Tech Ed Review Packet

INFORMATION & DIRECTIONS-‐ Please read!!!!

This packet is due on THURSDAY, February 14th

Use the reference sheets listed on gatelyscience.com to answer the questions. If you need a printed copy of the reference sheets, let me know and I can make

you one.

You must also complete the two Edpuzzles! (“Buoyancy” and “Thrust, Drag, & Lift”) that have questions and notes!

Write notes in your journal. They will be checked on Friday.

We will review the answers in class on Thursday and play Quizlet Live to review, so you have the answers for Friday’s test.

Your Tech Ed Test is on Friday, February 15th

If you are NOT going to be here on Friday, you MUST schedule a time with me

to take the test BEFORE VACATION!!

I may not see you one of the days due to scheduling changes, but you still must get this done! I am available at lunch if you need help. There will be no lunch

for JogNogs this week.

See me or email with any questions.

Good luck!! J
