Florida SC.5.P.8.2
The Standard
Investigate and identify materials that will dissolve in water and those that will not and identify the conditions that will speed up or slow down the dissolving process.

What This Standard Means
What Students Need to Do
- Students test common solids in water and use observations to decide whether each forms a solution. They compare stirring, water temperature, and particle size to see how each changes dissolving time.
What Mastery Looks Like
- A student can correctly classify materials such as salt, sugar, and sand based on test results. They can plan a fair comparison by changing one condition and measuring dissolving time.
Common Misconceptions
- Students may think a dissolved solid has vanished or melted. They may assume stirring increases how much can dissolve rather than how fast it dissolves. Some think every solid will dissolve in hot water.
How to Assess It
- Give this exit ticket: “Sugar mixes evenly into warm water, while sand settles. Which material dissolved, and name two changes that would slow dissolving?”

Ways to Teach It
Test salt, sugar, sand, and pepper in clear cups of water, then record whether each remains visible or forms a solution.
Ask students to explain why a sugar cube and loose sugar dissolve at different rates in the same water.
Play a condition card game where students sort stirring, temperature, and particle size changes into faster or slower dissolving groups.
Compare stirring sugar into hot and cold drinks, then connect the results to making lemonade, tea, or cocoa.
