Aim: I want to find out how red cabbage can tell if a liquid is an acid or a base.
Research:
Method:
Equipment:
Red Cabbage
Large Beaker
Acid (Hydrochloric Acid)
Base (Sodium Hydroxide)
Eyedropper
Test Tube (6)
Warm Water
Instructions:
Wash your hands.
Get your equipment.
Put warm water in the beaker.
Rip red cabbage into very small pieces.
put the red cabbage into the beaker.

I didn't get any videos because I had to leave early so I will add an internet photo.
Discussion:
What is an acid and a base?
An acid is a contributing product containing hydrogen ions. Now the solution contains more hydrogen ions than hydroxide ions. That form of solution is acidic. A foundation is a material capable of consuming hydrogen ions. As a base is dissolved in water the equilibrium between hydrogen ions and hydroxide ions changes in the opposite direction.
What do chemical indicators do?
chemical indicator, any substance that gives a visible sign, usually by a color change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. The common application of indicators is the detection of endpoints of titrations.

How do you taste food:
The taste buds pick up clues about how food tastes and send messages about it to your brain along special wires called nerves. To taste something properly, you need to chew food into small pieces and have a lot of drool, or saliva. This helps the flavor molecules (also known as “tastants”) reach your taste buds.
What are the different taste buds of our tongue: Taste buds contain the taste receptor cells, which are also known as gustatory cells. The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, cheek, and epiglottis.
Does smell affect your taste:
Our sense of smell is responsible for about 80% of what we taste. Without our sense of smell, our sense of taste is limited to only five distinct sensations: sweet, salty, sour, bitter, and the newly discovered “umami” or savory sensation. All other flavors that we experience come from the smell.
