I need an idea for a science experiment

Click For Summary
SUMMARY

The forum discussion centers around selecting a science experiment for a 10-year-old girl participating in a science fair. Key suggestions include the Mentos and Coke eruption experiment, which involves measuring the height of the eruption while controlling variables like the amount of Coke and temperature. Other proposed experiments include using bicarbonate and vinegar in a canister, growing a plant under different lighting conditions, and observing the reaction of sodium in water. The emphasis is on ensuring the experiment is engaging and educational, fostering a positive association with science.

PREREQUISITES
  • Basic understanding of scientific method and experimentation
  • Knowledge of variable control in experiments
  • Familiarity with simple chemical reactions (e.g., vinegar and baking soda)
  • Ability to measure and record data accurately
NEXT STEPS
  • Research the chemical reaction between Mentos and Coke for detailed methodology
  • Explore plant growth experiments under varying light conditions
  • Investigate the properties of sodium and its reactions with water
  • Learn about the scientific method to structure the experiment effectively
USEFUL FOR

This discussion is beneficial for parents, educators, and students looking for engaging science experiment ideas that are age-appropriate and educationally valuable.

My daughter is entering a science fair competition in 3 weeks. I'm helping her with her experiment.

She is 10 years old, in 4'th grade and about average to slightly less interested in science. I'm trying to come up with an idea that meets the following criteria...

I want it to be at a level where she can do it, maybe with a little help. Not so difficult that I wind up doing it while she watches.

It needs to be something that a 10 year old girl will find interesting and fun. I want her to have fun memories associated with science so that she learns to like it.

It needs to address a real question with an experiment to find an answer. A demonstration is not an experiment.

Any ideas?

Here are some ideas that might get you going,
-Mentos in coke, measuring the height of the eruption, working out the energy contained by the mentos, repeat with varying masses of mentos, remembering to keep variables such as the amount of coke constant and temperature.
-You can also try Bi-carb and vinegar in a canister
-Grow a plant in different conditions, (different lighting conditions)
-Sodium in water


Let me know if youd like some more ideas
Thanks,
Z.C
