Chimacum's Science Blogs-

Mr. Gonzalez's Science Classes

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.

A force is pushing, pulling, and moving. If you used a rubber band To launch a cart across the floor you could double up the rubber band And put the cart in the middle of the rubber band then pull it back and let it fly.

Weight is gravity,and mass is what you add to you.

if you wanted to pull a bike with a rubber band it would work but it wouldn't stretch out long enough to actually pull the bike because of all the mass beyond the rubber band.And mass is something that is made from weight/ so kind of another word for weight in a way. rubber bands can only go/stretch out so far until the weight is to much for it to take then it snaps

To get a cart across the floor using a rubber back I'd use a slingshot.



Mass depends on what the item is and weight is how heavy an object is.

I learned that gravity pulls down into the center of the eart. Mass is what something is made of and weight is how much gravity pulls down on you.

What are some ways to use elastic force to propel a cart across a floor?

You can pull the cart.

You can use a slingshot to fling the cart.

What is the difference between mass and weight?

Mass is what is inside the object. Weight is how much the earth is pulling down the object.

Do pull a cart across the floor you can take a rubber band and tie it on the cart, pull it back, and let go! Pulling rubber band and letting go is a lot of force.

Weight is dependent on gravity and mass is dependednt on weight. So in conclusion, i learned weight is how much gravity forces down on you and mass is what something is made of.

I leared elastic force!
