In this activity, students will "dig" for paper fossils and make observations of various fossils to determine characteristics of chimpanzees and humans. Students will then use their new knowledge to dig up and analyze a new fossil discovery that must be presented, with evidence, to the scientific community (class) during and oral presentation.

Dolphins and other marine mammals have pretty big brains compared to the size of their bodies. That?s one indication of high intelligence, and anyone who has seen them perform at an aquarium or zoo can attest to that fact. This Science Update introduces us to one scientist who?s trying to find out how dolphins got so brainy.

In this lesson, students annotate a photograph of a local study site and then develop a more abstract diagram of the site that highlights the flow of energy and matter among the four components of the Earth system. The investigation concludes with students sharing their diagrams and creating a single class diagram to represent their study site.

This lesson is about the flow of energy in ecosystems. The setting is Plimoth Plantation, a living history museum in Plymouth, Massachusetts, USA, where students will learn about the first Thanksgiving meal in America, celebrated in 1621 by early American settlers and Wampanoag Indians. By examining this meal and comparing it to a modern day Thanksgiving celebration, students will be able to explore the way in which food energy moves and is transformed in an ecosystem.

In this field investigation, students will develop a question regarding an environmental change and its effect on insect visitation rates to a plant community. After writing a question, students will develop multiple hypotheses and design an investigation to test their hypothesis. After their investigations, a presentation will be given to their classmates discussing their results.
