WHAT TO DO? 1. Bite a piece of bread or cracker and chew it thoroughly. Observe the mouth that helps in
Instructions and Explanations:
This is an experiment activity that you must do to get scientific results. So you just have to follow the instructions and I'm here to simplify it and help you understand it more clearly. I will also be providing the scientific explanations for each step:
Step 1 Bite a piece of bread or cracker and chew it thoroughly: So first, you get a piece of bread or cracker, bite it, and chew until you feel it in a "liquid-ish" texture and that it is broken down into smaller pieces. By biting and chewing the food, the mouth performs the mechanical action of breaking down the food into smaller pieces.
Step 2 Notice the changes in the taste and size of bread/cracker as you chew it: So this is where observations begin. You have to observe and try to determine the changes happening to the food by feeling it inside your mouth. As you chew the food, you may notice the changes happening which is caused by the mechanical action of chewing. Chewing helps mix the food with saliva, which containd enzymes that start breaking down starches into simpler sugars.
Step 3 Swallow it and observe how it is pushed down: Now this is where you swallow the bread/cracker and try to determine how you were able to swallow the food. So once the food was chewed, it will be ready to be swallowed. The tongue helps push the food to the back of the throat which triggers the swallowing reflex.
Let's finalize the experiment, these are the final observations and results:
Observations:
1. The mouth plays a crucial role in chewing and breaking down food into smaller pieces.
2. Chewing thoroughly mixes the food with saliva which makes it softer and easier to swallow.
3. The taste and texture of the bread or cracker changes as it is chewed due to the saliva and breaking down of starches into simpler sugars.
Results:
1. Chewing helps in the mechanical breakdown of food.
2. The action of chewing along with the release of saliva helps initiate the process of chemical digestion.
3. Swallowing pushes the chewed food down the throat and into the esophagus.
I provided the possible and most common answers for this experiment. It's also proven and you can try it for yourself if you want to make sure.
