Using the Combining Test to Identify Unknown Liquids
Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water.
Curated OER
Unknown Liquids
Students must design and conduct an experiment to determine which unknown liquid has a greater density based on basic information about the liquids and containers. Students are given specific materials to work with.
Curated OER
Bats and Hot Dogs
Students identify patterns and relationships from data that is collected and solve variables. In this investigative lesson plan students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.
