Sea Water Freeze
Middle schoolers observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
Curated OER
Sea Ice
Students observe the freezing times and temperatures of water with varying levels of salinity. They determine how icebergs form, how they act, and what they may be made of. They discover that salinity level affects the time it takes...

Salt Water vs. Fresh Water
Students explore why the oceans do not freeze. They explain why they think the Atlantic Ocean does not freeze. Students are given background information about what they are doing. They create a hypothesis about what they believe...
