SNOLAB is Canada’s deep underground research laboratory, located in Vale’s Creighton mine near Sudbury, Ontario Canada.
It provides an ideal low background environment for the study of extremely rare physical interactions. SNOLAB’s science program focuses on astroparticle physics, specifically neutrino and dark matter studies, though its unique location is also well-suited to biology and geology experiments. SNOLAB facilitates world-class research, trains highly qualified personnel, and inspires the next generation of scientists.
At 2km, SNOLAB is the deepest cleanest lab in the world. It is an expansion of the facilities constructed for the Sudbury Neutrino Observatory (SNO) solar neutrino experiment and has 5,000 m2 of clean space underground for experiments and supporting infrastructure. A staff of over 100 support the science, providing business processes, engineering design, construction, installation, technical support, and operations. SNOLAB research scientists provide expert and local support to the experiments and undertake research in their own right as members of experimental collaborations.
Posted onMay 30, 2021|Comments Off on States of Matter Mini Lab: How does salt alter the freezing point of Water?
Objectives:
Part 1:
Investigate the interactions of liquids and solids. Investigate changes of state.
Materials
Per Student or Group:
4-5 ice cubes salt in a salt shaker plate or tray to work on (not paper!)
Key Questions
Why do the ice cubes stop slipping off when you add salt?
What To Do
1. Try to stack ice cubes into a tower. 2. Try again—but this time let the ice cubes sit out on a plate for 2–3 minutes. Then
sprinkle lots of salt on the top of each cube before putting the next one on top of it.
Extensions
Put a piece of string on an ice cube, then sprinkle it with salt. Wait a few moments, then lift the string. The water should melt then re-freeze, sticking the string to the ice cube.
