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...

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.  

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...

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...

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. 

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...

Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the instructional activity and a...

Get to know H2O! It's the most popular molecule in the world, but how well do you know it, really? An interview-style video gets to the bottom of our common knowledge about water, asking random subjects for the formula and what the...

Using different types of water, earth science explorers set out to prove the ocean's ability to absorb greenhouse gases. They shake, heat, and freeze the water samples to examine gas content. This lesson is useful during a unit...

Water is common? Not really! Learn how the polarity of the water molecule gives it tremendous properties that make is quite unique in the universe. Learners will understand surface tension, adhesion, and cohesion, as well as why these...
