In this supercool lesson we will use liquid nitrogen to show how solids and liquids are affected by extreme changes in temperature. Students will observe how changes in temperature can affect the properties of materials and learn whether those changes are reversible or not.

This is an assembly program recommended for up to 100 students per session in a large space. Each session is about 45 minutes long and up to 3 sessions can be booked in a visit. This assembly can be combined with a different assembly. See our assembly combination options for details.
A space large enough to fit all attending students either seated on the floor or in chairs plus their teachers.
- Room for two 6’ long rectangular tables (or equivalent), set up at one side of the room with space behind and in front of the tables for the instructor to walk.
- A screen (projector and screen or digital screen) that the instructor can connect a laptop computer to. If this is not available, we can set up a portable projection system.
- Access to a sink during setup and breakdown and between programs. The sink does not need to be in the presentation room.
- A 3-pronged electrical outlet near the presentation space (if outlets are 2-pronged, let us know so we can plan for an adaptor)
Gyms, Cafeterias and auditoriums work well. Large classrooms, such as Music rooms, can also be used depending on the size of the audience and the room. For smaller groups a regular sized classroom may work. Due to the large amount of setup involved, this program cannot move from space to space once set up.
| 1 Session | $175 |

Outside Greenville county a travel fee of $1.00 per mile applies.

This program can travel up to 2.5 hours from Roper Mountain for a single day trip. Sites farther from Roper Mountain (up to 5 hours) can request an overnight visit. A flat $200 per night fee is added for each night to cover hotel and meals for our instructor. There is a travel fee of $1.00 per mile for all sites outside of Greenville county. We use Google Maps to calculate drive times and distances. It can be beneficial for more distant locations to team up with other sites in your area to combine trips and split travel fees.
Sessions are 45 minutes long. Maximum of 3 sessions in a day. 45 minutes is required for setup. 30 minutes is required for breakdown. 15 minutes is required to reset the program between sessions. If the programs extend through lunch time, a 30 minute or longer break between programs is requested so the instructor can eat lunch.
Greenville County schools: First session can start as early as 8:15 a.m.
Out of County Schools: Calculate the drive time from Roper Mountain Science Center to your school, then add that amount of time to 8:00 to determine your earliest assembly start time. If it is a one hour drive from Roper Mountain to your school, add one hour to 8 a.m. and the earliest start time is 9 a.m.
