Student Exploration: Estimating Population Size Vocabulary: percent error, population, sample Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A jar contains 100 marbles total. Some are black. If you pull 4 marbles out and 1 is black, how many out of the 100 marbles would you guess are black? I would guess around 25. Explain. The reason I would guess 25 is because ¼ is the ratio of black marbles to other marbles being pulled out of 100 and ¼ of 100 is 25. 2. A ...

Student Exploration: Air Track Vocabulary: air track, approach velocity, conservation of energy, conservation of momentum, elasticity, kinetic energy, momentum, separation velocity, velocity Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Imagine going to a bowling alley with a bowling ball and a ping pong ball. 1. Why is a bowling ball better for knocking down pins than a ping pong ball? Because the mass of the bowling ball is greater than a ping pong ball resulting i...
