My time at odyssey(:


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.

Meiosis and mitosis!!!

Article posted January 31, 2012 at 08:15 PM GMT • comment • Reads 806

Meiosis and mitosis are kind of alike ways they are alike is both of them create cells, but the difference is that mitosis makes two cells and meiosis only make four cells. Both of them pass on DNA to the cells they have made. The meiosis cells have different DNA but the mitosis made cells have the same DNA. That is differences of the two.



The steps of dividing/multipling are:

Interphase: They DNA copies each other then the cell splits

Prophase:The nucleolus starts to fades. The nucleolus then starts to meet into chromosomes. 

Prometaphase: This stage is where the nucleolus envelopes break down. This stage is when the proteins are being put together and where the two daughter cells are located. 

Metaphase: Tension to the spindle fibers aligns all the chromosomes in one place at the middle of the cell.

Anaphase: The spindles fibers have been shorten and the two daughter cells are being ripped apart. They later travel to the cell pole.

Telophase: The daughter get to the cell pole and the spindle fibers that ripped the daughter cells apart are gone. 

Cytokinesis: The spindle fibers start to break down. Contactile ring sticks the cell in two daughter cells. Next the newly made cytoskeleton is being recognized while the microtubules will return to the interphase stage later in the cell cycle.

the differece with plant cells and animal cells

Article posted December 14, 2011 at 08:16 PM GMT • comment • Reads 1105

1. they both have a nucleus.


2. they both have mitochindria which crates energy for the cell for various functions.


   The things that they have different is thatthe plant cell has a vacuoles, chloroplasts and a cell wall the animale cell dose not have a vacuoles, chloroplasts and a cell wall.three things are different except that the animale cell is way different to a plante cell because a plante cell of corse comes from a plane and an animale comes from an animale.

our brine-shrimp project

Article posted November 4, 2011 at 08:25 PM GMT • comment • Reads 1484

On November first we made an experiment to see what environment the brine-shrimp could live in. the way we did are experiment we filled the viles with things the we would think that the brine-shrimp would hatch in. Are first vill was filled with pop/smarties and water, next one egg/salt and water, third just salt water, forth pepper/smarties and water, fifth chocolate and water,last of all smashed smarties and water (the water was just tap) after 24 hours the brine-shrimp turned different colors they started at brown to really bright, also the brine-shrimp in vile (1) they sunk to the bottom and just floated. vile (2) the egg had trapped the brine-shrimp in the egg so we said that it was a dead vile. vile (3) the salt water had a lot of bubble!! we put them in a micro scope to see what was happening the eggs where hatching. vile (4) the pepper was sitting at bottom with the brine-shrimp we put that in the micro scope too and they where all dead. vile (5) the water was Smokey because of the chocolate we also put that in the micro scope too also dead. vile (6) the brine-shrimp sat at the bottom finally we had another vile that was alive! hatching ever second one after another! so we found that the brine-shrimp can hatch salt water and smashed up smarties. thank you.

Are Environment Lab

Article posted October 21, 2011 at 08:13 PM GMT • comment • Reads 1362

        The environment does affect organisms because the different environment changes the organisms to adapt and adjust to the environment like snow,heat,rain wind or just plant life. the lab that we did had five different substances the red sand, yeast, polyacylate crystals, seeds,and brine-shrimp, the polyacyate crystals, red sand, yeast appeared to be not living at first or even at all the organisms did not have the living side affects i was looking for in a living thing. Also the seeds, and brine shrimp appeared living because of the thing I have see what they turn into.the way they grow or changed was by the liquid we put into each substance we had we let the substances it in the liquid for more than 24 hour. the liquid was a mystery because mr.G didnt tell us what it was but after we where done with the substances we drained and disposed the the substances. The polyacylate crystals had/has grown but! it seemed that the polyacyate crystals just absorb the liquid. also the liquid was salt water. the thing i didnt get was the the brine-shrimp didnt go crazy as i thought it would of but they all died :( i just dont know why?

what is living?

Article posted October 7, 2011 at 08:19 PM GMT • comment • Reads 1597

The things i think makes a living thing is if it has a life cycle and a reperduction stage, if it can eat and has a digestive part of its body, moving and also breathing.

Global warming!!!!

Article posted October 3, 2011 at 08:19 PM GMT • comment • Reads 1474

1. Can people do something now to fix the global warming part of climate change?

A1: ways we can fix global warming and climate change:
- join local communities to shut down dangerous, dirty coal plants all across the state.
- to create cleaner ways to gain energy.

2. Should we do something now to fix global warming? Why or why not?

A2: should we fix it or do something to fix it:
- why global warming is important is because it can cause the ice at the north and south poles to melt which can cause a lot of flooding in many different places.

We put the rubber band on the newton scale & stretched it on the peg board to see how far it could go.
