Germs & Microbes

Use experiments to teach science

What are microbes and can they be categorized as germs? How can we grow and study bacteria and fungi? How does infection pass from one to another and how can we determine where it began? How does our blood attack disease? Lab activities dig into these questions and are great for classrooms or homeschool.

Are Your Students Engaged?

Are you looking for a way to engage kids in their science learning? Are you eager to see your students become scientists in your classroom?

That's the goal of this course...

Activity Highlights

What's a germ? I think it depends who's defining it. Here we take a look at a wide variety of microbes and organisms to begin to see how they're classified.

Grow your own bacteria? Sure! Sounds like fun, ha ha. Detailed directions help you get through this activity with minimal fuss.

What's my blood type? We'll you'll have to test it. But before you do that you might want to try this experiment that uses fake blood and walks you through the process of blood typing.

How do we catch and transmit disease? Usually through human contact. Students LOVE this activity and beg to do it over and over.

Not all microbes are harmful. Show that to your students by culturing yogurt bacteria in the lab, then studying that same bacteria under a microscope.

Concepts and Topics Addressed in this Unit:

    ✦ Microbes are classified into Bacteria, Fungi, Algae, and Protozoa
    ✦ Viruses are not classified with living organisms
    ✦ Electron micrographs are often colorized to improve clarity.
    ✦ How can you count bacteria?
    ✦ How can you see bacteria without microscope?
    ✦ Where do bacteria live?
    ✦ Blood types can be determined using a set of 3 serums: Anti-A, Anti-B, Anti-Rh
    ✦ Each blood type shows a distinct clotting pattern with the three test serums
    ✦ There are eight distinct blood types: A+ A- B+ B- AB+ AB- O+ O-
    ✦ Phagocytosis is one method cells use to fight disease
    ✦ White blood cells are an important factor in fighting diseases
    ✦ Many diseases spread through contact
    ✦ Infections can be tracked through a community
    ✦ Unchecked, diseases spread exponentially
    ✦ How did people preserve excess milk before refrigeration?
    ✦ Are all bacteria harmful?
    ✦ What do bacteria look like under a microscope?

​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 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.

What if your kids 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 you don’t have time to introduce a lab?

No worries! if students work at at their own pace they can be independent and work through the instructions.The lab instructions are written directly to the students so you can just print and go.

When does the course start?

This course is a collection of lessons to use in your classroom. You can start as soon as you sign up!

Can I access these resources from my phone or tablet?

Sure! It works well on any device.​

Do I have to go in order?

Nope! You can use the lessons in any order—I always arrange them in a way I think makes sense, however since students in my classes worked at their own pace, they also tended to do the lessons in their preferred order. Within each section, the lessons progress from concrete to more abstract and from fundamental concepts to more tangential ones.

Who is this course for?

This course is designed for teachers to give them hands-on resources to teach middle school science.

Will this course work for homeschoolers?

I think so, though my background is classroom teaching. It’s not designed like a plug and play course. It’s a collection of activities that will help you teach the content.

What if I am unhappy with the course?

We would never want you to be unhappy! If you are unsatisfied with your purchase, contact us in the first 30 days and we will give you a full refund.

How long do I have access to the course?

After enrolling, you have unlimited access to this course - across any and all devices you own.

Meet the author...

Hi, I'm Carolyn Balch, the author of Engaging Science Labs. 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.
