In this section, the goal is to introduce students to properties of water. However, you may choose to skip it if you feel your students are not cognitively ready. Due to the abstract nature of the water molecule and bonding, students will need a great deal of scaffolding to come to a conceptual understanding of the water molecule and its properties.
Approaches to support students in their learning may include exposing them to several different representations, from 2-D schematic drawings and animations to 3-D physical models and the human simulation described in Background Information for Teachers. Students should then be able to construct an understanding of the properties of the water molecule, which you can assess in a number of ways. For example, you could have students create their own drawings or build their own 3-D models alone or collaboratively with labels and explanations. The resources in this section focus on the 2-D images and animations.
This color animation of water molecules interacting and forming hydrogen bonds is a hybrid between a PowerPoint slide show and an animation. Students can replay portions or click next if they do not need to replay a segment. MSP full record
