Take out Lever Activity (page 17) or get one off of the front table.

Today- Follow directions on Lever activity to the best of your ability. You do not need teacher signature when it asks for it.

Read this and understand you must start with the Blue because it is more accurate when the force is less than 2.5 n You do not need teacher initials when it asks for them

Setup- Measure and secure fulcrum 15cm from edge of table…

Part 1- First class levers Fulcrum at 70 & 100cm edge over table Weight at 2cm Apply effort force like this 70cm100cm 2cm Apply force down

Put the top handle around the meter stick and pull down with the hook

Make sure fulcrum does not hit table and only balances on table

Part 2- Second class levers 100cm Binder Clip 1cm end Apply force up Move weight according to directions “Fulcrum in the middle”

Part 3- Third class levers 100cm Binder Clip Weight at 1 cm Apply force up Move Binder Clip according to directions “Effort in the middle”

Read this and understand you must start with the Blue because it is more accurate
