The Calvin Cycle or the light-independent (dark) reactions of photosynthesis.
Introduction to cellular respiration, glycolysis, the Kreb's Cycle, and the electron transport chain.
Clarifying some points on evolution and intelligent design.
Basics of gravity and the Law of Universal Gravitation.
Learn about Newton's third law of motion, which states that for every action there is an equal and opposite reaction. Look at multiple examples that illustrate this law, including pushing a block on ice, pushing against a desk, walking on sand, how rockets work, and how an astronaut could save themselves from drifting in space.
Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration.
Applying Newton's first law to answer some true/false statements about why objects move (or not).
Basic primer on Newton's First Law of motion.
Understanding why distance is area under velocity-time line.
Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity.
