Next Generation Science Standards For this Lesson

Next Generation Science Standards Performance Expectations for This Lesson

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.

Next Generation Science Standards Practices, Core Ideas and Crosscutting Concepts

Planning and Carrying Out Investigations

• Conduct an investigation and evaluate the experimental design to produce data to serve as the basis for evidence that can meet the goals of the investigation.

• Apply scientific ideas or principles to design an object, tool, process or system.

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 force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.

Stability and Change

Explanations of

stability and change

in natural or designed

systems can be

constructed by

examining the

changes over time

and forces at different

scales.

Next Generation Science Standards Connections to Other DCI’s in Middle School

PS3.A: Definitions of Energy

Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. A system of objects may also contain stored (potential) energy, depending on their relative positions.

PS3.B: Energy Transfer

When the motion energy of an object changes, there is inevitably some other change in energy at the same time.

PS3.C: Relationship Between Energy and Forces

When two objects interact, each one exerts a force on the other that can cause energy to be transferred to or from the object.

Let’s Pause for Questions

Please type your questions in the chat!

The Engineering Design Process

What is an Engineering Design?

A. A way for you to be creative

B. Practical applications to real-world problems

C. A process for learning beyond the traditional “textbook”

NASA Now: Propulsion

Suggestions?

Thrust Structures

What are some ways NASA

engineers could make a launch

vehicle as lightweight as possible?

The Challenge:

Build the lightest weight thrust structure that

will withstand the force of launch to orbit at

least three times.

Testing Student Designs

Launch to orbit = 1 meter

Importance of

efficiency

The appeal of Spacecraft Structures

• Easy to navigate

• Supports content standards

• Background, resources, and masters

Modifications

and

Extensions

Modifications

• Allow modifications using cardboard

• Allow mid-test repairs

• Change the rocket mass

• Design with alternative materials

• Limit designs by cost (budget)

If it costs $10,000 to lift a pound

(half a kilogram) of payload into

orbit, calculate the cost of sending

yourself into space.
