Scientists explain that the universe began in an extremely hot, dense state and has been expanding and changing over time.

Scientists discover that for an ideal gas at constant pressure, its volume increases in direct proportion to its absolute temperature.

Bonus Points!!!

Scientists find that the pressure of a fixed amount of gas increases when its volume decreases, as long as the temperature remains constant.

Scientists explain that matter is made of tiny particles called atoms and use this idea to explain many properties and behaviors of matter.

Scientists use evidence to explain that Earth's continents were once arranged differently and have moved because of the motion of tectonic plates.

Scientists observe that during an ordinary chemical reaction in a closed system, the total mass before the reaction equals the total mass after the reaction.

Scientists observe that energy can change from one form to another, but the total amount of energy in a closed system remains constant.

Bonus Points!!!

Scientists use a well-supported explanation to describe how Earth's Moon likely formed after a massive collision between early Earth and another large object.

Scientists explain that diseases can be caused by microorganisms that enter the body and reproduce.

Scientists explain that Earth's outer surface is divided into large plates that move slowly and cause earthquakes, volcanoes, and mountain formation.
