Scientific Investigations: Parts of an Experiment
Question: What am I trying to find out?
Hypothesis: What do I guess is the answer to my question?
Materials: What objects do I need to complete this experiment?
Procedures: What steps do I need to do to complete this experiment?
Constants: Things I need to keep the same; things I will not change
Independent variable(s): What am I changing in the experiment?
Dependent variable(s): What happens because of the changes I made to the experiment?
Observation: What do you see, feel, taste, hear, and smell when I do the experiment?
Conclusion: What did you learn in the experiment? What is the answer to your question?
" Cut out the boxes below. Match each part of the experiment below with the correct example and glue them into your notebook.
Question / I notice/see that the ball is bouncing higher when I drop it from a greater height.Hypothesis / I need a tennis ball, a pencil, tape, and a paper meter stick
Materials / 1) First, tape the paper meter stick to the wall.
2) Second, drop the tennis ball from a height of 30 cm.
3) Third, draw a line on the paper meter stick where the ball bounced.
Procedures / I will change the height that I drop the tennis ball from 30 cm to 60 cm.
Constants / If I increase the height that I drop a tennis ball from, then it will bounce higher.
Independent variable(s) / I learned that a tennis ball will bounce higher if I increase the height that I drop the ball from.
Dependent variable(s) / Will a tennis ball bounce higher if I increase the height that I drop it from?
Observation / The height that the tennis ball bounced changed because I changed the height that I dropped the tennis ball from 30 cm to 60 cm.
Conclusion / I will use the same tennis ball each time I drop the ball.
