Scientific Method
What step of the scientific method is it when you use your five senses to gather information about the world around you?
Observation
Which state of matter keeps its own fixed shape and volume, like an ice cube, a rock, or a wooden block?
Solid
What types (more than one) of energy does a lamp have?
Light, Thermal, Electrical, Sound (sometimes)
What handy navigation tool uses a tiny magnetic needle to help travelers find their way by always pointing toward magnetic North?
A compass
What process do green plants use to make their own food using sunlight, water, and air?
Photosynthesis
What tool would a student use to measure the mass of a rock in grams?
Balance/ Scale
Which state of matter flows and takes the exact shape of whatever container you pour it into?
Liquid
What kind of energy does an object have because it is in motion, like a rolling bowling ball or a running dog?
Kinetic Energy
What part of the water cycle brings water back down to Earth's surface in the form of rain, snow, sleet, or hail?
Precipitation
What do scientists call an animal that gets its energy by eating only plants, such as a deer, rabbit, or caterpillar?
Before starting an experiment, a scientist makes an "educated guess" about what they think will happen. What is this called?
Hypothesis
What evidence of a chemical change do you see when you mix baking soda and vinegar together in a cup?
Bubbling, Fizzing, or Gas formed
What form of energy travels in waves through the air and lets us hear things like music, talking, or a ringing bell?
Sound energy
What giant layer of air and gases surrounds the Earth like a protective blanket, giving us air to breathe and protecting us from outer space?
Earth's Atmosphere
What term describes a plant or animal species that is in danger of going extinct because its population has dropped very low?
Endangered
During an experiment, a scientist writes down numbers, measurements, or drawings in a notebook. This information is called:
Data
Why is burning a piece of paper into ash considered a chemical change rather than a physical change?
Because a new substance is created (ash/smoke) and it cannot be undone (it is irreversible).
What force works against motion when two surfaces rub together, like sliding your sneakers across a rug or applying bicycle brakes or rubbing your hands together?
Friction
What is the difference between Earth's rotation and revolution?
Rotation: Spins and causes night and day. It takes 1 day or 24 hours.
Revolution: Revolves around the sun and causes seasons. It takes 1 year or 365 days.
What invisible gas do green plants take in from the air during photosynthesis that humans and animals breathe out?
Carbon Dioxide
Why do scientists often do the exact same experiment three or more times?
To make sure their results are reliable/trustworthy
What special scientific word describes a "helper" substance that speeds up a chemical reaction without being used up itself?
Catalyst
Why does a bowling ball require a stronger push to start rolling than a tennis ball?
Because the heavier ball has more mass, requiring more force to move or change its motion.
What is it called when light bends as it passes from one material to another?
Refraction
What broad group includes animals with a backbone or spine, such as fish, amphibians, reptiles, birds, and mammals?
Vertebrates
