Sea Water Freeze

Sea ice contains 17 sub-types based on age and various characteristics. Scholars observe ice floating in a simulated ocean and record their observations. Then, they view photographs of different types of sea ice and learn to...

Many arctic mammals, such as polar bears, seals, and walruses, depend on the sea ice about 3 m thick for their habitat. Pupils investigate the properties of polar water and polar ice and their properties through readings, videos, and...

Students explain how melting glaciers affect global warming. In this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Explore the world (our world) of melting ice caps. Why are these caps melting? What is the effect of melting ice caps? Dive into the ever-present issue of global warming with a resource that has learners looking at data and participating...

Students work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.

Students conduct experiments using water. In this properties of fresh and sea water lesson, students investigate boiling point, freezing point, and the water's retention of heat.  Students hypothesize, collect and record data, and draw...

Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

Students conduct an experiment.  For this salinity lesson, students learn about sea ice, why it is important and how changing amounts can affect the sea.  Students conduct an experiment to find out the effects of salinity on the...

Using different types of water, earth science explorers set out to prove the ocean's ability to absorb greenhouse gases. They shake, heat, and freeze the water samples to examine gas content. This lesson is useful during a unit...

Students explore what type of solutions freeze. They design their own experiments to compare how fresh water and salt water freezes. In addition, they write their observations in a journal and complete analysis questions.
