Mississippi Science P.5.5B.2
The Standard
- P.5.5B
- Students will demonstrate an understanding of mixtures and solutions.
Analyze and interpret data to communicate that the concentration of a solution is determined by the relative amount of solute versus solvent in various mixtures.

What This Standard Means
What Students Need to Do
- Students read amounts of dissolved material and water in different mixtures. They compare those amounts to decide which solution is more concentrated and explain their choice using the data.
What Mastery Looks Like
- A student can tell that 2 g of salt in 100 mL of water is more concentrated than 4 g in 400 mL. They can also spot when two mixtures have the same concentration, even if one is larger.
Common Misconceptions
- Students may pick the mixture with more salt without checking how much water it has. Some think adding water adds more salt or makes the solution more concentrated.
How to Assess It
- On an exit ticket, show A: 2 g salt in 100 mL water and B: 4 g salt in 400 mL water. Ask which is more concentrated and why.

Ways to Teach It
Mix 1 teaspoon and 3 teaspoons of powdered drink mix into separate cups of 100 mL water, then record the amounts and compare color.
Ask, "Which is more concentrated: 2 g salt in 100 mL water or 3 g salt in 300 mL water, and why?"
Have pairs sort recipe cards by concentration: 1 teaspoon of mix in 100 mL water, 2 in 200 mL, and 3 in 100 mL.
Show powdered lemonade directions and ask how adding 100 mL water to one prepared cup changes its concentration.
