Biology

We are finally starting our 🩸 BLOOD EVIDENCE 🩸 unit over in Forensics and we kicked it off with a lesson over blood typing.

After teaching about serology and blood typing, I had my students try their hand at a little murder mystery lab that I call DUMPING GROUND. ⚰️

This lab is so easy to set up and only uses household chemicals!

My new favorite classroom hack- use a straw dispenser to hold classroom pencils ✏️ ...

I’m starting my cell transport lesson with this fun 🫧 CELL MEMBRANE BUBBLE LAB 🫧

In this lab, students perform 4 tasks that model properties of the cell membrane.

This lab is so easy to set up and is always a student favorite.

To kick off our cells unit, my Bio students participated in a CELL ORGANELLES SPEED DATING ACTIVITY!

Students were assigned an organelle to research and created a dating profile. Then, they “dated” each other to learn more about the different organelles that are found in cells.

I served punch and put tea light candles in the desk. @maniacsinthemiddle came in clutch with her ❤️ love-themed playlist on Spotify (search Miss Bensko to find it).

It was the best day! 🤩

Most of my bio students come to me with no understanding of chemical reactions. (Our students take Bio before Physical Science or Chem.)

I find that it’s really difficult to teach “Chemistry of Life” if students don’t understand basic Chem.

I decided that I would do the elephant toothpaste demo so that when I’m teaching about Chem Rxns, students will have something to help them visualize the process.

I always love this demo. It makes me want to teach Physical Science again.

Here’s the recipe that most groups used:

To get a good reaction…

50 mL 30% Hydrogen peroxide
5-10 mL dish detergent
20 mL Potassium iodide solution (1M)
a few drops of food coloring

The best reaction was in a 1000 mL flask

*Note: the last group in the video doubled their recipe! 😉

Last week, my forensics students learned about @the_innocence_project. They researched people that had been exonerated through TIP and created a banner to showcase their work. I love how they turned out!

Another day…. another lab 🥼

Today in Biology, students tested their knowledge of macromolecules with this engaging Macromolecules Murder Mystery 🕵️‍♀️
