Reflection: Unit Planning How The Atom Was Proven To Exist - Section 1: NGSS Background


One of my favorite aspects of this lesson is the amount of ties that can be made to other subjects, something that NGSS is emphasizing with it's Cross-Cutting Concepts (CCC).

1) Social Studies/US History - the pollen that Robert Brown placed under a microscope is called Clarkia pulchella because it was first observed as a wildflower during the Lewis and Clark Expedition.
2) Math - Einstein brought probability into science by using it to make predictions of how the pollen grain would move based on its collision with a water molecule. The movement of the pollen grain's path was predicted with a high degree of accuracy.
3) LA - Einstein published his paper using Brownian Motion to confirm the existence of atoms in 1905. He had to argue, with evidence, their existence in a written journal article. The advancement of science depends on scientists writing clearly and succinctly.
4) Biology/Life Science - Einstein used pollen grains under a microscope to prove the existence of atoms.

How The Atom Was Proven To Exist

Unit 4: Atomic Structure
Lesson 2 of 5

Objective: Students will be able to explain how Einstein used Brownian Motion to finally prove scientifically that atoms exist.

Big Idea: In 1905, a young Albert Einstein published four groundbreaking theories. One of those theories used Brownian Motion to prove the existence of atoms. This lesson is part one of three describing how we discovered the atomic model used today.
