activity 1Visit the website below to see how your body digests different foods. Be able to explain it to a friend.
Activity 2Make a Model of the Digestive System
Follow the directions on page 90 of the textbook to make the model. Take pictures or a video and explain your model to your audience. |
activity 3Once Upon a Family Blog
Mix it Up & Squeeze
Mechanical digestion is the physical breakdown of food by teeth or muscles to make chemical digestion more effective. Materials Needed: esophagus (paper tube) stomach (large zip top freezer bag); chemicals and enzymes (food colouring); saliva (3 spoonfuls of water) food (banana and crackers). 1. Mechnically digest the food in the mouth before it reaches the stomach (crush the crackers and slice up the banana) 2. Add the food, saliva,enzymes and chemicals to the stomach through the esophagus. 3. The food in the stomach is squeezed and mixed before passing into the small intestine. Document each step with photographs and add it to our class blog. Bon appetit! |
activity 4Nelson Science Probe 5
Make a Model of Peristalsis
Peristalsis is the action of muscles that moves food through your digestive system. Follow the steps in your duotang to make a model and then use the video camera to teach a friend. Make sure you answer the questions. |
