Experiment: Food energy value

Energy value of food sample can be determined by doing simple experiment in the Lab...Its a simple calorimeter bomb...And that was what we were doing last week.

The form 4 helpilia girls were conducting the experiment @ Bio Lab. they were investigating the two types of nuts : ground nut and cashew nuts. They want to compare which of the two nuts has higher energy value :

So the AIM of the investigation is : To determine the energy value of the food samples/ different nuts

Problem Statement: Does cashew nut has higher energy value than ground nut ?

Hypothesis : Different type of nuts has different energy value .

OR Cashew nut has a higher energy value than ground nut

OR you can even construct the sentence based on the experiment, such as :

CASHEW NUTS SHOWS A HIGHER INCREASE IN WATER TEMPERATURE THAN GROUND NUT..

Variables:

Manipulated : Type of nuts

Responding : the final water temperature // energy value

Fix : the initial temperature

// the mass of nut

Apparatus and Materials : List down ALL

Technique : To measure and record the final water temperature using thermometer.// To calculate......................................................

Procedure :

Result :

Discussion: (If for PEKA)

Conclusion:

...You can try out to design this experiment (Question 2 Paper 3 )

**My students did this experiment for PEKA...
