Are you looking for a fun way to cover the human digestive system in your classroom?
Try this Fun hands-on activity for kids of grade 4.
Attainment Target: Describe the human digestive system including the functions of the organs involved (limited to mouth, oesophagus, stomach).
This Attainment target was achieved through an activity. Students learned the pathway of food as it travels through different organs of the body and gets broken down for nutrients and energy.
Materials:
You will need …
● banana
● two crackers
● plastic bowl
● fork
● water (50 ml)
● Ziplock bag
● orange juice (20 ml)
● one leg cut from a pair of tights
● Gloves
● paper towel
Students were able to see how food turns into a soup-like liquid in the stomach (the ziplock bag) which then passes into the intestines (the tights). Within the small intestine nutrients and water pass through the wall.The liquid that ends up in the plastic bowl should be milky, which shows how the useful chemicals the body needs have passed through the wall. The large chemicals, such as fibre stay inside the intestine and are eventually passed out when we go to the toilet.
