  1. Food Glorious Food!

  2. Today’s Lesson • Finish Booklets • Introduction to Different Food Types • Measuring Energy • Starting Small Activity

  3. Booklets • We will now be making small booklets. Once the booklets are made, we need to complete the work below on the following pages: • Page 1: Grade 7 Science – Semester One (Heading) • Page 2 & 3: Tell me some things about yourself. Do you have any brothers/sisters, favourite movie, favourite sport, what you find annoying etc. • Page 4 & 5: Tell me what you enjoyed and did not enjoy about Grade 6 Science. • Page 6 & 7: What would you like to do/learn about in Grade 7 Science • Page 8: What are you going to try harder to do in Science this year?

  4. How do we get energy? • Get into Groups of 4. • There are 3 main types of energy found in our food. As a group, discuss what you think they are. • Try and include 2 examples of each (one healthy/one unhealthy) for the 3 main food types

  5. Why we need food? • Your body needs food for different reasons. They are: • For energy • For growth and repair • To stay healthy • Food can be broken down into three main types. They are: protein, carbohydrates and fats/lipids

  6. Proteins • Proteins are needed for growth and repair of cells. • Proteins are made up of amino acidswhich are broken down in digestion. • The broken down amino acids then can be made into specific amino acids the body needs.

  7. Carbohydrates • Carbohydratesare used for your immediate energy needs. • There are different types of carbohydrates such as sucrose, lactose, glucose and fructose. • Glucose, starch and glycogen are larger sugar molecules that can be made into smaller sugar molecules.

  8. Fats • Fats are used to store energy and to keep you warm. • Some fats are bad for you (picture above), but some fats are VERY good for you (below). • Good fats can be found in olive oiland avocado.

  9. Measuring Energy • Energy in measured in Joules. • Food is normally measured in kJ (or X1000 joules). • Different people require different amounts of energy, along with different amounts of nutrients Energy drinks may taste good – but they are normally not good for you!

  10. Vitamins & Minerals • You need small, regular amounts of vitamins and minerals to stay healthy. • Examples include Vitamin A, B1, C, D, iron, calcium & iodine

  11. Energy from Different Foods • Different foods provide different amounts of energy. For example: • 1 gram of pure carbohydrates = 16 kj • 1 gram of pure protein = 16 kj • 1 gram of pure fat/lipids = 32 kj http://www.onestoptreatment.com/tag/energy-packed-foods/

  12. Working Out Amounts of Energy • Often, Nutrition Labels show us information in 100 grams. However – we don’t normally eat exactly 100 grams of a specific food (100 grams of oil anyone??) • So – how can we work out how much food there is if we eat 50 or 200 grams??

  13. An Example • Food 1. • Carbs = 20 grams per 100 grams • Fat = 6 grams per 100 grams • Protein = 12 grams per 100 grams. • How much energy is released if I eat 200 grams? • Which energy type will provide us with the most energy on this occasion?

  14. Our Activity • OK GOOGLE DRIVE LOVERS!! We are now going to use our laptops (yay – not!!). • Open up a new google spreadsheet. • Label it (YourName)Food and share it with me! • Copy and paste the information from my google spreadsheet (it’s been shared with you) • We will also make a second page for practice (look at my doc)

  15. Continued • Choose 6 different foods that students want to eat! Write them down onto the practice page • Then search “Food Name” Nutrition Facts on Google Images for the amount of protein, fat and carbohydrates found in grams for each food. • Listen for further instructions…….
