Do Crayfish Change Color If Their Environment Changes? A Guided Inquiry Lab for 7th grade Life Science
Background: There is anecdotal evidence from bass fisherman that crayfish are able to change color depending on their surroundings. A (cursory) literature review of this phenomenon showed that no formal research has been done in this area. Students had an additional informal lesson about research funding (or lack thereof) because of this finding.
Students designed and conducted a controlled experiment to see the effect of changing environment color on crayfish color.
ADI was used to quantify a color change.
