2 Class Periods
In this 2 part class, students will learn concepts of force, momentum, gravity, and vectors (i.e. Newton’s laws) and explore speed and velocity. The hands-on class project consists of making rockets out of 2-liter bottles. These rockets will be launched using compressed air and water. Students will also learn triangulation, which will enable the students to measure the height of the flight of their rockets.
Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
Support an argument that the gravitational force exerted by Earth on objects is directed down.
NGSS MS ETS1-3:
Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
