 Jonah's Blog 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

What happened to the effort force, effort distance, and the amount of work you did to raise the sled .1m when you used a lever? (Explain what happened as you got farther from the fulcrum or pivot point.) A1. As where I pushed down got away from the foulcrum it got easier to push down. Q2. What do simple machines do to make our lives easier and how do they do it? A2. Simple machines make life easier becoase we can do more N-M of work with less effort. Q3. Explain what happened when you used a lever to get your motor to lift the heavy sled. A3.When I Used the motor and the lever to lift the load it could lift more than withought the lever.

You can calculate the power by Dividing the Work by the number of seconds it took to do the work. 2. If a lightbulb has 100w then it does 100nm of work per second. 3. 750 watts = 1hp 4. yes Because when its in seres the watts of the batter adds up making it have more watts. 5. As I added more batteries the motor could lift more. 6. My time graph and my power graph were different becuase the time graph measured the amount time it took for the motor to lift the washers but the power graph measured the amout of power 1 battery generated. 7.If I needed to lift a bigger load i could add more batteries. 8.Yes 4.25 Volts lifted the load.

The scientific definition is of work is how many newtons an object wieghs multiplied by the length in meters you moved the object, so you can study all night and not do any work.

 Article posted December 11, 2012 at 08:25 PM GMT • comment • Reads 1100 I found that one battery generated 1 newton of force. My hypothesis was as the number of batteries increased the force the motor could pull increased. I was right. This happened because one battery had 1.2volts but as more batteries were connected the volts increased. Data: 1 battery= 1 newton 2 batteries= 2 newtons 3 batteries= 3 newtons Article posted December 11, 2012 at 08:25 PM GMT • comment • Reads 1100

I learned that controlled variables are very important, if you change multiple variables you don't know what variable did what. 2. The spring scale can measure friction because with the block on the hook, well, the block touches the ground and as you pull it, it has drag pulling on the spring scale telling you the friction force. 3. If you put the block on ice it would have less friction than the other surface types. If you but more blocks on the other block it would have more friction than just 1. And if you changed the surface area It would change by a little bit. Conclusion: I conclude that weight of the block makes the biggest difference in friction force. I thought that the surface types would make a bigger difference. As the surface types got rougher the friction force increased, and as the blocks increased in weight the friction force increased, but as surface area increased the friction force DECREASED.

A thicker rubber band 3.Gravitational 4.Down 5. Some are more dence than others 6. Force is something that acts on another thing 7. When I added more washers the weight of the washers increased. I said that when the number of washers increase the weight of the washer increased, I was right. One washer weighed 0.25 newtons, All of the washers together weighed 1.25 newtons. I think this happened because each individual washer has its own weight therefor when each washer is added to the hook the weight increases for every washer that's added.
