  1. There’s Energy in That Nut Hannah Rae Hendra 3rd Grade, Age 9 April 29, 2007 Misawa, Japan Scientific Investigation

  2. Objective • Determine how much energy is in various types of nuts through heating of water by burning the nuts • Perform similar experiment with marshmallows • Document results • Have fun Scientific Investigation

  3. Experiment Hypothesis • The brazil nut will burn longest because it is the largest. • Marshmallows will be comparable to the nuts. Scientific Investigation

  4. Research • Internet Google Search provided Several Different Experiment Types • Keywords: “Science Experiment Nuts” • 1,120,000 results in 0.11 seconds • Chose the following as a basis: http://www.woodrow.org/teachers/chemistry/institutes/1988/foodheat.html Scientific Investigation

  5. Search Results Scientific Investigation

  6. Procedure • Measure 50ml of water in beaker. • Pour the water into a metal measuring cup. • Measure the starting temperature of the water. • Position the nut under the water and light it. • Start the timer and watch for the nut to burn out. • Once the nut is done burning, stop the timer and record the temperature. Scientific Investigation

  7. Precisely Measuring The Water The Experiment (1) The Nuts Observing the Process Scientific Investigation

  8. The Experiment (2) Precisely Documenting Results Explaining the Experiment to Inquisitive Neighbors Scientific Investigation

  9. Experiment Results (1) Scientific Investigation

  10. Experiment Results (2) Scientific Investigation

  11. Experiment Results (3) Scientific Investigation

  12. Final Observations • The nuts burned for a long time. • The brazil nut burned the longest. • The marshmallows didn’t do much. • The brazil nut had the most energy. • The peanut had the least energy. • The size of the nuts varied. • This experiment was exciting. Scientific Investigation

  13. The Display Scientific Investigation
