95:180 Chemistry of Change pt. 1

NS&E is exploring chemistry right now to prepare in building batteries from common parts. This is always a fun build because there are so many unique results with groups and the students enjoy seeing the differences. Every year I go to the bank to get a new batch of pennies to be cleaned using our process.

But this year when I opened the box of pennies from the bank I had a small problem…they were all new and straight from the mint!

a box of 25$ worth of pennies
25$ worth of pennies, surprisingly heavy!
an open box of 25$ worth of brand new pennies, very shiny orange-pink
25$ of brand new mint pennies – pretty, but not good for our activity

60:180 Light ON!

Lightbulb Investigation 2018 from Heather Waterman on Vimeo.

Students did a great job this year building their light bulbs from some wire, batteries, pencil lead, and a binder clip.

46:180 Python Returns

Students worked today investigating how to write more sophisticated code by using modules and using example code to design their own. By “breaking” code we’ve been able to analyze what are the essential pieces needed to do tasks like calculating Gravitational Potential Energy or velocity if only energy information is known.

26:180 Happy Birthday Dr. Mae Jemison!

We name our equipment after women in STEM, better than just Car 1, Car 2… and today is Dr. Mae Jemison’s birthday read more from her NASA biography here.

Students have a goal of developing a proceedure and data table (which must get approved before data collection can begin).

18:180 Ruler Car

2nd build has begun

We had a late, but great, start to the year so far. We are finishing up our first unit “Balloon Pop” where students learn to work in teams, analyze data, and discuss the differences between precision and accuracy.

 

185:180 Summer Reading – Chasing Space

Today is last day of school. Another great year where I am thankful to work with such great students and colleagues.

I’ll be reading “Chasing Space” by Leland Melvin for my Summer Reading.

180:180 Final Rube Goldberg Projects

178:180 Tap, Tap, is this Mic on?

As per usual, the end of the year starts to fly by at an alarming rate. The students have done a great job with their final projects in telling the conservation of energy story through Rube Goldberg machines, calculations, and qualitative narration. This video is the trailer; full projects will be online next week.

153:180 Measurement of Ω

Students have been working with resistors, finding out how devices that use them can achieve different results: temperature adjustment, bright or dim lightbulbs, electrical circuit protection.  This also has allowed us to learn a different part of the multimeter.
