Question

1. which is a \big idea\ for matter and change?

the laws of nature have all been discovered.
forces cause changes in motion.
atoms are the building blocks of all things.
the universe is very old and very large.

Explanation:

Matter is made up of atoms. Atoms combine in various ways to form different substances. This is a fundamental concept in understanding matter and its changes. The statement "Atoms are the building blocks of all things" directly relates to the nature of matter. The other options: "The laws of nature have all been discovered" is incorrect as scientific exploration is ongoing. "Forces cause changes in motion" is more related to physics of motion (dynamics) rather than matter itself. "The universe is very old and very large" is about the universe's scale and age, not matter's composition.

Answer:

Atoms are the building blocks of all things.
