Hard to believe bacteria can affect ice crystal formation, but it's true. Read on!
You've certainly heard of DNA. Watch this video to learn more about it!
Dark skin and blond hair? Diet? Exposure to sunlight? Mixing with "outsiders"?? None of the above. Watch!
We have a poster of this kind of cell division, but here's a video!
This video shows chloroplasts from an elodea leaf very clearly.
Here's the video that explains the Genetic Wheel activity. Discover if you are a mutant!
Mrs. Papen and I show you how you can extract DNA from a banana!
Mr. Neil Ganem at BU digitally colored his photograph of a cancer cell going through mitosis. We thank Mr. Ganem for sharing this with us!
This animated video from TED Ed is
at a middle school level.
This video goes into more details than my students are responsible for, but it does a good job of explaining how chromosomes copy and divide. (Catchy song, too!)
Two kids replace one thing and then another with "Fruit By the Foot". The game is won when one kid replaces his friend's DNA with Fruit By the Foot. Why?
Time lapse capture of peas growing. A light was placed on one side of the pot and switched about every 12 hours. The experiment was to see if the seedlings grew toward the light.
This simple animation shows how organisms grow from one cell to two, four etc.
Move slider at bottom of page to see relative size of objects. Amazing!
You were in class to see these, but your parents were not! Now they can see my amazing Life Drops!
A former student of mine shot this amazing video on the ceiling of her home. Does the spider think the laser dot is prey?
I photographed different Protozoa through a microscope. Dominating the scene is a horn-shaped stentor. It is one of the largest single-celled organisms.
At 5:00 mark, be sure to listen to amazing info about squid and bacteria.
This question sounds completely science fiction, doesn't it? Well, tell that to the mouse in this video...
Here are some of the organisms we saw under the microscope in class during our Cells & Genetics unit.
This video explain how many of our genes may have begun as mutations.
I placed a pea plant in a special box where light entered only from one hole in the top. Horizontal shelves forced the plant to zig zag around them on its way to the light at the top.
This video helps students understand the reproduction of flowering plants. It was through Gregor Mendel's work with pea plants that the basics of genetics was discovered.
The Cells & Genetics Socrative Quiz is now open! I suggest you wait until around November 6 to try it for the first time.
The button above takes you to Socrative. Once there, click on "student login" and type in the teacher room code: 519073.
Cork as it Relates to Cells
The term "cell" as in "the building block of all organisms" goes back to the seventeenth century. This presentation traces the history of this term.
The button above takes you to my Google Drive where I've shared the unit activity sheets. Read through them on-line so you can work through more in class.
