Water Kit© Basic Lessons

Numerous lessons and activities are possible with 3D Molecular Design’s Water Kit©. First, you and your students will use the magnetic water molecules to explore the concepts of polarity and hydrogen bonding.


Water Kit© Osmosis Lesson

Living things must perform vital activities in order to maintain their existence, including moving water in and out of cells. It is important for your students to understand how water flows in and out of a cell through the membrane that surrounds cells, as it directly impact a cell’s ability to survive. The passive transport of water across a selectively permeable membrane is called osmosis.


Water Kit© pH Lesson

Your students will use the Water Kit© to create a physical representation of the autoionization of water, describe and produce a physical representation of the dissociation of a strong acid and a strong base, and associate a high hydronium ion concentration with low pH and a high hydroxide ion concentration with a high pH.


Water Kit© Water Run-Off Guided Activity

Your students will explore the process of erosion and pollution caused by water runoff, using the Water Kit, paper clips and a 3-ring binder.


Water Kit© Patterns In Crystal Structures

This activity, intended for grades 4-5, uses the magnetic water models and a guided-inquiry approach. It will help your students observe patterns and forms. Your students begin by identifying the number of hexagons in ice. Then they construct and compare cubic and hexagonal ice structures before creating a snowflake.


Water Kit© Ice and Snowflakes

Scientists have described 14 structures of ice, many of which can be constructed with one or more Water Kit© sets. Here are lessons for building cubic ice (Ice 1c), which is present in the upper atmosphere and requires 10 water molecules; hexagonal ice (Ice 1h), which falls as snowflakes and is formed with 12 water molecules; and more elaborate snowflakes, which can be created with additional Water Kit© sets.


Water Kit© Animations and Videos

Explore a variety of videos to help enhance your use of the Water Kit and classroom study of water.


Water Kit© Digital Student Modeling Activities

Students can build a water molecule, model the polar nature of water, demonstrate the three states of matter and answer thought questions.


Water Kit© Constructivist Lab

Middle and high school students working in small groups first use the unassembled pieces of the water molecules to investigate properties of, and interactions between, the model parts before assembling water molecules.

Teacher Tip

Keep your magnetic water molecules from evaporating by telling your students to make the hexagonal ice structure as their last activity. Once you finish exploring the concepts related to ice, your students can place the ice model next to the water cup with the ethane, hydroxyl group, sodium and chloride pieces. With a quick glance you will know all of the water molecules and other pieces are ready to go in the cup!
