MASS
Students distinguish between weight and mass. They examine how in oscillations of a mass against an elastic spring--in the absence of gravity, or in horizontal motion--the length of the oscillation period is proportional to the square...

NEWTON'S 3RD LAW
Young scholars examine the formal definition of Newton's 3rd law: "forces always originate in pairs, equal in magnitude and opposite in direction." --The informal, qualitative version: "Each action has an equal and opposite reaction."
Curated OER
MOTION IN A CIRCLE
Young scholars explore uniform circular motion, and the relation of its frequency of N revolutions/sec with the peripheral velocity v and with the rotation period T, and the "centripetal acceleration" of an object.
Curated OER
FRAMES OF REFERENCE: THE BASICS
Students examine the concept of frames of reference in physics: that two frames of reference, each moving with respect to the other with a constant velocity v, observe the same accelerations and therefore Newton's laws are the same in both.
Curated OER
THE MANY COLORS OF SUNLIGHT
Students examine rainbow components, spectral colors, colors perceived by the eye, hot solids, glowing rarefied gas, absorption, that light is a wave, and optics.
Curated OER
WAVES AND PHOTONS
Learners examine the many types of electromagnetic waves, the concept of an EM wave, how James Clerk Maxwell proposed a slight modification of the equations of electricity, Heinrich Hertz and his radio-frequency, wavelengths, and light...
Curated OER
CONVECTION
Students experiment to produce a visual convection current in the classroom and compare it to the images taken of convection cells in the Sun. They analyze the source of the Sun's energy and this type of energy transport.
Curated OER
Magnetic Field Activities
Students explore the idea of magnetic field through investigations of magnetic fields as produced by various common magnetic materials and direct currents. They study the vector nature of fields, the ubiquity of field sources in the...
Curated OER
DEW POINT
Fourth graders investigate conditions causing saturation and measure the dew point of the atmosphere performing simple experiments.
Curated OER
Cloudy Days are for Reading and Writing
Students research weather proverbs and determine the scientific validity of 3 weather proverbs. They write an essay presenting their reasoning. They interview elderly people to graph the most frequently heard proverbs and theorize...
Curated OER
Creating Station Models
Learners review weather conditions at various cities and create station models on a weather map.
Curated OER
Is There Water on Mars?
Young scholars decide whether or not there is or has even been water on Mars. They analyze temperature and pressure data from the Pathfinder mission to Mars, and then they analyze images of Mars, interpreting the landforms they see and...
Curated OER
Modeling Hot and Cold Planets
Students, in teams, design and construct models of two planets, one hot and the other cold, using a variety of materials. They attempt to create the models out of substances that will actually show the greatest temperature differences...
Curated OER
Comparing Amount of Rainfall in Different Geographical Areas
Third graders create rain gauges and take them home. Individually, they record the rainfall amounts at all of their homes over a 2-week period and then bring the data back to class so they can compare the different amounts of rainfall...
Curated OER
More Rocket Science
Young scholars observe two rocket science experiments, and create a graph to demonstrate the results. They draw a picture and write an explanation of the results of the experiments.
Curated OER
Countdown Begins
Young scholars explore the countdown sequence for a rocket launch. They watch a video of a rocket launch, discuss the significance of the countdown sequence, and place ten paper rockets in the proper sequence.
Curated OER
Getting in Shape Again
Students create rocket shapes out of pattern blocks. They draw a picture of a rocket, build a pattern block rocket following simple directions, and complete a graph of the shapes used.
Curated OER
Snow Goggles And Limiting Sunlight
Learners build snow goggles similar to those used by the Inuit people. They create their version of the goggles to improve upon existing designs. Pupils compare the process used to invent snow goggles with that employed by the MESSENGER...
Curated OER
Our Own City
Students will construct their own functioning city. Each day students will add to the city requiring adjustments and planning. They solve problems caused by increase in human settlement such as stacking houses creating apartments so that...
Curated OER
Solar Eclipse
In this solar eclipse worksheet, students solve seven problems about solar eclipses after making a model following five steps. They determine the different orbits for satellites, they determine the lengths of Earth's shadow and they find...
Curated OER
Lunar Cratering-Probability and Odds
In this lunar cratering worksheet, young scholars use probability to determine the outcome of coin flipping. They use this to represent the probability that asteroids will strike the moon in already cratered areas.
Curated OER
Stream Table
Students build and erode a hillside. In this earth science lesson plan, students build a five inch hillside in a paint pan using sand, soil, and pebbles. They pour water over the hillside to monitor the erosion and how it is affected by...
Curated OER
Locating Echo
Students read the book The Adventure of Echo the Bat. For this animal science lesson, students read the book and create a chart labeled "Land Feature," "Habitat," and "Food." Students fill in the table according to where the character...
Curated OER
Create a Cloud in a Bottle
Students look at how clouds form. In this cloud lesson plan, students make a cloud using water, 2 liter bottles and a match. They watch how the pressure and temperature changes the atmosphere in the bottle to create a cloud.
