Producing and Testing for Gases

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...

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...

Nine questions about gases allow your advanced chemistry class to apply what they have learned about the behavior of gases. Problems are solved using all of the gas laws. The format is tidy and allows plenty of space for problem solving....

Is assembling the periodic table as simple as Tetris? Scholars arrange colored cards into a logical order and then make connections to the arrangement of the periodic table. Hands-on activities include adding trend arrows and analyzing...

One way to identify possible volcanic activity on other planets is by testing the planet for magnetism. A science lesson begins with pupils constructing their own planet from a dead battery, magnets, paper, and tape before labeling the...

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...

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...

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,...

How do we know when water is safe to drink? Part seven of a 10-part videos series uses water quality as a platform to explore the behavior of halide ions in solution, Further tests help learners differentiate between precipitates that...

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...
