Popcorn Lab
Problem:
What impact does popping have on it's mass
Hypothesis:
I think the popcorn will be lighter when popped.
Materials:
Beaker
Bunsen burner
Ring stand
Popping corn
Tin foil
Oil
Must of metal
Procedure:
1. Gather materials
2. Add oil to beaker
3. Add pop corn to beaker
4. Use must of metal on ring stand
5. Put beaker on ring stand
6. Start burner
7. Repeat 2-6
Observations
Our first trial, to popcorn was burnt so, we didn't count that.
Our second trial showed that the popcorn actually weighed more than the unpopped
Solution:
We have deemed that popped popcorn is actually heavier when popped because of the extra mass we thought would be added. This surprises us, as we thought it would be lighter.
My Notes
(for my personal reference)
1:08 PM
Newton's laws and such:
When forces are balanced there is no movement.
An object at rest wants to stay at rest. It does not want to change in motion.
When in motion, an object will remain in motion in the same direction until an unbalanced force acts upon it.
Force=mass(acceleration)
Mechanical advantage:
Output force over input force
Output
Input
Output- What comes out
Input- what you put in
Fulcrum- where it rotates
Science Blog
I will give and ask for meaningful feedback to people in this or other science classes.
I should embed data tables and graphs into my blog
Acceleration= final velocity- initial velocity time
