TODAY’S AGENDA
Green and Yellow Groups will stay at their desk and learn about atoms and elements
Blue and Red Groups will go to the back tables to work on their Element Superhero or Element Cube choice activity (this is due Friday!)

ATOMS
Atoms are the SMALLEST unit of matter, but what actually makes up the
atom???

SIZE OF THE NUCLEUS:
If an atom was the size of a football field
The nucleus would be the size of a nickel.

WHAT ELSE DO ATOMS MAKE UP???
Atoms also make up ELEMENTS.
What do you already know about elements?

ELEMENTS
Element : a pure substance made from
ONE type of atom. building blocks for all the
matter in the world. Examples : iron, oxygen,
hydrogen, gold, and helium. (Record at least two!)

ELEMENTS
The element gold is made up of gold atoms. All gold atoms are similar to other gold atoms because they have the same properties.
The element iron is made of iron atoms. Iron found on Earth is the same as iron found on Mars because they are both made of iron atoms!

ELEMENTS
Do you think iron atoms are the same as gold atoms?
Both are atoms, but iron are different from gold atoms, because
they are made of iron atoms.

ELEMENTS
There are over 100 different elements that make up all living and nonliving things!

INSIDE THE ELEMENT
The number of protons determines the atomic number in the periodic table of elements.
Example Hydrogen has a 1, so it has 1 proton.

INSIDE THE ELEMENT
The number below the symbol is the atomic mass. That is the mass of the protons and neutrons.

INSIDE THE ELEMENT
How are these two elements different??? What
do you notice?

INSIDE THE ELEMENT
How are these two elements different??? What
do you notice?
They have a different number of protons AND a
different atomic mass!

What is an atom?
Explain what makes the atoms of the element carbon different from the atoms of the element oxygen. Write complete sentences.
Explain what makes the atoms of the element carbon similar to the atoms of the element oxygen. Write complete sentences.
Define the terms mass and volume. Identify two objects with a different mass but similar volume.

What is the relationship between atoms and elements? One of these statements is false. Circle the false statement.
Then, write at least once complete sentence explaining why it is false. Most matter is made of atoms, but some matter is not. All carbon atoms are the same. Atoms are the smallest building blocks of matter. All matter has mass and volume.
How many elements make up living and nonliving things? Using the following words, record all examples of matter (hint:
