Abstract

This science fair project was done to find out whether nuts are able to store energy. Given that they are able to, what is the energy storage capacity of different types of nuts? For this experiment, peanuts and a cashew nut were used.

Hypothesis

The first hypothesis is that nuts are able to store energy. Our second hypothesis is that the cashew nut will have a higher energy storage capacity than the peanut.

Scientific Terms

Protein, carbohydrate, Omega-3 fatty acid, iron, potassium, amino acid, copper

Background

Nuts

Normally, a nut has a hard outer shell that shelters the edible inner part. This inner part is essentially a seed which is edible. Nuts are a rich source of protein. Unlike carbohydrates, proteins do not supply us with sharp and quick bursts of energy. Instead, it provides a slow but long lasting supply of energy.

Different types of nuts provide different kinds of nutritional benefits. Almonds, for example, contain many proteins. They are also rich in iron and potassium. Cashew nuts contain many kinds of amino acids, and copper. Walnuts contain many kinds of Omega-3 fatty acids. These acids serve as a source of energy for our organs and muscles.

Nuts can be eaten raw. They can also be roasted or cooked alongside other dishes. Nuts contain certain kinds of oils, and these can be extracted to make cooking oil or for other uses, including manufacturing of cosmetics. Wild animals depend on nuts for food. Animals such as squirrels collect nuts during autumn, storing them away for winter.
