The water experiment we did - Describe briefly the water experiments you did - Describe briefly the food test experiments you did. The starch test  Purpose: which food doesn’t have starch : bread, potato, orange, or apple? Tools: plates, potato, orange, apple, IODINE SOLUTION, a dropper  In conclusion we saw that the food with the least starch is orange because the iodine solution didn’t sink in and change color on the other hand apples, potato and bread did sink in and change colors.

 What are the main questions of your survey?    - Describe the survey data (Percentages)?   - What did you conclude from the survey?  { Are people aware of following healthy diet? Do teenagers eat healthy food? } - Describe the interviews you did with students/ people about the healthy diet.    We concluded that the community is well educated about water properties, carbohydrates, lipids, and proteins. Although not all completely our aim is to now educated everyone.     

 Nowadays teenagers are increasingly turning to unhealthy diets to lose or gain weight and build muscles, ignoring the importance of balanced daily meals

Describe the water molecule: A water molecule consists of 2 hydrogen atoms bonded to an oxygen atom, and its overall structure is bent.                                                The properties of water                           Water is  cohesive  because water molecules stick together. Water is adhesive because water molecules tend to attract to other  substances. Water has high surface tension because water is extremely cohesive, and it is difficult to break the surface of water. Water is good at capillary action because its cohesive and adhesive. Water has high heat capacity because the amount of heat energy required to increase water's temperature is relatively high.               Ice is less dense than liquid water because water expands slig...

  Lipids Fatty acids and Glycerol are the monomers for lipids  Lipids are composed of carbon, hydrogen, and oxygen atoms, and in some cases contain phosphorus, nitrogen sulfur, and other elements. Types of lipids: Triglycerides They are the main form of lipids in plants and animals Example: Avocado, oil, meat, nuts, butter, and etc.. Phospholipids Example: Cell membrane is a phospholipid bilayer Waxes Example: Beeswax, earwax, and cuticle of leaf Steroids  Example: Cholesterol, Hormones, And Vitamins     Lipids are important in the diet because they are energy sources and as sources of fatty acids. They also serve as structural components of cell membranes. 20-35% of our food intake should be from lipids Lab Report test station 4:  For this experiment we wanted to see which food has the most amount of lipids, so we had 4 test tubes and in test tube 1 we put 10 drops of water, in test tube 2 we put 10 drops of milk, in test tube 3 we put 10 drops of soda, an...

 Carbohydrates  Hydrocarbons • Compounds that contain only carbon and hydrogen are called hydrocarbons. • Carbon often forms nonpolar covalent bonds with hydrogen. • We often use hydrocarbons in our daily life as fuels: Propane in a gas grill- Butane in a lighter are both hydrocarbons. • Methane (CH4) , the simplest hydrocarbon molecule, consists of a central carbon atom bonded to four hydrogen atoms. What are Carbohydrates? • Carbohydrates are organic compounds of carbon, hydrogen and oxygen. • The general chemical formula of Carbohydrates is (CH2O)n or CnH2nOn • Carbohydrates have a ring like structure. • Most carbohydrates are hydrophilic and soluble in water. • Carbohydrates are found in living tissues and foods in the form of starch, cellulose, and sugars. Carbohydrates Functions 1. Carbohydrates are used as a short-term energy source. Cells break down carbohydrates (glucose) to produce ATP energy molecules quickly. 2. Carbohydrates provide structural support to cells. Th...

                                                              Proteins Structure: Proteins are macromolecules containing carbon, hydrogen, oxygen & nitrogen.  -  Why do we need to eat proteins? Protein is an important part of a healthy diet. Proteins are made up of chemical ‘building blocks’ called amino acids. Your body uses amino acids to build and repair muscles and bones and to make hormones and enzymes. - How much proteins should we eat daily? Anywhere from 10% to 35% of your calories.   Proteins have structure functions - Enzymes are Proteins - Some Hormones are proteins.  Proteins are made up of Amino Acids that are connected by peptide bonds.  They’re 12 Amino Acids in your body 8 you must get from food. Amino acid is made up of  3 parts (Amino group, Carboxyl group and R group) There are ma...
