[|PRISMS] PRISMS is a collection of reviewed phenomena and representations for middle school. Their goal is to help increase the amount of content aligned and pedagogically useful resources available in the National Science Digital Library (NSDL) for middle school teachers and students.

[|The Physics Classroom] Physics Tutorial

__**Enduring Understanding: **__ An object's position can be described by locating the object relative to other objects or a background. The description of an object's motion from one observer's view may be different from that reported from a different observer's view. Model and explain how the description of an object's motion from one observer's view may be different from a different observer's view.

__**Enduring Understanding: **__ Magnetic, electrical,and gravitational forces can act at a distance. Describe the force between two magnets as the distance between them is changed.

[|Exploring Pendulums]The purpose of this Science NetLinkgs lesson is for students to observe the movement of pendulums. By doing this students will begin to understand the relationship between gravitational forces and the mass of objects, the changes in speed and direction of objects, and the distance between objects.

[|Gravity Launch]The purpose of this lesson from Science NetLinks is for students to explore how the earth’s and moon’s gravity affects the path of a rocket launched into space. In the lesson, students will use [|Gravity Launch], an online interactive in which they send a rocket ship to a docking station. They will learn how the force of gravity can pull an object toward the earth and moon, and experiment with different thrust and angle settings to learn how these settings change the motion of the rocket.

[|Exploring Magnetic Fields]The purpose of this Science NetLinks lesson is to reinforce the concept that magnets attract and repel items and exert a magnetic field that can vary in strength. By exploring magnets, students are indirectly introduced to the idea that there are forces that occur on earth which cannot be seen. This idea can then be developed into an understanding that objects, such as the earth or electrically charged objects, can pull on other objects. It is important that students get a sense of electric and magnetic force fields (as well as of gravity) and of some simple relations between magnetic and electric currents.

__**Enduring Understanding: **__ Friction is a force that acts to slow or stop the motion of objects. Demonstrate and explain the frictional force acting on an object with the use of a physical model.

[|How Things Fly]An online exhibition from the National Air and Space Museum.

__**Enduring Understanding: **__ Sinking and floating can be predicted using forces that depend on the relative densities of objects and materials. Predict if an object will sink or float using evidence and reasoning.

<span style="font-family: Georgia,serif; font-size: 110%;">[|Ships 1: Give Me a Tall Ship] This lesson is the first in a three-part series on ships. The overall lesson series is designed to allow students to extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. Ships 1 "Give Me a Tall Ship" is a Science NetLinks activity designed for students to compare the similarities and differences of ancient and modern ships, including size, construction, building materials, and uses.

<span style="font-family: Georgia,serif; font-size: 110%;">[|Ships 2: What floats your boat?] This lesson is the second in a three-part series on ships. In this lesson students aim to design, build, and test the specifications (water displacement and load line) for a model boat. The lesson focuses especially on integrating design principles with inquiry-based experimental skills. In addition the lesson teaches students about load lines and cargo. Using the information from the ship reports they developed in Ships 1, they note that different types of ships can carry different amounts of cargo. They learn that overloading ships has, historically, been a dangerous practice.

<span style="font-family: Georgia,serif; font-size: 110%;">[|Ships 3: Grand Designs and Great Failures]This lesson is the third in a three-part series on ships. In this lesson students aim to students apply what they have learned to develop an explanation of why two real-life ships sank (the British Titanic and the Swedish Vasa). This application of knowledge to real-life situations demonstrates to students that even good designs can fail (the Titanic) and that the solution to one problem often leads to another (the Vasa). It also demonstrates how cultural and contextual conditions can affect both engineering plans and their implementation. In addition students must apply what they have learned in the first two lessons of this series to develop explanations of why two famous historical ships sank on their maiden voyages.
