The Bloody Red Cabbage Juice- pH

Design Your Own Lab (DYOL)

Students learned about body fluids and pH as one of the greatest factors that affect body fluids.

Phylicia and Jordan designed a lab to determine which unknown liquid was an acid or a base. The team collaborates before recording data into the data table.

• Emma has a great idea.. Record both quantitative data and qualitative data.

• Aaron and August (Gus) predict which liquids are involved in the investigation.

Aaron and Gus design their glow stick lab. Do fireflies really glow brighter on warm nights? Which temperature of water causes

glowsticks to glow brighter? Room, cold or warm?

Aaron swirls the red cabbage juice indicator to determine pH of an unknown liquid.
