Balanced Food Groups & Teeth
3. Why should we brush our teeth for two minutes twice a day with fluoride toothpaste and limit sugary snacks: bacteria in plaque feed on sugar and make acid that causes tooth decay (cavities), or brushing makes teeth softer?
Balanced Food Groups & Teeth

Balanced Food Groups & Teeth
11. Which hard framework inside your body supports your weight, gives your body its shape and protects vital organs like the brain and heart: the skeleton (bones) or the skin?
Balanced Food Groups & Teeth

Food groups, teeth & keeping healthy

Answers and reasoning. Review before teaching.

1. Why do our bodies need to eat a balanced diet of different foods and drink plenty of water every day: for energy, growth and staying healthy, or to change our eye colour?
For energy, growth and staying healthy
Food supplies fuel for movement and warmth plus the building blocks for growing bones, muscles and organs.
2. Why do children and teenagers need a good night’s sleep every night: the brain consolidates learning and memory while the body repairs tissues and releases growth hormone, or sleep wastes energy?
The brain consolidates learning and memory while the body repairs tissues and releases growth hormone
Adequate sleep is essential for concentration, immune health and physical growth.
3. Why should we brush our teeth for two minutes twice a day with fluoride toothpaste and limit sugary snacks: bacteria in plaque feed on sugar and make acid that causes tooth decay (cavities), or brushing makes teeth softer?
Bacteria in plaque feed on sugar and make acid that causes tooth decay (cavities)
Brushing removes plaque and protects the hard outer enamel of the teeth.
4. Which sharp, chisel-shaped teeth at the very front of your mouth are designed for biting and cutting into food like an apple: incisors or molars?
Incisors
The eight front incisors have flat, sharp edges for biting off pieces of food.
5. What should you do when you sneeze or cough to stop germs spreading through the air to classmates: cover your nose and mouth with a tissue or the inside of your elbow, then wash your hands, or sneeze into the fan?
Cover your nose and mouth with a tissue or the inside of your elbow, then wash your hands
Catching droplets in a tissue or elbow prevents airborne transmission of cold and flu viruses.
6. Which mineral found in milk, yoghurt, cheese, tofu and leafy greens helps build strong bones and teeth: calcium or helium?
Calcium
Calcium gives bones and tooth enamel their strength and hardness.
7. Why does the body sweat when you exercise on a warm day: as sweat evaporates from the skin, it carries away heat energy and cools the body down, or sweat warms the skin?
As sweat evaporates from the skin, it carries away heat energy and cools the body down
Evaporative cooling helps keep core body temperature near 37 °C.
8. What is the first set of 20 temporary teeth that young children grow before their adult teeth come through: milk teeth (baby/deciduous teeth) or wisdom teeth?
Milk teeth (baby/deciduous teeth)
Children’s milk teeth gradually fall out from around age 6 to make room for 32 permanent adult teeth.
9. What is the hardest substance in the human body, which forms the protective outer coating of each tooth: tooth enamel or fingernails?
Tooth enamel
Enamel is a mineralised layer covering the crown of each tooth.
10. How does dietary fibre (found in wholegrains, oats, beans, fruits and vegetables) help our digestive system: it keeps food moving smoothly through the intestines, or it turns into bone?
It keeps food moving smoothly through the intestines
Fibre adds bulk and prevents constipation, supporting a healthy gut.
11. Which hard framework inside your body supports your weight, gives your body its shape and protects vital organs like the brain and heart: the skeleton (bones) or the skin?
The skeleton (bones)
The human skeleton supports the body, protects organs and works with muscles to allow movement.
12. Which mineral found in spinach, lentils, beans and red meat is needed by red blood cells to make haemoglobin and carry oxygen: iron or sodium?
Iron
Iron is a core component of haemoglobin in red blood cells.
