In Mosa Mack’s Gravity unit, students are led through a progression of three inquiry lessons that focus on the gravitational force that pulls objects down toward the Earth. *Unit focuses on conceptual physics, not mathematical representations.
Students observe a mysterious phenomenon in one of Mosa’s vacation videos: a ball rolling uphill! Convinced that something isn’t quite right, Mosa and her friends embark on a mission to solve the mystery of the anti-gravity hill. (75 mins)
Students explore gravity in a variety of contexts through a series of hands-on stations. (100 mins)
Civilians in a war-torn country are in desperate need of food and supplies. Students use what they have learned about gravity and its corresponding factors to design and model a solution that safely drops food and supplies to its destination. (200 mins)
* To give our users the most comprehensive science resource, Mosa Mack is piloting a partnership with RocketLit, a provider of leveled science articles.
This article explains how gravity works to pull planets and stars together into spheres.
Why doesn't the Earth fall into the Sun? In this article, we define the terms mass, gravity, orbit, and velocity. This article serves to introduce students to the ideas behind why planets are able to stay in orbit by flying through space at just the right velocity, and with just the right amount of gravitational pull from their star.
In this article, students read about the different ways that gravity changes the landscape through creep, mass wasting, landslides, or rockfall.
In this article, we look at the way that potential energy is stored in objects that are farther away from the ground. Using the example of a of roller coaster, we define the word "system" and talk about the benefits of using a model to look at the relationship between potential energy and distance
