FOSS Mixtures and Solutions Module Glossary Science is a rich content area for
developing language concepts and vocabulary. While conducting FOSS
investigations,
students are involved in observing properties, comparing and organizing their
observations, and identifying relationships from their observations. In order
to effectively communicate the results of their investigations, it
is important
to use concise and appropriate vocabulary. Students need to develop a sound
vocabulary that will serve them in science and life. Some of the vocabulary is introduced and reviewed with students in the Wrapping Up section of the investigation folio in the Teacher Guide. These are listed below and identified with the abbreviation TG. Additional words are introduced and included FOSS Science Stories glossary. These words are identified with the abbreviation SS.
