The Motion Of Molecules In Water

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.  

Sometimes things can be hidden in plain sight. Assist your young biologists as they explore the hidden lives of microorganisms surviving in water. Pupils bring samples of water to class and view these under the microscope to witness the...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

I heard that oxygen and magnesium were going out and I was like "O Mg."  Pupils experiment with adding food coloring to water of various temperatures in order to determine how temperature impacts molecular movement. This is the...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

A water strider is a bug that taps into the attraction between the positive and negative ends of water, allowing the bug to walk on water. Learners view short videos showing polar characteristics of water. Pairs then discuss what polar...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice to...

Explore the water cycle in an interactive diagram of the process. The diagram shows how water is a moving system and constantly changing forms. The resourc includes vocabulary words that pupils click on in order to discover more about...
