The Food Guide Pyramid




How to plan our meals


The food guide pyramid is a useful way to plan our meals in a healthy way.
 It helps us to choose healthy food and shows how much to eat of each type of food every day.


Online activities







Exercise helps our muscles and our heart. It also makes us flexible. We should try to do some exercise every day because it makes us healthy and look and feel better.



Exercise Safely


If we don't exercise carefully we can break a bone or hurt a muscle.




Warm up to prepare your muscles and prevent muscle injury.




Choose an appropiate and safe place to exercise, like a tennis court to play tennis.

When you sweat you lose liquids. Drink water fifteen minutes before exercise and then every twenty minutes.

Wear appropiate safety equipment for the exercise you are doing, like a helmet or knee pads.



Wear comfortable shoes. These will help you avoid injury to your feet.

Stretch after exercise. Hold each stretch for about 30 seconds. Stretch and breathe slowly.




Germs are very small living things that can only be seen under the microscope. When they enter our body they consume nutrients and produce toxins. Toxins can cause disease. Many diseases caused by germs spread from person to person.


We can avoid germs by:


1. Washing our hands before eating, after using the bathroom and after sneezing or coughing.


2. Brushing our teeth after every meal.


3. Not putting things in our mouth.


4. Covering our nose and mouth when we sneeze or cough.



We need to rest and sleep


After we study or play our body needs to recover. We need to sleep every night. When we sleep our body slows down and uses less energy so it can repair itself. Too little sleep affects growth and our immune system.
