Pendulums #01

Soft-bound, 56 page book, 20 reproducible task cards, full teaching notes.
A washer swings on a thread, sweeping the face of a cereal box. This box is covered with a grid that measures length and amplitude. It is, in short, a classically simple TOPS learning system. Using a stopwatch and calculator, your students will graph length vs frequency into a beautiful curve; they'll stand this curve on its head by plotting the period, then straighten it back out by squaring the period. This straight line leads directly to a simple pendulum equation with powerful applications. Math teachers, don’t miss this one!

Measuring Length #02

Soft-bound, 48 page book, 16 reproducible task cards, full teaching notes.
Play with nonstandard units of measure, then graduate to the simplicity and ease of decimal-based centimeters. Read and report measurements with plus/minus uncertainty. Estimate the height of tall buildings; reinvent the measuring wheel; improvise meter tapes; design accurate nut-and-bold Vernier calipers.

Graphing #03

Soft-bound, 56 page book, 20 reproducible task cards, full teaching notes.
Measure variables, generate date tables and plot graphs. Interpreted slopes and curves in terms of concrete reality – the stretch in a rubber band or the curve in a bottle. Be amazed by unusual coordinate systems and reflecting graphs.

Balancing #04

Soft-bound, 48 page book, 16 reproducible task cards, full teaching notes.
Can you balance on one foot? (Impossible if the side of your foot is pressed against the wall.) Can you balance a card on a pin? (Easy if you curve the card so its center of gravity is located below the pin point.) Discover the mathematics of balancing with clever mobiles and cantilevers; apply your knowledge to art and engineering. This is a multidisciplinary delight!

Weighing #05

Soft-bound, 56 page book, 20 reproducible task cards, full teaching notes
This book is about science ownership. Students improvise a serviceable and sensitive gram balance that supports all TOPS activities requiring weight measure. The physics of balance equilibrium, centering, sensitivity, restoring forces, reproducibility, trueness, mass vs. weight, all get real on instruments that students build themselves.

Metric Measure #06

Soft-bound, 56 page book, 20 reproducible task cards, full teaching notes.
The perfect sequel to Measuring Length: continue the study of area, volume and mass, and the metric units that measure them. Build metric models that help you visualize the number of stars in the Milky Way. Improvise a sensitive balance to verify that a cubic centimeter holds 1 mL of water and has a mass of 1 gram. By extension, 1000 mL (one liter) has a mass of 1000 grams (one kilogram) or 2.2 pounds. Estimate rice grains by area, volume and mass.

Math Lab #07

Soft-bound, 56 page book, 20 reproducible task cards, full teaching notes.
Great hands-on math: assemble sequences with pennies, create art based on the Fibonacci sequence, fold clever curves, travel a Mobius strip. Go on to crack bar codes, solve puzzles, experience a generalization that turns out to be false. From limits to logarithms, build both math curiosity and math confidence.

Probability #08

Soft-bound, 64 page book, 28 reproducible task cards, full teaching notes.
Involve your students in the mathematics of chance and the science of statistical analysis. Flip coins, spin an alphabet wheel, build a pinball machine based on Pascal’s Triangle, count permutations, tally combinations, plot frequency distributions, calculate odds on a paper-clip spinner, toss a pi without creating a mess!

Floating and Sinking #09

Soft-bound, 64 page book, 24 reproducible task cards, full teaching notes.
Scrutinize how some liquids float upon or sink through others. How will a candle float among these layers? Study the physics by measuring mass, displacing volumes and calculating densities. Build spring balances to measure weight and buoyancy. Discover that immersed bodies are buoyed up with a force equal to the weight of the water they displace. Eureka!

Analysis #10

Soft-bound, 48 page book, 16 reproducible task cards, full teaching notes.
An excellent introduction to chemical analysis, even for students with no chemistry background. Follow simple flowcharts to separate mixtures, observe safe interactions between household substances, compare pH, and more. Simple and elegant.

Solutions #12

Soft-bound, 72 page book, 28 reproducible task cards, full teaching notes.
Begins with corn starch. Mixed cold, it forms a coarse suspension that clears by filtering or settling. When boiled it forms both a cloudy colloidal suspension and a clear true solution. Apply concepts and vocabulary learned here to a series of tasks that clean muddy water: Alum coagulates the clay, chlorination bleaches all traces of food coloring, but only distillation makes it pure. Use common salts to study about crystals, concentration and saturation, rates of dissolving and limits of solubility.

Heat #15

Soft-bound, 56 page book, 20 reproducible task cards, full teaching notes.
Study heat in all its forms, conducting through solids, convecting through fluids, and radiating through space. Experiment with heat absorbers and emitters; cooling curves that reveal the best insulators and conductors; the greenhouse effect in a glass jar. Discover that mass and temperature both matter when computing calories.

Pressure #16

Soft-bound, 80 page book, 32 reproducible task cards, full teaching notes.
Teaching about pressure is usually a matter of locating the right rubber stopper, with the correct number of holes, to fit a flask of the proper diameter, to accommodate glass tubing cut to the desired length. No wonder experiments on pressure usually end up as teacher demonstrations! We eliminate the hassle and safety hazards with rubber tubing, canning jars, rings and lids. Students construct airtight and watertight systems that measure pressure, expand balloons, siphon and pump water and more.

Light #17

Soft-bound, 88 page book, 36 reproducible task cards, full teaching notes.
Scrutinize the particle and wave nature of light: how it reflects, refracts, focuses; how it adds and subtracts color and splits into rainbows. Optical lab equipment usually costs big bucks. Get better results using little more than 2 ordinary hand lenses! Add an extra pair more to model working microscopes and telescopes.

Sound #18

Soft-bound, 56 page book, 20 reproducible task cards, full teaching notes.

Magnetism #20

Soft-bound, 72 page book, 28 reproducible task cards, full teaching notes.
Magnets are fascinating. They provoke our curiosity. Touch a magnet to a straight pin to make another magnet. Hang this pin on a thread to make a compass. Use it to map magnetic fields around a small magnet, or a whole planet. Reverse poles on your pin, chop it into pieces, heat the attracting fragments in a candle flame. These experiments reveal much about the nature of magnetic domains. Create a surprising array of wonderful inventions: electromagnets, solenoids, telegraphs, buzzers, motors, generators and relay switches. What fun (and great science)!

Motion #21

Soft-bound, 88 page book, 36 reproducible task cards, full teaching notes.

Great science, great math, great art, all done with simple materials.

Metric Measuring #35

Soft-bound, 80 page book, 20 reproducible activity sheets, full teaching notes.
Meters, liters and grams are all tied to the same physical reference: a water cube that measures 1 centimeter on each side. We want your students to appreciate this elegant simplicity. So we have developed a parallel measuring system based on sugar cubes. (Purchase cube shapes, not bricks, equivalent to 1 teaspoon.) Your students will use them to develop a concrete understanding of length, area, volume and mass. Ten lessons later they will substitute the idea of water cubes and slip painlessly into metrics. Meters, liters and grams all become old friends as your students make rulers, calibrate measuring cups and improvise gram balances.
