Which state of matter is water at room temperature?
Solid
Gas
Liquid
Plasma
At room temperature (around 20°C), water molecules move enough to flow but remain close together, giving it a liquid state. This allows water to take the shape of its container while keeping a definite volume.
Which force pulls objects toward the Earth?
Magnetism
Gravity
Electricity
Friction
Gravity is the attractive force that pulls objects toward the center of the Earth. Concepts like magnetism and electricity involve different interactions and do not cause all objects to fall downward.
Which of the following is a living thing?
Dog
Car
Rock
Chair
A dog is a living organism because it grows, reproduces, responds to stimuli, and is made up of cells. Rocks, chairs, and cars do not carry out these life processes.
What is the process called when a solid turns directly into a gas without becoming a liquid first?
Freezing
Condensation
Evaporation
Sublimation
Sublimation is the phase change from solid directly to gas, skipping the liquid phase. A common example of this is dry ice (solid carbon dioxide) turning into carbon dioxide gas.
In the life cycle of a butterfly, which stage comes immediately after the caterpillar (larva) stage?
Egg
Nymph
Adult
Pupa
After the larva (caterpillar) stage, the insect enters the pupa stage (chrysalis), during which metamorphosis occurs. It then emerges as an adult butterfly.
What process in the water cycle describes water vapor cooling and changing into liquid droplets?
Evaporation
Collection
Precipitation
Condensation
Condensation is when water vapor in the air cools enough to form liquid water droplets, often leading to cloud formation. It is the reverse of evaporation.
If you push an object with twice the force while keeping its mass the same, what happens to its acceleration?
Halves
Stays the same
Doubles
Becomes zero
According to Newton's second law (F = m·a), acceleration is directly proportional to force when mass is constant. Doubling the force doubles the acceleration.
In a vacuum where there is no air resistance, if you drop a heavy rock and a light feather at the same time, what happens?
Cannot tell without more data
The feather lands first
Both land at the same time
The rock lands first
Without air resistance, gravity accelerates all objects equally regardless of mass. Both the rock and the feather fall at the same rate in a vacuum.
Which is the correct sequence of stages in the water cycle?
Condensation → Evaporation → Collection → Precipitation
Collection → Precipitation → Evaporation → Condensation
Precipitation → Collection → Evaporation → Condensation
Evaporation → Condensation → Precipitation → Collection
The water cycle begins with evaporation, then condensation forms clouds, precipitation falls as rain or snow, and collection gathers water back into bodies like lakes and oceans.
Dry ice is carbon dioxide in solid form. When it changes directly from solid to gas, this process is called:
Sublimation
Freezing
Condensation
Melting
Sublimation is the conversion of a solid directly into a gas without passing through the liquid phase. Dry ice is a familiar example of this process.
What does the prefix "bio-" mean in scientific vocabulary?
Small
Water
Heat
Life
The prefix "bio-" comes from Greek and means "life," as seen in words like biology (the study of life) and biodiversity (variety of life).
What is the term for the process by which a seed begins to grow into a new plant?
Photosynthesis
Germination
Evaporation
Decomposition
Germination is when a seed absorbs water, swells, and begins to sprout under suitable conditions of temperature and moisture. This is the start of a plant's life cycle.
What causes day and night on Earth?
Earth's revolution around the Sun
The tilt of the Earth's axis
The Moon blocking the Sun
Earth's rotation on its axis
Earth's rotation on its axis causes different regions to face toward or away from the Sun, resulting in day and night over a 24-hour cycle.
Which instrument is used to measure the force applied to an object?
Ruler
Spring scale
Speedometer
Thermometer
A spring scale measures force by the extension or compression of a spring calibrated in newtons or other units of force.
Which surface condition will increase friction when an object slides over it?
A lubricated surface
A rougher surface
A wet surface
A smoother surface
Rough surfaces have more irregularities that resist motion, creating greater friction than smooth, wet, or lubricated surfaces.
Which statement correctly distinguishes mass and weight?
Mass depends on gravity, weight does not
Mass is measured in newtons, weight in kilograms
Mass is the amount of matter, weight is gravitational force
Mass changes with location, weight is constant
Mass is a measure of the amount of matter in an object and remains constant everywhere. Weight is the force due to gravity acting on that mass and can vary with gravitational strength.
In a simple pulley system with two pulleys (block and tackle) and no friction, if you lift a 100 N load, how much force do you need to apply?
200 N
100 N
50 N
25 N
A two-pulley block and tackle system gives a mechanical advantage of 2, meaning the input force required is half the load when friction is ignored.
Which process best describes water flowing down slopes into rivers after rainfall?
Runoff
Evaporation
Infiltration
Transpiration
Runoff is the movement of water over land surfaces into streams and rivers following rainfall, especially when the ground is saturated or impermeable.
Why is fire considered a non-living phenomenon rather than a living thing?
It reproduces
It grows
It needs energy
It has no cells
Living organisms are defined by cellular structure and life processes like reproduction. Fire lacks cells and does not carry out biological functions.
Which of these insects undergoes incomplete metamorphosis?
Butterfly
Beetle
Grasshopper
Ladybug
Incomplete metamorphosis involves three stages - egg, nymph, and adult - with the nymph resembling the adult. Grasshoppers follow this life cycle pattern.

Cheat Sheet

  1. Understand the Three States of Matter - Matter loves to play dress-up as solids, liquids, or gases depending on how much heat it's feeling. From ice cubes that clink in your glass to steam that fogs a mirror, these shifts happen when particles gain or lose energy. Dive into how melting, freezing, and evaporation work together in this molecular dance. BU Lesson on States of Matter
  2. Explore the Water Cycle - Imagine water on a never-ending adventure, wandering from oceans to clouds and back as rain or snow. Evaporation, condensation, and precipitation are the three key chapters of this story, and they keep our planet refreshed. Get ready to trace every drop on its thrilling trip through nature's recycling system! Twinkl: Water Cycle Facts
  3. Recognize Life Cycles in Plants and Animals - All creatures, from blooming flowers to buzzing bees, follow a step-by-step roadmap of birth, growth, and reproduction. Think of how a tiny caterpillar munches leaves, then spins a chrysalis before emerging as a colorful butterfly. Understanding these stages helps you appreciate every leap and flutter in the circle of life. VTaide's Sci-Cycles Guide
  4. Analyze Simple Experiments - Science is all about asking "what if?" and watching the magic happen. Mix baking soda and vinegar for a fizz-tastic reaction that releases carbon dioxide gas, or test how salt affects water's freezing point. These hands-on activities sharpen your observation skills and spark your inner scientist! NGSS: Structure & Properties of Matter
