1. QuestionMultiple choice

What is the first step in solving an engineering problem?

Please select an answer first.

Correct answer: A

The correct answer is Define the problem and the criteria for success..

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: Engineers first identify the problem, goals, and constraints.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.

Engineers first identify the problem, goals, and constraints.

2. QuestionMultiple choice

A student tests three paper bridge designs with the same number of books. Why should the number of books stay the same?

Please select an answer first.

Correct answer: B

The correct answer is To make the test fair when comparing designs.

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: Keeping the load the same controls a variable during comparison.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.

Keeping the load the same controls a variable during comparison.

3. QuestionMultiple choice

A model car travels 2 meters in 4 seconds. What is its average speed?

Please select an answer first.

Correct answer: C

The correct answer is 0.5 meter per second.

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: Average speed is distance divided by time: 2 divided by 4 equals 0.5.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.

Average speed is distance divided by time: 2 divided by 4 equals 0.5.

4. QuestionMultiple choice

A student changes only the ramp height and measures how far a car travels. What is the independent variable?

Please select an answer first.

Correct answer: D

The correct answer is Ramp height.

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: The independent variable is the factor the student changes: ramp height.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.

The independent variable is the factor the student changes: ramp height.

5. QuestionMultiple choice

Which tool would best measure the temperature of water?

Please select an answer first.

Correct answer: A

The correct answer is Thermometer.

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: A thermometer measures temperature.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.

A thermometer measures temperature.

6. QuestionMultiple choice

A data table shows plant heights of 4, 7, 10, and 13 centimeters over four weeks. What pattern is shown?

Please select an answer first.

Correct answer: B

The correct answer is The plant grew 3 centimeters each week..

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: Each measurement increases by 3 centimeters.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.

Each measurement increases by 3 centimeters.

7. QuestionMultiple choice

Two materials are tested for keeping ice from melting. Material A leaves 80 grams of ice and Material B leaves 45 grams. Which material worked better?

Please select an answer first.

Correct answer: C

The correct answer is Material A.

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: More ice remaining means less melting, so Material A worked better.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.

More ice remaining means less melting, so Material A worked better.

8. QuestionMultiple choice

Why should an engineer test several versions of a design?

Please select an answer first.

Correct answer: D

The correct answer is Testing can reveal weaknesses and suggest improvements..

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: Repeated testing provides evidence for improving a design.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.

Repeated testing provides evidence for improving a design.

9. QuestionMultiple choice

A graph shows that a solar oven reaches a higher temperature when it faces the Sun. What conclusion is supported?

Please select an answer first.

Correct answer: A

The correct answer is The oven’s position affects the energy it receives..

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: The graph connects facing the Sun with a higher temperature.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.

The graph connects facing the Sun with a higher temperature.

10. QuestionMultiple choice

Which evidence would best support the claim that a filter removes particles from water?

Please select an answer first.

Correct answer: B

The correct answer is The filtered water has fewer visible particles than the unfiltered water..

  1. Read the investigation: Identify the system, evidence, pattern, or design problem described in the question.
  2. Use science evidence: Comparing visible particles directly tests the filter’s purpose.
  3. Check the claim: Choose the answer best supported by the Delaware Grade 5 DeSSA Science task.
