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.

Recommended Audience – 2nd
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.
A space large enough to fit all attending students either seated on the floor or in chairs plus their teachers. In addition, there must be room for two 6’ long rectangular tables, set up at one side of the room with space behind and in front of the tables for the instructor to walk. The instructor will need access to a sink during setup and breakdown and between programs. The sink does not need to be in the presentation room. 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. A 3-pronged electrical outlet is needed near the presentation space. Let us know if a projection system is available in the space, or if we should bring our portable system to set up.
Outside Greenville county a travel fee of $0.95 per mile applies.

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.
