Students complete a chromatography experiment, In this chromatography lesson, students complete an experiment similar to one that was to be carried out on the Challenger that exploded. They examine ink spots as the wick on filter paper....

Students examine the topics of ocean waves, currents, and tides. They locate and label ocean currents on a world map, conduct experiments, analyze key vocabulary, view demonstrations and record the data, and complete handouts.

Students explore questions which cannot be handled with simple pendulums, and examine both the usefulness and the limitations of approximations in science. A Java applet created from a Stella model is included.

Students conduct experiments to determine if length, mass, or starting angle has any effect on the rate of a pendulum's swing. They also conduct an experiment online to determine if gravitational force plays a role in the swing. Groups...

Third graders examine the concept of work as the movement of an object through a distance. They define gravity and determine what type of work is caused by gravity. They measure how far an object is moved by a force. They make a...

Young scholars explain that planets actually orbit the center of gravity of the solar system, and that distant planets may be detected by motions of their central star around the centers of gravity of their planetary systems.

Students investigate how body design affects balance. They make simple models of dinosaur bodies using straws and marshmallows. Before making their models, they discuss the effects of gravity and the importance of balance in body shape.

Ninth graders compare the nature of forces of gravity, lift, thrust, and drag. They select proper materials for making a kite and attach a proper tail. Students interpret and summarize the observations made during the flight of the kites.

Pupils perform experiment in which they model convection as it occurs in our Sun. They also explain that convection acts where the effect of gravity and heat are present (low density fluids can rise and cool, and high density fluids can...

Ninth graders use model-building to help comprehend the forces and phenomena at work in the world around them. They describe gravity as a universal force that pulls everything toward the center of the earth. Students distinguish between...

Young scholars 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...

Students 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...

Sixth graders discuss the effect of gravity on objects. In groups, they participate in different activities in which they observe the effect of motion on objects and how energy is transferred between objects. To end the lesson, they...

Tenth graders experiment with detection techniques for black holes by modeling the rotation of galaxies with larger and larger masses in the center. They discover while some events cannot be directly observed they may be observable in...

Is it a bird? Is it a plane? It's super student! Physical science stars can fly during a unit on light as they see the reflection of one leg in a mirror, behind which the other holds them up. 

Young scholars use this introductory lab using a tennis racquet, however it is very difficult to study because of the strings and the racquet stretch so little and so quickly during a match that students were unable to make simple...

Force equals mass times acceleration. Physics whizzes apply this formula to six different diagrams, solving eight acceleration problems in all. This is a practical assignment, perfect for homework when practicing Newton's second law of...

Students explore paper rockets, learn about the Apollo Program and Apollo spin-offs, and use simple office supplies to design and create a new useful product. This amazing plan is incredibly well written and leads students through a...

Meteorology learners explore the weight of air, layers of the atmosphere, and air pressure action through a series of discussions, demonstrations, and hands-on group activities. Enough discussion prompts, background information, student...

A helpful worksheet describes an interesting demonstration on the surface tension of water. Learners guess how many drops of water the heads side of a penny will hold. This resource does a great job of describing just how a penny can...

Electricity is the focus of this college-level midterm exam. It requres physics learners to answer multiple choice and short answer questions in addition to evaluating several diagrams and graphs. This is appropriate for most high school...

You've got the power! With this physics midterm, you have the power to assess learners' grasp of electricity concepts. The exam is neatly formatted and provides a variety of question types: true or false, multiple choice, and problem...

The physics department at The University of Hawaii has designed midterm exams for their college physics courses. This version deals with electricity concepts. It requires learners to calculate conversions, capacitance, and potential...
