Food Bank Wrist Bands!

Mr. Forde's advisory has been selling orange wrist bands (see above) for $1 to support the Food Bank of Lower Fairfield County. We would like to thank all of the students and staff who supported us. We are ready to donate over $250 to help the needy in our own part of Connecticut!

Thanks so much for caring!

Mr. Forde and advisory!

What is Meiosis?

Hi All!

We have learned about mitosis. Now what in the world is MEiosis?

For a preview click on the following link.

Mitosis vs. Meiosis

At the end of Meiosis cell have only half as many chromosomes as a normal body cell. Why would it want only half the number of chromosomes?

enrichment post - #7 -Build DNA!

source- biology

Hi All,

From a focus on cells to a focus on the genetic material within the cell that makes us who we are!

Fo fun try the link below and select the building DNA activity. This will teach you more about the structure of the DNA molecule.

Build DNA

You may try the others also, but they may be a bit complicated until we cover the concepts in class.

All the best and see you soon!

The mitosis song!

The words to the Mitosis song!

(sung to the tune of “London Bridges Falling Down”)

In mitosis cells divide, cells divide, cells divide,
In mitosis cells divide,
For cell reproduction.

In interphase chromosomes duplicate, duplicate, duplicate,
In interphase chromosomes duplicate,
For mitosis.

In prophase we now see chromosomes, see chromosomes,
see chromosomes,
In prophase we now see chromosomes,
In mitosis.

In metaphase chromosomes all pair up, all pair up,
all pair up,
In metaphase chromosomes all pair up,
In mitosis.

In anaphase chromosomes move apart, move apart,
move apart,
In anaphase chromosomes move apart,
In mitosis.

In telophase there are two new cells, two new cells,
two new cells,
In telophase there are two new cells,
In mitosis.

Mitosis Quiz tomorrow

Hi Bloggers!

The quiz tomorrow is on the stages of mitosis. You will be shown cells in various stages and you are to guess if there are in Interphase, prophase, metaphase, anaphase or telophase.

For example, what phase do you think this cell is in?

If you said, Metaphase (because the chromosomes are lined up) then you were correct!

Good Luck,

Mr. Forde :-)
