What is matter?
Matter is anything that takes up space.
(Matter is NOT everything).
What is the first step of the scientific method?
1. Ask a question.
How can we find out more about matter?
We can use our five senses!
What happens when you put pressure on Oobleck? (When you squeeze it or push it?)
It turns into a solid!
What is a solid?
A solid is a type of matter. It does not change its shape. It does not flow. It does not compress easily.
What is the second step of the scientific method?
What are three different types of matter that we learned about in class? (states of matter)
Solid, liquid, gas.
What is a chemical reaction?
It is when two chemicals mix and make something new happen!
What is a liquid
A liquid is a type of matter. It changes its shape to match its container. It flows. It does not compress easily.
What is the third step of the scientific method?
3. Form a hypothesis.
What does all matter have in common?
It has weight.
(It has mass)
(It takes up space / has volume)
How do you make Gloop? (slime)
You mix a solution of water/glue with a solution of water/borax. The borax and the glue react to form slime.
What is a gas?
A gas is a type of matter. It expands to fit its container. It flows. It compresses easily.
What is the fourth step of the scientific method?
4. Test the hypothesis.
Why does an object float in water?
If something is less dense than water, it will float.
Why did the raisins float and sink in the carbonated water?
The carbon dioxide gas attached to the raisins (like floaties) and then the raisin/bubble became lighter (less dense) than the water and rose up. Then, the bubbles popped, releasing the gas, and the the raisin was more dense than the water so it sank.
What is a solution?
A solution is a liquid with something dissolved into it.
What is the fifth step of the scientific method?
How does matter change?
It can change from one state to another, like a liquid to a gas. It cannot be destroyed, only changed.
What is a non-Newtonian fluid?
A non-Newtonian fluid is a liquid that also behaves as a solid at times (like when its under pressure).
