Students perform an investigation to determine which of four materials will keep a hot drink warm for the longest period of time.
The students gather four different cups, each made of a different material. The cups are the same size. The teacher pours equal amounts of heated water into the cups.
The students record the temperature of the water in each cup every minute for 4 minutes. The results are shown in the table.
Part A
Which material will keep a hot drink warm for the longest period of time?
Students learn that a construction company is planning to cut down trees on a hillside. The students design an investigation to determine how the removal of trees can affect runoff. Their procedure and design are shown.
Step 1. Get three containers of the same size and attach a cup to each container to catch the runoff.
Step 2. Fill each container with the same amount of soil.
Step 3. Grow plants in the soil of Container 1. Cover the soil with dead leaves in Container 2. Keep only soil in Container 3.
Step 4. Pour the same amount of water into each container.
Step 5. Measure the amount and the quality of water that runs off from the soil.
Which statement best describes an environmental effect of cutting down trees?
A student builds the circuit shown. The student closes Switch 1 and Switch 3.
Which lightbulb will glow?
Select ONE correct answer.
Students found a rock with fossils in a dry streambed. Which question can MOST LIKELY be answered by identifying the fossils in the rock?
A simplified food web is shown.
Which statement correctly describes part of the flow of energy in this food web?
The diagram shows where the sun appears to be throughout the day.
If the sun will be setting at 6:30 p.m., where will the sun MOST LIKELY appear at 3:00 p.m.?
Two types of gray wolves are shown.
The arctic wolf and the timber wolf have different physical characteristics, such as different fur color and thickness and different snout and ear size.
Which statement BEST explains why these two types of wolves have different characteristics even though they belong to the same species?

A partial food web is shown.
Which pair of animals compete directly for resources in the food web?
A group of students created a model to demonstrate some of the processes involved in the formation of sedimentary rock. The students used this procedure to create the model:
Put some sand into a rectangular tray and create a hill at one end with the sand.
Raise the end of the tray with the hill of sand by placing a block of wood under it.
Create a channel in the sand from the top of the sand hill to the bottom of the sand hill.
Pour water into the tray so that it flows through the channel.
Observe how the flowing water affects the sand.
The model is shown in the diagram.
Which TWO processes of sedimentary rock formation are being modeled AND how are they being modeled?
Read the procedure and look at the diagram carefully. Then enter your answer and explanation in the box provided.
Students research how long it takes different animal eggs to develop. The information the students collected is in the table shown.
Which statement is best supported by the data shown in the table?

Students create the circuit shown.
What do the lightbulb and the bell do when the switch is left open?
A student wants to investigate how the force with which a ball is thrown affects how high of a splash it makes in a pool.
Which table BEST represents how the investigation should be set up?
Which pair of activities are examples of bumblebees interacting with living parts in their environment?
