Mr. Cosby

How to earn the optional extra credit for participating in the Science Fair if you are in Mr. Cosby's class:


Trimester 2 Extra Credit - up to 25 points

Trimester 2 extra credit is about conducting your experiment and showing me your progress over the course of one month.

These Due Dates are rigid. If you start late, or if you do not send a picture by the due dates, you will not get the points for that turn-in date. This does not exclude you from turning in a different week's picture or exclude you from participating in the science fair! You can still be in the science fair and get 3rd Trimester extra credit without doing any of the below extra credit assignments!

Note - some students do their entire experiment as soon as they can so they can get it out of the way. If this is you, just take pictures of each of these steps during those few days and email me the correct picture on the correct due date.

Trimester 3 Extra Credit - up to 25 Points

Trimester 3 Extra Credit is simple - complete your science fair project on time, and participate in the actual Science Fair on March 1st.

  • You need to enter an actual project in the Science Fair. (Set it up on February 28th, participate on March 1st, 2022.)

  • You need to be present at the actual Science Fair. IF YOU SET UP A PROJECT BUT FAIL TO BE PRESENT DURING THE JUDGING, YOU WILL GET 0 POINTS!

  • Your extra credit points will be based as a percentage of the possible points you receive from the judges.

    • So, if your average score from the judges turns out to be a 72%, then your extra credit will be: 25pts x .72 = 18 points. Not a bad way to pad your 3rd Trimester grade!!

  • The Science Fair Extra Credit is THE VERY LAST GRADE entered into the gradebook at the very end of the year.. usually 1 - 2 days before we are out for the year. Don't worry, it will be there!
