Density of Common Liquids
Do different liquids have different densities? How can we tell? Using measurement, mathematics, and the scientific method, young scientists discover the answers to these questions. With some simple lab equipment and common household liquids, middle schoolers put their skills to work to find out which liquids are denser than others. To enhance the activity, have pupils write up a lab report and communicate their results with the class.
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.
Students explain the role of convection currents in the movement of air. In this earth science lesson, students investigate convection by observing a boiling water in the lab. They describe how fluids move when they experience convection.
The Mathematics of Convection: Nature's Model for Energy Production
High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math lesson, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.
Conduction, Convection, Radiation, Oh My!
Students draw a line graph, and use graphing as a tool to discover more about conduction, convection and radiation. They should design their own experiment using heat sensitive paper to show they explain these 3 processes.
Convection in a Pan
Students explore convection. In this lesson on heat and energy, students investigate how heat moves in convection currents. They use their finding to better understand how convection currents effect the movement of tectonic plates.
Sixth graders work together to show convection currents in the air. They construct a paper propeller that be caused to spin due to the transfer of heat energy through the air.
Convection and Wind
Young scholars use water, beakers, hot plates, paper dots, and goggles to participate in a hands on activity where they see how a convection current creates wind. In this convection current lesson plan, students participate in a hands on activity to see how the hot water molecules move substances.
How Hot is Hot?
Elementary schoolers identify the three methods of heat transfer: conduction, convection, and radiation. The lesson is mostly lecture-based. When the teacher has finished the presentation, groups of pupils get into teams and they must work together to answer questions posed by the teacher (and embedded in the plan), which will serve to reinforce what they have heard during the lecture. Some terrific extension activities and websites are also present.
Students experiment with the cyclic process of convection and apply the principal to everyday events.
Learners explore weather by completing a worksheet in class. In this geology lesson, students discuss the traveling of heat through convection currents and complete a model activity using a beaker, water and hot plate. Learners complete an Earth science worksheet and define vocabulary terms.
Sixth graders use jars of water, parsley and heating plates to observe convection currents. They discuss the demonstration and consider how their observations might apply to architecture and building design.
Conduction, Convection, or Radiation?
Young scholars read "The Hottest Boy Who Ever Lived" by Anna Fienberg and then identify and discuss types of heat transfer including conduction, convection and radiation. They match actions in the book to types of heat transfer.
How Hot Is It?
Discuss the difference between conduction, convection and radiation of thermal energy, and complete activities with your class by investigating the difference between temperature, thermal energy and the heat capacity of different materials.
In this thermodynamics worksheet, students learn about insulators and conductors. Students compare the three ways thermal energy is transferred: conduction, convection, and radiation. This worksheet has 22 matching, 1 multiple choice, 3 fill in the blank, and 4 short answer questions.
Heat Up the Floating Plates
Eighth graders investigate the moving of the Earth's plates. In this lithospheric plate movement lesson, 8th graders investigation the connection between the moving of the Earth's plates and the convection currents within the mantle.
Thermal Physics / The Saga Continues - Heat Transfer
Somebody in the Nevada Joint Union High School District has a talent for focusing the important, organizational skills, and a creative eye for creating sharp science presentations! Here is one on heat transfer. Conduction, convection, and radiation are explained at the level of high school physicists, but in such an orderly and cohesive manner that viewers feel no heat! By the end of the slide show, learners are able to explain the three types of transfer, calculate transfer rates, and relate radiation to temperature.
Density Phenomena-Using the Concept of Density
Students investigate the concept of density by observing demonstrations. In this density lesson plan, students make observations while the teacher demonstrates the Cartesian diver, a density column, a candle trough, a wave bottle, an inverse wave bottle, a U-tube density trick, convection currents and floating balloons. Students take notes and explain their observations for three of the demonstrations.
Density of Common Liquids
Eighth graders demonstrate their ability to measure accurately, and collect and record data, as each lab team determines the density of water and one of the sample liquids.
Amazing Liquid Conductor
Learners mix a variety of liquid solutions to see if they light a light bulb in an electrical circuit. They identify liquid electrical conductors and nonconductors. They make a closed circuit to test their solutions.
