Students explore the process of melting or cutting ice. In this scientific observation lesson, students discover that the pressure from two weights will pull a string through an ice cube by melting the ice directly under the line of...

In this efficiency learning exercise, students use the efficiency equation to solve for useful work done by the machine (output). This learning exercise has 10 problems to solve.

Students explore types of motion. In this motion experiment, students observe how objects move. Students work in small groups to discover the laws of motion.

Young scholars create a paper dart airplane and measure its flight pattern. In this flight lesson, students follow the included directions to build their own paper airplane. The young scholars change the aileron configurations to see how...

Pupils visualize the relation between acceleration and velocity in 2 dimensions. They are introduced to Newton's first law,and Newton's second law. Students work on an exploration activity where they condsider an example of a...

In this science worksheet, students look for the words that are related to the theme of the worksheet. They also work on the skills of spelling and word recognition.

Students visualize the relationship between acceleration and velocity as they maneuver a model spaceship in a 2-dimensional applet.

Learners explore the four forces of flight. They investigate the four forces of flight: lift, drag, thrust and weight (gravity). They experiment with flight-testing various objects commonly found around the house and constructing paper...

Third graders observe and discuss examples of friction. They discuss what experimentally increases and decreases friction. They then predict which surface will produce the most friction and verify the prediction.

Students practice problem solving skills and experimental design. They build a vehicle that can traverse "glacial" ice capable of carrying a specific load and glide smoothly, creating as little effort as possible for the skier pulling...

Students perform three activities that each demonstrate one of Newton's Laws of Motion. They use a ramp and toy car to demonstrate inertia, calculate acceleration due to gravity, then use a medicine ball and rolling chair to demonstrate...

Students predict the behavior of coffee in a cup while it is dropped during a demonstration. They relate their observations to the weightless conditions that astronauts experience in space and discuss the concept of free-fall.

Students discuss Newton's 2nd and 3rd laws using the example of a football linebacker and a small child pushing against each other on an ice rink. Students are able to visualize the results of the push and link it to the laws. Discussion...

Students study harmonic motion and its oscillation.  In this simple harmonic motion lesson students demonstrate a series of regular oscillations and explain the theory behind the experiment. 

Fifth graders work cooperatively in groups to assemble and launch a rocket.

Middle schoolers estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Students discover how inclined planes make work easier as they make mathematical predictions and prove their predictions through experiments.

Students describe, compare, and contrast major forces that drive ocean currents. They discuss the general effects of topography on current velocity. They discuss how velocity affects the ability

Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.

Pupils complete several worksheets about machines.  In this machine lesson students complete several handouts that describe the different machines  and how pulleys work. 

Students explain how wind direction affects sail angle. In this physics lesson, students measure the speed of the yacht while varying different factors. They summarize and share their finding to class.

Students use a website to name and compare external body parts of humans and other animals.

Students participate in an online lesson to reinforce the similarities and differences in plants and animals. They classify living things according to observable characteristics.

Students participate in an online lesson showing that gases are formed when liquids evaporate and that when a gas is cooled, it condenses to form a liquid, and gases move and flow more easily than liquids, and how gases differ from solids.
