By watching and performing several simple experiments, students develop an understanding of the properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.
Student groups compete to design a process that removes the most iron from fortified cereal. Students experiment with different materials using what they know about iron, magnets and forces to design the best process for removing iron from the cereal samples.
Students will participate in a demonstration that will show the interconnectedness of a food web such that when one component is affected, the whole web is affected in some way. This is important for students to understand, as we are part of food webs and we need to be thoughtful about our decisions.
To better understand electricity, students investigate the properties of materials based on their ability to dispel static electricity. They complete a lab worksheet, collect experimental data, and draw conclusions based on their observations and understanding of electricity. The activity provides hands-on learning experience to safely explore the concept of static electricity, learning what static electricity is and which materials best hold static charge. Students learn to identify materials that hold static charge as insulators and materials that dispel charge as conductors. The class applies the results from their material tests to real-world engineering by identifying the best of the given materials for moving current in a solar panel.
This is the first instructional sequence in a teacher's guide built with the purpose of helping students build a deeper understanding of the Structures and Properties of Matter standard.Students have the opportunity to engage with interactive simulations, create poetry, drawing scientific diagrams, read complex text, develop evidence based explanations and design a model . The instructional sequence described in the lesson uses the 5 E learning model and includes a variety of online simulations, polls and model drawings.

Students are introduced to the concept of electricity by identifying it as an unseen, but pervasive and important presence in their lives. They are also introduced to the idea of engineers making, controlling and distributing electricity. The main concepts presented are the science of electricity and the careers that involve an understanding of electricity. Students first review the structure of atoms and then learn that electrons are the particles behind electrical current and the motivation for electron movement. They compare conductors and insulators based on their capabilities for electron flow. Then water and electrical systems are compared as an analogy to electrical current. They learn the differences between static and dynamic forms of electricity. A PowerPoint(TM) presentation is included, with review question/answer slides, as well as assessment handouts to practice using electricity-related terms through storytelling and to research electricity-related and electrical engineering careers.
