1A student places a green plant in a sealed glass container filled with rich soil and waters it daily, but pumps out all the air. After a week, the plant wilts and stops growing. What does this demonstrate about plant growth requirements?

A.Plants need soil minerals more than air.

B.Plants require gases from the air in addition to water and light to grow.

C.Plants can grow normally without air if given extra water.

D.Plants only need air during nighttime hours.

Explanation: Plants take in carbon dioxide from the air through their leaves to build plant matter during photosynthesis. Without air, plants cannot synthesize food and will wilt.

2Where do plants acquire most of the raw materials they need to gain mass and build stem and leaf structures?

A.Mainly from minerals absorbed from garden soil

B.Mainly from carbon dioxide in air and water from soil

C.Mainly from solid fertilizer added to the roots

D.Mainly from heat particles radiating from the Sun

Explanation: Scientific evidence shows that plants gain almost all of their mass by taking in carbon dioxide from the air and water from the soil, combining them using light energy.

3A scientist grows lettuce plants in a hydroponic setup where roots sit in liquid water with dissolved nutrients, with zero soil present. The lettuce grows large and healthy. What claim does this evidence support?

A.Soil is not an essential requirement for plants as long as they receive air, water, nutrients, and light.

B.Plants do not need water if they are grown in light.

C.Hydroponic plants get all of their carbon mass from water molecules alone.

D.Soil is the main provider of mass for terrestrial plants.

Explanation: Hydroponic farming demonstrates that soil is not strictly required for plant mass; air (carbon dioxide) and water provide the primary building blocks.

4A student measures a pot containing 20 kilograms of dry soil and plants a 0.1-kilogram oak sapling. Five years later, the tree weighs 45 kilograms, but the dry soil mass decreased by less than 0.05 kilograms. How did the tree gain 44.9 kilograms of mass?

A.The tree converted sunlight energy directly into solid wood atoms.

B.The tree absorbed carbon dioxide from the air and water from the soil to synthesize plant tissue.

C.The soil regenerated its mass by converting root secretions back into dirt.

D.The tree absorbed heavy minerals from rain without using air.

Explanation: This classic experiment proves that plant mass does not come from soil. Plants build carbon-based molecules using air (CO2) and water (H2O).

5Which gas in the atmosphere is taken in by plant leaves and combined with water to make sugar molecules?

A.Oxygen

B.Carbon dioxide

C.Nitrogen

D.Helium

Explanation: Green plants take in carbon dioxide gas through microscopic pores called stomata on their leaves to make sugars.

6Two identical potted bean plants receive equal amounts of sunlight and air. Plant A receives 100 mL of water daily, while Plant B receives no water. After two weeks, Plant B wilts and stops growing. What essential role does water play in plant growth?

A.Water provides hydrogen and oxygen building blocks and maintains cell pressure for plant structure.

B.Water replaces the need for carbon dioxide gas in food production.

C.Water shields leaves from absorbing too much sunlight energy.

D.Water converts soil rocks into air particles.

Explanation: Water is both a chemical reactant for producing sugars and a fluid that maintains internal cell turgor pressure so plants stay upright.

7A plant is kept in a sealed chamber where the surrounding air contains tagged carbon atoms in carbon dioxide. After 48 hours of exposure to light, where will those tagged carbon atoms be located?

A.In the soil water below the roots

B.Inside newly formed plant sugars and stem tissue

C.Evaporated as pure liquid water droplets on the glass

D.Trapped inside nonliving rock minerals

Explanation: Plants incorporate carbon atoms from atmospheric carbon dioxide directly into their sugar molecules and structural tissues (cellulose).

8Why do garden plants wilt and droop when they experience a severe lack of water?

A.Water pressure inside plant cells decreases, causing the plant structure to lose stiffness.

B.The plant takes in too much carbon dioxide gas from the surrounding air.

C.Sunlight turns into shadow inside the plant stem.

D.Soil minerals push the leaves downward toward the ground.

Explanation: Water fills plant vacuoles and creates turgor pressure against cell walls. When water is scarce, cells lose pressure, causing wilting.

9A student compares clover plants growing in full sunlight with clover plants growing under a dense cardboard box. The boxed clover becomes pale yellow and stops expanding. What does this indicate about plant health?

A.Light energy is necessary for plants to produce chlorophyll and synthesize new plant matter.

B.Boxed plants absorb too much air from the dark container.

C.Sunlight drives root absorption of solid rocks.

D.Plants under boxes require double the normal amount of soil mass.

Explanation: Light energy powers the chemical conversion of carbon dioxide and water into food. Without light, green chlorophyll breaks down and growth halts.

10In a Narragansett Bay salt marsh food web consisting of marsh grass, grasshoppers, marsh periwinkle snails, and egret birds, which organism is the primary producer?

A.Grasshopper

B.Marsh grass

C.Marsh periwinkle snail

D.Egret bird

Explanation: Marsh grass is a photosynthetic plant that captures sunlight energy to make its own food, making it the producer in this ecosystem.

About the RI NGSA Science Grade 5 Exam

The Rhode Island Next Generation Science Assessment (NGSA) for Grade 5 measures student proficiency against the grades 3-5 band of the Next Generation Science Standards (NGSS). RIDE developed the assessment with Vermont and draws items from a shared multi-state bank. Results are reported as a scale score from 0 to 120 plus a separate domain performance level for each of the three science disciplines: Life Science, Physical Science, and Earth and Space Science. The test emphasizes three-dimensional learning, integrating Science and Engineering Practices (SEPs), Disciplinary Core Ideas (DCIs), and Crosscutting Concepts (CCCs) around real phenomena. This 100-question bank is an English-language four-option MCQ study adaptation for concept review, data analysis, and phenomena-based reasoning; it is not a simulation of the official cluster, graphing, or simulation item formats.

RI NGSA Science Grade 5 Study Tips from Top Performers

1Focus on claims, evidence, and scientific reasoning when evaluating phenomena questions.

2Understand that plants acquire materials for growth chiefly from air and water, not soil.

3Remember that total mass/matter is conserved during all physical state changes and chemical reactions.

4Understand how Earth's four spheres (geosphere, hydrosphere, atmosphere, biosphere) interact in natural phenomena.

5Practice reading charts, line graphs, and data tables to draw conclusions about shadows, constellations, and star brightness.

Frequently Asked Questions

Who takes the Rhode Island NGSA Grade 5 Science test?

All public school fifth graders in Rhode Island take the NGSA Grade 5 Science assessment annually during the spring testing window.

What learning standards are assessed on the RI NGSA Grade 5 Science test?

The assessment is aligned to the Next Generation Science Standards (NGSS). It measures the grades 3-5 grade band, covering Life Science, Physical Science, and Earth & Space Science.

What is the format of the official NGSA Grade 5 test?

The official test is computer-based through the RI NGSA Portal. Items are performance-task-like: a stimulus (passage, video, data set, or diagram) is followed by one or more linked questions. Item types include selected response, drop-down, fill-in-the-blank, graphing, and simulations, and a single item may have several parts.

How long is the Grade 5 NGSA Science assessment?

Students take two sixty-minute sessions, and they may use additional time if they need it.

How are scores reported for the RI NGSA?

Students receive a scale score between 0 and 120 that maps to one of four achievement levels: Beginning to Meet Expectations, Approaching Expectations, Meeting Expectations, or Exceeding Expectations. Individual student reports also give a domain performance level for each of the three science disciplines.

Is this OpenExamPrep practice bank an official test replacement?

No. This bank is an independent English-language four-option MCQ study adaptation. It reinforces grade 5 NGSS concepts, data skills, and vocabulary, but it does not reproduce the official phenomenon clusters, graphing items, or simulations, and it is not an official RIDE product.
