Teaching cell structure and function is probably one of my favorite topics. There is just something magical about introducing students to the microscopic world of cells.
Cell structure and function also form the foundation of most of the biology curriculum, so I prefer to teach it right at the start of the school year. I will constantly refer back to this section of work throughout the year, reinforcing concepts and identifying misconceptions.
Over the years I’ve identified some tips and ideas for effectively teaching about cell structure.
1. Start with the basics
I always start with a very basic introduction to cells. We’ve all used the analogy of cells being like a big city with different buildings, factories, roads, etc. that each has a specific function. I’ve recently seen a great scavenger hunt activity posted on Instagram. It’s always a good idea to get your students moving!
2. Microscope Magic!
Using a microscope for the first time is a highlight for many students. That “WOW” moment when they first see a cell is just amazing.
I always spend some time on basic microscope skills. Students need to realize that it is an expensive piece of equipment and that rules need to be followed. My students are very aware of the fact that using a microscope is a privilege and not a right.
Once they have practised focussing the microscope with some prepared slides, it’s time to make their own. Slides of onion skill cells are easy to prepare and stain and students love it. Your classroom may smell like onions for a while, but it’s worth it!
This is also a great time to introduce drawing skills in biology. You can read more in this blog post.
3. Let’s get creative!
Students always love building models of cells. Personally, I’m not a big fan of using food to create models. Unless it will be eaten, it’s a no-go for me. Students are creative creatures and they usually come up with some amazing models. I’ve even seen a crochet model!
4. A variety of activities
When teaching cell structure, I try to give students a variety of activities to do. My students love a good color-by-number! Review before a test? Boom Cards are always a hit. And honestly, there is nothing wrong with a good old cut-and-paste activity!
5. Going digital
There are loads of great videos out there to help you with this topic. Amoeba Sisters is a firm favorite of mine for Middle School classes or even as a quick review for some of my High School groups. For more advanced groups I prefer to use the videos from Crash Course.
I hope you found some ideas to incorporate into your lesson.
Happy teaching!
