This activity introduces students to different forms of energy, energy transformations, energy storage, and the flow of energy through systems. Students learn that most energy can be traced back to nuclear fusion on the sun.

See potential energy convert to kinetic energy in this interactive activity from WGBH that shows a roller coaster in action.

Under the "The Science Behind Harry Potter" theme, a succession of diverse complex scientific topics are presented to students through direct immersive interaction. Student interest is piqued by the incorporation of popular culture into the classroom via a series of interactive, hands-on Harry Potter/movie-themed lessons and activities. They learn about the basics of acid/base chemistry (invisible ink), genetics and trait prediction (parseltongue trait in families), and force and projectile motion (motion of the thrown remembrall). In each lesson and activity, students are also made aware of the engineering connections to these fields of scientific study.

High school science teacher Kate Summers has her students work collaboratively to create technology-enhanced presentations on basic chemistry concepts. Students work in pairs to develop a chemistry lesson to teach to their peers. Each pair's presentation needs to have a visual, a handout, and an engaging interactive activity. As they work, students use Google Docs and Google presentations. Kate explains how using Google Docs enables students to work collaboratively from different places and allows teachers to check in on their students' work. After planning their lessons, each pair delivers their presentation to the class.

This semester-long project on conducting an environmental audit of a college campus can be done by an individual or by groups of students working in teams. Each group will research a different aspect of campus operations; they will collect data, analyze their findings, and make recommendations for improvements. This SERC Starting Point site includes learning goals, context for use, teaching tips and materials, assessment, and references.

Students are introduced to the fundamentals of environmental engineering as well as the global air, land and water quality concerns facing today's environmental engineers. After a lesson and activity to introduce environmental engineering, students learn more about water chemistry aspects of environmental engineering. Specifically, they focus on groundwater contamination and remediation, including sources of contamination, adverse health effects of contaminated drinking water, and current and new remediation techniques. Several lab activities provide hands-on experiences with topics relevant to environmental engineering concerns and technologies, including removal efficiencies of activated carbon in water filtration, measuring pH, chromatography as a physical separation method, density and miscibility.

In this interactive activity a user identifies two pairs of equivalent fractions for a given random fraction or one of the player's own and the user creates their representations by dividing and shading either a square or circular region. The fractions are shown as locations on the number line and their equivalency is demonstrated when they are at the same point. The user has the ability to construct a table of equivalent fractions. Instructions and exploration questions are given.

These flow charts show carbon dioxide emissions for each state, the District of Columbia and the entire United States. Emissions are distinguished by energy source and end use.

This is a semester-long jigsaw project in which students work in teams to explore the effects of energy resource development on local water resources, economics, and society. Students are presented with a contemporary energy resource development issue being debated in their community. They research the water, geological, economic, and social impact of the project, and then either defend or support the development proposal.

In this activity, students learn about the pros and cons of co-firing woody biomass fuels with coal to produce electricity.

In this NASA video, scientists describe how the Extreme Ultraviolet Variability Experiment will sample and track the Sun's ultraviolet irradiance, providing a detailed time sequence of extreme ultraviolet output -- data that can provide advance warning for potentially disruptive energy bursts.

This lab activity leads students to a better understanding of exo-endo- thermic processes. It also reinforces the necessity for proper lab safety equipment and disposal techniques.

In this activity, learners use pattern blocks and mirrors to explore symmetry. Learners work in pairs and build mirror images of each other's designs. In doing so, learners will examine principles of symmetry and reflection.

This activity allows children to explore the effects of oil spills on birds.

This activity is a laboratory activity where students gather data relating quantities of salt to the freezing point of water/ice.

This lesson plan provides the teacher with an activity for introducing the game Krypto, which helps to develop number sense, computational skill, and an understanding of the order of operations. Players are given five number cards. They combine them, using the standard arithmetic operations, to create a target number. As students investigate the game, they develop strategies for finding solutions efficiently. The plan includes learning objectives, materials needed, questions to ask students, assessment options, extensions, teacher self-reflection questions, and a link to the online version, Primary Krypto, (catalogued separately).

This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.
