Solubility

To conclude a mini unit on the dissolving of M&Ms® candy coating, this instructional activity investigates whether or not the concentration of sugar in the solvent affects the dissolving rate. Consider having older science learners...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-lesson unit on dissolving, this installment investigates the effect of temperature. If you consult the...

Make sure to consult the teacher's handbook, Inquiry in Action - Investigating Matter Through Inquiry, for two demonstrations that can be done to introduce solubility and measuring crystal mass before having the class conduct this...

Is sugar more soluble than salt? Experiment with water and solubility with an elementary science activity. After interpreting data from a bar chart, fifth graders use different types of sugar to determine if the size of sugar particles...

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

Students investigate factors affecting the rate of solubility. In this rate of solubility lesson plan, students experiment by crushing, heating and cooling solutes and solvents to see how the solubility is affected. For each situation,...

Mixtures and solutions are different; one can be separated fairly easily and the other cannot. This hands-on experiment was written specifically for learners with visual impairments or blindness. They will use lemonade and trail mix to...

Have you ever mixed together salt and pepper? Isn't it fun to see how all of those tiny grains of salt and pepper mix together. But what if you had to separate them out again? Do you have nightmares of tiny tweezers, a magnifying glass,...

What makes up a solution? Are there variables to consider when mixing a solution? Find out with this overview.
