… PRECIPITATION! This is when the water that cooled down, falls
down to turn into rain, snow, hail or either sleet.

Now, we are finally on the last step, which is COLLECTION! This part means the sea collects the things
consteinting of water. Afterward the water evaporates from the heat of the sun and it rises up. So then it
all starts again!

We use water, we drink water and we swim in it. Water is the number one thing a living thing needs.
We need water, so it would be good to learn about it. Next time you use water, think about this story and
wonder where it came from!
