Using Interactive Tools to Assist High School Students with Difficult Concepts

Posted: Saturday, January 1st, 2011

by Heather A. Marshall

I recently found a website that offers free interactive simulations for teacher use focusing on science topics.  This website:, through the University of Colorado at Boulder, has the sims available for free download.  You can browse by category, by new sims, or by grade level.  They are sponsored by NSF, the William and Flora Hewlett Foundation, and others.  The PhET program is interested in providing research-based simulations of physical phenomena for free to teachers.  These simulations can help students visualize some of the concepts we teach in high school in an engaging way, and help students grasp difficult concepts.  PhET hopes that teachers will use these sims within lectures, as extensions of classroom activities, integrated into homework assignments, and as additions to more traditional laboratory experiments.

One of the simulations is for glaciers.  It allows the user (student) to adjust sea-level and air temperatures and observe the effects on glacier growth and retreat.  It also allows students to measure the thickness of the glacier, create multiple fractures with a drill and observe how the fractures move and stretch through the glacier, and other nifty tools.  The advanced feature allows students to view graphs associated with the data.  Another simulation is for the greenhouse effect, allowing the user to see the differences in temperatures with more or less greenhouse gases, observe photon interactions, and even model the greenhouse effect using glass plates.  Simulations include: Natural Selection, Gravity Force, Buoyancy, a Radioactive Dating Game, and many more.

Another big find of the new year is an interactive flashcard set with terms for a high school earth science class.  The flashcards can be shuffled or not and cover the introductory topics in an earth science class (such as chemical structure, minerals and rocks).  The cards can be manipulated online, printed, downloaded, added to, and more.  The earth science cards are posted here:, and you can even create your own set by clicking the Create Flashcard button on the right-hand side of the screen.  Looks like an excellent tool to share with students or use as a classroom tool for test reviews.  The ProProfs Flashcard site also has links to an online quiz maker, online brain games, and even SAT preparatory tools.

I use another online site for online testing:  For $25.00 a year, I can generate and save all of my unit tests and administer them online (in a computer lab or at home) for all of my 180 students.  It automatically grades the tests for me, and does a great item analysis breakdown.  You create your own standards, so you can completely align the test to your course.  The first test I gave on ClassMarker saved me hours in grading and analysis time.  I have found that short answer tests are incredibly difficult to do, however.  This works best with multiple choice or matching type questions.  I am currently looking for better options to be able to administer online tests with greater variety but still able to do the item analysis.  If you have ideas, please email me and I will gladly report on them here!

CSTA Is Now Accepting Nominations for Board Members

Posted: Friday, November 17th, 2017

Current, incoming, and outgoing CSTA Board of Directors at June 3, 2017 meeting.

Updated 7:25 pm, Nov. 17, 2017

It’s that time of year when CSTA is looking for dedicated and qualified persons to fill the upcoming vacancies on its Board of Directors. This opportunity allows you to help shape the policy and determine the path that the Board will take in the new year. There are time and energy commitments, but that is far outweighed by the personal satisfaction of knowing that you are an integral part of an outstanding professional educational organization, dedicated to the support and guidance of California’s science teachers. You will also have the opportunity to help CSTA review and support legislation that benefits good science teaching and teachers.

Right now is an exciting time to be involved at the state level in the California Science Teachers Association. The CSTA Board of Directors is currently involved in implementing the Next Generations Science Standards and its strategic plan. If you are interested in serving on the CSTA Board of Directors, now is the time to submit your name for consideration. Learn More…

State Schools Chief Tom Torlakson Announces 2017 Finalists for Presidential Awards for Excellence in Mathematics and Science Teaching

Posted: Wednesday, September 20th, 2017

SACRAMENTO—State Superintendent of Public Instruction Tom Torlakson today nominated eight exceptional secondary mathematics and science teachers as California finalists for the 2017 Presidential Awards for Excellence in Mathematics and Science Teaching (PAEMST).

“These teachers are dedicated and accomplished individuals whose innovative teaching styles prepare our students for 21st century careers and college and develop them into the designers and inventors of the future,” Torlakson said. “They rank among the finest in their profession and also serve as wonderful mentors and role models.”

The California Department of Education (CDE) partners annually with the California Science Teachers Association and the California Mathematics Council to recruit and select nominees for the PAEMST program—the highest recognition in the nation for a mathematics or science teacher. The Science Finalists will be recognized at the CSTA Awards Luncheon on Saturday, October 14, 2017. Learn More…

Thriving in a Time of Change

Posted: Wednesday, September 13th, 2017

by Jill Grace

By the time this message is posted online, most schools across California will have been in session for at least a month (if not longer, and hat tip to that bunch!). Long enough to get a good sense of who the kids in your classroom are and to get into that groove and momentum of the daily flow of teaching. It’s also very likely that for many of you who weren’t a part of a large grant initiative or in a district that set wheels in motion sooner, this is the first year you will really try to shift instruction to align to the Next Generation Science Standards (NGSS). I’m not going to lie to you, it’s a challenging year – change is hard. Change is even harder when there’s not a playbook to go by.  But as someone who has had the very great privilege of walking alongside teachers going through that change for the past two years and being able to glimpse at what this looks like for different demographics across that state, there are three things I hope you will hold on to. These are things I have come to learn will overshadow the challenge: a growth mindset will get you far, one is a very powerful number, and it’s about the kids. Learn More…

If You Are Not Teaching Science Then You Are Not Teaching Common Core

“Science and Social Studies can be taught for the last half hour of the day on Fridays”

– Elementary school principal

Anyone concerned with the teaching of science in elementary school is keenly aware of the problem of time. Kids need to learn to read, and learning to read takes time, nobody disputes that. So Common Core ELA can seem like the enemy of science. This was a big concern to me as I started looking at the curriculum that my district had adopted for Common Core ELA. I’ve been through those years where teachers are learning a new curriculum, and know first-hand how a new curriculum can become the focus of attention- sucking all the air out of the room.

Tools for Creating NGSS Standards Based Lessons

Posted: Tuesday, August 29th, 2017

by Elizabeth Cooke

Think back on your own experiences with learning science in school. Were you required to memorize disjointed facts without understanding the concepts?

Science Education Background

In the past, science education focused on rote memorization and learning disjointed ideas. Elementary and secondary students in today’s science classes are fortunate now that science instruction has shifted from students demonstrating what they know to students demonstrating how they are able to apply their knowledge. Science education that reflects the Next Generation Science Standards challenges students to conduct investigations. As students explore phenomena and discrepant events they engage in academic discourse guided by focus questions from their teachers or student generated questions of that arise from analyzing data and creating and revising models that explain natural phenomena.
