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 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 explore the role of gravity in the motion of falling objects.
This lesson is based on the highly engaging book Feathers: The Evolution of a Natural Miracle by Thor Hanson. Alternate texts and strategies for sharing are provided in case there are not enough book resources for all students to have an individual copy. As they read, students will take notes and then participate in an interactive "grab bag book review" where they will take objects from a bag, one at a time, to act as prompts for re-telling big ideas from the book and lesson.
Students examine the interdependence of global trade in the context of the economic and social aspects of fisheries and aquaculture.
Flowering plants keep the world cooler and wetter than it would be otherwise.
In this lesson students will learn about the motion of the pendulum and how it proves the earth is rotating. There is a teacher's answer key to go along with the student activity sheet.
Students explore a bay ecosystem and how the different organisms of the ecosystem compete with one another for resources.
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 dinosaur fosisls as well as understand that some fossil facts are made based on comparisons with living organisms.
Students read the online booklet "Fossils, Rocks, and Time" which provides an introduction to the study of earth's history and the role fossils play in helping us understand this history.
In this lesson, students demonstrate that it is the tilt of Earth's axis that causes the seasons.
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.
This lesson introduces students to the genetic information stored in DNA within the human cell nucleus.
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 learn about the problems of waste disposal and how recycling can help to reduce the amount of waste we create.
Students will understand the pattern of genetic variation among humans and how variation has been introduced into our species over time. As a culminating activity, students will pick a trait variation to research and report.
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.
To identify how germs are spread, the diseases they can cause, and how hand washing can help prevent the spread of germs.
