Particles
True or False: There are less particles when you push down on the plunger of a closed syringe than when you pull up on it.
False. If the syringe is closed the amount of particles stay the same.
Something that has definite shape and definite volume.
Solid
What are the 3 phases of matter?
Solid, Liquid, and Gas
What are bubbles made of?
Gas
True or False, this is Ms. Nakamura's first year teaching?
True! Ms. Nakamura has worked in schools before but was never the teacher.
Explain why air can NOT be in-between particles.
Air is matter, and matter can't be between particles. Air also has particles and particles can't be between particles.
Something that has no definite volume and no definite shape.
Gas
True or false, solid particles are perfectly still.
False. They can't move freely but they still are in constant motion.
What is matter?
Anything that has mass and occupies space.
What is Ms. Nakamura's favorite color?
Pink or any pastel colors.
How is air matter? Use evidence.
Air has mass. When we weighed a flat ball it increased when air was pumped into it.
Air also occupies space. When air was pumped into the ball, the ball expanded into a circle instead of staying flat.
What is liquid?
Something with no definite shape but has a definite volume.
Describe the particles in the 3 phases of matter.
Solid: Tightly bonded and can't move freely, but constantly shaking back and forth.
Liquid: Still bond together, but more loose and can move amongst their bond.
Gas: Completely free and constantly moving in straight lines.
How can you know if a chemical reaction occurred?
Bubbles/ fizzes, color change, temperature change, a new substance forms/ physical change of form or matter.
What is Ms. Nakamura's 2 favorite animals?
Sloths and Cats
Draw on the white board particles in a closed syringe when the plunger is still, when the plunger is pushed in, and when the plunger is pulled out.
Show on the board.
Explain the difference between compression and expansion.
Particles are closer together when compressed, and they are further apart when expanded.
How can we make the particles in a solid or liquid move faster or break apart from each other?
By adding heat.
What ALWAYS results from a chemical reaction?
A new substance.
How many siblings does Ms. Nakamura have?
2 older brothers.
Explain how particles inside a container is different from the particles outside the container.
The particles inside a container are closer together and bounce off each other more than the particles outside of the container.
What is equilibrium? Use an example.
It's when a system is stable or at the same place. Like when our plunger is moving back to it's original spot and stays there, the forces from the particles inside and outside are the same.
How did salt help our liquid ingredients turn into solid ice cream?
By adding salt to the ice cubes, the ice cubes draw in heat making everything around it colder. In this case our liquid ice cream ingredients.
How can we find out what is in a mystery mixture? (Think scientific method)
Purpose- What's in our mystery mixture
Research- Test out different substances and their reactions
Hypothesis- Come up with an education guess
Experiment- Test hypothesis and any other logical choices by mixing them, evaporation, and large scale demonstration.
Analysis- Record data and review it to figure out what was 100% for sure in the mixture
Result- Definitively say what was in the mixture and whether or not it was right or wrong.
Where does Ms. Nakamura live?
In Pinole.
