SANTILLANA USA - ES HS Teacher Guide Sampler Level 1 -2018

179 Picture Discussion . Use the photos to have students share any information they have on the four topics. Some general questions are: – What do you know about San Juan? – Have you heard of the coquí frog? – What do you know about bioluminescent bays? – What do you know about underground rivers? El Viejo San Juan . Ask students what they can tell about El Viejo San Juan based on the first photo. Are there any features that tell us about San Juan’s colonial heritage? El coquí . Ask the class to tell what kind of animal is in the photo. Does it seem big or small? Is this type of animal a likely choice to represent a tropical island? Ask students if they know what animal and flower are used as their state symbol. La bahía bioluminiscente . Can students name any other bioluminescent animals? What can students tell about this bay from the photo? Where is it located and what other animals could possibly live around this bay? Las cuevas de Camuy . Ask students to comment on the features of the caves that they can see in the photo. Has anyone explored above — or underground caves in the past? Can anyone explain why people may not explore underground caves as much as those above ground? Objectives . The overall objective of Unit 2 is for students to learn to talk about where they live and about daily household chores, as well as some activities done in their leisure time. . By the end of the unit, students will be able to – Express existence (there is /are) of people and things as well as their location. – Talk about daily activities and household chores. – Express an obligation related to chores. . To get started, ask students how they describe houses and other places where people live. What are the types of words one uses to talk about places? Las cuevas de Camuy These caverns were formed by the Camuy River that flows through them. Untouched for centuries after the native Taino people used them, the caverns were re-explored in the 1950s. This underground river and cavern system is among the longest in the world. Underground rivers and cave systems have been explored less than those above ground because of the difficulties in reaching those areas and the dangers associated with underground exploration. A species of blind fish lives in the caves. If there is no light, fish have no use for eyes as sensory organs. La bahía bioluminiscente Bioluminescence is the light that comes from living creatures (from the Latin lumen , meaning “light”). There are many animals that give off light, such as fireflies. In a few places on Earth, given very special conditions, one is able to see light coming from the waters of the ocean and bays. Microorganisms that give off light use it as a defense mechanism. The motion in the water from a predator triggers the light, which in turn attracts bigger fish that eat the smaller ones that feed on microscopic organisms. It takes special equipment to photograph bioluminescence. 8 Puerto Rico Unit 2 DESAFÍO 3 DESAFÍO 4 La bahía bioluminiscente 25 ochenta y siete 87 To express obligation or necessity Vocabulario Actividades de ocio Gramática Expresar obligación: – Tener que + infinitivo – Hay que + infinitivo Adverbios de frecuencia Las cuevas de Camuy DESAFÍO 4 To express habitual actions Vocabulario Las tareas domésticas Gramática Verbos regulares en - ar Verbos regulares en - er y en - ir a ahí i l mi i cente 3 DESAFÍO 300347 _ 0112-0169.indd 113 27/12/10 15:25 La bahía bioluminiscente Bioluminescence is the ligh that comes from living creatures (from the Latin lumen , meaning “light”).
