You and your friends are at the park on a sunny day. You are playing on the slide. As you slide down, the hot metal slide burns your legs.
Why did this happen and why you didn't burn your hands when you climbed up the rope ladder?
Metal is a good conductor of heat, the rope is not.

Students read a description of pennies and claim that a new substance is formed when the pennies get dull. Select the sentence from the excerpt below that best supports their claim.
A Pennies before 1982 were made from a metal called copper. B These pennies were bright and shiny when they were first made. C However, over time these pennies would become dull and look dirty. D This happened because the copper on the penny reacted with the oxygen in the air around it and became copper oxide.
D This happened because the copper on the penny reacted with the oxygen in the air around it and became copper oxide.

A dull penny actually weighs just a tiny bit more than a shiny penny. This is because copper oxide is heavier than copper. What evidence could be collected to check that this claim is true?
A Use a triple beam balance (a scale) to weigh a dull penny and a shiny penny then compare.
B Count how many dull pennies versus shiny pennies there are in the picture.
C Hold a dull penny in one hand and shiny penny in the other then try to feel the difference.
D Weigh all nine pennies together and then divide by 9 to get the average weight.
A Use a triple beam balance (a scale) to weigh a dull penny and a shiny penny then compare.

Why must a dull penny weigh a tiny bit more than a shiny penny?
A Shiny substances are lighter than dull substances.
B More oxygen is added to the surface of the penny over time.
C Older objects always weigh more and the dull pennies are older.
D Oxygen and copper are two substances but copper oxide is only one.
B More oxygen is added to the surface of the penny over time.
