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.

Day One: The highlight was seeing the spot where the first elwha dam stood. We also went to Salt Creek.
Day Two: We went to the Hoh Rainforest.
Day Three: We did the Ozette hike.
Day Four: We went to the Makah Museum and Cape Flattery to see Tatoosh Island.
Day Five: We went to the Marine Center.
My favorite part was on day 2 when we went to Sol Duc Hotsprings.
Something i didn't like was the small food portions but I liked the food.

What I know.
They're slugs in a shell. They grow out of there shells and they dry out if salt in put on them.
I want to know if they can see color, if they can smell, and how much weight they can pull.

My team (Zach and Justin) did an experiment on a Cardon cactus or also known as the False Saguaro. The Cardon is native to Mexico, Baja, and California and is one of the deserts most magnificent giants (but our cacti's were only 8.5"). My cactus can grow to 30' in height, with bases up 3' in diameter. The lifespan is 100+ years. The experiment: We had three cacti's and put them in three different environments. One being 98F (in an incubator), another 68F (room temp.), and the third at 37F (in an fridge). To control variables we had to change some things. One, the cactus in the fridge didn't get light so we covered the plastic door of the incubator and put the room temp. cactus in a closet, so now all three are getting no light. Two, we watered the cactus every other day with two squirts of a water spray bottle. The hypothesis is that the cactus the incubator will look the healthiest by the time our experiment is completed because cactus, being native to the desert, will grow the best in the hot climate. Here is our table of results:
As you see we were wrong, the hot climate Cardon cactus started to burn and the room temp. cactus did the best. Inaccuracies we had were one, the room temp. cactus had air circulation and plus at night when the heat was turned off the temperature change which is essential for cactus. Click Here is a movie I made of when my teamate cut open a cactus.

My lunch was a cheeseburger, with jam on bread followed by a banana, yogurt and a glass of orange juice. The total miles it took to get it here was 11,538. To convert that mileage into pounds of CO2 you have to multiply every mile by 3.67. The product of that is 43,267.5 pounds of carbon. That's the weight of 4.3 elephant!

Offspring that have been produced sexually have more diverse characteristics than being produced A sexual. Why? Because of genetics. When homozygous and heterozygous traits mate the more dominant trait over throws the recessive one. For example if u
, you'll see a Punnett square. The BB is homozygous and the Bb is the heterozygous. As you see there is a 50% percent chance of BB and Bb. So to go further there is a 50% 0f thick eyebrows and 50% of thin eyebrows.
The following URL is a collection of Punnett squares I have done. http://educatoral.com/rm604/images/per3/g2/Genetics/

In our class we have done a project that could have endangered us all. We were dealing with organisms that could've killed us if we were unsafe and did not get treated if infected. Now you're probably wondering what were these eigth graders doing? We were observing the bacteria in our school. Another objective was figuring out where was the most dirty place in our school. Out of the four locations we swabbed (sink, water fountain, ceiling, and urinal) we found that the urnal contains the most bacteria. The next location was the water fountain, following the sink, and after that the ceiling. I conclude that there is indeed bacteria in our school and depending on the location there can be millions.

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.

A lot of differences are the looks. Plant cells are typticaly round to square while an animal cell, more specificly an parameciumis oval with little cilia lining it. Also another difference it what it has. Animal cell has a gullet, the cavity of the pharynx, while the plant doesn't have one. But a similarity is the both have nucleus which is the most useful organelle of the animal cell, paramecium. I conclude that both type of cells can be simimlar and different.

My team was studying paramecium under a digital microscope. We found evidence of movement. the video we filmed shows at the beginning paramecium moving around, here it is.
It's a little fast.
