Analyzing Data on Tuskless Elephants
This data-driven activity accompanies the video Selection for Tuskless Elephants. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations.
By watching segments of this video, students will follow the analyses and discoveries of Joyce Poole, a scientist who has studied elephants for many years. Students will then analyze data to investigate the impact of human activity, namely poaching, on elephant populations.
Student Learning Targets
- Analyze quantitative data in order to make predictions based on evidence.
- Use evidence-based predictions to explain how a population changes over time due to human impacts.
- Explain how the selective pressures on a population may impact the frequencies of phenotypes.
- Propose a claim supported by scientific evidence to answer a research question.
- Determine whether scientific results confirm or contradict a hypothesis.
- Provide evidence-based reasoning that uses available data to support a scientific claim.
