WorksheetsMatter & Atoms
Total questions: 20
Worksheet time: 20mins
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
The point where a solid turns to a liquid is called the:
boiling point
melting point
flash point
Hulsey point
Nayeli decides to fry ice like the did in the Bill Nye video. As the solid ice melts into a liquid and then disappears as water vapor into the air, what is happening to the water molecule atoms?
They are losing electrons
They are forming new compounds
They are spreading out
They are separating into atoms
The density of carbon is 3.5 g, the melting point is 3,550 degrees C, and the boiling point is 4,827 degrees C. How does the density of a 5g sample of carbon compare to a 15 g sample?
The density of the 5g sample is 1/2 the density of the 15 g sample
The density of the 5g sample is the same as the 15g sample
The density of the 5g sample is double the 15g sample
The density of the 5g sample is triple the 15g sample
In the Bill Nye video, a kid "pour" CO2 gas into a bag on a balance scale and make the scale tip. Why can a gas be poured through the air?
It is less dense than the air
It is more dense than the air
It is cooler than the air
It is electrified
Two pieces of aluminum foil must have the same
mass
volume
weight
density
Jordyn throws limestone rocks at a tree. He notices that bigger rocks do more damage to the tree. Which properties do the rocks have in common since they are made of the same types of molecules?
shape and density
melting point and boiling point
solubility and volume
mass and weight
If a metal cube sinks to the bottom of a graduated cylinder filled with water, what has happened?
The solid is denser than the liquid
The liquid is denser than the solid
The mass of the liquid is bigger
The mass of the solid is bigger
A graduated cylinder measures:
mass
volume
weight
force ability
A triple-beam balance measures:
mass
volume
weight
gymnastics ability
Water has a density of 1g/cm. 4 substances and their densities are listed below. Which could sink in water?
oak- .6 g/cm
pine- .3 g/cm
poplar- .65 g/cm
PVC- 1.3 g/cm
