In this activity, students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas produced from a chemical reaction between an antacid tablet and water to propel it. Students observe the effect that surface area of this simulated solid rocket fuel has on thrust.
Working as if they are engineers who work for (the hypothetical) Build-a-Toy Workshop company, students apply their imaginations and the engineering design process to design and build prototype toys with moving parts. They set up electric circuits using batteries, wire and motors. They create plans for project material expenses to meet a budget.
In the everyday electrical devices we use calculators, remote controls and cell phones a voltage source such as a battery is required to close the circuit and operate the device. In this hands-on activity, students use batteries, wires, small light bulbs and light bulb holders to learn the difference between an open circuit and a closed circuit, and understand that electric current only occurs in a closed circuit.
Elementary grade students investigate heat transfer in this activity to design and build a solar oven, then test its effectiveness using a temperature sensor. It blends the hands-on activity with digital graphing tools that allow kids to easily plot and share their data. Included in the package are illustrated procedures and extension activities. Note Requirements: This lesson requires a "VernierGo" temperature sensing device, available for ~ $40. This item is part of the Concord Consortium, a nonprofit research and development organization dedicated to transforming education through technology. The Consortium develops digital learning innovations for science, mathematics, and engineering.
Students learn about using renewable energy from the Sun for heating and cooking as they build and compare the performance of four solar cooker designs. They explore the concepts of insulation, reflection, absorption, conduction and convection.
“Circuit” comes from the same root word as “circle” because of the way a circuit works. A wire, connected to a power source, makes contact with a device requiring power to function or operate. A second wire runs from the device back to the power source. These connections make a pathway, allowing electrons to flow through the “circle” of wires.
In this unit of study students learn about energy and energy transfer. They focus on how to use energy transfer to solve a problem. This unit integrates nine STEM attributes and was developed as part of the South Metro-Salem STEM Partnership's Teacher Leadership Team. Any instructional materials are included within this unit of study.
Students use electricity every day. It is important to know how it works. Why does the light come on when they flip the switch? With a simple knowledge of circuits, students will understand how electrical energy moves from one place to another. Students will provide evidence to describe why the light bulb turned on, including the idea that energy can be transferred from place to place by electrical currents.
This lesson introduces electricity, batteries and motors using a LEGO® MINDSTORMS NXT® robot. The associated activity guides students to build a simple LEGO NXT set-up and see the practical implementation of the concepts discussed. Before studying the importance of electricity and how it is crucial for robot movement, students consider various electronic devices they use in their daily lives so that they have an understanding of how engineers use electricity to power such devices, including robots. The lesson starts with a brief introduction to electricity and the working of batteries. A simple electrical circuit demonstration highlights how three basic electrical devices (buzzer, LED and motor) are driven by electricity. An activity at the end further reinforces these concepts.
A lesson plan for 4th grade science. Kids create a version of the marble roll project to simulate a manufacturing process.
As part of a design challenge, students learn how to use a rotation sensor (located inside the casing of a LEGO® MINDSTORMS ® NXT motor) to measure how far a robot moves with each rotation. Through experimentation and measurement with the sensor, student pairs determine the relationship between the number of rotations of the robot's wheels and the distance traveled by the robot. Then they use this ratio to program LEGO robots to move precise distances in a contest of accuracy. The robot that gets closest to the goal without touching the toy figures at the finish line is the winning programming design. Students learn how rotational sensors measure distance, how mathematics can be used for real-world purposes, and about potential sources of error due to gearing when using rotation sensor readings for distance calculations. They also become familiar with the engineering design process as they engage in its steps, from understanding the problem to multiple test/improve iterations to successful design.
In this unit of study students learn how to design vehicles using different forms of energy to solve real-world problems. This unit integrates nine STEM attributes and was developed as part of the South Metro-Salem STEM Partnership's Teacher Leadership Team. Any instructional materials are included within this unit of study.
This activity helps students understand how a motor in a LEGO MINDSTORMS(TM) NXT robot uses electricity produced by the battery to move a robot to do useful work in the form of throwing a ball. Students relate the concepts of electricity and battery to the movement of the LEGO NXT motor and connected links.
As the item moves through the contraption, energy is transferred from one object to the next, moving each one.
Designing something that works often takes many attempts, tests, and redesign. The final creation is often a combination of aspects of those many previous designs.
In this activity, students will use their knowledge of area and perimeter to create a racetrack. Once they have the correct specifications they will guide their car through the track using the properties of magnets.
Unit Goals: By the end of the unit, students should be able to combine some or all of the following ideas to explain the flashlight phenomenon or other related events.PS3.A Definitions of energyPS3.B Conservation of energy and energy transferPS3.D Energy in chemical processes and everyday lifePS1.A Structure and Properties of MatterPhenomenon & Anchoring Question Phenomenon: [Mr./Ms.Teacher] accidentally shoves the flashlight in a desk drawer and the switch gets flipped on. The flashlight stays on inside the desk for a whole month (30 days). When [Mr/Ms. Teacher] goes to use the flashlight it doesn’t work anymore. What happened? What caused it to stop working? What’s happening inside the flashlight or parts of the flashlight that might cause it to stop working?Question: Why would a flashlight eventually stop working if it were accidentally left turned on for a period of time?
Students build their own two-cell batteries. They also determine which electrolyte solution is best suited for making batteries.
Students observe a model waterwheel to investigate the transformations of energy involved in turning the blades of a hydro-turbine. Students work as engineers to create model waterwheels while considering resources such as time and materials, in their design. Students also discuss and explore the characteristics of hydropower plants.
Students learn the history of the waterwheel and common uses for water turbines today. They explore kinetic energy by creating their own experimental waterwheel from a two-liter plastic bottle. They investigate the transformations of energy involved in turning the blades of a hydro-turbine into work, and experiment with how weight affects the rotational rate of the waterwheel. Students also discuss and explore the characteristics of hydroelectric plants.
