 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. Mr. G's Blog Mr. G's Class Facebook Page

That is why we invented the wheel. To reduce friction.Different surfaces create different friction levels that is why we play hockey in an ice rink and not a sand paper rink. Friction does not really go in a direction because friction slows objects when there rubbing against a surface that is why it does not have a direction. Friction keeps objects from moving because the rule "an object in motion tends to stay in motion unless acted upon by an outside force." That same rule applies to objects that are not in motion.

(write a compete description of it) My water quality parameter is turbitity. Turbitity is a measurement of how foggy or cloudy the water is. It is determind by how many solid particles are floating in the water the more solid particles that are in the water the higher the turbitity and the more cloudy it is. Q2: How does it affect water quality? Turbitity will make the water less safe to drink think about it would you rather drink dirty water or clear water. The longer a fish lives in a body of water that has high turbitity levels the more stressed it will get until it dies. Q3: How is it measured what levels are good what levels are acceptable what levels are bad? Turbitity is measured in NTUs. A good level would be around 0. An acceptable level would be around 0.5 because that is the highest level that is acceptable to be drank by humans a bad level would be 0.6 and up. Q4: Turbitity affects humans by making water less drinkable. It affects fish by blocking sunlight from getting into the water witch disrupts photosynthesis and smothers the fish. It can also go straight to the salmons gills and kill them. The longer the fish stays in water with high turbitity the worse its condition.

They also need clean and cool water it helps if there is shade. Some threats to salmon eggs are that redds can be destroyed by people or animals crossing the river also dirt can wash into the river and land on the redds smothering the eggs. An alevins length is about one inch and has a yolk sac. Its needs are that it needs the protien, sugar, minerals, and vitamins contained in the yolk sac. the alevin also has many threats such as gulls, dippers, sculpins, and trout. The fry will start to develop vertical parr marks and spots as they grow. A fry needs to have bugs to eat and wooden debris to hide under and cool water. The threats to a fry are that previus logging practices have already caused problems. A smolt has bluish greenish back and has tolerance for salt water. The smolt needs to have things called juvenile bypass systems they are man made creations that help the smolt get past dams. A smolts threats are hidroelectric dams, predators, and pollution from cities, factories, and farms. Sea run adults are silver until they go back to there home stream. They need small fish to feed on such as shrimp, and squid. There threats are sea lions,Orca whales, and seals another threat is commercial fishermen. A male spawner has a hooked snout and it also changes its silver colors to brilliant colors. The female spawner does not have as brilliant colors as the male but the female changes colors too that can vary from reds to browns depending on the species. A spawning salmon needs a mate A spawning salmon also needs to have the color changes to attract a mate. A spawners threats are fishermen, all the predators they faced going downstream and more. A spawners predators are bears, wildcats, and eagles. Article posted January 5, 2011 at 10:07 PM GMT • comment • Reads 965
