Reflection….
• Prompt: List one thing you learned, one thing you found interesting, and one thing you would like to learn more about/investigate further.
• Bodily Fluids• pH /Determining unknown acidity and
alkalinity.• Blood Typing (A, B, AB, O)

Blood Typing Clarification
Agglutination
• A process that occurs within blood cells when the incorrect blood type is given to a patient.
Simply referred to as clumping

Who can give/receive blood?

Is it possible….
• What is the meaning of the term ?
• Bioluminescence is the production and emission of light by a living organism.
• What organisms come to mind when you hear this term?
How does it occur?
• One way is by the chemical reaction pigment luciferin. An enzyme known as luciferase oxidizes the pigment causing the glow effect. Show students the chemical reaction.

• Another way is through genetic engineering with a protein known as GFP, Green Fluorescent Protein.
GFP?
• Green Fluorescent Protein:-It was first isolated from a jellyfish Aequorea victoria.-It fluoresces when exposed to ultraviolet light
