What is DNA?:
You've certainly heard of DNA. Watch this video to learn more about it!
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!
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.
The button above takes you to Socrative. Once there, click on "student login" and type in the teacher room code: 519073.
Please sign in this way: Period space, Last name space, First initial. For example, if Mrs. McKeen was in my C period class and Mrs. Walden was in FG they'd sign in: C McKeen D FG Walden R
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.
Here is the first video for our review of Cells & Genetics and understanding the Coronavirus.
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.
Mitosis Music Video:
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!)
Fruit by the Foot:
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. Lights were placed on either side of the pot and switched on and off. 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!
Primitive Life Drops:
You were in class to see these, but your parents were not! Now they can see my amazing Life Drops!
Spider Chasing Laser:
A former student of mine shot this amazing video on the ceiling of her home. Does the spider think the laser dot is prey?
Meet the Stentor:
I photographed different Protozoa through a microscope. Dominating the scene is a horn-shaped stentor. It is one of the largest single-celled organisms.
How Bacteria "Talk":
At 5:00 mark, be sure to listen to amazing info about squid and bacteria.
Could Your Brain Be Hacked?:
This question sounds completely science fiction, doesn't it? Well, tell that to the mouse in this video...
Some Simple Life Sightings:
Here are some of the organisms we saw under the microscope in class during our Cells & Genetics unit.
Where Do Our Genes Come From?:
This video explain how many of our genes may have begun as mutations.
Pea Plant Maze:
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.
Parts of a Flower:
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.
Hard to believe bacteria can affect ice crystal formation, but it's true. Read on!
