Dalton’s Atomic Theory
Facts
Explain why you placed
these facts in this order.
What is your evidence?

5. Dalton’s Atomic
Theory
Atoms are tiny, invisible particles.
Atoms of different elements are different
Compounds are formed by combining atoms.
Atoms of one element are the same.

Cut out the atomic models and the words.
Match the model to the explanations.
DO NOT GLUE!

Timeline
Scientist Information Model
John
Dalton
1808
Matter is formed of small
pieces that could not be cut
into smaller parts called
“atomos” meaning
uncuttable.
10. Atomic Theory
Timeline
Scientist Information Model
Neils
Bohr
1913
Improved on Rutherford’s
model. He proposed that
electrons move around the
nucleus in specific layers, or
shells. Every atom has a
specific number of electron
shells.
13. Atomic TheoryChanges over time…
Because Scientific evidence gathered
from experiments gave scientists a
better understanding of atoms
14. Think-Pair-Share!
Take a minute to read the essential question as I
read it aloud: “How and why has the Atomic
Theory changed over time?”
After you have jotted down your notes in the space
on your guided notes, exchange your thoughts with
your partner. We will have share-outs and discuss
the answer.
21. Liquids
0 The particles in a liquid are close together but can
move and flow past one another.
0 Liquids have a definite volume but they do not have a
definite shape. This is why liquids like water take the
shape of the container they are in.

exact
moment these
water
balloons were
popped!
23. Gases
0 Particles in a gas have higher amounts of energy than
those in a solid or liquid.
0 Gases do not have a definite shape or volume. When
placed in a container, it fills up the entire container and
spreads out as far as possible.
26. In your groups, you will rotate clockwise after 4 minutes through the 5
stations. You will write all information on the Gallery Walk handout.
Stay with your group at all times.
Do not move ahead or go back, wait for the timer to move.
You may discuss possible answers with your group
members.
Raise your hand if you need assistance after you have
asked your group members.
