an dulce means "sweet bread" in Spanish and comes from Mexico. There are many different kinds of pan dulce. In this poem by René Saldaña Jr., the speaker tells about the different kinds of pan dulce cooked by their grandmother.

Science experts in the U.S. Virgin Islands presents Keeping our Coastlines Clean a U.S. Virgin Islands Marine Debris Curriculum Adapted from Oregon Sea Grant Marine Debris STEAMSS curriculum and NOAA curricula "Turning the Tide on Trash" and "Talking Trash and Taking Action."

The curriculum includes 15 spotlights, which highlight USVI-specific marine debris research, local researchers, community-led prevention efforts and natural disaster impacts from marine debris, specifically Hurricanes Irma and Maria, which impacted the U.S. Virgin Islands community as two category 5 storms in September 2017. Users can review and utilize lessons aligned to Next Generation Science Standards beginning on page 9 of the document.

Martin Luther King, Jr. (1929-1968) was an American Baptist minister and activist who became the most prominent leader of the Civil Rights Movement. He was known for his use of nonviolent civil disobedience to protest against racial injustice. In 1964, King was awarded the Nobel Peace Prize for his contributions to the Civil Rights Movements.

As you read, identify and take notes on examples of figurative language in King’s speech, as well as how they contribute to an understanding of racial inequality in America.

Students learn about the techniques engineers have developed for changing ocean water into drinking water, including thermal and membrane desalination. They begin by reviewing the components of the natural water cycle. They see how filters, evaporation and/or condensation can be components of engineering desalination processes. They learn how processes can be viewed as systems, with unique objects, inputs, components and outputs, and sketch their own system diagrams to describe their own desalination plant designs.

Students build a saltwater circuit, which is an electrical circuit that uses saltwater as part of the circuit. Students investigate the conductivity of saltwater, and develop an understanding of how the amount of salt in a solution impacts how much electrical current flows through the circuit. They learn about one real-world application of a saltwater circuit — as a desalination plant tool to test for the removal of salt from ocean water.

Students use a thermal process approach to design, build and test a small-scale desalination plant that is capable of significantly removing the salt content from a saltwater solution. Students use a saltwater circuit to test the efficiency of their model desalination plant and learn how the water cycle is the basis for the thermal processes that drive their desalination plant.
