 Ex: table salt (NaCl)
Water!
 Water’s ability to dissolve other chemicals is one of ____________________________________
 When a material dissolves into tiny pieces, it can ___________________________________
Other important chemicals
 Carbohydrates, fats, and proteins
 ___________________________________: are sugars and starches.

___________________________________ are used to sweeten foods and drinks; fruits and vegetables
also contain sugar

___________________________________ are found in foods such as bread and rice

Plants use the ___________________________________to make carbohydrates from carbon dioxide
and water

Carbohydrates are like ___________________________________–they provide energy
Fats
 Fats are also ___________________________________.
 They store ___________________________________that are released when they are broken down
 Fats are found in ___________________________________
 Fats are related to ___________________________________
Proteins
 Proteins are another type of ___________________________________ needed for life
 Meats such as ___________________________________contain large amounts of protein
 Like fats and carbs, proteins also ___________________________________to living things
 Proteins help control ___________________________________, like hear rate
 Proteins are the ___________________________________
Protein
 Protein chains fold into ___________________________________
 Proteins with different shapes ___________________________________
 If a protein twists into the wrong shape or has a missing part, ___________________________________.
 DNA (deoxyribonucleic acid) contains the code that’s needed to produce __________________.
 The code is carried out by ___________________________________
Importance of Nutrients
 Your body must get a regular supply of ___________________________________from the food that you eat in
order to function properly
 In addition to these chemicals, your body also needs ___________________________________.
 ___________________________________ are natural substances that your body needs to work properly

KEY
 Water
 The liquid of life…
 Demos
 Observe the following:

Substance 1 in water

Substance 2 in water

Substance 3 in water
 Results
 Observe the following:

Sugar in water- dissolves

Salt in water-dissolves

Food coloring in water-dissolves
 What does dissolve mean?
 to make a solution of, as by mixing with a liquid
 Ex: table salt (NaCl)
 Water!
 Water’s ability to dissolve other chemicals is one of the most important properties
 When a material dissolves into tiny pieces, it can move more easily from cell to cell
 Other important chemicals
 Carbohydrates, fats, and proteins
 Carbohydrates: are sugars and starches.

Sugars are used to sweeten foods and drinks; fruits and vegetables also contain sugar

Starches are found in foods such as bread and rice

Plants use the energy from sunlight to make carbohydrates from carbon dioxide and water

Carbohydrates are like fuel for your body –they provide energy
 Fats
 Fats are also fuel chemicals.
 They store larger amounts of energy that are released when they are broken down
 Fats are found in meats, butter, and cheese.
 Fats are related to oil
 Proteins
 Proteins are another type of chemical needed for life
 Meats such as beef and chicken contain large amounts of protein
 Like fats and carbs, proteins also provide energy to living things
 Proteins help control body activities, like hear rate
 Proteins are the basic part of human cells
 Protein
 Protein chains fold into a particular shape to carry out a particular function
 Proteins with different shapes carry out different functions
 If a protein twists into the wrong shape or has a missing part, it may not be able to do its job.
 DNA (deoxyribonucleic acid) contains the code that’s needed to produce protein.
 The code is carried out by RNA
 Importance of Nutrients
 Your body must get a regular supply of fats, proteins, and carbohydrates from the food that you eat in order to
function properly
 In addition to these chemicals, your body also needs minerals and vitamins.
 Minerals are natural substances that your body needs to work properly
 Vitamins are used in your body for growth and activity
 Nutrients are chemicals that come from foods that are needed for life
