NASA’s BEST Students: Grades 6-8

Launch Your Satellite

Use the engineering design process to construct and test a launch system to deliver a satellite into moon's orbit.

Middle school learners will be guided through a series of challenges that follow the engineering design cycle. Join NASA on an adventure through solving an engineering challenge to launch your satellite design.

OBJECTIVE
To demonstrate an understanding of the Engineering Design Process while utilizing each stage to successfully complete a team challenge.

DESIGN CHALLENGE
To design a balloon rocket to launch the satellite that was built in the last activity. The goal is to get the satellite to go as far as possible.

PROCESS SKILLS
Observing, communicating, measuring, collecting data, inferring, predicting, making models

MATERIALS

  • Satellite model from previous activity
  • General building supplies
  • Rulers or meter sticks
  • Binder clips or clothes pins
  • Balloons (several per group)
  • Straws
  • 5-meter fishing line set-up strung between two tables

STUDENT PAGES

  • Design Challenge
  • Ask, Imagine and Plan
  • Experiment and Record
  • Quality Assurance Form
  • Fun with Engineering at Home

MOTIVATE

SET THE STAGE

ASK, IMAGINE, AND PLAN

  • Share the Design Challenge with the students and ask students to retrieve their satellites from last session.
  • Demonstrate how a balloon rocket works by sending a balloon connected to a straw up the fishing line. Do not model how best to attach the satellite or how best to power the rocket, other than releasing the air by using your fingers.
  • Ask the students, “How can we use this setup to launch your satellite?” Remind students that one end of the line is the launch pad and the other end is the Moon.
  • Have students take the time to imagine a solution for a balloon rocket design and then draw their ideas. All drawings should be approved before building begins.

CREATE

  • Challenge the teams to build their rockets based on their plans. In addition, teams will need to design a system to attach their satellites to the launch set up. Remind students to keep within specifications.

EXPERIMENT

  • Send teams to their assigned launch sites to test their rockets, completing the data table as they conduct each trial launch.

IMPROVE

  • After the first set of trials, allow teams to make adjustments to their rockets.
  • Teams re-launch satellites and record their data.
  • Teams discuss how far their rocket traveled and which combination of variables gave the best results.

CHALLENGE CLOSURE

Engage the students in the following questions:

  • What was the greatest challenge for your team today?
  • Why is the balloon forced along the string?
  • How did changing the straw length/number of balloons affect how far the rocket travelled on the fishing line?

PREVIEWING NEXT SESSION

Ask teams to think about how humans navigate robotic rovers on a distant planet or moon. How are they programmed? How do the rovers receive messages from a team on Earth?
