A geode is not a living thing. A geode does not have all the traits of a living thing. It contains minerals that formed slowly over many years. But it does not need food or water. Aloe vera is a living thing. Aloe vera grows and responds to its environment. It needs food and water. It is made up of many cells. Aloe vera is a plant. It uses water, air, and sunlight to make food. A brick wall is not a living thing. Brick walls do not have all of the traits of living things. They do not grow or respond to their environment. They do not need food or water. Rain is not a living thing. Rain is made of water. It helps living things survive. But it does not have all the traits of a living thing.

Select the bird.

[ "brown pelican", "spotted dolphin", "zebra", "great white shark" ]

A

A brown pelican is a bird. It has feathers, two wings, and a beak. Brown pelicans live near water. They can dive underwater to catch fish. A spotted dolphin is a mammal. It has hair and feeds its young milk. Dolphins may look like sharks or other fish, but they are mammals! When a baby dolphin is born, it has hair around its jaw. This hair falls out as the dolphin grows. A great white shark is a fish. It lives underwater. It has fins, not limbs. Great white sharks can live for up to 70 years. A zebra is a mammal. It has hair and feeds its young milk. Zebras eat mostly grass. But they sometimes eat other types of plants, such as shrubs or tree bark.

What do these two changes have in common? dry ice sublimating and becoming a gas grilling a hamburger

[ "Both are chemical changes.", "Both are caused by heating.", "Both are only physical changes.", "Both are caused by cooling." ]

B

Step 1: Think about each change. Dry ice is solid carbon dioxide. When dry ice gets warm, it changes state and becomes carbon dioxide gas. This change of state, from solid to gas, is called sublimation. Dry ice becoming a gas is a physical change. A change of state does not form a different type of matter. Grilling a hamburger is a chemical change. Heat from the grill causes the matter in the meat to change. Cooked meat and raw meat are different types of matter. Step 2: Look at each answer choice. Both are only physical changes. Dry ice sublimating is a physical change. But grilling a hamburger is not. Both are chemical changes. Grilling a hamburger is a chemical change. But dry ice sublimating is not. Both are caused by heating. Both changes are caused by heating. Both are caused by cooling. Neither change is caused by cooling.
