A greener procedure that you might consider to replace the traditional "formula of a hydrate lab" that has typically used copper II sulfate.

NGSS crosscutting concepts and core ideas are intended to be used as evidence to support explanations and arguments. I have found several lists of Chemistry core ideas online, but I don’t think I would give the ones I have seen to my students because they are either too long or written with language that I don’t think is suitable for novice learners of Chemistry. I have compiled a list of the crosscutting concepts and 12 core ideas for high school Chemistry that my students could use to support the explanations and arguments I will be asking them to write.

I attended a professional development session on the NGSS earlier this week by Brett Moulding and Nicole Paulson based on the book they wrote with Rodger Bybee, A Vision and Plan for Science Teaching and Learning. The authors propose the “gathering-reasoning-communicating” (GRC) structure as a simplified way of thinking about the Science and Engineering Practices. Reasoning is the keystone of the GRC structure and the primary thing we want science students to be doing. “Gathering” provides the raw materials for reasoning and “communicating” helps us know that reasoning has taken place.

Students can sometimes struggle to grasp gas behavior, as it’s much harder to visualize gases rather than readily available solutions, solids, or mixtures. Indeed, for many labs, if gas is a product, we’re often relegated to using balloons or gas columns to capture and measure the gases produced by reactions, which can be tricky or expensive. So this year, I tried something a little different when starting my intro chemistry students’ gas laws unit, and was very happy with the results.

Having had positive experience using Argument Driven Inquiry (ADI), I decided to try and adapt a specific heat lab to the ADI process.

In my class, I use the illustration of a mountain to help students push through the challenges of chemistry. Stoichiometry is the top of chemistry mountain. As we progress through the year, I say things like “the mountain is getting steep here!” or “there is not a lot of oxygen up here!” or “I will carry you up chemistry mountain if I have to!” to keep students motivated. When students finally get to the top of chemistry mountain (mid quarter 3), the air is thin, they are tired and they are ready to base jump off the mountain (see illustration from a former student below).

With a desire to increase curiosity and enthusiasm in my classroom along with ideas gleaned from Twitter, I have shifted my curriculum to a lab-first approach.

As a secondary science teacher, I have contact with my students everyday. Making relationships and learning about all of my students is key to letting them know that I am invested in their success.

The American Chemical Society is offering a new service in hopes of making science more accessible to the public. Each week they issue a short collection of science articles, written in an interesting and engaging style, that you might use with your students to help them make connections between the curriculum and their own lives. The service is called Discoveries!, and it is free.
