Suspension Bridge Construction
Students study types, strength and construction of a variety of bridges. They build a model bridge and test the amount of weight it support.
Curated OER
Diving Raisins
Students hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.

Hover Above the Earth
Fourth graders build a balloon hovercraft, take direct measurements, answer critical questions, and make calculations using the data gathered in order to see the concept of acceleration as a change in velocity. They use a worksheet...
Curated OER
Molecules Rock
Fourth graders engage in this interactive lesson which illustrates diffusion and osmosis and shows them that molecules of life move dynamically and powerfully. They must analyze their lab orally and in writing.
Curated OER
Pulley Power
Third graders engage in a manipulative experiment in the mechanical advantage of simple machines. It graphically demonstrates the change in magnitude of applied force when using simple machines. Great for ESL to discover the ratio...

Who's the Frog Jumping Champion?
Students use a simple machine (a lever) to launch a plastic frog. students determine who is able to make their frog "jump" the farthest and graph the results.
Curated OER
Machines Help
Fourth graders review the six simple machines, and locate simple machines on the school grounds. They chart what machines are found and how they are used to make tasks possible.
Curated OER
Balloonautics
Young scholars are introduced to basic aerodynamics through a discussion of thrust and drag and a hands-on activity. They examine the forces of thrust, drag, air pressure, aerodynamic shapes and Newton's Third Law Of Motion.
Curated OER
Air and Water Pressure
Students examine buoyancy and fluid pressure. They conduct a series of fun experiments to discover the effects of pressure and explore how pressure differences can be used to float, lift, transport, or hold a material in place.
Curated OER
Electricity
Students examine basic electrical components. They build a simple electrical circuit which rings a buzzer. They experiment with conducting and nonconducting materials.
Curated OER
What Does It Matter?
Students match definitions with vocabulary words and learn basic facts about matter. Then, they see how to determine the physical characteristics of matter. They determine the mass, volume, and density of objects using appropriate tools...
Curated OER
Chromatography
Young scholars study about chromatography, a process used to separate mixtures.
Curated OER
T-shirt Chromatography
Young scholars explore chromatography, a process used to separate mixtures. They create a colorful T-shirt design.
Curated OER
Bridge Construction
Students build a model of a bridge and test the amount of weight it support. They identify different types of bridges: suspension, arch, girder, truss, cantilever, cable-stayed and moveable.
Curated OER
Flowing Electrons
Students act out different types of circuits, and create their own circuits using wire, a bulb, a battery and a switch.
Curated OER
Ramps 1: Let It Roll!
Students explore and measure the rate of spherical objects rolling down a ramp. They discuss why different ramps work better than others, and practice procedures for testing designs and recording results.
Curated OER
Ramps 2: Ramp Builder
Students plan, build, and test a ramp that allows objects to roll far. After each group has tested out their ramps, allow them to test their design against the record previously established by the prototype ramp.
Curated OER
Newton's Laws and Winter Sports
Students investigate past winter Olympic games utilizing any skiing or snowboarding event to take Newton's Challenge. Helpful Web resources are provided and students enjoy learning science laws along with researching Olympic events.
Curated OER
Properties of the Ocean: Measurement
Students simulate the development of an underwater amusement park after reading background on Coral Reef State Park. They decide which factors they would need to consider such as the ocean floor, currents, wave patterns and water...
Curated OER
Fulcrums in Our Body
Second graders discuss fulcrums and levers and identify at least two fulcrums and levers on their bodies. They also identify fulcrums and levers on animal bodies.
Curated OER
Air Movement
Learners observe a series of teacher-led demonstrations about air movement. They explain the existence and movement of air, then list 3 things that they have learned about air. Finally, students go outside and shoot off air cannons.
Curated OER
As a Matter of Fact
Young scholars rotate through various hands-on experiment stations to explore the concept and properties of different types of matter. They compare some properties of solids, liquids and gases and describe how matter changes from one...
Curated OER
Attract or Repel?
Students explain why some objects attract and some do not. For this physics lesson, students investigate the magnetic properties of objects using CEENBoT. They give some important applications of magnets.
