Learn about real space flight and Newton's laws of motion with this fun lesson! This new twist on a classic project lets your students build a multi-stage balloon rocket that they can launch across the classroom.
MS-PS2-2. 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.
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.
This lesson focuses on these aspects of NGSS Three Dimensional Learning:
Science & Engineering Practices
Disciplinary Core Ideas
Asking Questions and Defining Problems. Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim.
Analyzing and Interpreting Data. Analyze and interpret data to determine similarities and differences in findings.
PS2.A: Forces and Motion. The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.
ETS1.B: Developing Possible Solutions. Sometimes parts of different solutions can be combined to create a solution that is better than any of its predecessors.
Cause and Effect. Cause and effect relationships may be used to predict phenomena in natural or designed systems.
Patterns. Graphs, charts, and images can be used to identify patterns in data.
