For many students, observing the microscopic world is an adventure they can take as part of their life science courses. But, in some … Read more

Student Models of Cells

There is a lot of value to having students make and design their own models during science class. The hands-on, kinesthetic approach incorporates physical movement, gives students the opportunity to make concrete connections with abstract concepts, and it allows students to express their knowledge in creative and often artistic ways. This is really important, particularly … Read more

Student-Led Cell Lessons

Middle school science is a time to build on the natural curiosity developed in elementary school while promoting science knowledge and expertise. It is part of our human nature to observe with awe and wonder the natural world around us. In middle school we get to foster that innate curiosity while pushing it to the … Read more

The Mechanics of the Lung Model

You probably noticed that pushing the large balloon in towards the smaller balloons caused the smaller balloons to deflate and flatten. Pulling it out caused the smaller balloons to inflate slightly. And, all of this occurred without ever blowing air into the straw… or so it seems! Before we get into the mechanics of the … Read more

Lung Model with Balloons

When you breathe, your lungs fill up with air, much like a balloon. But balloons require air to be pushed or blown into them. Does air get blown into your lungs like a balloon, or is something else at work in your respiratory system? The respiratory system consists of many different organs and muscles, including … Read more

Make Your Own Microscopes!

Did you know that you can turn your smartphone or tablet into a Microscope? Here’s How… Light allows us to see objects. It reflects off an object and projects an image onto the retina of our eyes, which our brain then interprets. But, if we bend the light, we can change how the object projects. … Read more
