In Week 5, we looked at ingredients found in peanut butter cookies like flour, peanuts, sugar, salt, and egg(shell)s! Check out the recipes linked below.

Woohoo! Go biomed engineering!
Dr. Holly and Dr. Maude both represent the BME community well!
Sugar and salt look so similar looking at it with the human eye but under the scanning electron Microscope, they look very different!! That is soo cool!
It really is! SEMs rule!
This was a great presentation! I had a light microscope when I was younger as well. I remember always wanting to see objects through an electron microscope when I got older. Seeing the small properties of different objects is fascinating. At first I thought the image at the beginning of the show was flour, because of how circular the grains were. I also didn’t expect sugar to have a more lozenge-shaped structure compared to salt. Thank you for a wonderful stream!
It really is amazing how common ingredients all look like white powder to us, and how different they can look at the nano/micro-scale. Thank you for tuning in!
Hello. I am Jacob and I am 10 years old. I would love to see germs and skin cells under a microscope. I wanted you to put your finger under the microscope so I could see those things too!
Hello, Jacob! Thank you for tuning in to our show! We are so glad you could join. Maybe we can look at these in an upcoming episode. Skin cells/shedded skin will be easy to get but we have to be extra careful with germs so Dr. Holly doesn’t get herself or June the Science dog sick 🙂
Bravo! This is a perfect resource for science teachers!
Thank you! We’re glad it is useful. Thanks for watching!
