Using Models in Biology

Some concepts are tricky for students to visualise and become riddled with misconceptions. Getting some props out and building something for them to see, move and discuss really helps aid understanding and allows you to draw out any misconceptions. We have a great little box in the prep room of random bits to build models. Certain things are always useful; I always save the long cardboard tubes from wrapping paper as my go-to prop. Plasticine, pipe cleaners and a range of different sized balls or counters are also useful. Here are a few ideas:

Using a stool and tubes to represent vasoconstriction and vasodilation:

Kidney dialysis using Bunsen hose

Mitosis and Meiosis demonstrated using pipe cleaners:

I’ll add more as I think of them over the next few weeks but it’d be good to also hear other people’s idea…
