1Maya sets up an experiment to test bean plant growth under three different light conditions: full sun, partial shade, and deep shade. She uses identical pots, soil, and water for all plants. What is the independent variable in Maya's experiment?
A.The height of the bean plants
B.The amount of sunlight received
C.The type of soil in the pots
D.The amount of water given each day
Explanation: The independent variable is the factor intentionally changed by the experimenter. Maya changes the light condition (full sun, partial shade, deep shade) to test its effect on plant growth.
2Liam needs to measure exactly 35 milliliters (mL) of liquid fertilizer for a classroom garden project. Which measurement tool should he use for the most accurate result?
A.A 30-centimeter ruler
B.A graduated cylinder
C.A spring scale
D.A digital balance
Explanation: A graduated cylinder is designed specifically to measure liquid volume in milliliters accurately. Rulers measure length, spring scales measure force, and digital balances measure mass.
3A student engineering team notices that rain barrel water overflows into the school garden during heavy downpours, washing away topsoil. What should be the team's first step in the engineering design process?
A.Build a working model using plastic pipes immediately
B.Define the specific problem and identify constraints
C.Test three different drainage solutions in the garden
D.Choose the cheapest material before measuring the barrel
Explanation: The engineering design process begins by defining the problem clearly and identifying constraints such as budget, space, and available materials before brainstorming or building prototypes.
4Which of the following statements is a testable scientific claim rather than an opinion?
A.Sunflowers are the prettiest flowers growing in Minnesota gardens
B.Plants grown in compost-enriched soil grow taller than plants grown in sand
C.Gardening is the most enjoyable outdoor activity for elementary students
D.Red tomatoes taste much better than yellow tomatoes
Explanation: A testable scientific claim can be evaluated through controlled measurement and observation (measuring plant height in compost vs. sand). Opinions reflect personal preferences.
5A student times how long it takes a toy car to roll down a 1-meter ramp. Why is it important to repeat the investigation three times and calculate an average?
A.To change the independent variable after each attempt
B.To reduce the effect of accidental timing errors and increase reliability
C.To ensure the car moves faster during the final trial
D.To make the science lab take more time to complete
Explanation: Repeating trials reduces the impact of random measurement errors and demonstrates that results are consistent and reliable across multiple tests.
6Students want to test how ramp surface roughness affects the distance a toy car travels. Which variable must be kept constant (controlled) throughout the test?
A.The roughness of the ramp surface
B.The height of the ramp
C.The distance the car travels across the floor
D.The time of day the test is conducted
Explanation: To ensure a fair test when investigating surface roughness (independent variable), the ramp height, car mass, and release point must be controlled so only roughness affects distance.
7A class recorded radish seed germination in three dishes kept at different temperatures for 5 days: - Dish A (10°C): 2 seeds sprouted - Dish B (20°C): 9 seeds sprouted - Dish C (30°C): 5 seeds sprouted Which conclusion is best supported by these data?
A.Radish seeds only sprout at temperatures above 30°C
B.Radish seeds sprout best near 20°C compared to 10°C or 30°C
C.Temperature has no effect on radish seed sprouting
D.Dish A received more sunlight than Dish B
Explanation: Dish B at 20°C had 9 seeds sprout, which is higher than Dish A (2 seeds) and Dish C (5 seeds), indicating that 20°C was the most favorable temperature tested.
8An engineering challenge requires students to build a bridge across a 30-centimeter gap using only 5 sheets of index paper and 10 centimeters of tape. In engineering, the limit of using only 5 paper sheets is called a:
A.Hypothesis
B.Constraint
C.Criterion
D.Variable outcome
Explanation: A constraint is a limitation or restriction placed on an engineering design, such as limits on materials, budget, time, or size.
9A student wants to test which insulating material keeps warm water hot the longest. Which hypothesis is written correctly for a scientific investigation?
A.I think foam cups are much nicer than paper cups
B.If warm water is placed in a foam cup, then it will stay warm longer than in a paper cup because foam traps air pockets that slow heat transfer
C.Warm water should always be served in insulated mugs during winter
D.Paper cups are easier to recycle than foam cups after use
Explanation: A well-written scientific hypothesis clearly connects the independent variable (cup material) to the expected outcome (temperature retention over time) with a testable scientific reason.
10Students measured soil loss from two model hillsides after spraying equal amounts of water: - Hillside 1 (Bare Soil): 120 grams of soil washed away - Hillside 2 (Grass Cover): 15 grams of soil washed away What evidence-based conclusion can be drawn from this investigation?
A.Bare soil absorbs more water than grass-covered soil
B.Plant roots help hold soil in place and significantly reduce water erosion
C.Hillside 2 experienced heavier rainfall than Hillside 1
D.Grass plants prevent water from evaporating into the air
Explanation: Comparing 15 g of soil loss on the grass hillside to 120 g on the bare hillside provides direct evidence that plant cover and roots anchor soil, reducing erosion.

About the MCA Science Grade 5 Exam

The Minnesota Comprehensive Assessment (MCA-IV) Science Grade 5 is Minnesota's state-mandated summative assessment administered each spring to measure 5th-grade student mastery of the 2019 Minnesota Academic Standards in Science (first administered in 2025). Administered online through Pearson TestNav, the fixed-form test presents phenomenon-based scenario clusters that ground questions in real-world scientific investigations and engineering problems, reporting three equally weighted content areas: Practices in Earth Science, Practices in Life Science, and Practices in Physical Science. OpenExamPrep offers a 100-question practice bank formatted as 4-option multiple-choice questions with detailed explanations; it is an English-language MCQ study adaptation, not an official-format simulation (the official test also uses technology-enhanced and multi-part items).

Assessment

Fixed-form online test reporting three equally weighted content areas: Practices in Earth Science, Practices in Life Science, and Practices in Physical Science (13-15 questions / 15 points each). Items integrate science and engineering practices with disciplinary core ideas from the 2019 Minnesota Academic Standards in Science.

Time Limit

Untimed; MDE estimated testing time is 1.75 to 2 hours, typically across 1 or 2 sessions.

Passing Score

Reported in four performance levels on a 501-599 scale: Beginning (501-539), Intermediate (540-549), Meets (550-560), and Advanced (561-599). Scale score of 550 or higher demonstrates proficiency (MDE cut scores, September 2025).

Exam Fee

$0 (state-funded) (Minnesota Department of Education (MDE))
