NASA’s BEST Students: K – Grade 2
Launch Your Satellite
Use the engineering design process to construct and test a launch system to deliver a satellite into moon's orbit.
K-2 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.
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
PRE-ACTIVITY SET-UP
The fishing line apparatus should be at least 5 meters in length. Clamp or tie one end at table or chair height and stretch the line across the space to another table/ chair at the same level. Holding the free end of the line taut for each trial enables easy restringing of the successive balloon rockets. The line must be very taut for best results. Shoot the rockets toward the tied end. Two fishing line set-ups should be sufficient for a group of 20 students. Note: If the opening in the balloons tends to stick, try putting a little hand lotion inside the opening.
SET THE STAGE
- 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 set up to launch your satellite?” Remind students that one end of the set up is the launch pad and the other end is the Moon.
- Remind students to ask questions and brainstorm, then break into teams to create a drawing. All drawings should be approved before building.
CREATE
Challenge the teams to build their rockets based on their plans and remind them to keep within specifications. They will also need to attach their satellites from the previous session.
EXPERIMENT
Send each team to their assigned launch sites to test their rockets, completing the data tables as they conduct each trial launch.
IMPROVE
- After their first set of trials, allow teams to make adjustments to their rockets.
- Teams re-launch satellites and record launch distance.
- Teams should then 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?
- Which straw length did you choose and why did you choose it?
- If you had more time, what other rocket element would you change (ex: balloon shape or size)?
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?
