Teaching students to use the crosscutting concepts as a set of tools can empower them to direct their own scientific intellectual work.

Indeed. Students’ observations in daily living provide a very different perspective. They need opportunities to develop a sense of scale for the sun, earth, and stars by examining their sizes and distances from Earth.

@drloriandersen And yet for elementary kids, this is the opposite of what they observe. They think Earth is big and the sun is small. It takes multiple exposures to evidence to get them to change their thinking!
Our Sun is a huge, massive object, containing about 99.8% of all the matter in our Solar System. It has a mass of 2.192 · 10²⁷ tons, 333,000 times that of the Earth, and it converts 600 million tons of hydrogen into 596 million tons of helium every second https://t.co/kNws68k6Xi
Listening to Helen Quinn talk about the CCCs at the NSTA CCC Book Study webinar.

This could be a lot of fun at the elementary or middle school levels to explore the idea of causation vs. correlation.
Scientists look for patterns that can be causal, but we need to identify causal mechanisms or gather data to support causal explanations.

This keeps happening. How heavy are cats?
How are the crosscutting concepts related to each other?
This video explains each CCC and how they relate to each other.

Love this animation that shows the scale of celestial objects. Before you watch it, rank the planets, moon, and sun in order by size. Then watch.
After you watch it, did you learn something you didn’t know?

How many cross cutting concepts can you identify that will help explain this phenomenon?

A timelapse showing the incredible movement of a growing vine, exhibiting both nastic movement to find, and then a thigmotropic response to grasp and hold.

Love this graphic that demonstrates the #scale differences among different things. Coronavirus particles are so small that it is hard for people to understand. @ccc_thinking

What causes the motion we see?
What structure and function relationships are part of this phenomenon?
Does energy or matter movement explain this phenomenon?
How can we model this system, its components, and their interactions?
#CCCThinking
What patterns do you notice?
What is the time scale of the phenomenon?
What is stable and what changes? Is the phenomenon cyclical?

Patterns
Substances have patterns of properties, including index of refraction.
Index of refraction tells us how much light slows down in a material. Cooking oil and pyrex both have an index of refraction of 1.47.

Cause and effect
Filling the test tube with oil causes the test tube to "disappear".
What is the mechanism behind this?
We need to figure out why we see the test tube (or not).
