Glow Sticks Part I- Water Treatment (room, hot, cold)

• Students learned the first "glow in the dark" gene for the chemical luciferin was isolated from jellyfish. The

• Jellyfish gene for green fluorescent protein (GFP), is placed in organisms and one day scientist hope to light up streets with fluorescent trees. Students experimented with glow sticks to determine if temperature affects the brightness. It is reported that fireflies glow brighter on warm summer nights.

Aaron and Gus use a black background for greater contrast. Only one glow stick was broken prior to being submerged into various water temperatures.

Phylicia checks the temperature of the three cups.

Data from Jordan and Phylicia

Emma test the water temperature for glow sticks Curiosity investigation.

Color coordinated tops help the team add a

touch of personalization to their tasks at

hand.

• Riddi, Emma and Brianna breaks their glow sticks simultaneously.

Data from Brianna, Emma and Riddi

Riddi, Emma and Brianna check the temperatures of water and observe which temperature causes sticks to glow brighter. Its “reasoning time” based on observations.

Phylicia and Jordan observe another group as their sticks finally light. up

Qualitative data is taken using a white background VS a black background

Gus measures the water temperature as Aaron reads over their experimental design.

Aaron and Gus extend their observation period to determine which water temperature promotes a brighter glow.
