The webcasts with Paleobiologist Advait Jukar aired May 17, 2019, as part of the Smithsonian Science How series. Watch a recording in the player above or by using the link below. After watching the show, please take our survey and tell us how we did!
Did you know that there were many different species of elephants millions of years ago? Go back in time with Paleobiologist Advait Jukar to learn about the different kinds of elephants from the past, see real fossils, and understand how various factors — such as body size, tooth shape, and habitat — each played a role in the evolution of the elephant. Throughout the broadcast, Advait will take questions from your students via text chat and there will be opportunities for students to share what they think using live polls.
Use these resources to support pre/post activities:
3-LS2-1 Construct an argument that some animals form groups that help members survive.
3-LS3-1 Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and variation of these traits exists in a group of similar organisms.
3-LS3-2 Use evidence to support the explanation that traits can be influenced by the environment
3-LS4-1 Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.
4-LS1-1 Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
5-LS2-1 Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
MS-LS4-1 Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth under the assumption that natural laws operate today as in the past.
MS-LS4-2 Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships.
4-ESS1-1 Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time.
MS-ESS1-4 Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth’s 4.6-billion-year-old history.
