1.2b Activity Complete Timeline of Atomic Models
What to achieve:
Use food and the A3 9 MG 1.2b Atomic Model Act Template M.docx provided to create a model of the atom developed by each scientist across time.
How to do it:
Democritus: Mintie wrapper, scissors. Cut the wrapper in half. Glue one half on the circle. Cut the second half in half. Glue one half on the circle. Keep going until you can't cut any further. Label this piece "atomos".
Dalton: 3 M&Ms of same colour. Spread the M&Ms across the circle and glue them.
Thomson: Choc chip cookie. Glue the cookie on the circle.
Bohr-Rutherford: Mini M&Ms three each of two colours. Place three of one colour in the centre and three of the second colour on the outside in two rings 2.1.
Bohr-Rutherford-Chadwick: Mini M&Ms - three each of three colours. Place three of two colours in the centre and three of the third colour on the outside in two rings 2.1.

Practical 1.3 Rutherford's Gold Foil Experiment Simulation
Practical 1.3 Rutherford's Gold Foil Experiment Simulation
Equipment:
Model = hula hoop is the gold atom (hula hoop is mostly empty space), styrofoam ball is the nucleus of the atom, hung inside the hula hoop using string and sticky tape. Then a ping pong ball (each?) to represent the alpha particles.
Procedure:
One or more students to collect data, someone to hold hoop. Other students have a ping pong ball (alpha particle) to launch at the model. A “miss” is when the ping pong ball goes straight through the hula hoop. A “hit” is when the ping pong ball hits the styrofoam ball (alpha particle hit the nucleus and bounces back). A “deflection” is when the ping pong ball hits the hula hoop and “makes a weird turn”
Results:
Construct a table with title Trial vs Outcome, and with column headings: Trial, Pass, Hit.
Enter a tally mark in the appropriate column for each outcome.
Evaluation (class discussion):
Rutherford’s Gold Foil Experiment had millions of alpha particles for his experiment, and we use ____ (each person gets 4 or 5 alpha particle launches) ping pong balls. Why would our data be different to Rutherford’s?
What are some good things about the model?
What are some ways it isn't accurate, reliable and/or valid?
Write sentences in response to the questions below.
Write sentences in response to the questions below.
Discussion: TSAR VIC
What Trends were observed?
What is the Science that explains it?
What are some ways the model is or isn't:
a) Accurate
b) Reliable
c) Valid?
How could the experiment model be Improved?
Conclusion:
Form a Conclusion by summarising the experimental results and discussion, then relating back to the aim.
1.2-1.3 Review
1.2-1.3 Review
The poem shows that while we might understand the parts of something, putting a model together from those might not give an entirely accurate picture. We are still learning and refining the model of the atom as new technology helps us to find new understandings.
