This short document promotes creating presentations using Haiku Deck, a tool for making slideshows. It encourages the reader to get started making their own Haiku Deck presentation and sharing it on 際際滷Share. In a single sentence, it pitches the idea of using Haiku Deck to easily design presentations.
Laura was making a jello mold for Christmas but forgot to buy mandarin oranges. She substituted fresh pineapple instead, not realizing that pineapple contains an enzyme called bromelain that prevents jello from setting. When she checked on the mold later, it was still liquid. Some online research revealed that bromelain degrades gelatin, the protein in jello. Canned pineapple can be used instead because its bromelain enzyme is deactivated during the canning process.

The document discusses how to teach listening in three phases: pre-listening, while-listening, and post-listening. In the pre-listening phase, teachers activate students' background knowledge to prepare them for the listening text. During the while-listening phase, teachers guide students as they respond to the text through activities. In the post-listening phase, students reflect on and discuss the language form through tasks like dialogues and writing assignments based on the text. Overall, the document provides guidance on listening instruction strategies and activities teachers can use in each phase of listening.
The document discusses the theory of superconductivity. It begins by reviewing key experiments that established the phenomena of superconductivity, superfluidity, and Bose-Einstein condensation. These include the discovery that the resistivity of mercury abruptly drops to zero at 4.1K, demonstrating superconductivity. It also describes the Meissner effect, where superconductors expel magnetic fields from their interior. The document then discusses conventional superconductors and their properties, such as an abrupt resistivity transition and phase diagrams showing normal and superconducting regions.
