Monday, 8/24 Day 2 Science Starters Sheet 1. Please have these Items on your desk. Agenda 2- Fill out your Agenda. 3.Science Starter: States of Matter- One of four forms, Solid, Liquid, gas or plasma-in which matter exists. Liquid- A state of matter that has no definite shape but has a definite volume. Science notebook

Matter: It’s what the world is made of.

What is matter? Matter is anything that has mass and takes up space.

What do you know about matter? Solids Liquids Gases Plasma

Solids Solids have definite shape and definite volume. Solids have mass. Solids take up space. Objects don’t pass through easily. Read more!

Particles in Solids: Are packed tightly together Have very little energy Vibrate in place

Liquids Liquids take the shape of their container and have definite volume. Liquids have mass. Liquids take up space. Liquids have surface tension. Read more!

Particles in Liquids: Are loosely packed Have medium energy levels Particles flow around each other

Gases Gases spread out to fill the entire space given and do not have definite volume. Gases have mass. Gases take up space. Read more!

Particles in Gases: Move freely Have LOTS of energy

Plasma Lightning is a plasma. Used in fluorescent light bulbs and Neon lights. Plasma is a lot like a gas, but the particles are electrically charged. Plasma can flow like a liquid.

Particles in Plasma: Are electrically charged Have EXTREMELY high energy levels

STATES of matter? What would it take for matter to move from one state to another?

Energy determines the state!

Add or Subtract Energy... When energy is added, particles move faster! When energy is taken away, particles move slower!

What will happen? Why?

Solid + Energy = ? When energy is added to solids, they become liquids! Examples?

Liquid + Energy = ? When energy is added to liquids, they become gases! What examples can you think of?

Changing States There are several names for matter changing states: State change Phase change Physical change

So, did we get something new? Ice cream and melted ice cream? Chocolate and melted chocolate? Ice, water, and water vapor? Steel and molten steel?

Review Questions 1. What state of matter has definite volume and definite shape? 2. Describe the properties of liquids. 3. Describe the differences between gases and plasma. 4. What is needed for states of matter to change phase?
