Investigation Plan – (Why We Chew Food)
Name:………………………………………… Date:………. ……….
Aim: The aim of this practical is to find out whether or not chewing our food effects how fast the acid in our stomachs breaks down the food.
Prediction (what you think will happen)
I think the broken tablet will dissolve faster then the whole tablet
Hypothesis ( like a prediction but with a reason why )
I think this will happen, because the broken tablet has more parts of it that will be touched by the acid. This means it will dissolve faster
The variable we will change is ( Independent Variable ) The size of the tablet piece(s) we place into the acid
The variable that we will measure is ( Dependent Variable) How long it takes the tablets to dissolve
The variables that I will keep the same are ( Control
)…………
Type of tablet……size of tablet piece(s)…..temperature of acid….type of acid…strength of acid…..size and shape of beaker
The equipment I am using:
1.
Beaker
2.
Dissolvable table
3.
Mortar and Pestle
4.
Hydrochloric Acid
5.
Beaker
6.
Stope Watch
