Science and Math: Working to Connect NGSS and CCSS

Posted: Tuesday, September 2nd, 2014

by Peter A’Hearn

All science people know that there is a strong connection between science and math, so finding the connections between the Next Generation Science Standards and the Common Core Math Standards should be a no brainer. Last year, Palm Springs USD conducted a dozen Science/Math lesson studies to explore the connections. We found many strong connections and also identified some challenges in putting the two sets of standards together.

The math and science teachers used a modified version of the K-12 Alliance TLC lesson study to plan their lessons. There were two teams from grades 6, 7, and 8, and teams for Earth Science/Algebra, Biology/Geometry, and Chemistry/Algebra II. Some of the lessons clicked perfectly, some failed awkwardly, and many lessons were learned about the challenges of implementing NGSS and the Math Common Core Standards.

One of the Biology/Geometry teams focused on data analysis (part of Geometry in the CCSS). They decided to do a science lesson based on HS-LS4-3:

In a pre-lesson, the class acted as predators of two kinds of beans in a cup. When they chose beans without looking they preferentially chose the larger kidney beans over smaller pinto beans. The lesson began with a discussion of the class data:  AHearn_Image1

Students made predictions and then graphed the data to find a best-fit line to generate a prediction for when the kidney bean population would go extinct.

Once students had practiced with this self-generated data, they were given real world data on local populations of mesquite trees.


Students graphed the data and made a prediction about the year when there would no longer be a mesquite-based ecosystem along the San Andreas Fault in Desert Hot Springs, CA.

Lessons Learned – The NGSS standard is really about natural selection, but the real world data we used wasn’t really comparing two competing populations. The NGSS is asking students to interact with real world data sets. We couldn’t find any readily accessible real world data about advantageous vs. disadvantageous traits. The data is out there but much of it isn’t in student and teacher ready to use formats. (Thanks to KD Fleming from the UCR Center for Conservation Biology for the Mesquite Data!) (P.S. The reason for the drastic decline in Mesquite population is probably due to the declining water table due to groundwater pumping)

The 6th grade team decided to focus on the water cycle and real world data. They looked at data on the declining water level in Lake Mead using real time data. AHearn_Image4Based on the trends in the graph, students were asked to predict (based on evidence) what the blue curve would look like for the rest of 2014.

Lessons learned – Most 6th graders have a very hard time using evidence to make a prediction. Many predicted that people would start saving water or that there would be huge rainstorms and had curves that went up ignoring the pattern in the data. Some believed that their graphs had to stay within the boundaries of the page and so couldn’t follow the downward trend of the past two years. Both the Common Core and the NGSS place a strong emphasis on the use of evidence. We learned through the lesson studies we conducted that teachers will have hard work to do to help our students to learn to follow the evidence instead of their opinions and hopes.Teachers need to work hard to find the right questions to ask to help kids look at evidence. They also need to work on helping kids understand what kinds of evidence count in math and science.

By the way – here’s what really happened: AHearn_Image5

Scary huh?

The Chemistry/Algebra II team had a hard time finding standards that provided a strong link between their subjects. They decided to use the change of pH of lemon juice at different concentrations as a model of a log function: AHearn_Image6


Lessons Learned – Probeware gave us some really nice results. There were some good discussions about how much to let kids struggle with figuring out how to do the dilutions. The biggest challenge was that to find a math alignment we had to create a lesson on acid-base chemistry, which doesn’t have an NGSS standard attached to it. Note that it is important to understand that the NGSS is understood as representing the floor, not the ceiling – this means that it is okay to go beyond the standard in teaching. We also decided that acid-base systems are a type of equilibrium system, which is an NGSS Standard.

Other teams created lessons on probability in genetics, graphs of motion, scaling craters on a map, and mathematically modeling the relationship between force, mass, and acceleration.

Trying to create common science and math performance tasks (and even science, math, ELA) presents its own set of opportunities and challenges. We are trying to do this so students spend fewer days testing and so that we can make the connections between the subjects apparent. In the 6th grade teachers in our district teach both math and science, so developing common assessments makes sense.



The challenge is to really understand what both the Common Core and the NGSS are asking for and then find the commonalities. We have discovered that the NGSS assessment boundaries sometimes need to be crossed to bring the math up to grade level. For example this middle school energy standard:

“Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.” (MS-PS3-5)

… comes with this assessment boundary:

“Assessment Boundary: Assessment does not include calculations of energy.”

However, to make a common math/science assessment we do need the students to multiply decimals, which means calories of heat transferred. The key in designing an assessment is to have students show that they understand heat flow in non-mathematical ways as well so they aren’t just memorizing a procedure to get the answer.

The connections between the NGSS and the Math Common Core are strong and we can do great things for our students by working closely with our math colleagues. There will also be hard work and frustration as we try to fit our two sets of standards and two ways of looking at math together.

Find Your Reason to Engage

Posted: Monday, January 15th, 2018

by Jill Grace

I was recently reflecting on events in the news and remembered that several years ago, National Public Radio had a story about a man named Stéphane Hessel, a World War II French resistance fighter, Nazi concentration camp survivor, and contributor to the United Nation’s Universal Declaration of Human Rights. The story focused on a book he had published, Time for Outrage (2010).

In it, Hessel makes the argument that the worst attitude is indifference:

“Who is in charge; who are the decision makers? It’s not always easy to discern. We’re not dealing with a small elite anymore, whose actions we can clearly identify. We are dealing with a vast, interdependent world that is interconnected in unprecedented ways. But there are unbearable things all around us. You have to look for them; search carefully. Open your eyes and you will see. This is what I tell young people: If you spend a little time searching, you will find your reasons to engage. The worst attitude is indifference. ‘There’s nothing I can do; I get by’ – adopting this mindset will deprive you of one of the fundamental qualities of being human: outrage.  Our capacity for protest is indispensable, as is our freedom to engage.”

His words make me take pause when I think of the status of science in the United States. A general “mistrust” of science is increasingly pervasive, as outlined in a New Yorker article from the summer of 2016. Learn More…
