1. 8th Gr. Science – 12/17/15 Work on Lab Book Today’s Plan:
Homework (write in planner!):
Work on Lab Book
Today’s Plan:
Finish your Bottle Rocket!
Tomorrow = Final Launch
*After school launches today only for those who couldn’t launch yesterday due to lack of time.

2. Bottle Rocket Modification Day
Check your parachute – design, folding method (it must deploy at apogee)
Check your nosecone – shape, mass, clay, ability to stay on then fall off at apogee, tabs (everything needs to be balanced, stable, centered, etc.)
**YOU MUST SECURE YOUR CLAY WITH DUCT TAPE (free) – if it releases from your nosecone during your launch, you will lose 10 points!!
Check your fins – shape, placement, size, condition (shouldn’t be bent!) – check Hayhurst’s guide on Schoology
In your Lab Book, record the following: mass of clay, total mass of nosecone (with clay), length of rocket, # of fins, length of fins, how far fins protrude from rocket.
NO BUYING OR BUILDING TOMORROW!!
