Exploring Concentrations in 5th Grade Science

Miss Patty at Casteel Innovation Lab explains concentrations of solutions using drink powder and water. She sets up an experiment to show how different amounts of solute and solvent affect concentration. Mrs. Lyon participates in a taste test to evaluate the solutions, highlighting the differences in sweetness and color. The video concludes with a summary of the experiment, emphasizing that concentration refers to the amount of solute dissolved in a solvent, and encourages viewers to try similar experiments at home.

What does a 'solution' refer to in chemistry?

• Only a liquid form

• A homogeneous mixture of solute and solvent

• A heterogeneous mixture

• A solid mixture

What role does the drink powder play in the solution?

• Catalyst

• Solvent

• Container

• Solute

If a solution appears darker, what does this indicate about its concentration?

• It is less concentrated

• It is more concentrated

• It has no solute

• It is more diluted

What was observed when the same amount of solute was used in different volumes of solvent?

• The concentration varied

• The taste was unchanged

• No solution was formed

• The color remained the same

Which cup did Mrs. Lyon find too sweet?

• Cup 2

• Cup 1

• Cup B

• Cup A

According to Mrs. Lyon, which cup tasted just like water?

• Cup A

• Cup B

• Cup 2

• Cup 1

What does it mean if a solution is 'dilute'?

• It has a high concentration of solute

• It has a low concentration of solute

• It is not mixed well

• It contains only solvent

What was the correct concentration according to the directions?

• Cup 2

• Cup B

• Cup 1

• Cup A

What should a solution not have to be considered a true solution?

• A solvent

• Any visible solids

• Water

• A solute

What experiment is suggested to be tried at home?

• Freezing mixtures

• Mixing different solvents

• Creating solutions with varying concentrations

• Boiling solutions
