Question 1: What is the very first step of the scientific method?
- Testing a hypothesis
- Asking a question
- Writing a report
- Making an observation
Answer: D. Making an observation
Explanation: The scientific method begins by using your senses to make an observation about the world, which helps you notice things that need further study.
Question 2: Which of these is one of the five senses used for observations?
- Thinking
- Dreaming
- Running
- Hearing
Answer: D. Hearing
Explanation: The five senses used to explore the world are sight, hearing, smell, taste, and touch. Hearing is one of these essential tools.
Question 3: What do you do after making an observation?
- Finish the experiment
- Draw a picture
- Clean the lab
- Ask a question
Answer: D. Ask a question
Explanation: After you observe something, the next step is to ask a question about why or how that thing happens in the world.
Question 4: What is a testable prediction or educated guess called?
- A hypothesis
- A conclusion
- A result
- An observation
Answer: A. A hypothesis
Explanation: A hypothesis is a specific, testable prediction that states what you think will happen if you take a certain action.
Question 5: What is the fourth step of the scientific method?
- Making an observation
- Asking a question
- Conducting an experiment
- Reporting results
Answer: C. Conducting an experiment
Explanation: The fourth step is to conduct an experiment to test your hypothesis by changing one variable and measuring the outcome.
Question 6: What do scientists use to record their findings?
- A notebook or chart
- A telescope
- A magnifying glass
- A calculator
Answer: A. A notebook or chart
Explanation: Scientists use tools like notebooks or charts to carefully record their findings and observations during an investigation so they can remember them.
Question 7: What is a common experiment for first graders?
- Measuring the speed of light
- Studying distant stars
- Building a rocket ship
- Testing if objects sink or float
Answer: D. Testing if objects sink or float
Explanation: Testing which objects sink or float in water is a classic, simple experiment used to help students understand basic scientific concepts.
Question 8: What do you do after an experiment is complete?
- Change the question
- Forget the data
- Draw conclusions
- Start a new experiment
Answer: C. Draw conclusions
Explanation: Once the experiment is done, you draw conclusions by recording your results and explaining what the data you collected actually means.
Question 9: What is the final step of the scientific method?
- Making a hypothesis
- Conducting an experiment
- Communicating the results
- Asking a question
Answer: C. Communicating the results
Explanation: The final step is to report or communicate the results of your investigation to others so they can learn from your work.
Question 10: Which is an example of a scientific observation?
- Running in the playground
- Reading a storybook
- Noticing ice melts faster on metal
- Eating a healthy lunch
Answer: C. Noticing ice melts faster on metal
