The next part of our Human Body Unit, is learning about the Digestive System and Nutrition.
If you missed the other parts of our Human Body Study, you can see them here: Human Body – Doctor’s Bag, Human Body ~ Body Parts, Human Body: Bones, Joints and Muscles, Senses, Cells, Heart, Blood and Circulation, Digestive System and Nutrition, the Brain and Nervous System, the Skin, Hair and Nails, the Immune System and Germs, the Respiratory System, the Excretory System, Reproduction System and Dental.
To learn about how the digestive system works, we did a little activity that included some water, biscuits and a zip lock bag.
For this activity, we placed a couple of biscuits (food) in a zip lock bag (stomach) with some water (stomach acid) and then closed the top tightly.
The boys took turns, pretending that their fingers were the muscles inside their stomach, mushing and digesting the food.
Then we left it for a couple of hours and came back to see how it was digesting.
We talked about the path your food travels as it goes through the body and about how long this process usually takes.
We also talked about the types of food you should eat to help this digestive process and about how much water you need to drink each day.
We also looked at some lamb livers that we purchased from Woolworths.
We also used this foam puzzle to learn about the liver, gall bladder and pancreas.
