Students will begin this inquiry-based lesson by accessing their prior knowledge about the distinguishing characteristics of different substances. Using ideas from the students, the teacher will create a list of physical and chemical properties that can be used to recognize different substances. Next, the teacher will assist the students in planning an investigation that will test methods to determine the identity of substances based on their characteristic properties. Lastly, students will carry out the investigation they planned with the aim of identifying "mystery" substances using their unique physical and chemical properties. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

The Careers in Green Chemistry and Sustainable Design video series highlight professionals in Washington whose careers impact products or chemicals used in Washington. Each of these videos highlight a career that connects to green chemistry and sustainable design. In each video, the professionals share their reflections in response to a series of interview questions. The videos are five to ten minutes long. They are designed to be used with secondary students.
It includes an activity guide to support teachers with using the video series with students.

This activity is a lab where students make qualitative and quantitative observation on a chemical change. They will see that gases have mass in accordance with the conservation of matter.

Chemical reactions is one of the essential concepts in chemistry. This resource explains this concept by delivering examples taken from real life. The evidence of chemical reaction occurrence is discussed as well as the representation of this reaction by word equation.

This activity is an inquiry-based investigation where students discover the indicators of chemical reactions (endothermic and exothermic) by collecting data and using that data to develop a testable question for further experimentation.

This activity provides students with the opportunity to gather data from a controlled experiment setting, interpret their findings and use the data to draw conclusions to solve a mystery.

This is an activeinspire flipchart which could be used by teachers to explain the concept of chemical reactions or to assess students' prerequisites.

This activity is a classroom lab where students observe and classify chemical and physical changes using the five characteristics of a chemical change, interpret their findings, and use evidence to support their findings.

Matching game, including matching common ionic charges and ions and the compounds they form and naming of greek prefixes for covalent molecules.

This activity provides a demonstration and lab exploration of one of the main "building blocks" of the periodic table of elements: chlorine. During the lab, students compare physical and chemical properties of chlorine compounds.

Schrauben lösen, Kabel neu verlegen: Messer, Gabel und Pudelmütze werden zum Input für den Computer. Ziel ist es, neue Benutzerschnittstellen für den Computer zu entwickeln, indem die TeilnehmerInnen einen Blick "unter die Motorhaube" einer USB-Tastatur werfen. So können Jugendliche im Alter von 13 - 17 Jahren erste Schritte im kreativen Umgang mit Elektronik machen und dabei viel Spaß haben.

Voraussetzungen sind lediglich die Freude am Experimentieren und die Neugier, technologische Grundlagen spielerisch zu erlernen.

This activity is a lab designed for students to combust magnesium and use results to explain oxidation/reduction reactions.

This introductory class of computer skills is comprised of units that focus on basic computer hardware and the following applications: Word 2010, Excel 2010, PowerPoint 2010, Photo Gallery, and Audacity. Most units begin with YouTube overviews or 'how to' presentations followed by step by step guides to using aspects of the application and then have assessment exercises and conclude with a final project for evaluation.

Students investigate the property dependence between concentrations and boiling point. In section 1, students first investigate the boiling point of various liquid solutions. In section 2, they analyze data collected by the entire class to generate two boiling point curves, one for salt solutions and one for sugar solutions. Finally, in section 3, students use the data they have analyzed to determine how to create a solution that has a particular boiling point and is a cost-effective design.

Conditioning affects an animal's behaviour. Learn about classical and operant conditioning in this GCSE / K12 Ecology video from the Virtual School.

It this exercise the students will discover that pure water does not conduct electricity and that dissolving different substances in water may or may not cause it to conduct electricity.

Students develop and conduct an experiment using the law of conservation of mass to determine whether or not gum should be considered food. Students will compare the mass swallowed for sugar and sugar-free gum. This could be used to discuss solubility.

Using paper towels this activity introduces using the scientific method to set up and test and experiment.

Concluding a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate densities of several household liquids and compare them to the densities of irregularly shaped objects (as determined in Part 1). Then they create density columns with the three liquids and four solid items to test their calculations and predictions of the different densities. Once their density columns are complete, students determine the effect of adding detergent to the columns. After this activity, present the associated Density & Miscibility lesson for a discussion about why the column layers do not mix.
