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.

The highest number of washers lifted in period 5 was 9 washers. The configuration that would lift the most washers would be: using 3 batteries in a series order, 2 wires, short string, and, not completely sure yet, a nail, not pulley.

in this lesson i learned that u needd shorter string, ur batteries in series, 2 wires, 3 batteries and a nail. if u put it like this u can lift a lot more washer's.

What was the highest number of washers our motors lifted?
We lifted a highest of nine.
What configuration of motor, batteries, string, wires, etc. accounted for the highest numbers of washers lifted?
We need to put our batteries in series, have three batteries, put the string on the nail, have two wires and have a short string.
Can this lift more than nine washers?
It should be able to lift more than nine washers.

When I added more batteries to our teams circuit, the more washers it could lift.
My hypothesis was correct because 1 battery lifted 1 washer, 2 batteries lifted 4 washers and 3 batteries lifted5 washers. something would change is going slower so the washers don't fly off amd hit you in the face. I liked doing series because the washers lifted up faster!

Series.
3 Batteries.
Nail.
2 Wires.
Short String/Distance.
Motor.
The reason i wrote this is because, we are doing an experiment with all these things in science! The experiment is to see how many washers a motor/pulley can pull up! My groups motor/pulley pulled up 9 washers! Do you think it could pull up more than 9??
