Science Prep 5th grade part 2

When a whale comes to the surface, it exhales warm air through its spout. Scientist want to collect samples from whale spouts to learn more about the health of whales.

Scientists are considering two methods for collecting samples:

Drone: A silent remote-controlled drone robot that flies over a whale and collects samples quickly. The cost is $5,000.

Boat: A gasoline-powered speed boat that is already owned by the scientist. It drives up to a whale and a passenger collects a sample quickly. The cost is $10.

Multiple Select

Below are some choices. Select the requirement(s) that best fit the drone (Can be more than one).

• Quiet

• low cost

• least harmful to the environment

• low cost

• least harmful to the environment

Multiple Choice

A student competes in the long jump track event. She runs forward, jumps up into the air as she runs, reaches her highest point, and returns to the ground. A student claims that gravity acts on the long jumper throughout her jump. Which statement BEST supports this claim?

• Objects weigh less on the moon than on Earth.

• Objects thrown up in the air return back to Earth.

• Heavy objects fall at the same speed as light ones.

• The force of gravity decreases as the distance between objects increases.

Multiple Choice

Which picture shows the correct direction of the force of gravity on the long jumper as she moves through the air?

Multiple Choice

Glaciers are large sheets of ice found in areas where the air temperature remains cold most of the year. Students use a computer model to study how glaciers can affect land and living things. The students also study data that show that glaciers are melting rapidly. Which changes to the computer model should the students make to show the most likely effect of melting glaciers?

• Make the oceans more salty

• Cover some costal lands with water.

• Decrease the amount of water in the atmosphere.

• Move animals living at the poles closer to the equator.

Multiple Choice

5) This is a picture of an electric circuit containing a wire, a battery, a switch, and a lightbulb. A student wants to use the circuit to find the battery that lasts the longest. Which test should the student perform? Complete the sentence by selecting the correct word from the menu. The student should change the type of __________ and measure how long the circuit works.

• switch

• wire

• battery

• lightbulb

Multiple Choice

The pie charts show where the water on Earth is. Most of the water is in the oceans. Most of the water that is not in the oceans is frozen in ice caps and glaciers.

Look at the pie charts. Choose the statement that is true.

• Most of Earth's freshwater is on the surface.

• Most of Earth's freshwater is under ground.

• Most of Earth's freshwater is frozen.

• Most of Earth's freshwater is in swamps.

Multiple Choice

Look at the pie charts. Choose the statement that is true.

• Most of Earth's surface freshwater is found in rivers.

• Most of Earth's surface freshwater is found in swamps.

• Most of Earth's surface freshwater is in lakes.

• Most of Earth's surface freshwater is in oceans.

A group of students enters an engineering competition. They have to build a small boat using only a single piece of aluminum foil. The boat that holds the greatest number of pennies without sinking wins the competition. The students are given these materials: Pennies, Square piece of aluminum foil (15x15 cm), Large plastic container, half filled with water. The first thing they need to do is create a design. Select THREE factors the students need to consider when creating a design for the foil boat.

• shape of the boat

• number of pennies

• what type of material to use

• how much aluminum foil costs

• what makes a boat float or sink

Students are learning about butterfly habitats and want to design a garden at their school to attract butterflies. What do the students need to know now? (Might be more than one answer.)

• Amount of money in the budget

• Types of plants that attract butterflies in the region

• How to expand the layout of the butterfly garden

• Types of plants that attract butterflies in the region

• How to expand the layout of the butterfly garden

Multiple Choice

Two students are looking at stars in the sky on a moonless night. One student points at a certain star and says that it is closer to Earth than all the other stars. What evidence BEST supports the student's claim about the closeness of the star?

• The star is a different color than the other stars.

• The star is twinkling more than the other stars.

• The star appears brighter than the other stars.

• The star appears smaller than the other stars.
