Students construct three-dimensional models of water catchment basins using everyday objects to form hills, mountains, valleys and water sources. They experiment to see where rain travels and collects, and survey water pathways to see how they can be altered by natural and human activities. Students discuss how engineers design structures that impact water collection, as well as systems that clean and distribute water.

Authored by Belal Joundeya, the "Fly with Arabic" full text document is comprised of eight units, and features a variety of language-learning lessons tied together by fun themes, such as weather, sports, travel, school, and other hobbies and activities. The units focus on the acquisition of listening, reading, writing, and speaking skills, as well as knowledge of Arabic cultures and history.

Most units contain several lessons, including fill-in-the-blank exercises, open-ended writing practice, and word-matching games, that seek to reinforce specific learning outcomes, such as oral and written production, writing, and reading. Additionally, brief cultural drills are included in each unit, and are designed to add a cultural dimension to each unit's language activities. All units also contain self- assessment checklists to help monitor and measure the learner's progress during the unit.

In summary, through using a number of drills to produce vocabulary, grammar, reading, writing, and speaking skills, including pictures, word-matching games, open-ended writing practice, and fill-in-the-blank exercises, the "Fly with Arabic" series seeks to connect all phases of Arabic-learning into one comprehensive package.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Around 125,000 years ago Earth was relatively warmer than today All because Earth’s orbit permitted greater exposure to incoming solar rays This time period provides an example of how Earth’s climate might respond to future warming A recent study used fossil corals to explore past changes within the Tropical Atlantic a region sensitive to shifts in the rain belt that spans the equator Any effect this has on water bodies is captured within the reefs built by corals Oxygen isotopes within seven corals reveal 85 years of seasonal climate change Pairing the coral data with computer simulations showed the rain belt moved farther north bringing more summer rain to the islands of the South Caribbean, such as Bonaire in contrast to the dry weather found in the region today Brocas et al. Last Interglacial Hydroclimate Seasonality Reconstructed From Tropical Atlantic Corals..."
