5th Grade – Science – Mixtures and Solutions Study Guide – Flashcards

Processes for Separating Mixtures: Use the picture Chart to answer the following Question: Process C uses magnetic attraction to separate a mixture. This would work if you are trying to separate which of the following items? a.Iron pellets from wood chips b.Sand and wood chips c.Salt from water d.Large iron pellets from small iron pellets

Processes for Separating Mixtures: Use the picture Chart to answer the following Question: Process D describes which of the following separation methods? a.Floatation b.Chromatography c.Evaporation d.Filtration

Processes for Separating Mixtures: Use the Chart Below to answer the following Question: Process A is known as "Filtration." This is the best method to use when: a.Separating sea shells from a tank of ocean water b.Removing salt that has dissolved in water c.Separating marbles into groups of different sizes/diameters d.Removing iron nails that have fallen into a box of aluminum screws

4. Which statement below is correct? a.Matter is made of very large particles. b.Matter has mass and takes up space. c.Matter is made of particles you can see d.Matter is always solid

6. In the diagram, "State of Matter A" is a solid. This means that it a.Equals the volume of its container b.Changes its shape c.Has a definite volume and shape d.Equals the shape of the container

7. Describe the difference in a solute and a solvent. The __________ is the part of a solution in the smaller amount and that is dissolved. The __________ is the part of the solution in the larger amount that dissolves the other substance.

8. Adding vinegar to baking soda produces a gas. When these substances are combined, they? a.Chemically combine to make a new substance that can be separated with chromatography. b.Make a solution that can be separated with filter paper. c.Chemically combine to make a new substance that cannot easily be separated. d.Make a mixture that can be separated with a screen.

9. The particles in the diagram of mixtures will dissolve at different rates. What can be done to increase the rate of dissolving? a.Freeze the mixture b.Keep the mixture away from light c.Stir the mixture d.Keep the mixture away from air

10. Explain the difference between a heterogeneous and a homogeneous solution? ____________mixtures/solutions have different parts you can plainly see and can easily be separated. Ex. Trail Mix. A ____________ mixture/solution looks the same throughout and cannot be easily separated. Ex. Sweet Tea

11. The beakers in the diagram show the same solution with varying (different) concentrations. The easiest way to get Solution A to look the same as Solution D is to: a.Change the solute b.Add more solute c.Stir the solution d.Add more water

12. A characteristic of all mixtures is that: a.The particles of the substances are hard to separate b.The parts of a substance spread evenly through another substance c.The particles of the substances are joined chemically d.The substances can be put together in any amounts

13. How do the particles in the solution in Container B differ from other mixtures like the one in Container A? a.They can be a mixture but not a solution b.They have the same properties as they did before being mixed c.They can be separated easily d.They cannot be seen because they are very small and spread evenly throughout the mixture.

A mixture/solution that looks the same throughout and cannot be easily separated, is called? Ex. Sweet Tea

A mixture/solution that have different parts you can plainly see and can easily be separated is called? Ex. Trail Mix.
