Energy in Nuts Experiment

This experiment illustrates how to determine the energy value in food (NUTS). This experiment can be done to compare energy value in different food sources.
Topic: Energy value in nuts (food)
Aim: To determine which nut contains the greatest energy (or greatest energy per gram).
Method:
1. See the video for set up (stand clamp and nut on the T-pin).
2. Clean all apparatus.
3. Select at least three different nuts
4. Weigh each nut and record their masses (initial mass).
5. Measure and pour 20 mL of pure water in the test tube.
6. Measure the temperature of the water (initial temperature).
6. Place one of the nuts on the T-pin and ignite it over the Bunsen burner.
7. Position the nut so that the top of the flame touches the
bottom of the test tube.
8. Allow the nut to burn completely (or as the water reaches 100 degrees Celsius).
9. Take the final temperature of the water (maximum temperature reached).
10. Measure the unburnt nut (remains of the nut). This is the final mass of the nut.
11. Repeat the procedure with the other nuts (or the same kind of nut previously used).
*** See video content for calculations and useful explanations.

Thank you

[@phaedrakaithlyn]

One of the coolest experiments!!

[@science_exam]

Labs days were rough, but enjoyable.

[@christiniquerahming1957]

I really liked this experiment it kind of reminds me of chemistry when finding out the energy used by using the formula mc delta t. 👍🏽

[@science_exam]

The concept is definitely the same.

[@DrBetts]

I really enjoyed this video! What a great way to introduce calories/kJ

[@science_exam]

That's great. The students really love this experiment.

[@Silviamarc]

The video was great and it was very interesting to watch.

[@science_exam]

Thank you.

Do u have a write up of the lab

Hello. May you please share the equation of how to find energy of the substance in terms of kcal/g

[@science_exam]

Please note: 1 cal = 4.184 J
In the video I showed how to calculate in J and joules/g
What you need to do is find the energy in Joules then divide by 4.184, then divide by 1000 to get Kcal. Finally divide that answer by the mass of food burnt.

May i know the method to hold the food for pudding ?

[@science_exam]

That may be a difficult food to hold. However, try using a spatula or test tube holder or tongs.
