States Of Matter
States Of Matter
Purpose: Did you know that oobleck is non-newtonian? This means that it does
not follow the rules of the three states of matter. Today, we are going to find out
which state of matter oobleck is.
Materials: Cornstarch, water, bowl, spoon and a flat surface.
Steps:
1. Get your cornstarch and place it on your flat surface or your bowl if you want.
2. Then, put in some water to make it like dough. Don’t put too much or it will
become liquidy and put enough in because if you don’t, it will become hard.
3. Watch what happens to the oobleck when you put lots of pressure on it and
watch when you press on it very softly/lightly.
Results: I noticed that when we put lots of pressure on it, it becomes solid and
when we put it down very softly, it becomes liquid.
Conclusion: The three states of matter are liquid, solid and gas. They are all
made out of little particle. In solid state, the particles are very close to each other.
The particles hold each other very tightly. Solids have a shape and a volume too.
In liquid state, the particles are also very close to each other but are farther apart.
Liquids have a volume but not a shape. The last state of matter is gas. Gas are
very far apart from each other and their force is very weak. Gas does not have a
definite volume nor a shape.

Public Or Private?
Today, our cybersmart teacher came in and asked us to write our personal information that we would share online and and the personal information that we would not share online. Here is my work that I have created.
This screenshot is the right answers. I thought and still think that you could share your brothers and sisters name because why could you put your name in and not theirs? And I forgot to put the email address in the information that you couldn't share.

Rainbow Experiment
Rainbow Experiment
Purpose: We are trying to make a rainbow and find out what happens when we shine the light on a mirror with water inside of a glass bowl.
Materials: Water, mirror, 1 glass bowl, and a white piece of paper or book.
Steps:
1. Fill your glass bowl with water until it is almost full.
2. Then, grab your mirror and put the point/corner at the bottom of the bowl.
3. Grab your flashlight or torch and shine it on the mirror.
4. Try and move your flashlight or mirror because it will never appear on your first try.
5. You will see a rainbow on your paper or book if you put it in front of the mirror.
Results. I noticed that we never get the rainbow immediately because we have to move the flashlight and mirror around so the rainbow can appear on the book.
Conclusion: Do you wonder how this experiment works? Well, let me explain. The white light from the flashlight goes through the water and m splits into 7 different colors, (red, orange, yellow, green, blue, indigo and violet. Then, the mirror reflects it back onto the book.

Fire Vs Water
Fire Vs Water
Purpose / Question: Find out what happens to a lit up candle when you put it on top of a bowl of water and when we push it down to the bottom of the bowl with a clear glass.
Materials: 1 tealight candle, water, 1 lighter, an adult, a clear bowl and a clear glass.
Hypothesis: I thought that the tealight candle was going to float.
Steps:
1. Grab your clear bowl and fill it up halfway with water.
2. Light up your tealight candle with a lighter.
3. Gently put it on top of the bowl of water and find out what happens.
4. Then, grab your clear glass and push it down to the bottom with the candle inside and see what happens.
Results: I noticed that the glass became steamy and bubbles appeard when we pushes the glass down to the bottom.
Conclusion: The reason why the candle didn’t go out but only after about seven second was because, when you push the down with the glass, all the air inside it pushes all the water out of the way so when there is no water left inside the cup. The reason that the flame went out after around seven seconds was because that the flame used up all the oxygen in the glass.

Manaiakalani Survey
Today, Mrs Collin came into Room 10 and helped us do a servey about our learning.
Some of the questions were very difficult and tricky but most of them were pretty
easy to answer. I really liked when they asked us questions and we had to choose
between 1 to 5.
