This 5th grade check covers mixtures and solutions in three parts. Students write M or S for six examples such as soil, sugar in tea and air, match three mixtures to a separation method, and answer five multiple-choice questions on dissolving. Pages 1 and 2 are the check and page 3 is the key. It supports NGSS 5-PS1-3 and 5-PS1-4.
5-PS1-3
“Make observations and measurements to identify materials based on their properties.”
The matching task in Part 2 picks a separation method from a property of the mixture.
5-PS1-4
“Conduct an investigation to determine whether the mixing of two or more substances results in new substances.”
Part 1 and questions 1, 2 and 5 check what students know about dissolving.
Six boxes with a short answer line: soil, salt water, fruit salad, sugar in tea, coins in a jar and air. Students write M for a regular mixture or S for a solution.
Three mixtures to match to a lettered method: sand and water, salt water, and iron and sand. The methods are evaporate the water, use a magnet and pour through a filter.
Five questions with three tick-box options each: what salt does in warm water, which part is the solute in sugar water, what is true of all mixtures, what makes a solid dissolve faster, and why a solution is a special kind of mixture.
M or S for each example, the method letter for each mixture, and the correct option ticked for all five questions.
End of unit check
Use it as a short end-of-unit check. Part 1 quickly shows who still files air and sugar in tea under regular mixtures.
Self-mark
Hand out the key afterwards for self-marking. Students correct in a different color and note which items surprised them.
Pick a reteach group
Look at questions 2 and 5 first. Anyone who misses solute or why a solution is special needs those words again before the next topic.
