 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

When my team measured the friction of the blocks, the work was 0.189 Newton-meters. The motor used 0.2 newton-meters. Article posted June 15, 2012 at 03:19 PM GMT • comment • Reads 1273

For example it takes less friction force to pull a block on waxpaper than on sandpaper. In inquiry 6.2 I learned that the more weight an object has the more friction force it takes to pull it. For example 1 block of wood will be easier to pull than 2 blocks of wood, In inquiry 6.3 I learned that different surface areas will take different force of friction. For example a short narrow side is harder to pull than a wide long side. We measured sliding friction by pulling a block with a spring scale. We used the spring scale to calculate how much friction force it took. I learned that when constructing an experiment you must only have one manipulated variable and one measured variable. All the other variables are controlled. Otherwise the results of your experiment may vary. For example in our experiment of different surface areas the conrolled variables were the pull distance, the speed, slope, and suface type.

 Article posted May 4, 2012 at 03:29 PM GMT • comment • Reads 979 I think that middle schoolers should get to read for an hour a day at school. This way students will be reading more often. reading is an important part of life. If someone was reading a book and it took them a month, they would appear very illiterate. Read ing is an everyday activity as well as a source of entertainment. Instead of playing video games students could read a book. I am so sad to see my peers who treat reading like a punishment instead of a privilege. There was a time when only very rich and very important people were treated to the art of reading and writing. We are lucky to be in a time were such creative and brilliant minds live. This is why I think that we should get to read for an hour a day at school.

I like to write. Stories, poems, other things. I decided to write a poem for all of you. River Water River water everywhere, River water in th air. River water on the ground, River water I have found. River water I can see, River water it may be. River water with you and me, River water can't you see? River water is quite calm, River water has soft palms. River water can not end, 'cause river water is my friend. Article posted May 1, 2012 at 03:01 PM GMT • comment • Reads 1080
 Article posted April 25, 2012 at 03:32 PM GMT • comment • Reads 1028 One way you could propel a cart across the floor is to pull it with a rubber band. But that is boring and plain and unoriginal. Another way to move the cart is to snap the rubber band on the back of the cart so the cart propels forward. You could also twist the rubber band around so the wheel flies forward. You could also make a catapult. But enough about that, now is a time to talk about the difference of mass and weight. Mass is more like how much space you take up. As weight is how much gravity is pulling you toward the center of the earth. To measure mass you use a balance. To measure weight you use a scale. We learned how the increase of mass increases the weight. We measure mass in grams and kilograms. We measure weight in pounds or newtons. Force is a push or pull. Force affects something or causes something to happen. Article posted April 25, 2012 at 03:32 PM GMT • comment • Reads 1028
 Article posted April 19, 2012 at 03:19 PM GMT • comment (2) • Reads 1068 My dream job is to be a teacher. I have always wanted to teach people and I think it would be a fun job to have. I love to help people and I love schools, so being a teacher would be very nice. I would also like to be an author. I love to write and read. I like to use my imagination and come up with ideas.

 Article posted April 17, 2012 at 03:06 PM GMT • comment • Reads 1120 I learned that in 2010 we used 811 more pounds of carbon than in the 1930s. That is so amazing. It is also scary. We have more cars and less trees than before. But now we have solor powered road lamps. So we have negative and positive affects on the amount of carbon released into the environment. Insulation helps conserve energy by using less enrgy to cool orwarm a room. I learned that to be safe with electriciy you need to be careful when you are using electrical appliances. You need to keep things that could dangle into lights out of the way. You need to make sure that only bread is put into toasters. That only electrical plugs are in electrical sockets. The fuels that put less carbon in our atmosphere are solar power, wind power, andd nuclear power. These kinds of power are unlimited and dont get used up. Other kinds of fuel like oil or coal aren't unlimited and can get used up. Article posted April 17, 2012 at 03:06 PM GMT • comment • Reads 1120
 Article posted March 22, 2012 at 03:35 PM GMT • comment • Reads 1178 When a battery gets charged electrical energy goes from the cord plugged into the wall into the battery. Then the eletrical energy flows into the battery and turns into stored chemical energy. Next you connect the battery to the light bulb. The stored chemical energy turns back into electrical energy. Then the battery turns into heat and light energy. That is the kind of energy that light bulbs use. Motors use mechanical energy. Soon enough the battery runs out of stored chemical. Then the battery goes back into the charger and gets charged again... Article posted March 22, 2012 at 03:35 PM GMT • comment • Reads 1178
 Article posted March 19, 2012 at 03:33 PM GMT • comment • Reads 1387 Zinc, copper, a blotter paper, a grain of white, and copper sulfate solution make a battery by creating a full circuit through from the zinc to the copper sulfate to the copper to the light bulb and then to the zinc again. The blotter paper prevents the battery from short-circuiting. The zinc releases a negative and the copper gets a negative. This makes zinc the positive side of a battery and the copper a negative side. This is how zinc, copper... make a battery. Yay. Article posted March 19, 2012 at 03:33 PM GMT • comment • Reads 1387
