What do you observe from the graph about the water temperature?
Do all the nuts have same level of energy?
Does the increase of temperature among the three types of nuts is the same?
From the graph, which type of nut produces the highest energy?
Arrange the food sample according to its energy in ascending order.
Is your result accurate? Does all the energy from the nuts is used to heat the water or some heat is lost? How could this affect your results?
Do you eat to live OR live to eat???
OR eat to live live to eat
Many will say they eat to live because it is necessary to sustain life and as a respond to hunger. They eat in order to obtain the strength to carry on life's daily activities.
However, there are also people who live to eat. They love to eat and they crave food of any and every kind. Live to eat is a habit of enjoying eating. This kind of people can easily suffer from obesity.
My advise is we should eat to live, don’t live to eat.
Unique Features of This Activity
the temperature can be recorded every second
the temperature can be recorded in three decimal places
the setup of the apparatus is quite simple and we only need a test tube and a temperature sensor to test the energy of the nuts
the experiment gives only a very approximate estimate for each foodstuff, so the students can use any type of food to replace the nuts and calculate the food energy.
students can compare the graphs and differentiate the energy between the three types of nuts
