The first chapter of every middle and high school science textbook I have ever seen contains an oversimplified section on “the scientific method.” I wanted my students to gain an understanding of science by doing science, as best as we can replicate in a classroom, though inquiry labs, class discussions, and defending claims with evidence.
The research says the best way to make your school better is to encourage teachers to participate in professional learning teams that unpack the standards to determine what each student should learn and how the learning will be measured, build a useful warehouse of evidence that learning is occurring, and critically review data collected to determine useful instructional strategies versus ineffective strategies.
The Board of Publication of the ACS Division of Chemical Education announces the opening of a search for the ninth Editor-in-Chief of the Journal of Chemical Education (JCE). A video and other documents are provided to outline the job posting, responsibilities of the position, the routine workings of JChemEd and characteristics of a well-suited candidate.
When I first started teaching I was very fortunate that a local teacher invited me to a high school chemistry teachers meeting. I was really young and really motivated to be a better teacher. I registered immediately and went to an all day event. I think I learned more that day than I did in all of my teacher training.
If you are looking for a measuring and density activity that will be challenging, allow students to experience success early on and can be boxed up to use again, you might consider trying the activity that I am sharing in this post.
I want to share a measuring activity for you to consider. First, start with two baseballs. The first baseball is a regular baseball. The other baseball is called a "small ball". Next, get six to eight students to volunteer. Without talking at all the students must hold the normal baseball and the small ball. They then must decide if the normal ball has more, less or the same mass as the small ball.
The Teacher Page includes all of the notes I need to set up, run, and clean up the particular experiment. I record from whom I obtained the lab. I list the location of chemicals in the stockroom. I've added what does and does not work, so that I don't have to remember it from year to year. I have notes of things to try in the future. The most important part, however, is the giant spreadsheet to calculate amounts of chemicals needed to make multiple volumes of solutions. This saves so much time and repeated effort!
It all started with a couple of summers spent on fellowships at the Institute for Chemical Education at the University of Wisconsin: Madison. In 1990 after two years of teaching high school chemistry I transferred to help open a school to specialize in Health and Medical education. I was 23 years old and ready to take on the world. The school’s student body was high poverty, 96% of the students qualified for the federal lunch program, and almost the entire student body was classified as minority. It was a good first year.
