Building Miniature Stream Tables Quiz

What is one of the main advantages of using miniature stream tables in a classroom setting?

• They are more durable than large stream tables.

• They require no preparation.

• They are less expensive and save space.

• They are more effective than large stream tables.

Why should you avoid using metal or flimsy plastic paint roller pans for stream tables?

• They are too expensive.

• They do not stand up at an angle.

• They are too heavy to move.

• They are not available in stores.

What is the purpose of drilling holes in the paint roller pans?

• To attach the pans to a stand.

• To allow water to drain.

• To improve their appearance.

• To make them lighter.

Why is it important to wet the sand before starting the stream table experiment?

• To prevent the sand from blowing away.

• To ensure the sand stays in place.

• To see channel formation clearly.

• To make the sand easier to handle.

What should students do to help the stream form in the sand?

• Pour water directly onto dry sand.

• Use a stick to dig a deep trench.

• Create a small channel with their hand.

• Add more sand to the table.

How should students control the flow of water when forming streams?

• Use a cup with a hole in the bottom.

• Use a hose to direct the water.

• Pour water quickly from a bucket.

• Sprinkle water with their hands.

What observations should students make during the first trial of the stream table experiment?

• The speed of the water flow.

• The color of the sand.

• The formation and characteristics of channels.

• The temperature of the water.

What variable can be changed to test its effect on stream formation?

• The color of the water.

• The angle at which the water is poured.

• The size of the paint roller pan.

• The type of sand used.

How can ice cubes be used in the stream table experiment?

• To change the color of the water.

• To simulate glacial erosion.

• To cool down the sand.

• To add weight to the sand.

What should students do between trials to ensure accurate results?

• Use a different type of water.

• Change the paint roller pan.

• Add more sand to the table.

• Smooth out the sand and start fresh.
