The Socha family cooks breakfast together. Jonathan observes how the food changes as it cooks. Which of the following changes is caused by temperature?

• A stick of butter is sliced into pieces.

• Flour and water are mixed to make pancake batter.

• Pancake batter is poured onto a griddle.

• Pancake batter is changed into a cooked pancake.

At a laundromat, Kyra observes that the electric dryer makes clothes both drier and hotter. Which energy transformation in the dryer best explains this observation?

• electrical energy to sound energy

• mechanical energy to electrical energy

• electrical energy to thermal energy

• thermal energy to mechanical energy

A science class is studying the changes that occur to wood when it is burned in a fireplace. How is burning wood different from sawing, splitting, or sanding the wood?

• Burning changes wood into new materials that have different properties from wood.

• Burning changes wood into new materials that have the same properties as wood.

• Burning increases the temperature of wood, but none of its other properties.

• ^{Burning changes the size of wood pieces, but none of its other properties.}

Kaden and Ruben are investigating the forces and motion that affect playground balls. They kick several playground balls and observe their motion across flat grass. If all the kicks are equally strong, which playground ball will most likely travel the fastest after it is kicked?

• the ball that has the largest width

• the ball that has the coldest temperature

• the heaviest ball, which has the most mass

• the lightest ball, which has the least mass

Amelia and Josie are investigating the electrical circuit shown here.

Which is the most likely reason that the light bulb is not lit?

• The switch is closed, so current cannot flow through the switch.

• The wires do not form a closed circuit, or complete loop.

• The wires allow current to flow through the battery, but not the light bulb

• The wires allow current to flow through the light bulb, but not the battery.

LaToya and Ari are studying an electrical circuit. They wonder why the cores of the wires are often made of copper or other metals, not materials such as plastic or glass.

Which statement explains why copper is more useful in wires than plastic or glass?

• Copper is the better insulator of electricity.

• Copper can be drawn into thinner wires.

• Copper is the better conductor of electricity.

• Copper can be drawn into thicker wires.

In a science experiment, Timor rolls a wooden ball across three flat surfaces. In each trial, the ball begins rolling with the same speed. The table shows the results.

Which statement best explains why the ball rolled farthest on concrete?

• Concrete provided the greatest friction on the ball.

• Concrete provided the least friction on the ball.

• Timor applied a greater force on the ball when he rolled it on concrete.

• The ball was pulled the strongest by gravity when it was rolled on concrete.
