The woman needs to make the box move faster. What can she do to make the box increase its speed in a forward direction?

• The woman can increase the mass of the box.

• The woman can apply a force on the box from the opposite direction.

• The woman can decrease the force on the box.

• The woman can apply a greater force on the box in the direction the box is moving.

A group of students was challenged to construct a boat that could transport 10 mL of corn syrup across a small, plastic swimming pool. Which QUESTION will best help the students design their boat?

• What force is needed to push the boat across the length of the pool?

• What boat shape is needed to lower the density of the boat and the corn syrup?

• What is the mass of the boat and the corn syrup?

• What is the distance from one point of the pool to the point on the exact opposite side?

Will is doing an experiment. He wants to find out how objects with different masses are affected when he pushes them with the same amount of force. To do his experiment, he has a cart and several weights he can put in the cart. By putting more weights in the cart, Will can make the cart more massive. By putting fewer weights, he can make the cart less massive. Will has a stopwatch, so he can measure how fast the cart goes. If he plans to study the relationship between the mass of the cart and its speed when pushed with the same amount of force, what else does Will need?

• a way to change the force pushing on the cart

• a way to change the kind of surface the cart travels on

• a way to push the cart with the same force every time

• a way to change the mass of the cart

A student predicts that water is denser than iron and cork. To test the prediction, the student pours 200 mL of water in a beaker and places a cork and an iron nail in the beaker. The image shows the student’s observations. Is the student’s prediction correct, and why?

• No. The iron nail sinks in water, indicating that iron is denser than water.

• No. The cork floats on water, indicating that cork is denser than water.

• Yes. The cork floats on water, indicating that water is denser than cork.

• Yes. The iron nail sinks in water, indicating that water is denser than iron.

A teacher prepares to dissolve 50 g of a solute. How does the surface area of the solute affect the rate at which the solute dissolves?

• The larger the total surface area of the solute, the faster the solute dissolves.

• The rougher the surface area of the solute, the faster the solute dissolves.

• The smaller the total surface area of the solute, the faster the solute dissolves.

• The smoother the surface area of the solute, the faster the solute dissolves.

A student makes two solutions (A and B). Solution A contains 200 mL of water and 20 g of sugar. Solution B contains 100 mL of water and 20 g of sugar.

Which solution is more concentrated, and why?

• Solution A; the amount of solvent is greater in solution A than in solution B.

• Solution A; the amount of solute is greater in solution A than in solution B.

• Solution B; the amount of solvent is less in solution B than in solution A.

• Solution B; the amount of solute is less in solution B than in solution A.

Which activity will result in a new substance when completed?

• softening butter

• chopping wood

• breaking a pencil in half

• roasting a marshmallow
