🧬Tracking My Learning🧬 || 🔬Genomics🔬

Last term we learnt about Genomics. Here are some of my information about genomics.

🧬Cheek cells🧬 || 🔬Genomics🔬

Today room 4 were taking a look at cheek cells. We wanted to see what our cheek cells looked like under a microscope. We are trying to see if we can spot some of the organelles we were learning about last term. The equipment we needed was a Popsicle stick, a slide, sodium chloride, and methylene blue (stain). We got into groups of 3 and I was in a group with Ayla and Makayla. One of us had to swab the Popsicle stick gently around the inside of their cheek. My group nominated Ayla to swab the Popsicle stick in her mouth. After she put her dead cells on the Popsicle stick she smeared the cells on the slide. We then put a tiny drop of sodium chloride on the slide where the dead cells were. After that step we put some methylene blue on top of the sodium chloride. We then went to lunch while the slide dried. After lunch we came into class and used the microscopes to see what the dead cells in our cheek look like. Aylas cheek cells just looked like little dots.
