Producing and Testing for Gases

Students investigate the spectroscopic colors unique to elements, and to use this information to create a specific color. They follow a detailed schematic to produce a spectroscpoe to be used in the testing.

Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both...

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Students participate in a lab activity in which they examine a simple energy transformation system. Students test the rebound of elastomers, produce rebound data, and determine the kinetic energy transformed by the impact of a free...

You may want to change the title of this chemistry PowerPoint to "Identifying Compounds in the Laboratory." Individual slides explain tests that can be performed to confirm what element you have: carbon dioxide, carbonates, and metal...

If most gases are invisible, how do we know so much about them? Pupils practice associating the name, formula, testing method, and outcome for four common gases using an interactive. Users build on the content of their first puzzles to...

How can a chemist tell what gas a chemical reaction produced? Part two of a ten-part series prompts pupils to discover a number of simple tests that can reveal the identity of a gas. The video reinforces the concepts of solubility,...

Scholars think color-change tests are the best! Show them how to differentiate between alkanes and alkenes using a short video. The narrator guides them through the test and the reactions that occur for alkenes. Other topics include...

Students design and make a flying device. They work in small groups to brainstorm ideas for the design of their device. They choose an idea or combination of ideas to use for their design and create a sketch of their design. The students...

Scientists identify elements by the color of flame they produce because each element is defined by exactly one line on the emission spectrum. By completing a series of puzzles, scholars reinforce their knowledge of the results of flame...
