Apply today for the HHMI BioInteractive Ambassador Academy! The Academy is a multi-year professional development experience designed to support evidence-based teaching practices. We’re looking for educators with diverse backgrounds and teaching contexts who are committed to centering equity in their classrooms.Laetoli Footprints
Resource Type
Description
This activity explores an image of fossil footprints at Laetoli, which serves as a phenomenon for learning about fossil evidence and human evolution.
Laetoli, a paleontological site in Tanzania, is famous for its fossil footprints of hominins: a taxonomic group that includes humans and their extinct ancestors. The image shows hominin footprints discovered at Laetoli in 2015. Fossil footprints like these can be used to infer biological information about the organisms that made them.
The “Educator Materials” document includes background information and implementation suggestions for using the image as a phenomenon. The “Student Handout” includes the image and background information.
The “Resource Google Folder” link directs to a Google Drive folder of resource documents in the Google Docs format. Not all downloadable documents for the resource may be available in this format. The Google Drive folder is set as “View Only”; to save a copy of a document in this folder to your Google Drive, open that document, then select File → “Make a copy.” These documents can be copied, modified, and distributed online following the Terms of Use listed in the “Details” section below, including crediting BioInteractive.
Student Learning Targets
- Examine images of phenomena, make observations, and ask questions.
- Collaborate with peers on ideas, ask questions that require higher levels of reasoning, and develop deeper understanding of concepts.
- Use fossil evidence to infer biological information about early human ancestors.
