After lunch, a student made a model to show where the energy in her jam sandwich came from. Arrows show the flow of energy, where the energy came from, and where it went. Can you help complete the model?

• ground --> strawberry plant ---> farmer --> supermarket

• sun --> strawberry plant --> jam sandwich --> farmer

• jam sandwich --> strawberry plant --> farmer --> student

• sun --> strawberry plant --> jam sandwich --> student

In a classroom experiment, 100 grams of water were placed in a beaker and left uncovered. Three days later, the teacher weighed the beaker again, and the class observed that there were only 94 grams of water. What is the most reasonable conclusion for this experiment?

• The scale is not working because the water should weigh the same.

• Some water was spilled.

• There were 4 grams of water that evaporated as gas.

• There were 6 grams of water that evaporated as gas.

Imagine you found a small insect to keep in a cage. You are not sure what it is or what it eats, so you give it a variety of grass, leaves, and seeds from outside. If the insect gets bigger over the next week, what conclusion makes the most sense?

• The food did not have enough nutrients for growth.

• The food can be found in the insect's natural habitat.

• The food had enough nutrients for the insect to grow.

• The food was bad for the insect.

A group of students have repeated the experiment measuring the mass of soil and a plant over time. The plant got heavier, and the soil stayed the same weight. One student argued that the increased mass of the plan was only from the water they gave it, and not from the air. Is the student correct or not, and why?

• The student is correct because water has mass, but air does not.

• The student is correct because air is basically nothing.

• The student is incorrect because aur provides energy to the plant.

• The student is incorrect because air does have matter and mass.

A student watches her uncle heat chocolate in a pot so they can dip in bananas and cake for dessert. The uncle is using a candy thermometer that shows degrees Fahrenheit. The student makes the following observations.

At 75 degrees, the chocolate is shaped into small, solid, "chip" shapes.

At 86 degrees, the chocolate chips are losing their hard edges.

At 90 degrees, they can stir the chocolate with a spoon.

What happened to the chocolate chips?

• The chocolate chips became a solution.

• The chocolate chips changed in some physical properties.

• The chocolate chips became a mixture.

• The chocolate chips weighed less after 90 degrees.

Alexis measures the mass of a nail as 2.3 grams. She places the nail in a bottle of water and lets it sit for a year. After a year, the nail and the water are red and rusty. She removes the nail and measures its mass. The mass is not 2.1 grams. Alexis concludes that the total mass of her experiment decreased. Identify her mistake.

• Both measurements round up to 2 grams, so they are the same.

• Alexis did not collect and measure the rust in the water, so her measurement is incomplete.

• Alexis probably made an error when she measured the mass of the nail.

• There is no mistake.
