In this supercool lesson we will use liquid nitrogen to show how solids, liquids and gases are affected by extreme changes in temperature. Students will observe the relationship between temperature and volume for each state of matter, and see various substances transition from one state to another. We will explore the differences between physical and chemical change, shrink balloons down by 700 times (and grow them back again!), and use chemistry to both extinguish a flame, and reignite one.

Recommended Audience – 5th
This is an assembly program recommended for up to 200 students per session in a large space. Each session is about 60 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 room in front of and behind the table for the instructor to walk. The instructor will need access to a sink during setup, breakdown and in between sessions. The sink does not need to be in the presentation space. 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.
This program can be combined with other assembly programs. Our Combination Pricing Options
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 $0.95 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.
Maximum of 3 sessions in a day. 60 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.
