SC.912.L.18.12

In this lesson, students will run a variety of tests on different liquids. During their experimentation, students will collect data, graph data, collaborate and discuss their findings, compare their findings to known characteristics of water, make a claim, provide evidence and justification to support their claim, and create an advisory report of their findings. Students will run various tests on several different liquids and compare those characteristic to those of water. Students will gain an understanding that water is unlike other liquids in the way that it moderates temperature, in its cohesive strength, in its ability to expand upon freezing, in its pH neutrality, and in its designation as the "universal solvent."

Type: Lesson Plan

The lesson is an activity introducing the versatility of water as a solvent. Students will initially predict the solubility of a substance by matching the substance with an appropriate solvent. Then the concepts involved in solubility, ionic compounds versus covalent compounds, and polar compounds versus non-polar compounds will be presented. Students will have an opportunity to present and discuss the reasoning behind making their selection of a solvent for a particular solute.

Type: Lesson Plan

The importance of knowing what drinking water contains. How to know what properties are present in different bottled water. Knowing the elements present in water that is advantageous to growth and development of many things in the body. To know what to be alert for in water and to understand the importance of water in general.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

The goal of this lesson is that students will be able to conduct mini-experiments that demonstrate how water behaves. Students will perform the experiment, collect the data, diagram results, and generate a definition of the seven properties of water.

Water is both essential and unique. Many of its particular qualities stem from the fact that it consists of two hydrogen atoms and one oxygen, therefore creating an unequal sharing of electrons. From fish in frozen lakes to ice floating on water, Christina Kleinberg describes the effects of polarity.

Paul Anderson begins with a brief description of NASA discoveries related to Mars, Mercury and water. He then explains why water is required for life. He finally uses a simulation to show you why water acts as a wonderful solvent and provides a medium for metabolism.

Mr. Andersen explains why water is a polar molecule. He also explains why this gives water properties like cohesion, high specific heat, less dense ice, and the ability to act as a solvent. All of these properties are due to hydrogen bonding.
