Detailed Lesson Notes

The Human Body is Mostly Water

Explain to students that our bodies are made up mostly of water. Water is inside us and helps our body parts work well. Use a simple model or picture of the body to show water inside. Water helps keep us healthy by helping our heart, brain, and muscles work properly.

Why Drinking Water Daily is Important

Discuss with students that because our bodies have so much water, we need to drink water every day to stay healthy. Drinking water helps us stay strong, keeps our skin soft, and helps us not feel tired. When we play or run, we lose water through sweat, so we need to drink more water to replace it.

Understanding Healthy Portion Sizes

Introduce the idea of portion sizes by showing pictures or actual small amounts of food. Explain that eating the right amount of food helps our body get the energy it needs without eating too much. Use measuring cups or plates to show what a healthy portion looks like for common foods like fruits, vegetables, and grains.

Connecting Water and Healthy Eating Habits

Help students understand that drinking water and eating healthy portions work together to keep our bodies healthy. Encourage them to choose water instead of sugary drinks and to eat balanced meals with the right portions.

Common Misconceptions to Address

Some children might think that drinking juice or soda is the same as drinking water. Clarify that water is the best drink for our body. Others may believe that eating a lot of food is good; explain that eating too much can make us feel tired or sick. Reinforce that healthy portions and water help us feel our best.

Worked Examples

Worked Example 1

Scenario

If a student drinks water every day, what happens to their body?

Explanation

Drinking water every day helps the body stay healthy because the body is mostly made of water. Water helps the heart, brain, and muscles work well and keeps the body strong.

Answer Guide

The student's body stays healthy and strong because water helps all the parts work well.

Worked Example 2

Scenario

Show a picture of a plate with a small portion of fruit and a large portion of fruit. Which one is a healthy portion size and why?

Explanation

The small portion is healthy because it gives the right amount of food the body needs without eating too much. Eating too much can make the body feel tired or sick.

Answer Guide

The small portion is healthy because it is the right amount to eat.
