Curated OER
Activity #6 'Nothing' Matters: A Demonstration
Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.
Curated OER
Determining Liquid Densities
Pupils practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table. Pupils...

Graphical Determination of Density
Learners determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.
Curated OER
In-Line Inertia
Students practice calculating the moment of inertia when discussing a skater and the position in which it is best to spin. After class discussion, students practice calculating inertia on their own.
Curated OER
Newton's Earthquake
Students discuss Newton's 2nd and 3rd laws using the example of a football linebacker and a small child pushing against each other on an ice rink. Students are able to visualize the results of the push and link it to the laws. Discussion...
Curated OER
CO2 and Mass
Students determine if carbon dioxide has mass. In groups, they use a standard set of materials to test the carbon dioxide. They answer questions on their lab sheet and discuss them as a class.
Curated OER
Rocks, Their Mass and Volume
Students measure volume using water displacement and mass using a balance. Once they have calculated these two values they will then calculate density while at the same time working on long division. After the activity and explanation of...
Curated OER
What Goes Up Must Come Down!
Pupils hypothesize about the nature of falling objects, design an experimental test to answer the question using everyday objects, analyze data to form conclusions, and infer that mass does not affect the speed of falling objects. This...
Curated OER
Estimating the Live Mass of Dinosaurs
Students estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. Students compare the...
Curated OER
Causal Patterns in Density Phenomena
Students define density as a relationship. Through experimentation, they explore the association between the mass and volume of pure substances. Students create a data plot and analyze the patterns between mass and volume. Students...
Curated OER
Lesson-Mass and Weight
Student identify the three stationary positions, on the Earth, on the Moon, and in a house floating atop the cloud layers of Jupiter. They also identify the three orbiting positions, orbiting the Earth, orbiting the Moon, and orbiting...
Curated OER
Quantum Physics
Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...
Curated OER
Conservation of Mass
Sixth graders discover the difference between weight and mass. In an experiment, they examine the Law of Conservation of Mass in action and discuss if a physical change causes a change in mass. They observe chemical and physical changes...
Curated OER
Egg Measurement
Students explore measurement and units. They measure eggs to determine their density, mass and percent composition. An inquiry approach is used for students to ascertain the mass.
Curated OER
TE Activity: Build Your Own Mobile
Young scholars inquire into how the center of mass is the key factor in designing cars. They construct an oddly shaped object and determine its center of mass. They find that engineers are able to predict how objects will behave while...
Curated OER
Ring Around the Rosie
Students work together to discover the concept of angular momentum. They participate in experiments in which they test rotation and relate it to an object's mass. They participate in a literacy activity in which they compare mythology...
Curated OER
Perching Parrot
Students explore the concepts of center of mass and static equilibrium by seeing how non-symmetrical objects balance. They also analyze why all forces on an object must cancel out exactly for an object to be stationary.
Curated OER
Galapagos Rift Expedition Come On Down!
Learners research the development and implementation of a research vessel/vehicle used for deep ocean exploration. For this oceanography lesson, students calculate the density of objects by determining the mass and volume.
Curated OER
Popcorn Neutrino Lab
Learners parcticipate in a modeling activity that simulates the cyclical role of experimental and theoretical science. Initially, students measure the mass of popcorn. They also record predictions of the mass of the kernels after they...
Curated OER
Density Lab
Students use an Excel spreadsheet to calculate the density various liquids. They take pictures of their results.
Curated OER
Robots from Junk
Pupils create balloon and rubber band models of robotic rovers to investigate the concepts of mass, torque, and friction. Through research and planning, students construct a rover test-bed that simulates the Martian environment.
Curated OER
Mass Matters
Fourth graders, in pairs, explore the relationship between a star's life and its mass. They use a concept map to illustration the three categories of stars.
Curated OER
Nature of Game Balls
Fourth graders see how, when balls are dropped from the same height, mass and size affects the motion of the balls.
Curated OER
Rockets
Learners explain the basics of rocketry and explain the relationships between mass, acceleration, and thrust.
