Lesson overview
Lesson overview
In this lesson you will:
learn how atoms move and Brownian motion
review your understanding of the structure of atoms
examine the history of human understanding of atoms.
Intentions and criteria
Intentions and criteria
Learning intentions
To know that we can infer the presence of atoms by observing Brownian motion.
To understand how the model of the atom was developed over time and that the atom is composed of protons, neutrons and electrons.
To be able to complete an investigation and make observations of moving atoms.
To be able to research and clearly articulate a timeline of the development of the model of the atom.
Success criteria
I can use my investigative and observation skills to help me understand more about atoms.
I have successfully demonstrated comprehension and analysis skills to construct a table that highlights the timeline of the development and refinement model of the atom.

Challenges
Some of the activities in this lesson are must do activities. These are also called a mini challenge. Please have a go at the should do activities and reach out to your teacher if you need assistance. You could also spend some extra time problem solving a solution to these challenges. Finally, there are super challenge activities, the could do activities. We strongly encourage you to try these.

What Is Brownian Motion? | Properties of Matter | Chemistry | FuseSchool
Duration: 2:35
Note: When thinking about Brownian motion remember that BOTH liquids and gases are considered fluids.
Task 3 - Evidence of atoms
Task 3 - Evidence of atoms
In your exercise book or folder, write an explaination of how the experiment from Task 1 and the video from Task 2 supports the existence of atoms even though we cannot see them?
Task 4 - Brownian motion again
Task 4 - Brownian motion again
Watch this second video on Brownian motion. It is aimed at university level students.
As you watch complete the 3, 2, 1 activity template.

Task 1 - Structure of an atom
Task 1 - Structure of an atom
Draw a labelled diagram of an atom based on your memory and current understanding. There are no wrong answers here, so don't worry about getting it right.
Ask 2 of your friends or class mates, or someone at home to also draw a labelled diagram of an atom. Remind them that they don't need to get it right, the activity will be more fun if they don't try to be correct or look at what you did.
Get photos or screen shots of the three diagrams as image files that you can paste into a Google Slides.
Task 2 - Structure of an atom Venn diagram
Task 2 - Structure of an atom Venn diagram
Paste the three images into the Google Slides file.
Complete the Venn diagram to show the similarities and differences between the three diagrams.
If possible get together over video chat with the other people who shared their diagrams and try to come to a consensus on the important features to include in a diagram of an atom.

Activity 3 - The development of our model of the atom
Activity 3 - The development of our model of the atom
Humans have been thinking about atoms and trying to understand them for a long time. Our current model of the atom is based on 200 years of thinking.
Learning about this history and how our ideas have changed over time will help you understand the atom, and chemistry in general, better.
Task 1 - Timeline of the model of the atom
Task 1 - Timeline of the model of the atom

Handing in your work
Don't forget to hand in the work you completed today!
Your teacher will have told you to do one of the following:
Upload any digital documents you created and any photos you took of your written work to your Learning Management system (MS Teams, Google Classroom for example).
Email any digital documents you created and any photos you took of your written work to your teacher.
Make sure you keep any hand written work you did in your exercise book or folder as your teacher may need to see these when you are back in class.
