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.

Interphase: Cells may appear inactive but the opposite. This is the longest period of the complete cell cycle during which DNA replicates the centroiles divide and proteins are actively produced.
Prophase: the dulplicated chromatin become tightly ceiled to form chromeosomes.
Metaphase: the spindle fibers exstend to the chromosomes and alighn them at the center of the cell.
Anaphase: The spindle fibers shortend and the and the sisters chromatid are pulled to the opposite poles. Each chromatid becomes a complete chromatid. The cell elongates.
Telophase: the daughter chromosomes slowly become less condence to form chromatid fibers. The splindle fibers dissapear and the nuclear envelope begins.
Cytokinesis: the division of Cytoplasm occurs once telophase is over. A cleavage furrow containing a contractile ring develops seperating the two new formed nuclei. The furrow deepers to form two identical cell.

Cell type structure and function

Article posted February 5, 2013 at 11:51 AM GMT-8 • comment • Reads 325

Root Hair Cell From A Plant
Function: to help absorb water like a sponge.
What helps it carry out this funtion? the root hairs are in the ground where the water is absorbed.
Muscle cell
Function: to help you move your limbs.
What helps it carry out this function? The cells build up the muscle, and the muscle moves with your body,helping you
Nerve cell
Function:Helps you feel.
What helps it carry out this function? The feeling goes through your nerves, then to your spinal cord. Then to your brain and tells your brain what you feel.

Prokaryotes and eurkaryotes

Article posted February 5, 2013 at 11:43 AM GMT-8 • comment • Reads 300

The major difference between prokaryotes and eukaryotes is that eukaryotic cells contain membrane-bound compartments in which specific metabolic activities take place.What i know is prokaryotes unicell organism having cells lacking membrane bacteria are the prime example but also included are blue-green algae.

I got it from this web site http://www.chacha.com/question

the group i am in had 2 eggs we put one in monster with the weight of 71.96 grams and the other egg in vitamin water with the weight of grams. The monster egg went up 7.8% (5.61 grams). The vitamin water went up 6.2% (4.25 grams)

pants vs animals

Article posted December 13, 2012 at 01:05 PM GMT-8 • comment • Reads 430

Plant: has a chloroplast. have a cell wall. the cells are more square and angular. don't have a lysosome.

Animal: has a lysosome. doesn't have a cell wall. cells are more free formed and round. don't have chloroplasts.

Both: have a vacuole, mitochondrian, ribosome, cell membrane, nucleus, golgi bodies. they both keep things living.

one thing that the plant can do and the animal can is make there own food. one thing that the animal can do and the plant can't is move around.

I think person number two is right because the organism is something that is put together to make a living creature so I think that person number two is right.

two spade buck tooth whale

Article posted November 5, 2012 at 01:02 PM GMT-8 • comment • Reads 169

The world's rarest whale has been spotted for the first time, in New Zealand, where two of the whales stranded themselves.

The two spade-toothed beaked whales, a mother and calf, stranded and died on Opape Beach on the North Island of New Zealand, in December 2010. The mother was 17 feet (5.3 meters) long and the calf was 11 feet (3.5 m) long.

A report describing the whales and the analysis of their DNA will appear in Tuesday's issue of the journal Current Biology.

"Up until now, all we have known about the spade-toothed beaked whale was from three partial skulls collected from New Zealand and Chile over a 140-year period. It is remarkable that we know almost nothing about such a large mammal," Rochelle Constantine, a marine biologist at the University of Auckland in New Zealand, said in a statement. "This is the first time this species has ever been seen as a complete specimen, and we were lucky enough to find two of them."

At first, the animals were thought to be much more common Gray's beaked whales. Their identity came to light following routine DNA analysis, which was done as part of a 20-year program to collect data on beaked whale species in New Zealand waters. New Zealand is a known hotspot for whale stranding, and it has the highest rates and greatest diversities of stranded whale species in the world, the researchers report.

The New Zealand Department of Conservation photographed the animals and collected tissue samples.

"When these specimens came to our lab, we extracted the DNA as we usually do for samples like these, and we were very surprised to find that they were spade-toothed beaked whales," Constantine said. "We ran the samples a few times to make sure before we told everyone."

The researchers said they have no idea why the whales have remained so elusive.

"It may be that they are simply an offshore species that lives and dies in the deep ocean waters and only rarely wash(es) ashore," Constantine said.
