Week: 16
When we return we will finish our unit on Newton’s Three Laws and begin our chemistry unit. Hope your holidays are happy and safe.
Topic: Chemical Interactions: The Atom and its History
Students will be able to:
Explain why the atom is the building block of matter or maybe life.
Describe how atomic theory developed and changed.
Essential Question:
How did they find the atom?
This week the 8th graders had a short review on the structure of the atom and then went back in time to discover the atom. A small object (the atom) was placed in a small cereal box. They first had to locate the atom and then drop marbles into the box to determine the size, shape, movement, make-up, and any other discovery they made about the atom. Ask them about this fun little experiment.
