Explaining certain subjects in the classroom is not always easy. You can help yourself with books and drawings easy trivia questions, but for children to understand what the human body is and how it works without seeing what its interior is like is quite a challenge.
For this reason, we are going to help teachers and parents with some fun activities and easy trivia questions with which the children will learn where they are, how the organs work and what they need to grow and stay healthy.
1. Cerebral hemisphere:
What is each of the hemispheres of the brain like? What functions does it house? Answer these questions by turning an old helmet or cap into a brain to use in class to explain to children how it works.
To make it easier, you can download the template of the brain areas. Once printed it only remains to fix it to the helmet with a little white glue. It is an activity that will surprise children and make it very easy for them to see which area of their brain is activated by language, music or calculation.
2. Respiratory system:
It is not the same to talk about how air enters and passes through the larynx, trachea and bronchi until it reaches the lungs, for children to see the respiratory process in a practical way. Try doing it through this craft with recycled objects such as plastic bottles, cardboard, balloons, straw and adhesive tape.
The experiment consists of making a hole in the cap of the bottle through which two straws will come out, which, once inserted in the bottle, will end in two balloons. To put the elements in the bottle, cut it off at the base and close it with another balloon.
If the children pull the elastic part of the base, they will get more air in, causing the balloons (representing the lungs) to inflate, or less, and the homemade lungs to deflate.
3. Make your own digestive system:
Tell students what happens to food from chewing it to leaving the stomach with an activity where they will learn the work of the digestive system. To do this ask them to crumble some bread, as they would chew. The food then drops down a cardboard tube into a zip-lock bag. Once at the bottom, add a little warm or carbonated water, which represents the games that are in the stomach. If you mix the whole with your hands, you will see how, little by little, the bread begins to unravel, a process similar to that which occurs in our stomach.
4. Felt the human body:
No matter how many illustrations students see, it is best to create a full-scale human body in which they know where each of the internal organs is located. You can use white felt to cut out the silhouette of one of the children. With colored felt make both the fundamental parts of the skeleton and the internal organs.
The result will be more fun if you put a bit of double-sided Velcro on the pieces so that the children can stick it on their human figure or, if you dress them in cotton garments, place them on their own body and discover where certain bones are, the heart, lungs, or digestive system
