Students will conduct a number of investigations involving density and buoyancy to understand the forces applied to objects and the resulting interactions among them.
Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

Pascal's Principle states that when a force is applied to a confined liquid, an increase in pressure is transmitted equally to all parts of the fluid.
In this lesson designed to enhance literacy skills, students learn how the forces of gravity and air resistance affect the motion of falling objects.
Lesson for kindergarten SEEd strand 3.1Standard K.3.1Plan and conduct an investigation to compare the effects of different strengths or different directions of forces on the motion of an object. Emphasize forces as a push and pull on an object. Image source:Created by Laura Anderl through https://www.bitmoji.com
This article provides science content knowledge about forces that shape the Earth's surface: erosion by wind, water, and ice, volcanoes, earthquakes, and plate tectonics and how these forces affect Earth's polar regions.
This media-rich essay from NOVA Online describes the challenges of forecasting volcanic eruptions and includes information about specific cases.
In this lesson plan, educators will learn to teach students how to swing forehand and backhand. Educators will also review how they introduce, describe, and close the lesson.
Information from the Library of Congress about the impact of stances on foreign policy and peace on presidential elections and campaigns.
This video segment from NOVA: "The Killer's Trail" investigates the potential for DNA evidence to solve murder cases, even those from the distant past.
A site that has interesting information on forensics and interactive activities for kids to play. The student will learn investigative techniques that will enable them to better understand the science of forensics. The use will explore new technology related to anthropology and forensics.
Your team has been approached by the Forest Service to help allocate resources to fight wildfires. In particular, the Forest Service is concerned about wildfires in a wilderness area consisting of small trees and brush in a park shaped like a square with dimensions 80 km on a side. Several years ago, the Forest Service constructed a network of north-south and east-west firebreaks that form a rectangular grid across the interior of the entire wilderness area. The firebreaks were built at 5 km intervals.
Wildfires are most likely to occur during the dry season, which extends from July through September in this particular region. During this season, there is a prevailing westerly wind throughout the day. There are frequent lightning bursts that cause wildfires.
Several types of forests are highlighted on the map, including northern coniferous forests (located between 50-60 degrees latitude), temperate forests (located below 50 degrees latitude), and tropical forests (located near the equator).
The subtropical forest is located in southern Florida, mostly in the Everglades.
Temperate deciduous forests cover most of eastern North America below 50 degrees north latitude.
Discover the work of Cornelia Adèle Fassett, one of the first female portrait artists of the 19th century to portray American presidents, politicians, and Supreme Court Justices.
Formative Assessment is a planned, ongoing process used by all students and teachers during learning and teaching to elicit and use evidence of student learning to improve student understanding of intended disciplinary learning outcomes and support students to become self-directed learners.
