Science at Bangor & in the News
Unfortunately, chemistry did not really meet at all this week because of state testing. We will start back at it tomorrow with an experiment to kick off our unit on representing chemical change.
Science 9 did meet last week. We continued our unit on forces by working on how to represent forces is different situations. The most difficult part was probably remembering which of our 7 (!) forces was being used. We will continue to work on the vocabulary and identifying forces as the unit progresses. At the end of the week we started focusing on the force of gravity. We used spring scales (Thank you, Ms. Wenger!) to measure the mass and weight (force of gravity) on various objects that were around the classroom. When we analyzed our data, most groups had very similar constants for the force of gravity. During our discussion we agreed that this made sense since we are all on the same planet and gravity is the same no matter where we are on Earth. Our data showed that the force of gravity on Earth is about 0.01 Newtons for each gram, or 10 Newtons for each kilogram. The actual force of gravity is 9.81 Newtons for each kilogram...I was very impressed with how close we were able to get with simple spring scales.
