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.

Our experiment involved cacti. We wanted to know what environment would be best for cactus growth. We had a cactus in the incubator about 93 degrees F with paper over the incubator door window we also put one in a mini fridge 45 F no light either then we had a cactus in the closet for room temperature 76F. Our controlled variables were light exposure and the amount of water we gave the cactus which was two squirts from a spray bottle every three days. Inaccuracies the cactus in the closet was exposed to more sunlight because other teams had their experiment in the closet so it was opened often. The fridge was opened for food often as well. Another problem was that the temperature in the incubator was too hot for the cactus at 93f when a cactus is better in 85f degrees. Our cactus was a Cardon or false saguaro is native to Mexico and Baja California. It grows to 30 feet in height and 3 feet in diameter. Also its lifespan is 100+ years. Here is a movie made by my teammate of my cactus being cut open.

I know that the largest snail was 2pounds and 15 inches
They grow out of their shells when they get to big they excrete a calcium protien that harden into the shells.
They are realated to slugs are both genders.
I want to know how long they can live how much weight can a snail pull? Why salt hurts them? Why are there aquatic snails?

Sexual reproduction gives more variety because each parent has a differnt geno type so the baby will be differrent than thier parent. Asexual reproduction is miotosis the split of into two organisms of the same geneo.

We learned that even in school bacteria can grow with the right conditions. Millions of bacteria grow every where in the sink,in the water fountain,in the urnial, and the hall way ceiling. The urnial had the most bacteria in it with the auager the bacteria florished the food the water and heat were the right conditions the colonies were a ivory kind of color. All of the colonies were that color, imagine the amount of bacteria wich are every were live on us and most things we touch.

enviroments effect organisms by the food sources, predetors, repreductions, hacthing and habitat.
the organisms appeared non living because the enviroment was not sutible for the type of organisms in the lab test we did but that depends on the type of a liquid. The test we did was we took three different liquid sugar water, salt water, and regular water. My team used salt water and we put brine shrimp in the salt water and they didn't hatch then we put polyacrylate crystals they are exorbitant they hardly did any thing they expanded a little but not much. Then we put radish seeds an a cotton ball with some salt water in it but it didn't grow. Next yeast was put in the salt water and it hardly did anything it sank and thats it. Last we put red sand the water and nothing happened.

There is not much humans can do to stop global warming we can try to slow it down but unless we some how got a gaint co2 transfer device and remove some of the co2 out of the atmosphere which is highly unlikely we can't stop it even we did it would just come back, but we can try to slow it down. We need to try to help the envoirment but not waste our money and go over board.

I'm here to tell about newtons first law . The law of inertia. If a object is at rest it will not move unless acted upon by a outside force.Like a ball on top of a hill it will not move unless a outside force like the wind comes and blows it away
