This project shows good hands-on effort in building and testing a simple circuit with different switches. The student demonstrates basic understanding of how materials affect whether a bulb lights. The project would be strengthened by more structured testing, repeated trials, and quantitative measurements such as voltage or current. Adding clearer engineering success criteria would also improve the investigation. Overall, this is a solid Grade 4 engineering exploration with room for deeper analysis.
Fantastic job building something real and testing it in a fair way! Your project is clear, your flashlight worked, and your results matched your hypothesis. If you repeat the test a few times and average the results, your next project will be even more “scientist strong.” Keep it up!
Great job building your own working flashlight and carefully comparing flat and curved reflectors to test how the shape affects the distance of the light beam. I liked that you collected real measurements and showed that the curved reflector helped the beam travel farther, which clearly supported your hypothesis.
good job
