Mr. Gonzalez's Science Classes
We have three 6th grade Science classes and two 8th grade Science classes blogging here from the Pacific Northwest in Chimacum, WA! Sixth graders are learning a bit about Mt Saint Helens, environmental science through fresh water ecology, and physical science this year. Eighth graders are learning about life science this year. Please join us as we learn Science by exploring our world.

1. The growing part of the mitosis is the longest period of all. During the cell cycle the DNA duplicates and divided, and the proteins are being produced. The cells will also be growing in size.This is the first step which is called the interphase.
2. During the interphase the cells are starting to divide which then splits into to 2 sister cells during this stage the proteins are being made.
3. To produce the 2 sister cells the DNA instructions in the cell MUST be duplicated. This situation occured in the synthesis phrase. The chromosome splits into two identical chromosomes.The cells mother give the daughter cells all they need to survive.
The cells are able to split into 2 cells and are the same exact cells due to the chromosome makes the EXACT duplicates of themself.
Interphase: the longest and the busiest period of the stage. The DNA duplicates and the cells are dividing.
Prophase: In this stage the nucleolus starts to fades. The nucleolus then strats to meet together into chromosomes.
Prometaphase: This stage is where the nucleolus envelopes break down. This stage is where the proteins are being mixed together and where the 2 sister cells are at.
Metaphase: Tension applied by the spindle fibers aligns all chromosomes in one plane at the center of the cell.
Anaphase: The spindles fibers are shorten and the 2 daughter cells are being torn apart. they then later travel towards the cell pole.
Telophase: The daughter cells arrive at the cell pole and the spindle fibers that pulled the sister cells apart dissappeared.
Cytokinesis: The spindle fibers begin to break down. Contactile ring cleaves the cell into 2 daughter cells. Then the new cytoskeleton are being reorgonize bu the microtubules and then they are later return to the interphase stage of the the Cell Cycle.

I started my teaching career in South Central Los Angeles teaching in modified to full bilingual 4th and 5th grade classes. Then I moved to WA State where I have taught mainly 6th through 8th grade. I have enjoyed the culture clash but notice that kids are the same everywhere :o)
My areas of interest are science and technology but I also love studying ancient cultures and learning about different peoples and cultures.
