This cheat sheet helps grade 2 and grade 3 students learn important science words in clear, simple language. It is useful for reading science questions, talking about investigations, and remembering what common science terms mean. Students can use it as a quick guide during review, homework, or class practice. The guide focuses on four main science areas: science skills, matter, forces and motion, and living things with Earth science. Important ideas include using observations, sorting materials by properties, describing pushes and pulls, and understanding basic needs of living things. Simple word equations help students connect science words to real ideas, such as push plus pull equals force.
Key Facts
- An observation is information you get by using your senses, such as seeing color, hearing sound, or feeling texture.
- A property is something you can notice or measure about an object, such as size, shape, color, weight, or texture.
- Matter is anything that takes up space, and matter can be a solid, liquid, or gas.
- A force is a push or a pull that can make an object start moving, stop moving, speed up, slow down, or change direction.
- A simple word equation for motion is force plus object equals possible motion.
- A habitat is the place where a plant or animal lives and gets food, water, air, and shelter.
- Weather describes the air outside at a certain time and place, including temperature, wind, clouds, and rain.
- A life cycle shows how a living thing grows and changes, such as egg, young animal, adult animal.
Vocabulary
- Observe
- To observe means to use your senses to learn about something.
- Matter
- Matter is anything that takes up space, such as air, water, rocks, and toys.
- Force
- A force is a push or a pull on an object.
- Motion
- Motion is a change in an object's position.
- Habitat
- A habitat is the natural place where a plant or animal lives.
- Weather
- Weather is what the air outside is like at a certain time and place.
Common Mistakes to Avoid
- Mixing up observe and guess is wrong because an observation uses senses, but a guess is an idea that may need testing.
- Calling only heavy objects matter is wrong because light things, liquids, and gases also take up space and are matter.
- Saying a force always makes something move is wrong because a push or pull may be too small to move a heavy object.
- Confusing habitat with home is wrong because a habitat includes everything a living thing needs, such as food, water, air, and shelter.
- Using weather and season as the same word is wrong because weather can change each day, but a season lasts for months.
Practice Questions
- 1 A student observes 3 red leaves and 5 yellow leaves. How many leaves did the student observe in all?
- 2 A toy car moves 6 spaces forward, then 2 more spaces forward. How many spaces did it move in all?
- 3 Sort these items as solid, liquid, or gas: pencil, juice, air, rock.
- 4 A plant is not growing well because it has no sunlight. Explain why sunlight is important for the plant.
