There’s Energy in That Nut Hannah Rae Hendra 3rd Grade, Age 9 April 29, 2007 Misawa, Japan Scientific Investigation
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
Experiment Hypothesis • The brazil nut will burn longest because it is the largest. • Marshmallows will be comparable to the nuts. Scientific Investigation
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
Search Results Scientific Investigation
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.
