This collection of hands-on activities digs into the concepts behind molecular motion including diffusion and osmosis. Students collect evidence of osmosis by weighting deshelled eggs and potatoes before and after exposing them to different concentrations of solvents. They’ll use two different models to explore what’s going on at the molecular level at different temperatures as well as during changes of state. All labs can be done qualitatively and many can be done quantitatively.

Are Your Students Engaged?
Are you looking for a way to engage middle schoolers in their science learning?
Are you eager to see your students become scientists in your classroom?
That's the goal of this course...
Invite students to become scientists in your classroom...
As fellow scientists, they need to learn to
investigate, discover, measure, observe, examine...
These skills take time and repetition.
But repetition can be boring!
That’s where labs come in!
Many of the labs are teaching the same fundamentals
but use different materials to keep things interesting.
What if my students are at different levels?
Ah, differentiation! In my classroom, everyone did the Core Labs (marked by Δ).
These are the labs we talk about in our discussions and they provide
the content for what we test. Extension Labs go deeper or broader
—some are tangents, and some repeat the core concepts for kids who need that.
What if I don’t have time to introduce a lab?
No worries! In my classroom, students worked at their own pace,
so I rarely introduced a lab. I write all of the instructions directly to
the students so you can just print and go.
What if I don’t have time to research the science behind a concept?
I’ve got you covered... Sections in the written instructions and the videos should
answer your questions. Here you’ll also find hints and helps for running an activity.
Additionally, the Teacher Notes sections will give you plenty of background information.
You won’t have to do any outside research unless you want to.
Each lesson has two parts...
1. Video instructions which include:
❑ a demonstration of the activity
❑ extensions for students who want to dig deeper
❑ hints and strategies for preparing each lesson
2. Written instructions which include:
❑ list of materials
❑ straight-forward directions
❑ questions and writing prompts
❑ explanations for the students and teacher
☆ straight-forward without being simplistic
☆ written to students; designed to be print-and-go.
☆ watch experiments; read directions; access background information.
Concepts and Topics Addressed:
♦ Investigating effect of temperature on diffusion
