This quiz helps your child practice kindergarten science questions and learn about plants, animals, and weather. Play a short set, see answers right away, and use the results to guide what to review next. For more practice, explore science questions for kids or build skills step by step with simple science questions.

What do plants use to make their food?
Rocks
Water
Soil
Sunlight
Plants use sunlight in a process called photosynthesis to convert water and carbon dioxide into glucose and oxygen. This process happens in the chlorophyll inside leaves. Without sunlight, plants cannot produce the energy they need to grow.
Which animal is a mammal?
Parrot
Cat
Lizard
Frog
Mammals are warm-blooded animals that have fur or hair and usually feed their babies with milk. Cats have fur and produce milk for their kittens, so they are mammals. Lizards, frogs, and parrots do not feed their young with milk and are classified as reptiles, amphibians, and birds, respectively.
Which of these is one of your five senses?
Hearing
Running
Thinking
Jumping
The five senses are sight, hearing, smell, taste, and touch. Hearing allows us to detect sounds with our ears. Running, thinking, and jumping are actions or processes, not senses. Each sense helps us learn about the world around us.
What color is the sky on a clear day?
Blue
Red
Yellow
Green
On a clear day, the sky appears blue because molecules in the air scatter blue light from the sun more than other colors. This scattering effect, called Rayleigh scattering, makes the sky look blue to our eyes. Green, yellow, and red are not scattered as much, so they are less visible.
Which of these is a fruit?
Bread
Lettuce
Carrot
Apple
A fruit is the part of a plant that contains seeds. Apples grow from flowers and have seeds inside, so they are fruits. Carrots and lettuce are vegetables that grow from roots and leaves, and bread is made from grains processed by humans.
Which of these animals lives in the ocean?
Monkey
Elephant
Dolphin
Tiger
Dolphins are marine mammals that live in oceans and seas around the world. They are adapted to swimming with streamlined bodies and fins. Elephants, tigers, and monkeys live on land, not in the ocean.
What form does water take when it gets very cold?
Rain
Fog
Steam
Ice
When water freezes, it changes from liquid to solid, forming ice. This happens at or below 0°C (32°F). Steam is water vapor, rain is liquid falling from clouds, and fog is tiny water droplets suspended in air.
What do you call baby bees?
Puppies
Chicks
Larvae
Cubs
Bee babies are first hatched from eggs into a stage called larvae. Larvae are worm-like and are fed by worker bees until they become pupae. Cubs are baby bears, puppies are baby dogs, and chicks are baby birds.
Which season comes after winter?
Summer
Autumn
Spring
Winter
Seasons follow a cycle: spring, summer, autumn (fall), and winter. After winter ends, temperatures warm and plants begin to grow again in spring. Summer is the warmest season, and autumn follows summer.
Why do leaves often change color in the fall?
More sunlight
Leaves get more water
Bees come home
Trees prepare for winter
As days get shorter and temperatures drop in autumn, plants stop making chlorophyll, the green pigment. Without new chlorophyll, other pigments like reds, oranges, and yellows become visible in leaves. This change helps trees conserve energy and prepare for winter.
What kind of rock is formed when lava cools?
Metamorphic
Sedimentary
Igneous
Mineral
Igneous rocks form when molten rock (lava or magma) cools and solidifies. Lava cools on the Earth's surface to make extrusive igneous rocks like basalt. Sedimentary rocks are made from layers of sediment, and metamorphic rocks come from existing rocks under heat and pressure.
Photosynthesis is the process by which plants make food. Which color of light do they use best?
Green
Yellow
Purple
Red
Chlorophyll in plant leaves absorbs red and blue light most efficiently for photosynthesis. Red light provides energy for making sugars during this process. Green light is mostly reflected, which is why plants look green.
Which planet is known as the Red Planet?
Mars
Venus
Earth
Jupiter
Mars is often called the Red Planet because of its reddish appearance caused by iron oxide (rust) on its surface. The iron-rich dust gives the planet a distinctive red color when viewed from space. Venus, Earth, and Jupiter do not have this rusty surface and appear different in color.
Which of these explains why sound travels faster in water than in air?
Air blocks sound
Water is heavier
Water molecules are closer together so vibrations travel faster
Water is colder than air
Sound travels by vibrating particles in a medium. In water, molecules are packed much more closely than in air, allowing vibrations to pass more quickly from one molecule to another. Air has more space between molecules, so sound waves move slower.
What do we call the change of a caterpillar into a butterfly?
Photosynthesis
Germination
Metamorphosis
Erosion
The transformation of a caterpillar into a butterfly is called metamorphosis. During metamorphosis, the caterpillar forms a chrysalis and its body reorganizes into an adult butterfly. Photosynthesis is how plants make food, germination is seed sprouting, and erosion is the wearing away of rocks.

Study Outcomes

  1. Identify Basic Science Concepts -

    After completing the quiz questions for kindergarten, children will be able to recognize fundamental science ideas such as plants, animals, and simple weather phenomena.

  2. Recognize Living vs. Nonliving Things -

    Kids will learn to distinguish between living creatures and nonliving objects by answering science questions for kindergarten.

  3. Describe Natural Phenomena -

    Through easy science questions for kids, learners will describe everyday phenomena like day and night or why objects float and sink.

  4. Apply Observational Skills -

    Engaging science questions for kindergarten help children practice careful observation and draw conclusions from visual cues.

  5. Expand Science Vocabulary -

    By encountering key terms in the quiz, kids will build a stronger science vocabulary to discuss basic concepts confidently.

  6. Build Confidence in Learning -

    Successfully answering quiz questions for kindergarten encourages self-assurance and a positive attitude toward exploring science.

Cheat Sheet

  1. The Five Senses -

    Children learn to identify sight, hearing, smell, taste, and touch by exploring everyday objects like bells (hear) or flowers (smell). A fun mnemonic - "Silly Hippos Smell Tasty Toaster" - helps recall the order sight, hearing, smell, taste, touch. Engaging in sensory stations boosts observational skills and vocabulary (National Science Teaching Association).

  2. Plant Life Cycle -

    Kindergartners discover how a seed becomes a sprout, seedling, and flowering plant by planting beans in a clear cup to watch roots grow. Emphasize the stages "seed → sprout → plant → flower" with picture cards from university outreach programs (e.g., USDA). This hands-on cycle model reinforces growth concepts and responsibility in caring for living things.

  3. States of Matter -

    Introduce solids, liquids, and gases using ice cubes, water, and steam from a kettle to show how matter changes with temperature (NASA Science). A simple rhyme - "Solid stays put, liquid flows, gas goes!" - helps kids remember the three states. Demonstrating melting and freezing sparks curiosity about everyday chemistry.

  4. Animal Groups -

    Teach basic classification by sorting toy animals into mammals, birds, fish, reptiles, amphibians, and insects based on characteristics like fur, feathers, scales, and number of legs (Smithsonian's National Zoo). For example, a dog (mammal) has fur and feeds babies milk, while a frog (amphibian) lives in water and on land. Sorting games build critical thinking and early taxonomy skills.

  5. The Water Cycle -

    Explain evaporation, condensation, and precipitation through a mini "rain in a jar" experiment: warm water evaporates, condenses on a cool lid, then drips like rain (NOAA education resources). Use the kid-friendly acronym "ECP - Every Cloud Pops!" to recall each step. This visual model links weather patterns to daily life and builds foundational Earth science knowledge.
