You will use this hands-on activity to help elementary students learn about the engineering process while exploring rocketry. You will introduce students to Earth's orbits that house satellites LEO, MEO and GEO and discuss how satellites reach the desired orbit. Students will then work through the engineering process by modifying their rocket’s propellant to reach different desired launch altitudes.

To prepare for your classroom visit, about two weeks in advance, review the information in the Engineer Guide and the materials provided for this activity. Contact the teacher and provide them with the list of materials you need the class to gather for the hands-on experiment.

Additionally, ask the teacher to pre-select a launch area that will be available during your classroom visit. The launch area will require enough space for groups to launch side by side with a few feet between each group and with a clear space of at least 50 feet in front of the groups. An athletic field is ideal.
