In Visceral Science learners will have a chance to build stars, solar systems, and see how they end. To prepare them for this experience these short videos will introduce some important concepts like how stars & planets form, why planets stay in orbit, what happens when stars get older, and much more!
Estimated time required: 1-2 class periods.
Technology required for this lesson: Internet Connectivity, Laptop/Desktop or VR Headset, VR Headset (Optional).
Students are introduced to the concept of viscoelasticity and some of the material behaviors of viscoelastic materials, including strain rate dependence, stress relaxation, creep, hysteresis and preconditioning. Viscoelastic material behavior is compared to elastic solids and viscous fluids. Students learn about materials that have viscoelastic behavior along with the importance of engineers understanding viscoelasticity. To best engage the students, conduct the first half of the associated Creepy Silly Putty activity before conducting this lesson.
Students study the physical properties of different fluids and investigate the relationship between the viscosities of liquid and how fast they flow through a confined area. Student groups conduct a brief experiment in which they quantify the flow rate to understand how it relates to a fluid's viscosity and ultimately chemical composition. They explore these properties in milk and cream, which are common fluids whose properties (and even taste!) differ based on fat content. They examine control samples and unknown samples, which they must identify based on how fast they flow. To identify the unknowns requires an understanding of the concept of viscosity. For example, heavy cream flows at a slower rate than skim milk. Ultimately, students gain an understanding of the concept of viscosity and its effect on flow rate.
Students are introduced to the similarities and differences in the behaviors of elastic solids and viscous fluids. Several types of fluid behaviors are described Bingham plastic, Newtonian, shear thinning and shear thickening along with their respective shear stress vs. rate of shearing strain diagrams. In addition, fluid material properties such as viscosity are introduced, along with the methods that engineers use to determine those physical properties.
In this lesson, the electromagnetic spectrum is explained and students learn that visible light makes up only a portion of this wide spectrum. Students also learn that engineers use electromagnetic waves for many different applications.
In this ZOOM video segment, cast member Francesco follows the paper trail to find out what happens to his recyclables. He visits a material recovery center and learns how paper is recycled and the number of trees that are saved as a result.
In this adapted video segment, ZOOM guest Laura shows us some of the natural features of Yellowstone National Park, including geysers, hot springs, fumaroles, and mud pots, as well as some of the wildlife.
Students make simple spectroscopes (prisms) to look at different light sources. The spectroscopes allow students to see differing spectral distributions of different light sources. Students also shine a light source through different materials with varying properties and compare the differences.
This is a vocabulary building game based on matching words with definitions.
This interactive resource adapted from the National Park Service illustrates the difference between explosive and effusive volcanic eruptions as well as the hazards that can result, including lahars, tsunamis, and lava flows.
This interactive resource adapted from the National Park Service illustrates the variety of landforms and features created by volcanoes. Featured are calderas, craters, fumaroles and other geothermal features, igneous rocks, lava flows, lava tubes, and maars.
Ever wonder how a battery works? This segment highlights voltaic cells, their various components and how they operate.
In this video segment from TV411, WNBA player Olympia Scott Richardson discusses her techniques for effective time management.
In this podcast, learn about student misconceptions about heat and activities that target them.
Investigate the effect of gravity on objects of various mass during free fall. Predict what the position-time and velocity-time graphs will look like. Compare graphs for light and heavy objects. Was Galileo Right is the last of five SmartGraphs activities designed for a typical physical science unit of study on the motion of objects.
Students use inclined planes as they recreate the difficult task of raising a monolith of rock to build a pyramid. They compare the push and pull of different-sized blocks up an inclined plane, determine the angle of inclination, and learn the changes that happen when the angle is increased or decreased.
This review is on the first segment of the Grade 5 curriculum of "The Inquiry Project: Seeing the World Through the Scientists' Eyes." Water, A Liquid is a series of 5 investigations about water. Students use readily available materials such as water, sand and gravel to deepen their understanding of weight. Having a conceptual understanding of weight is important because students will use it when they begin exploring matter that is too small to be seen. The students are introduced to the study of matter by looking at images of ships sitting in a dry seabed in the Aral Sea. This introductory investigation will hook students because it is posed as a mystery and has a real life connection. Within this series of 5 investigations students will: -practice measurement using standard units -collect and record data -read a letter from an engineer -compare the weight of sand and water -use a digital scale -learn vocabulary -review volume, estimation -engage in discourse -reflect on the weight of small bits of matter -summarize evidence -collaborate -develop strategies -observe -transform (by crushing). The Inquiry Project is a quality curriculum developed pre-NGSS but closely aligned with The Framework of K-12 Science Education. This curriculum "links the three dimensions together" through the qualitative and quantitative measurement of water and sand using standard units and student observations. Each lesson is "designed to link with the previous lesson" as students build toward the capacity to be able to "make observations and measurements to identify materials based on their properties" in the context of the dry sea phenomena.
This activity investigates water when it freezes and how other solid items sink or float in water.
