The Fossils MEL

MEL Activities

There are two forms of this MEL Fossils Activity....a pre-constructed (pcMEL) and a build-a-MEL (baMEL). The pcMEL limits student choices, which may be good for the first time the activity is introduced to a class or if you are working at earlier grade levels. The baMEL allows more choices, which may be good for students who have used the MEL before or are at an advanced grade level. Below the activity links are additional teaching resources that will help students to make claims and justify the connections between fossil evidence of past climates and current scientific models that present Earth's climate as dynamic and ever-changing.

Overview

This article provides an provides an introduction to the Fossils build-a-MEL (baMEL). It is useful even if you are using the Fossils pcMEL with your students. The primary difference between the pcMEL and the baMEL is that with the pcMEL students are given two models and four lines of evidence in a preconstructed diagram where as with the baMEL students choose two models from three and select four lines of evidence from eight to create their own MEL diagram.

Next Generation Science Standards Performance Expectations

HS-LS4-6: Biological Evolution: Unity and Diversity

• Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.

HS-ESS2-7: Earth's Systems

• Construct an argument based on evidence about the simultaneous coevolution of Earth's systems and life on Earth.

Lateral Reading (LR) Resources

What does it mean for a source to be credible? Why should we investigate whether a source is credible before we read it? How do we decide whether online sources are credible? Use lateral reading to find out.

Use lateral reading to evaluate the credibility of three sources related to fossils.

These LR sources connect to Evidence #3: The Svalbard forest in Arctic Norway is filled with fossils of tropical trees, called Lycopsid. These trees lived hundreds of millions of years ago.

Use the LR Guiding Questions to evaluate the credibility of each source.

  Popular Science (also known as PopSci) is a U.S. popular science website that covers science and technology topics geared toward a broad, general audience.

  The Daily Mail is a British tabloid. It is widely read in Britain, but according to Wikipedia, it has "been criticized for its unreliability, its printing of sensationalist and inaccurate scare stories about science and medical research, and for instances of plagiarism and copyright infringement."

This Plausibility Ranking Task (PRT), which may be completed prior to using any MELs, helps students to understand the role of evidence in supporting or refuting models.

Digital Resources

This classroom resource, Prehistoric Climate Change and Why it Matters Today (Acrobat (PDF) 3.6MB Sep24 25), from the Smithsonian Institute includes background information and an activity that engages students in leaf margin analysis. There are also web pages with videos and interactive labs. Prehistoric Climate Change learning lab.

The geology, fossils, and human stories of Florissant Fossil Beds National Monument in Colorado are part of a common geologic heritage. Shadows of the Past, a video from the National Park service, shows how the fossil beds hold clues of unexpected environments and life that existed there during the late Eocene.

In Conservation paleobiology: Eyeing the past to restore today's ecosystems researchers use historic remnants like antlers, shells, teeth and pollen to learn how natural communities once worked. The clues serve as guides for restoration.

In the Smithsonian's National Museum of Natural History paleobiologists study fossil plants. What Fossil Plants Reveal About Climate Change describes how fossil plants help researchers to reconstruct Earth's past climate and inform research on modern climate change.

Every year the National Park Service celebrates National Fossil Day with fossil-related events and activities across the country in parks, classrooms, and online. Check out how you and your students can get involved.

The Digital Atlas of Ancient Life virtual collection hosts interactive 3D models of fossil specimens from the collections of the Paleontological Research Institution. The digital specimens can be rotated and annotated. All of the models have Creative Commons 0 (CC0) licensing and may be freely viewed, downloaded, 3D printed, and otherwise used as desired for noncommercial use.
