Floating and Sinking Test

Maeve made a clay boat that floats and will test her design. Why would she use a spring scale?

• To have a little extra clay.
• To make it a fair test.
• To make sure the boat floats.
• To try out the scale.

RJ is making a clay boat. Which design will hold the most marbles?

• Less space and higher sides.
• Less space and lower sides.
• More space and lower sides.
• More space and higher sides.

Objects displace the water they are in by

• absorbing some of the water.
• sitting on top of the water.
• pushing the water aside and sinking into it.
• letting the water rush in and fill it up.

Griff made a foil boat. Griff's boat is hard to push down in the water. Your inference is?

• It will hold more marbles than the others.
• It will hold fewer marbles than the others.
• It will sink when loaded with marbles.
• It will never sink when loaded with marbles.

In our lab on "shapes of clay," why did the sausage shaped clay sink?

• Because of its color.
• Because of its shape.
• Because of its size.

Make a prediction. Which clay shape will sink? Large bowl, small bowl, or ball?

• Large bowl
• Small bowl
• Ball

Why do some clay objects float?

• Their bottoms are flat.
• Their shapes are open.
• Their sizes are small.

Paulette calibrated her spring scale with paper clips. What unit of measure is she using?

• Clay balls
• Paper clips
• String marks
• Wire coils

What object is Paulette weighing?

• 1
• 2
• 3

Look at the graph. Compare the weight of the objects. What is the pattern?

• Out of water, the weights double from left to right.
• The weights show no pattern.
• When submerged, their weights are almost the same.
• When submerged, each one loses about the same amount of weight.
