Children learn about the different components of blood. They learn that red blood cells carry oxygen, white blood cells fight infection, platelets help to prevent bleeding, and that plasma is the medium in which these components are suspended. Children describe the functions of red blood cells, white blood cells, platelets and plasma, and create a pie chart showing the percentage of each component by volume in a typical sample of blood.
Children learn that the human circulatory system is composed of 2 parts - the systemic circulation and the pulmonary circulation. They learn about the role of the heart, blood vessels, and the components of blood such as red and white blood cells, platelets and plasma. In the writing frame provided, children create an information text on the human circulatory system using what they have learned.
Children learn that the human heart is a vital organ. They learn how blood flows through its double pumps system to the lungs and all around the body, supplying oxygen and removing waste products. They create their own 8-part explanation text, showing how blood is pumped around the body. They cut and paste, or write their own descriptions.
Children learn to measure their heart rate in beats per minute (bpm) by taking their radial pulse. They take and record their resting heart rate, then perform a vigorous exercise and measure their heart rate afterwards at an interval of 1 minute for 8 minutes. Children record their results in a table and transfer them to a line graph. Children interpret their results, discussing how their heart rate changed over time and why.
Children learn about the active ingredient in alcoholic drinks (alcohol or ethanol), and that the strength of a beverage can be measured as the percentage alcohol by volume (% ABV). They learn about the short and long-term effects of alcohol consumption. Children look at 16 different servings of different alcoholic drinks. Using the serving size and %ABV, they calculate how much alcohol (in ml) and how many units of alcohol are in each beverage. They place the beverages in order of strength. Children discuss why people drink alcohol if it has negative health effects.
Children learn that smoking involves inhaling tobacco smoke which contains the active ingredient, nicotine. They learn about the many health issues associated with smoking, such as cancer, heart damage, lung damage, and reproductive damage. They learn about other negative effects such as the unpleasant smell, high cost, and effects on the skin. Children carry out a survey, using a tally chart to find out the worst side effect of smoking. They transfer their results to a bar chart and place the negative effects in order of concern.
Children learn that our bodies are constantly using energy, and that we get all of our energy from food. They learn that we can store excess foor energy in our bodies in the form of fat deposits to help us in times of starvation. Children look at 6 different people profiles. They calculate whether each person is eating the right amount of food, and suggest ways in which they can improve their lifestyles.
Children learn about the many benefits of physical exercise, and identify some aerobic exercises. Children carry out a survey, identifying the most popular forms of exercise in their class or school. They record their results in a tally chart, displaying their results in a horizontal bar chart. They identify the most popular forms of exercise and suggest ways in which they can be promoted in school.
