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.

1. what happens to the light bulb when the washers fell? The light bulb will light up.



2. What do you think will happen when you put different numbers of washers on the paper clip and let them fall? The brighter the bulb gets.



3. Now put different numbers of washers, as indicated in Table 1, on the paper clip and let them fall. Make sure to copy Table 1 into your notebook. Record your observations in Table 1 in your notebooks.(Summary of the table.)



The more washers that are on the string, the brighter the light will go.

1 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?

The further a way from the fulkrum the less work you have to do







2. What do simple machines do to make our lives easier and how do they do it?

They do a lot of work for us.





3. Explain what happened when you used a lever to get your motor to lift the heavy sled.

The motor did not lelft the sled.

How does the Scientific definition of Work compare with our everyday use of the word Work? (How are they different?)



Work is when you get paid to do something. Scientific work means energy making something else move. The energy from the batteries makes the motors spin. The more elastic energy you have the more you can pull. Lifting a back pack up on a table is 20 Newtonmeters of work.

Title: 6th - EMM Lesson 7 (12/07/12)
Description:

Share your conclusion so that we can see what you got.





What is the best configuration to get those motors to lift the most washers they can?



 To use more battieries in a series, shorter stirng and more wires to lift the washers that you put on the paper clip.



How many washers can the motors lift?



1 motor can left 1 washer. 2 motors can left 4 washers. 3 motors can left 5 washers.



How much force did your motor generate in Newtons?



My motor generated 1.416 Newtons with 3 batteries.

1. What did you learn about controlled variables by doing the three friction labs?



I larned that you can change one variable at a time to get different data.







2. In this lesson you measured sliding friction. How do you know that you actually measured sliding friction? In other words, why does the force on the spring scale measure the force of friction while pulling a block at a steady speed?



we had to measure 27 centameters before we did the lesson. The scale shows how much force it takes to pull it at a steady speed and shows how much it wants to stop. 







3. Suppose you used ice as a surface type. What would you get for the friction force on ice with one block? What if you added two blocks, then three blocks on ice? What if you changed the surface area of the block on ice?



it would be easy to pull  because ice is smooth and doesn't have much friction if you added more blocks or wieght it would be harder to pull because there is more friction.







4. Write a conclusion based on your results for the three different manipulated variables, surface types, weight, and surface area.



If the surface was rough it would be harder to pull and mean more friction. If the surface was smooth it would mean less friction. The smaller the surface area the less friction there is. The more weight the more friction there is.

1. I would wrap it around the axle and pull the same way as the floor. 2. Pull twice as much on the rubber band. 3. Gravity. 4. Down. 5. Mass and density. 6. force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction en.wikipedia.org/wiki/Force What do YOU think Force means? - From Mr. G 7. The total weight increased by the exact amount of each washer I put on the scale. What does that mean about the mass? - From Mr. G

, kinetic, gravitational, sound, heat, light, chemical, electrical, elastic, nuclear

one day i got a stick and wrapped a bunch of spiderweb around it and played it like a guitar then hung it up and lit it on fire and then my dad turned on the porch light, opened the door and said a nucclear bomb hit seattle. THE END
