Students construct a simple refracting telescope. They calculate the magnification.

Students explore how telescopes work, build a model of their own, and consider how real telescopes can be used to ask-and help answer-questions about the universe.

Students investigate the force of gravity and how it effects different objects that are put into acceleration when applied the experiment of free falling. They drop different objects that have a variety of masses and some that cause air...

Put together the pieces and model a parabola. Learners work through several examples to develop an understanding of a parabola graphically and algebraically.
