Producing and Testing for Gases

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 plan begins with pupils constructing their own planet from a dead battery, magnets, paper, and tape before labeling...

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...

Ozone, made of three bonded oxygen atoms, is found 15-30 km above Earth, has a strong smell, is blue, and blocks sunlight from hitting the surface of Earth. The 22nd lesson in a series of 36 specifically focuses on the important elements...

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...

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...

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...

The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the results...
