In this exercise, sudents write a series of three stories that explain and/or illustrate rock-forming processes. As an alternative, they may write a single story that addresses the rock cycle. Describing these processes at a level appropriate for their target audience (second graders) requires an adequate understanding of the geologic processes involved and can reveal problems or misconceptions in the students' ideas of how rocks are formed. Teacher's notes and rubrics for teacher and peer review are provided.

In this exercise, students use U.S. Geological Survey and other websites to learn about the history of earthquakes in New York. Through their web research, they will learn what earthquakes are, how and where they occur, and the types of hazards associated with large quakes. They are encouraged to write a report summarizing their results.

This interactive resource adapted from the National Park Service profiles rocky coast environments and describes how various geologic features form.

In this video adapted from the Encyclopedia of Physics Demonstrations, learn how plotting the changes in an object's position on a graph can provide information about the object's motion.

Learn about rotational forces by watching astronaut Jeffrey Williams spin objects onboard the International Space Station in this interactive activity adapted from NASA.

In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios. This resource includes background information about the Coriolis effect and helpful hints.

How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.

This activity can be used to help middle and secondary school students develop more informed understandings of some important aspects of nature of science in the context of teaching them about Rutherford's experiments and atomic structure.

Audio drama que aborda conceitos introdutórios de geologia e reatividade dos metais por meio de uma história ficcional. 

This unit includes 10 lessons that culminate in a student created final product presentation on the factors that influence climate change through the lens of chemistry and oceanography using literacy strategies to conduct inquiry level research.

Using inquiry-based reading, student will examine an anchor text to formulate a question to guide their research and development of student driven projects. Throughout the unit, students will use a variety of texts, websites, and other resources to develop a product and presentation that exhibits their literacy and inquiry skills. Using inquiry-based reading, students will explore an anchor text and then develop their own essential and supporting questions to guide their research. Over the course of the unit, students will explore a variety of texts and grow in their knowledge of cellular organelles and in their ability to use informational text to support their inquiry and research.

The STEM Concept Videos are designed to help students learn a pivotal concept in science, technology, engineering, and/or mathematics (STEM). These ideas are the building blocks of many engineering curricula, and learning them will help students master more difficult material. The STEM Concept Videos were produced by the Teaching and Learning Lab (TLL) at MIT for the Singapore University of Technology and Design (SUTD).
For more information on how these videos were developed, please see the paper presented by TLL researchers at the American Society for Engineering Education (ASEE) 2013 conference.

In this lesson students will develop an evidence-based argument after investigating the product safety, performance, and cost of a variety of cleaning and disinfecting products designed to remove germs.  Students will be introduced to principles of sustainable design, life-cycle thinking, and how to identify safer products to certifications.Except where otherwise noted, this work by Saskia van Bergen (Washington Department of Ecology), Vickei Hrdina (ESD 112), and Carissa Haug (NCESD) is licensed under Creative Commons Attribution License 4.0.  All logos and trademarks are property of their respective owners.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

This animation adapted from NASA shows the orbital paths of spacecraft in NASA's Earth Observing Fleet that are a source of wide-scale, primary research about Earth.

There are many misconceptions about the chemistry concept, “Conservation of Mass”. Thus, the aim of this video lesson is to teach students about the chemical concept of Conservation of Mass through several chemistry experiments. The students will carry out experiments while assisting a fortune teller named Pak Belalang to gain victory for his kingdom. In an effort to help Pak Belalang, students should be able to answer all the questions related to the Conservation of Mass that are posed by an evil witch. In this video, materials such as a box of matches, a closed and open container, a box of panadol soluble tablets (Alka-Seltzer), and weighing scales are needed. At the end of the lesson, students will be able to see that mass is “conserved”. The lesson will take up to 60 minutes to complete.

This activity is a field investigation of puddles where students gather data and record their findings.
