Diffusion, Osmosis and the Cell

Use Experiments to Teach Osmosis, Diffusion, and the Cell

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...

And these skills take time and repetition.

But repeating stuff 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 you 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.

I started my career as a high school physics teacher. Then I entered the field of museum education at the National Air and Space Museum (part of the Smithsonian Institution) where I wrote science education materials and ran teacher workshops. When my children were born, I left the workforce and when they were little, our family got involved with a school start up. My children grew and with them, the school; I volunteered on a weekly basis, running science experiments for my son's class and joined the faculty as the middle school science teacher when the seventh grade was added. Now I write full-time, working to publish the curriculum I developed while I was teaching. Each online course is a unit of study from a hands-on, laboratory-experience perspective. Each activity has a video and written instructions so you'll be thoroughly prepared to teach them.
