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.

Students explore the relationship between gravitational forces and the mass of objects, the changes in speed and direction of objects, and the distance between objects.
Students will build on their existing knowledge of the solar system as …
Students will build on their existing knowledge of the solar system as they research one of the planets in order to determine whether a manned mission to that planet would be feasible. Students will collect information about the geology, composition, and orbit of their assigned planet. They will then work collaboratively to create a proposal for or against planning a trip to the planet to be presented to the rest of the class.
Students discover what can be learned from fossils and in doing so, …
Students discover what can be learned from fossils and in doing so, realize the difference between fact and theory. They will also gain understanding of how fossils are formed.
Students recognize the kind of information that can be accumulated by studying …
Students recognize the kind of information that can be accumulated by studying dinosaur fosisls as well as understand that some fossil facts are made based on comparisons with living organisms.

This lesson is the first of a two-part series focused on how scientists perform their work. These lessons make use of a book called The Frog Scientist, by Pamela S. Turner. Students will read the book and view and analyze supplemental resource materials to better understand how scientists are using the scientific method to study human environmental impact.

This lesson is the first of a two-part series focused on how scientists perform their work. These lessons make use of a book called The Frog Scientist, by Pamela S. Turner. Students perform a field investigation of their schoolyard"™s ecosystem, which includes living (biotic) and non-living (abiotic) factors. They will brainstorm questions to ask about their outside school grounds, make and record observations, interpret their results, draw conclusions, make predictions, and report their work in the form of a science poster.
Students will model carbon dating and how it can be used to …
Students will model carbon dating and how it can be used to determine the age of fossils and other materials. They will use a simple graph to extrapolate data to its starting point.
Students will come to understand that in sexually reproducing organisms, such as …
Students will come to understand that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. Students will examine a fictional pedigree and determine which gene is responsible for a given trait. The genetic information for individuals is depicted as a jigsaw puzzle.
Students explore the geological history of Mercury and the other terrestrial planets, …
Students explore the geological history of Mercury and the other terrestrial planets, Venus, Earth, and Mars. The development of the lesson revolves around GeoHunter, an interactive for planetary geology. They will also learn about MESSENGER, the spacecraft mission to Mercury.
