Learners examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...
Curated OER
Surface Tension and 3D Soap Films
Students are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.
Curated OER
Beneath the Sea
Learners build a model of a submersible that will allow them to explore ballasts and how they operate. In this hands on instructional activity students participate in an activity that shows them how to control buoyancy.
Curated OER
Temperature School
Students observ the cooling and warming of room temperature, hot, and ice cold cans of water by measuring the change in temperature over time. They then attempt to develop explanations for the observations made and apply their findings...
Curated OER
Observing Objects
Learners observe the motion of both a pendulum and a spring pendulum . They then explain the differences and the similarities between the two types of motions.
Curated OER
Interdisciplinary Task: Weather
Learners design a chart to use to record the weather for five days. They then build an anemometer to record wind speed and discover why they are used for this purpose.
Curated OER
Predator/Prey Relationship
Students study and analyze data collected on the relationship between the snowshoe hare and lynx in Canada over a 28 year period and create a graph. Students also write a response to a proposal to reduce the lynx population.
Curated OER
Teaching the Bell Tetrahedral Kite
Students complete readings on kite making and kite flying. They analyze how the parts of a system interconnect and influence each other. Students identifies and uses color and form in a 3D artwork.
Curated OER
Airplane Wings
Students examine the aerodynamics of a wing and how it generates lift. In this flight lesson students complete several experiments including how to build a paper plane and how airfoils affect performance.
Curated OER
Exploring Balancing Forces
Learners develop critical thinking skills and explore the concept of force. In this balancing forces lesson students complete an activity and explain the conclusion.
Curated OER
Forces and Acceleration
Learners discover the relationship between force and acceleration in a skateboard experiment. In small groups, they attach a spring balance to a skateboard and pull a group member across the floor using a constant amount of force. They...
Curated OER
Measurement: Using the balance
Pupils use a balance and gram cubes to measure several different objects. They then record their results on a data chart and answer questions about them.
Curated OER
Newton's Third Law of Motion
Seventh graders are introduced to Newton's Third Law of Motion. In this physics lesson students examine the concept of thrust as one of the forces acting on aircraft.
Curated OER
MEASURING THE GRAVITATIONAL CONSTANT, G
Pupils study gravitational force an. In this gravitational force lesson students observe a demonstration.
Curated OER
Perching Parrot
Learners 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
Weightlessness
Eighth graders study weight, force and mass as it pertains to the earths pull. In this weightlessness lesson students are divided into groups and complete an activity.
Curated OER
The Pork With Torque
Students determine the torque of CEENBoTs wheel hub. In this physics lesson, students reinforce their learning by exploring interactive websites on torque. They give real life applications of torque.
Curated OER
Swinging on a String
Students explore how pendulums work and why they are useful in everyday applications. In a hands-on activity, they experiment with string length, pendulum weight and angle of release.
Curated OER
Avalanche!
Middle schoolers explain that when forces on an object are balanced, the motion of object does not change. They describe how an object changes its motion when forces on it are unbalanced. They plan and conduct a scientific investigation...
Curated OER
The Buoyancy Factor
Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...
Curated OER
Katrina Case Study: Watershed
Students explore the importance of the coastal wetlands. In this environmental lesson, students observe a model of wetland transformation over time. They discuss what changes occur in the wetlands and how hurricanes can affect the...
