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.

We did an experiment this last week on whether cockroaches preferred a rocky surface over a grass surface. 3/4 trials we did, the cockroach preferred a rocky environment over a grass surface. Though most of the time it just sat there and cleaned it's antennas.

This week were learning about COCKroaches! The Madagascar Hissing Cockroach is one of the largest species of cockroach, reaching 5-7.5cm at maturity. You can usually find them in rotting logs, and unlike other cockroaches they are wingless. They are excellent climbers and can scale smooth glass.

I know that cockroaches can withstand a nuclear holocaust and there really tough to kill. I would like to know what there diet consists of, and if they can swim at all.

Odyssey

I thought Odyssey was a really good experience for myself and the rest of the 8th grade. To be out door's and breath in the air of beautiful Lake Crescent and to go everywhere we went, it was amazing. One of the things I learned is that the Hoh Rain Forest gets an annual precipitation amount of 137 inches of rain a year. The Hot Springs were awesome, it smelled really bad! and the Ozette hike was grueling(really hard). But all in all it was a fantastic experience.

We did an experiment with snails and hand sanitizer and hand lotion. We tested whether the snail prefers hand sanitizer or hand lotion the results is that the snail went to the lotion 3 out of the 4 times we tested it.

Plant Expirments

This week my team and I had a Plant Project on carnations and food coloring, where we put the carnations in veil's then watered them with food coloring. My claim was that 50% or less of the stem would turn blue and/or red. My evidence was that our results came out to be that the plants died at the end with little color on the stems, and the tips of the flower, all of our predictions were wrong. My research was, vascular plants have plant tissues, which circulate resources through the plant. This feature allows vascular plants to evolve to a larger size then non-vascular plants, which lack these specialized conducting tissues and are therefore restricted to relatively small sizes.

Bacteria in our school

My team and I did an experiment with bacteria in our school we tested computer keyboards, door handles, a lunchroom table,and a bathroom seat. One of my questions was, what has the most bacteria?,I predicted that the door handle would have more bacteria, we swabbed it and over time it grew more than anything else so it was the door handle! We had a medium amount of bacteria between the others, amazingly the lunchroom table had more bacteria than the bathroom seat. From what I have seen it seems as if, the more that different organisms touch something the more bacteria grows on it.

Mitosis

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.
