Let’s take one last look at our
Egg Challenge:
1.Did your egg have energy? It fell a distance and cracked changed”.
2.Was it forced through a distance?
3. What force pulled it to Earth’s core (distance)?
How can we quantitatively (#) prove the egg had energy, used energy?
Copythe PE=m gh and diagram on the boardKE= .5 mv²
Agenda:
1. Bell ringer
2. Copy the Law
Law of conservation- says
Energy can’t be created nor destroyed only transformed (changed) or transferred(moved)!
- Compare the PE and KE of your egg and use the Law of conservation to explain the results! Calculate the PE of your egg drop:
- Prove the Energy was conserved! Calculate each!
PE=mgh KE=.5 mv2
PE= mass gravity height
PE = ___kg 9.8 m/s2 20 M
PE= _____ NM
PE = _____ Joule
KE = .5 (mass x Velocity2)
KE = ___kg __ m/s
KE= _____ NM
KE = _____ Joule
Law of conservation: PE + KE = Total Energy
Subtract the PE- KE = ______
You have to account for where the energy went!
List all possibilities:
- ______
- ______
- ______
The biggest waste of energy is in the form of heat due to friction!!
Agenda:

Bell Ringer:
Make a list of all the data you need to calculate the PE (Potential Energy) stored energy and KE (Kinetic Energy) moving energy. See if you listed at least these things!
Agenda:
Follow directions on colored paper-
leave sheet on table please!
Materials:Data______
Control copter-built exactly as instructed
Sketch dimensions
Manipulated copter- modify (if mass check out a big paper clip; if length of wings you choose how short to cut) Sketch dimensions

Why would Santa need the rain deer to truly be reindeer-copter?
Calculate the velocity Santa would have to go; in order to travel 25,000 miles in 24 hours.
V=d/t
Frustration is the 1st sign you are about to learn something new or improve skills!
How many of us get frustrated at reading instructions?
Almost everyone
Preserver!!!
Let’s get together and make these reindeer-copters
Check you wrote the parts of your experiment up then show your data table for a sticker to hold back of copter together
Test and record its flight times!!
Breath your way into the Learning Zone!

Bell Ringer:
List as many types and functions of helicopter as you can in 1 minutes, brainstorm with partner 1 min add to list; now in groups of 4 Your color of team, take 2 minutes to compile the list.
List on the board assigned to your team.
Calculate the Gravitational PE =m g h
For the control then the modified.
Calculate the Gravitational KE= ½ m v²
For the control then the modified Trial2.
Complete trials if not already done.
Analysis –
- Look at the data teams recorded; did mass or length of wings make the biggest impact on the time in flight?
- Does mass effect the amount of PE?
- Did the mass effect the time in flight? How?
- Did the length of the wing effect the time in flight? How?
- How can you make you helicopter stay in flight longer?
- If you had to carry a heavy load, what type of helicopter would you need?
- If you needed to move quickly, which type of helicopter would be best?
- Explain how you are going to modify your helicopter and for what purpose will it have?
Test you design!!!! Record data!!!!!
