Groups of students in a second-grade class are each given a square sheet of
aluminum foil and a basin of water. The groups are directed to manipulate the shape
of the sheet of aluminum foil so that it floats in the basin of water, and to then
manipulate the shape so that it sinks. Most of the groups begin making plans and
testing various shapes, but one group is struggling to come up with a plan.Which of
the following questions should the teacher ask to point the group toward a strategy to
complete the assignment?
A. How fast does aluminum foil absorb water?
B. Why are we using aluminum foil rather than paper for this activity?
C. Why are some boats made of wood while others are made of metal?
D. Which is heavier, a hollow or a solid object of the same size and material?
Give this one a try later!

,The students are looking at a profile of a local canyon wall. Sandy says, "I didn't
realize this area was once an ocean." The teacher asks the other students to explain
why they think Sandy may have come to this conclusion. Which student response
indicates a lack of understanding about the evidence and geologic history?
A. "I can see a layer of rock with all kinds of shells in it."
B. "The layers of rock are in different colors in the shape of an ocean wave."
C. "Two of the layers are sand, with a layer of shells between them."
D. "The fossils we can see are from species that lived in the ocean."

The kindergarten students are too short to use the wall-mounted water fountain in the
hallway next to their classroom. Their teacher would like the class to formulate a
solution to this problem. The teacher points out that answering questions can help
solve problems and directs the class to come up with questions about the
problem.Which two questions would most likely stimulate discussions that would lead
to the class generating possible solutions to this problem?
A. Can the water fountain be moved?
B. Why are we thirsty all the time?
C. Was this always the kindergarten classroom, or did our room use to have bigger
kids?
D. Is there enough space around the water fountain to place a step that people won't
trip over?
E. What's wrong with just taking a cup into the bathroom to get water from the sink?

, During a class demonstration, a teacher floats a small toy boat in the center of a long,
narrow rectangular tank filled with water. Initially, the water is still and the boat is not
moving. A student is instructed to predict what will happen if he uses his hand to
create a wave crest that travels toward the other end of the tank, as shown in the
figure. The student predicts the boat will be carried by the wave to the other end of
the tank.Which of the following statements indicates a misconception that the student
most likely has about water waves?A. Water waves get smaller as they get further
away.
B. Water waves transfer energy from one location to another.
C. Water particles at the surface move along the surface with the wave.
D. Water waves slow down when they encounter an obstacle.

C. Water particles at the surface move along the surface with the wave.
Students completed a simulation examining the erosion of soil by water and made
several conclusions.Which of the following student conclusions presents a
misconception?
A. "Erosion is always harmful to the environment."
B. "Erosion involves the movement of material from one place to another."
C. "The slope of the land affects erosion."
D. "The amount of vegetation affects erosion."

A. "Erosion is always harmful to the environment."
A teacher provides students with several rectangular samples of flexible materials,
with the same length and width but varying thickness. The students are asked what
causes the difference in stiffness among the materials. A student picks up a thin
aluminum foil and a basin of water. The groups are directed to manipulate the shape
of the sheet of aluminum foil so that it floats in the basin of water, and to then
manipulate the shape so that it sinks. Most of the groups begin making plans and
testing various shapes, but one group is struggling to come up with a plan.Which of
