Students investigate different types of simple machines. They identify simple machines as part of daily life. They build a simple machine.
Ring Around the Rosie
Students examine the concept of angular momentum and its correlation to mass, velocity, and radius. They listen to a teacher-led lecture, conduct an experiment with rotational inertia, angular momentum, and rotation speed by making variations of spinners and comparing the different spins they produce, and answer discussion questions.
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.
All About Electric Motors
Students study the basic principles of electric motors and explore everyday uses. They build a working model of an electric motor for classroom use, using an inexpensive kit. Then, they work as an "engineering" team to determine the changes they would need to make to the motor to adapt it to power a hairdryer.
How Gear Systems Work: A Research Project
Fourth graders apply information regarding simple machines along with the math concept "ratios." The teacher introduces the concept that technology is the application of scientific knowledge and mathematics concepts to solve a problem. This is repeated with the wheel and axle.
Solar Kit Lesson #13 Solarize a Toy
Students work in teams they select a low-power toy, game, or electrical deive to "solarize," or convert to solar power. They determine the operating voltage of their chosen device and design a solar array to provide this level of voltage. Pupils determine a series of conditions under which they test their toy's performance and, if needed, adjust the size of their solar array to provide more current.
Solar Kit Lesson #13 - Solarize a Toy
Physical science or technology classes will be invigorated by this challenge: to convert a toy, game, or other device to run on solar power. In doing so, they will design the appropriate solar arrays. This is an A+ lesson, complete with background information, teaching notes, and student instructions.
Rockets Away with Newton's Laws of Motion
Eighth graders comprehend Newton's Laws of Motion and to use the scientific method in rocketry sub-unit. They work through the scientific method. Students illustrate how science and Newton's Laws can be used in everyday situations and movement.
Deflection of Balsa Wood Bridges
Students Experimentally determine the smallest deflection to load ratio (Â¿Â¿y/P) for a given length of four different beam designs of balsa wood. They analyze the results for different beam designs and relate the equation that describes how deflection varies with the geometry of the beam.
Dolls in Tunics & Teddies in Togas
Young scholars identify the basic components of male and female Roman costume, both for children and adults and also, the major social ranks of Imperial Rome and the dress reserved for each gender and rank. They also identify some of the activities considered appropriate for each gender and rank and the appropriate Latin names for clothing and accessories.
Technology Tradeoffs: Why Should I Care?
Power generation and energy usage are the focus of a lesson on technology tradeoffs. Class members consider the positive and negative effects of such energy sources as diesel fuel and gasoline, and after considering the tradeoffs, take a stance on which they would choose and why. Attachments, rubrics, extensions and a bibliography are included.
Step-up, Step-down, and Isolation Transformers
In this circuits and transformers worksheet, students answer 34 questions about loads, voltage, currents and waves associated with circuits.
In this online interactive reading comprehension learning exercise, students respond to 25 multiple choice questions about Beowulf. Students may submit their answers to be scored.
Review of Oscillations
In this oscillations instructional activity, students complete 50 multiple choice questions on forces, motion, periodic motion and simple harmonic motion.
Physics (Rot Mo-2):Balancing Nail Act
Tenth graders examine the concept of equilibrium, balance, center of gravity and torque by conducting an experiment. In this balance lesson, 10th graders work in groups to balance six nails on the head of the nail driven into a board. Students must figure out a solution to how to balance the six nails without using glue, fasteners, rubber bands, or strings.
The Founder of Electromagnetism
Students identify and study the founder of electromagnetism. In this magnetism lesson students complete several experiments including building a galvanometer.
Students study the Venus Flytrap including its habitat and how it eats. In this ecology lesson students complete several experiments using a Venus Flytrap to see how it reacts to various conditions.
Activity: Slinkies and Magnetic Fields
Your advanced physics class will appreciate this lesson in which they use magnetic field sensors to determine the relationship between the number of turns per meter of a solenoid and the magnetic field produced. The materials for this lesson are costly and ample time is required to prepare for the lesson. It is explained in detail, however, and outstanding resources are included. This is ideal for your stronger science scholars.
Can you feel the weight of the world? After viewing this PowerPoint, your physics class will. They learn that because of the gravitational pull of the sun, Earth does not go flying off into space. They also learn how to use the universal law of gravitation to calculate Earth's mass and the inverse-square law to relate intensity and distance. This is a descriptive demonstration of these physics concepts for your high schoolers.
Students create their own model of a nail clipper. They practice using engineering design and model building. They also identify different kinds of small levers.
