Friday - Schoolyard Report Card

Today we discussed salt and salinity of the oceans. The ocean is about 3.5% salt, similar to the amount of salt in your blood. We measure salinity in science in parts per thousand, so the ocean is 35ppt. The dead sea is over 300ppt!

Students went for a walk around the school property today to get a better idea of the kinds and percent coverage of vegetation. We discussed groundskeeping, cars in the parking lot, runoff and more. After returning to the classroom, students filled out a reportcard for the school concerning how this school could affect the Chesapeake Bay.

Students were surprised to find that our school scores around 100% or higher because of the amount of open space and ground that is not impervious (covered in pavement). We discussed how schools in more urban areas might have a tough time scoring this high.

Computer Lab Etiquette

You are in the computer lab to do work for this class. If you are not doing work, then we will have problems.

Do not pack up early. Work until the bell or until MsJ says.

SAVE OFTEN. And if you save to a key, also save it to your number. If you lose it, you will have to do it again.

If MsJ asks for your attention, stop what you are doing and listen to what she has to say.

You may watch videos about your organism through reliable websites.

You may listen to music through the computer if you have your own headphones. Rule1 MsJ cannot hear it. You get one warning. Rule2 Turn it on and listen – no million clicks and constant changing. Take both ear phones out when MsJ is talking.
