This is lesson to begin learners' thinking about magnetic influence. Learners will watch a classroom demonstration about the effect of magnets on iron filings and then complete a journal assignment to record their reactions and thoughts. This is the first activity in the Mapping Magnetic Influence educators guide.

Students use their understanding of projectile physics and fluid dynamics to find the water pressure in water guns. By measuring the range of the water jets, they are able to calculate the theoretical pressure. Students create graphs to analyze how the predicted pressure relates to the number of times they pump the water gun before shooting.

This fact card discusses the shape of space and how light is affected by the amount of dark matter and energy in the universe. MAP's microwave detection gives us enormous insight into the creation of this matter and energy. Note: this resource was published prior to the mission name change from MAP to WMAP (Wilkinson Microwave Anisotropy Probe) to honor Dr. Wilkinson.

Today we’re looking at silicon, and how introducing small amounts of other elements allow silicon layers to conduct currents, turning them into semiconductors. We’ll explore how putting two different types – N and P semiconductors – together gives us electrical components like diodes, transistors, and solar cells.

Student teams make polymers using ordinary household supplies (glue, borax, water). They experiment with the semi-solid material when warm and cold to see and feel its elastic and viscous properties. Students will begin to understand how the electrical forces between particles change as temperature or the force applied to the substance changes. Is it a solid, a liquid, or something in between? How might it be used?

In this activity, students play the game Simon Says to make the amplitudes and wavelengths defined by the teacher. First they play alone, and then they play with a partner using a piece of rope.

Students build and use a very basic Coulter electric sensing zone particle counter to count an unknown number of particles in a sample of "paint" to determine if enough particles per ml of "paint" exist to meet a quality standard. In a lab experiment, student teams each build an apparatus and circuit, set up data acquisition equipment, make a salt-soap solution, test liquid flow in the apparatus, take data, and make graphs to count particles.

Through a five-lesson series with five activities, students are introduced to six simple machines inclined plane, wedge, screw, lever, pulley, wheel-and-axle as well as compound machines, which are combinations of two or more simple machines. Once students understand about work (work = force x distance), they become familiar with the machines' mechanical advantages, and see how they make work easier. Through an introduction to compound machines, students begin to think critically about machine inventions and their pervasive roles in our lives. After learning about Rube Goldberg contraptions absurd inventions that complete simple tasks in complicated ways they evaluate the importance and usefulness of the many machines around them. Through the hands-on activities, students draw designs for contraptions that could move a circus elephant into a rail car, create a construction site ramp design by measuring different inclined planes and calculating the ideal vs. actual mechanical advantage of each, compare the theoretical and actual mechanical advantages of different pulley systems conceived to save a whale, build and test grape catapults made with popsicle sticks and rubber bands, and follow the steps of the engineering design process to design and build Rube Goldberg machines.

Students apply the mechanical advantages and problem-solving capabilities of six types of simple machines (wedge, wheel and axle, lever, inclined plane, screw, pulley) as they discuss modern structures in the spirit of the engineers and builders of the great pyramids. While learning the steps of the engineering design process, students practice teamwork, creativity and problem solving.

This is a calculus-based physics textbook meant for the type of freshman survey course taken by engineering and physical science majors, or for AP Physics C. It uses a nontraditional order of topics, with energy coming before force. For instructors who prefer the traditional sequence, there is a drop-in replacement for ch. 0-4, Mechanics, that covers force before energy. My text for the type of course usually taken by biology majors is Light and Matter.
In this activity, students are challenged to design a contraption using simple …
In this activity, students are challenged to design a contraption using simple machines to move a circus elephant into a rail car. After students consider their audience and constraints, they work in groups to brainstorm ideas and select one concept to communicate to the class.

In this hands-on activity, students learn about the different realms of the Universe and explore their sizes and relative scales. They will be guided through a process that uncovers the immense sizes of the Sun, Solar System, Solar Neighborhood, Milky Way, Local Group, Supercluster, and the observable Universe. The full version of this activity involves students doing simple math computations, however it can also be done without the math. There are some inexpensive materials involved, as well as a powerpoint presentation. It is intended for grades 8-12, but can be adapted down for lower grade levels.

This is an activity about the size of the Sun. Learners will construct a pinhole camera and, using the projected image of the Sun, calculate its diameter. After calculating the diameter of the Sun, learners will create a classroom sized scale model of the Sun and Earth. This activity requires use of a sunny outdoor location to be able to use the pinhole cameras.

Through this unit, written for an honors anatomy and physiology class, students become familiar with the human skeletal system and answer the Challenge Question: When you get home from school, your mother grabs you, and you race to the hospital. Your grandmother fell and was rushed to the emergency room. The doctor tells your family your grandmother has a fractured hip, and she is referring her to an orthopedic specialist. The orthopedic doctor decides to perform a DEXA scan. The result show her BMD is -3.3. What would be a probable diagnosis to her condition? What are some possible causes of her condition? Should her daughter and granddaughter be worried about this condition, and if so, what are measures they could take to prevent this from happening to them?

This is an activity about the electromagnetic spectrum and how the different wavelengths of light are used to capture the most complete picture of objects in space. Learners will view images of our galaxy in multiple wavelengths to compare and analyze what is seen. This activity requires a computer with Internet access, and is Astronomy Activity 3 in a larger resource entitled Space Update.

What if you were on a high floor of a skyscraper and the building started swaying? Today we’ll explore statics and dynamics, and what they mean for the structures we design. We look at the idea of static equilibrium, forces, and torques, and how free body diagrams can help us make sense of it all.

In this activity students use their Log Tapes as a reference for ordered pairs, and graph positive numbers as a function of their base-10 logarithms. They extend each plotted point to the vertical axis, thereby generating a logarithmic scale that cuts and folds into an improvised slide rule.åÊThis is activity E1 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure,compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.åÊ
