- Energy Transfer
E3Energy TransferStudents explore the transfer of energy from place to place and form to form. They observe examples of energy transfer between light, heat, electrical, motion, and sound. Students have the opportunity to apply their understanding of energy transfer by building a solar oven. - Properties of Matter
E5Properties of MatterStudents understand what matter is, and what types of properties can be used to define different types of matter. They first explore properties of different types of matter through a hands-on investigation and then watch Dr. Jeff show off some exciting demonstrations of properties of matter. - Particle Nature of Matter
E10Particle Nature of MatterStudents model the structure of gases and other materials which are made up of particles too small to be seen, and use that model to explain properties of those materials. Students first physically model the particle nature of solid, liquid and gaseous phases of water, but move on to observations of phenomena can be explained through the particle model of matter. - Information Transfer
E11Information TransferStudents explore the science behind how devices like cellphones, tablets and computers transfer text, images and sound. Students delve into the history of information transfer by learning about Morse code as another example of using patterns to transfer messages. Students participate in hands-on experiences using both Morse code and patterns of zeros and ones to transfer information. - Patterns of Motion & Friction
E12Patterns of Motion & FrictionStudents think about motion that they have seen before, as well as observe and identify repeating patterns of motion. Students also recognize that the force of friction resisting an object’s motion can explain why that object slows or stops. They explore evidence for heat as a product of friction. - Renewable vs. Nonrenewable Resources
E13Renewable vs. Nonrenewable ResourcesStudents will discuss and analyze the types of fuel that are used to generate energy. In teams, students will design, build and present a renewable energy device. The class will list the pros and cons of non-renewable and renewable energy and discuss how and where renewable energy can be found and used in today’s society. - Weather vs. Climate
E15Weather vs. ClimateThe purpose of this lesson is to get students thinking about the types of data and tools that are useful for providing information to make predictions about the weather. While the main focus is weather, at the end of the lesson, climate is discussed as a way to build off of the students’ initial investigation. - Extreme Weather Solutions
E16Extreme Weather SolutionsStudents identify and explore extreme weather events most likely to occur in their area. Students explore cause and effect relationships between natural extreme events and the problems they can cause humans. They explore ways humans can reduce the impact of some natural hazards. Finally, students build a device that reduces the impact of extreme weather and then debate the merits of that solution. - The Sun and Other Stars
E25The Sun and Other StarsThe focus of this lesson is on the appearance of stars based on their size and distance from Earth. Central to this concept is recognizing our sun is a star as well. Students begin to comprehend the vast scale of the universe by comparing the brightness and sizes of stars in the night sky to our sun. - Interaction of Earth's Spheres
E26Interaction of Earth's SpheresThe Earth is constantly changing. To better understand the processes that change it we can visualize Earth as four interacting systems—the geosphere, biosphere, hydrosphere, and atmosphere. Humans are part of the biosphere, but have the ability to impact all of Earth’s spheres in both positive and negative ways. - What is Science?
E27What is Science?Learn about the practices of science, what science is, different fields in science, and how to think like a scientist. Students will determine how they use science and engineering practices when they conduct a test of their team design in the Egg Drop Challenge. Prior to this, students should be able to ask questions of each other about what they read and observe, and the conclusions they draw from scientific investigations. - Earth's Landscapes
E29Earth's LandscapesIn this lesson students will explore their own landscape for evidence to determine whether it has changed or remained the same over time. Students observe a similar investigation in another location, and then use local resources to learn more about where they live. - Variation of Traits
E33Variation of TraitsIn this activity students recognize that offspring don’t all look alike, and variation can also be observed between offspring and their parents. They learn that traits are passed from parents to offspring and that offspring have different traits from each other. Also some traits are caused by the environment. - Food Webs
E35Food WebsIn this video, students explore interactions between organisms and their environment. Specifically they study food chains and how those food chains connect to form webs. They explore the roles of different plants, animals, and other organisms in population control and recycling. - Ecosystems
E36EcosystemsIn this activity students learn that an organisms can only survive in an ecosystem where its needs are met. They explore a variety of different ecosystems and study the interaction between living things and non-living things, such as soil, water, and air. They also think about changes in ecosystems and the impacts they have on living things.
