Grade 3 and 4 Science Topics MAP review

What is the difference between observation and inference?

• Observation is what you perceive using your senses, while inference is a conclusion or interpretation based on observations.

• Observation and inference are interchangeable terms

• Observation is the same as inference

• Inference is based on emotions, while observation is based on facts

Explain the steps of the scientific method.

• Skip data analysis step

• Conduct experiments before formulating a hypothesis

• The steps of the scientific method are: 1. Make an observation, 2. Formulate a hypothesis, 3. Conduct experiments to test the hypothesis, 4. Analyze the data, 5. Draw conclusions, and 6. Communicate results.

• Make a hypothesis without observation

Give an example of how living things can be classified.

• Based on their ability to fly.

• Based on physical characteristics such as size, shape, color, and structure.

• Based on their favorite food.

• Based on the number of legs they have.

What are the three states of matter?

• plasma

• solidus

• vapor

• solid, liquid, gas

Describe the relationship between energy and motion.

• Energy is required to initiate and sustain motion.

• Motion can occur without any energy input.

• Energy and motion are completely unrelated concepts.

• Energy is only needed for motion in certain situations.

How do Earth's systems interact with each other?

• By following linear cause and effect relationships

• Through isolated and independent processes

• Through random and unrelated occurrences

• Through complex feedback loops and interconnected processes

Why is observation important in science?

• Observation is not important in science

• Scientists can rely solely on theoretical models without observation

• Observation leads to biased results in scientific research

• Observation helps scientists collect data and make informed conclusions.

How can you test a hypothesis in an experiment?

• Guess randomly without any data

• Use a magic eight ball for answers

• Ask a friend for their opinion

• Design a controlled experiment, collect data, analyze the data, and draw conclusions.

Name three different classifications of living things.

• Archaea, Bacteria, Eukarya

• Prokaryotes, Fungi, Protists

• Plants, Animals, Minerals

• Invertebrates, Vertebrates, Mammals

What happens to matter when it changes states?

• It disappears completely.

• It turns into energy.

• It becomes a new element.

• It undergoes a physical change.
