# Engineering Estes Rockets Level 2 - Unit Plan

Grade 9-12 – 10 (45 min) classes

### Topics Covered

Engineering Design Process | Rocket Stability | Impacts of Rocket Design on Altitude

### Essential Question

How is the altitude attained by a model rocket affected by the dimensions of the body tube, its mass distribution, and its fin configuration?

### Overview

In this unit, students will answer the question, How is the altitude attained by a model rocket affected by the dimensions of the body tube, its mass distribution, and its fin configuration?

Estes recently announced a student competition for the design and build of a model rocket that can reach the highest altitude using parts found in the Designer’s Special kit. As part of the competition, students will make a video commercial introducing their rocket design and launch results to the judges.

This model rocket project will be focused on predicting and designing for stability while trying to reach a maximum altitude. Students will explore different factors that affect stability - geometry, mass distribution, and fin shape and configuration. In their commercial, students will communicate to the judges how they came up with their design and show the results of their launch.

### HS-ETS 1-2

Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.

### HS-PS 2-1

Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.

### SEPs

• Planning and carrying out investigations
• Analyzing and interpreting data
• Using mathematics
• Obtaining, evaluating, and communicating information

### CCCs

• Structure and function
• Stability and change

### WHST.9-12.7

Conduct short as well as more sustained research projects to answer a question (including a self-generated question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on the subject, demonstrating understanding of the subject under investigation

### SL.11-12.5

Make strategic use of digital media (e.g., textual, graphical, audio, visual, and interactive elements) in presentations to enhance understanding of findings, reasoning, and evidence and to add interest.

### MP.2

Reason abstractly and quantitatively.

### MP.4

Model with mathematics.

### HSN-Q.A.1

Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.

### Air Resistance

The force resulting from air creating friction on an object, magnitude dependent on surface area

### Altimeter

A device that can measure its height from a zero ground position

### Apogee

The peak altitude of a model rocket

### Assembly

A set of parts put together in a purposeful way or according to design

### Body Tube

The portion of a rocket that houses most of the parts

### Center of Gravity

The point on an object where the weight on either side is balanced with the other

### Center of Pressure

The point on an object where the air flow from all directions is balanced

### Drag

The force that opposes motion due to various factors including air resistance

### Engine (model rocket)

A miniature non-metallic solid fuel rocket motor that contains propellant and may contain a delay element and an ejection charge. Designed to impart force to accelerate the rocket during flight and to activate the recovery system at or near maximum altitude.

### Fins

Passive stabilizing and guiding unit of a model rocket; an aerodynamic surface projecting from the rocket body for the purpose of giving the rocket direction and stability.

### Force

A push/pull on an object resulting from interaction with another object, either with or without contact.

### Launch Lug

A round, hollow tube that slips over the launch rod to guide the model during the first few feet of flight until sufficient airspeed is reached to allow the fins to function.

### Launch System

Stable launching rod, remote starter system, and other components needed to launch a model rocket.

### Nose Cone

The forwardmost part of the rocket.

### Recovery system

A device incorporated into a model rocket for the purpose of returning it to the ground in a safe manner. Usually achieved by creating drag or lift to oppose the acceleration of gravity. All model rockets must employ a recovery system, such as a parachute.

Non-flammable paper that protects the recovery system from melting the parachute when the ejection charge occurs.

### Stability

An object or system that is in the state of minimal unbalanced forces

### Velocity

The speed of an object in a specified direction
