The Sodium Potassium Pump

I had always felt that there were limited resources on the sodium potassium pump. The Na+/K+ pump is an important little protein that is the pinnacle of “active transport”- though endocytosis and exocytosis are important cell functions, it’s also important for students to know that transport proteins may also require the use of ATP. Otherwise, students may falsely make the distinction that proteins= facilitated diffusion.  Sometimes if students do not understand something, they may dismiss it or form misconceptions.

The sodium potassium pump in particular needs to be presented in such a way that shows how it changes its shape and that it pumps 3 Na+ out and 2 K+ inside.  Typically, I’d show my students a video or two, talk about the sodium potassium pump a bit, and call it a day. However,  I didn’t have any valuable resources that the students could carry with them, so I decided to create a coloring and analysis activity:

Sodium Potassium Pump by Biology Roots

(This is available for purchase this here).

The coloring activity is great for such a visual concept.  The resource also contains an analysis page with 8-10 questions or fill-ins depending on which version- there are  three differentiated versions that are suitable for high school, middle school, or an advanced anatomy class (which need to know resting potential vs. action potential). I like having these handy because as you know your classes can change every year! You can find this resource in my store.

As I mentioned before, I’ve found resources for the sodium potassium pump to be pretty limited, but here are a couple to help  out:

Penn State Cell Transport– nice clear diagrams and written descriptions of all types of cell transport including the sodium potassium pump.

Khan Academy- The Sodium Potassium Pump (he goes into resting and action potential towards the end- also a couple of times he says  sodium instead of potassium- no judgement here- but, it might be a good idea to preview beforehand to make sure that his bloops won’t interfere with your kids’ learning styles).

Animation- how the sodium potassium pump works

I also offering coloring pages for endocytosis and exocytosis, passive transport, and hypertonic/hypotonic/isotonic environments.

What is your favorite resource for teaching cell transport?

Digital Resources for the Digital Age

If you have Google Classroom, you already know the benefits of going digital. To name a few:

  • Less paper
  • Less curse words in the copy room *wink wink*
  • Digital Interactive Notebooks do not require scissors, paper, or glue (which also means less MESS)!
  • Easier Grading
  • Students can keep track of their work (no more the dog ate my homework excuse!)
  • Easier organization at your fingertips
  • Digital resources can be used to supplement paper resources if you aren’t ready to go 100% digital!
  • Google offers a lot of time saving applications for teachers, like Google Quizzes.
  • You can add comments right in the document!

Here is a video preview of some ecology digital activities designed for Google Drive:

In Google Classroom, you can make a copy for each of your students to have. They can use digital notebooks on computer, Chrome books, or iPads. Give it a try and let me know what you think!

5 Helpful Tips for Teaching Genetics

5 Helpful Hints for Teaching Genetics

Here is #2 for my “5 Helpful Tips” series. If you missed the first one, check out 5 Helpful Tips for Teaching Photosynthesis.

Genetics is one of my favorite things to teach *cue sparkly harp music*. I really look forward to teaching genetics! And one thing that makes it so fun for me is discussing human genetics. Human genetics can be a bit mystifying, so I usually do not bring it up until we’ve discussed polygenic inheritance among other complex patterns, such as incomplete dominance. That is because most human traits are not Mendelian! For example, I have three children. Each one of my children has different colored eyes (hazel, brown, and blue).  Students love discussing this stuff and bringing up their own families, too!

Here is a complete list of human genetic myths that you can read for your consideration. But, that doesn’t stop us from making babies in biology class.  Besides, I firmly believe we still do not know everything there is to know, and we are making new discoveries every day. I tell my students that we are going to pretend that traits are Mendelian for a day so that we can do our fun Making Babies Heredity Simulation. I really feel that you need to find a happy medium here- I don’t want to teach students that human traits such as eye color and earwax are Mendelian, but I also want them to connect and have fun. So we do a pretend day each year. Besides, it gives them Punnett square practice and I honestly could not imagine teaching genetics without it! The kids have too much fun!

Visual learning is a lot of fun – I’m a visual learner and I use a lot of visuals when I teach. This website from Wiley’s Global Resources provides visual animations to help support Mendel’s ideas and laws.

I have found this web site invaluable for those who need extra practice or need an little extra oomph for grasping concepts in class.

Busting Student Misconceptions:

  • Students tend to struggle with some terminology- it can be really difficult for students to differentiate between terms such as DNA, gene, and allele.  Be sure to remind the students that there is in fact a difference, or maybe even ask them to compare them as a do-now, warm up, or bellringer. 
  • Are popular traits more dominant? No. You know this. Your colleagues know this. But sometimes we forget to mention this to our students. Check out my Exploring Human Traits Lab, in which students are asked to analyze this using your classroom as an example.
  • Epigenetics- students should know that environment can play a role in the characteristics of organisms. Epigenetics studies changes in heritable traits that are outside the human genome. Here is a quick video you can show your students about how epigenetic tags can be passed on:
  • Lastly, be sure to mention a few times along the way that mutations are not always harmful- and in fact some can be a good thing! The two examples I like to use are blue eyes (a neutral mutation) or even a turtle’s shell, which would be considered a positive mutation of its ancestor’s ribcage!

Veteran teachers, do you have any tips or advice when teaching genetics? I’d love for you to share them in the comments!
