Matter & Atoms

Matter is made up of atoms which:

• Can easily be seen

• have no weight

• have mass and volume

• don't take up any space

Why can't atoms be seen?

• They move too fast

• They are too dense

• They are hidden under the surface of the object

• They are too small

Shawn has 2 pieces of iron. Each sinks in water, has gotten rusty over time, and cannot be dissolved. Why do these 2 pieces of iron share the same properties?

• Because the atoms are different

• Because the atoms are the same

• Because they have the same physical properties but different visual properties

• Because they have different physical properties but the same rental properties

Rhianna looks at the Periodic Table of Elements and notices number 1 hydrogen (H), number 6 carbon(C), and number 106 Seaborgium (Sg). What do these names and letters represent?

• elements

• molecules

• compounds

• isotopes

Which of these lists are all made up of atoms

• steel, acrylic, helium

• carbon, oak, heat

• electricity, nylon, molecules

• iron, light, hydrogen

Which of these lists contain 1 thing that is matter?

• heat, light, the number 4

• electricity, gravity, compounds

• the color yellow, energy, dreams

• temperature, elevation, climate

What is the smallest bit of an element you can have that has all the properties of that element?

• a molecule

• a compound

• an element

• an atom

What are the common 3 states of matter? (Yes, this is a lie, there are 4. In fact, the 4th, plasma, is the most common thing found in our entire universe because all stars are made of it and the total mass of stars far outweighs the mass of other objects in space. Grrrrr.)

• solid, liquid, gas

• solid, gas, vapor

• liquid, solid, fire

• density, solubility, boiling point

Zach heats up water to make his favorite lunch, cup o' noodles. As the water heats up, what happens to the water molecule atoms?

• they expand and push against each other like balloons

• they gain mass and get bigger

• they move faster, spreading the heat around

• the molecule separates into the different atoms

What is needed to turn a solid into a liquid?

• heat/adding heat

• gas

• cold/taking heat away

• increasing the amount of the solid
