Representing Molecules

magnetic ping pong model kits

A quick search on Amazon for a package of 144 ping pong balls and a trip to the arts and crafts store for paint, magnets, and glue and I was ready to start making my own class set of model kits.

Puddles, Dissolving and a Cool Conductivity Tester...

Conductivity Tester

One of my biggest struggles with students is to try to explain what happens when items, specific inorganic salts, dissolve in water. It might sound simple to me and you. Research shows that students have many real misconceptions when it comes to explaining inorganic salts dissolving in water. My own experience along with other teachers I know is that we are amazed and sometimes frustrated with trying to help students understand the simple process of dissolving, especially with ions. A key piece of equipment is a good conductivity tester. Just got done making a stack of them and can't wait to have students try them. But back to "dissolving"....

NO MORE UNIT TESTS...What do you think?

My students are bright and motivated. Most work hard and prepare for class and tests. They perform extremely well on district-wide tests and my own classroom tests. However, I see real weaknesses on cumulative assessments requiring high levels of application. My students simply do not retain the content knowledge. I want to restructure my course to exclude "unit tests" and include only cumulative assessments. I'll share my early ideas here, and I would love to hear your experiences.

Punk Rock, Longboards and Mad Science

Longboard and Gas Laws

It all started with a class my son and I took together at Marc Adams School of Woodworking (link is external). To make a long story short, we started on a Saturday morning with nothing and left Sunday afternoon with a custom built longboard. (Think skateboard but...well...longer).
