Friends of the Los Angeles River Source to Sea Education Program Topic: Human Impact on the LA River: Past, Present, and Future Subject. Social Studies/Life Science Lesson No. 1 Grade. 3 California Common Core State Standards Abbreviations CCSS: California Common Core Standards L: Language Standards RI: Reading Standards for Informational Text SL: Speaking and Listening Standards W: Writing Standards CA STANDARD. Common Core & NGSS TIES. SS 3.1.2 Trace the ways in which people have used the resources of the local region and modified the physical environment (e.g., a dam constructed upstream changed a river or coastline). CC RI.3.7. Use information gained from illustrations…(e.g.,…photographs)…to demonstrate understanding of the text (e.g., where, when, why, and how key events occur) Pre-Planning Life Sci. 3d. Students know when the environment changes, some plants and animals survive and reproduce; others die or move to new locations. VOCABULARY. Biodiversity Web of life Tongva Habitat Native / non-native / invasive System Scientist: anthropologist, chemist, biologist, archaeologist . Please reference these throughout the lesson. They will be used in the next lessons. SL.3.1. Engage effectively in a range of collaborative discussions (…in groups…)…, building on others’ ideas and expressing their own clearly. W.3.8. Recall information from experiences or gather information from print…sources; take brief notes on sources and sort evidence into provided categories. NGSS 3-LS2-1: Cause and effect relationships are routinely identified and used to explain change. LS2.C: Habitat Dynamics, Functioning, and Resilience When the environment changes in ways that affect a place’s physical characteristics, temperature, or availability of resources, some organisms survive and reproduce, others move to new locations, yet others move into the transformed environment, and some die. (secondary to 3-LS4-4) OBJECTIVE. CONNECTION TO THE BIG IDEA/ RIVER. Students can explain and illustrate the interconnected relationship between living organisms in the River habitat. We are all interconnected. A missing link in a system has disastrous consequences. Humans have the ability to change the present and future of their environment. What will your students be able to do? ASSESSMENT. How does the objective connect to the big idea? (please share your assessment results & notes in FoLAR Feedback section) How will you know whether your students have made progress toward the objective? How and when will you assess mastery? Pre-Planning Compare results from formative and summative assessments at the end of lesson #3. Assess if students meet the objective of the lesson through the exit slip/closing questions. Students will share answers with class, provides insight into student comprehension and misconceptions in a check for understanding (CFU) by teacher during the lesson. Teacher will provide feedback on success and areas of growth for FoLAR (see feedback form). KEY POINTS. What three-five key points will you emphasize? Biodiversity is affected by a change in the River web of life; this change can be attributed to human impact (cause and effect relationships). We live on the same land as the Tongva did, but have much less biodiversity due to human impact. Human impact has altered the environment and affected organisms’ ability to reproduce and survive. o More in L#2 Rover: Human impact affects biodiversity. Native species (like the ones on the biodiversity cards) have been replaced by non-native and invasive species that adapted to the changing environment. Tongva thrived on the resources of the River and coexisted with the habitat. o This will be a stark contrast to what we have done to the River in the last 200 years. The Rover focuses on the 1900s to present. Pre-planning for Lesson Projector for visual aids Timer - recommended to keep activities moving!

Explain the background* of the Tongva’s life on the River while displaying Visual Aid PDF #5-#6. Projector Vocabulary box on G.O. Timer/watch Visual Aid #5 and #6 *See the Content Background at the end of this lesson plan in “Introduction to New Material”. Go over vocabulary words with students (definitions are provided). Biodiversity Web of life LESSON- CYCLE Model using the vocabulary G.O. Explain to students that they will be using these words when they learn about the River (Class-made visual of G.O. #1: Post for reference). Students TPS (Think Pair Share) with the student next to them and answer (allow approx. 15 seconds) Visual Aid PDF #7: What are 3 different things you use that come from plants or animals? Class-Made Visual Aid/Artifact Post vocabulary G.O. in the classroom. TPS: Give students a few seconds to think, then turn to a partner to discuss. This is a fast paced activity and should be timed. Chemist Ask two students to share with class. OPENING (_10 _min.) Display Visual Aid PDF #1- #4 and tell students that they will be learning about the LA River; past, present, and future. Students will explore the present state of the river on the River Rover and will be visiting the LA River on a field trip. Explain that students will answer some questions (Formative Assessment) to show what they already know about the LA River (students should be able to answer these questions at the end of L#3). Students take the formative assessment individually. ---------- MATERIALS. Projector Visual Aid PDF #1 - #4 L#1 Graphic Organizer (G.O.)/worksheet Collect Formative assessment as soon as it is completed. Students do not need to take a long time on it as it is measuring prior knowledge. Pass out L#1 Graphic Organizer/worksheet Students read objective (on graphic organizer) as a class. LESSON- CYCLE Display Visual Aid PDF #5-#6 (keep this short, no more than 45s) Students record observations of images and imagine what they might see/hear if they were alive at that time, in Lesson #1 Graphic Organizer Students share their observations as scientists of the past of the LA River. Pose the following and ask for student response: 1. What do these pictures tell us about the people who lived on the river thousands of years ago? (RI.3.7) 2. Imagine the differences between what we can hear today compared to what the Tongva might have heard then Tongva lived on the SAME land that we do today. Many Tongva lived in the area that is now downtown Los Angeles. Try to lead students towards the idea of biodiversity: Tongva lived in a habitat that was rich with different types of animals and plants, water sources, landscapes. Human impact has affected biodiversity today (they will see that on the Rover and see it around them on a daily basis). CHUMASH: See note in background reading in this packet on the Chumash who settled on the River before the Tongva. Anthropologist / Archaeologist GUIDED PRACTICE. (_10_ min.) Web of Life – yarn activity 1. Have students sit/stand in a circle. Students have already been introduced to the Tongva (“introduction to new material”). LESSON- CYCLE Option: ask a few students to share a piece of information they remember from the introduction. MATERIALS. L#1 Graphic Organizer Ball of yarn/string Hole-punched biodiversity cards (resource cards may be repeated to suit class size) There are 2 options for biodiversity cards. You can select either. 2. Explain each student is going to represent a resource that lived near the Los Angeles River. Reference vocabulary visual aid/artifact 3. Pass out one biodiversity card to each student. Have each student introduce themselves by reading the front and back of their cards. For larger class size, smaller groups make pace of activity more efficient. Students can be split into two groups or in any way that is appropriate to class needs. 4. Starting with your picture (example: sun), read your description on the back of the card and holding the end of your yarn, toss the ball to a resource you depend on or that depends on you (could be anyone since all forms of life depend on the sun). 5. Explain to students who catch the ball of yarn that they must now toss the ball of yarn to a resource they need or needs them. Have students give an explanation for their choices. 6. Continue until each student is holding a piece of yarn (one person may get tossed to more than once if needed). 7. Point out that they have created a “web of life” that existed in the Los Angeles River thousands of years ago. Elements they represent are all connected to one another in terms of what they needed to survive and what they provided for the survival for others. 8. Reference the vocabulary word on the Class-made visual aid/artifact of L#1 G.O. Ask students and solicit responses. “What if we didn’t have one part of our web? Would we all be affected?” ( SL.3.1) (objective) As a class, discuss: What would happen if there were less water in the River? What would happen to the steelhead trout? Extension: Ask students to identify if they are one of the following: producer, consumer, or decomposer. What is the effect on the Tongva? o Students will be practicing cause and effect on the Rover, L#2. Option: To demonstrate what would happen if we lost one part of the river environment, tug on the yarn. When someone feels a tug then they should tug slightly, until everyone is tugging. Stop the tugging and try another member of the web, asking them to tug on their yarn. Discuss how everyone is connected and affected by each other. INDEPENDENT PRACTICE. (_15_ min.) shorter than usual LESSON- CYCLE Students draw and describe 3 connections from the web of life activity with 2 partners. They can use their own resource in the G.O. (W.3.8) MATERIALS. L#1 G.O. 2 partners with biodiversity cards CLOSING (_5_ min.) MATERIALS. Part I: Instruct students to take out the exit slip (on the back of the formative assessment). Rover Behavior Expectations Contract & mini-quiz on the back (photocopy 2-sided) Students answer questions individually. Collect exit slip paper. Part II: Go over the Rover Behavior Expectations Contract as a class. Ask comprehension questions while going through the contract. Students initial and sign, then take the mini-quiz. Record percentage score of exit slip on the Teacher Feedback form. LESSON- CYCLE Go over answers as a class. Students rate their understanding of behavior expectations. Teacher stamps/marks students who have completed the quiz. Note: All students must complete the contract and quiz- all students are expected to visit the Rover. If school does not have photo releases on file, please download the form from the FoLAR website. Distribute to students. Families may decline.

Timeline of Native People on the River: Chumash and Tongva For more history: See “Watershed Wonders” PDF (starts on pg.5) on the Educator Resources page. It’s really interesting! See excerpt from WS Wonders: Statistics and the Cultural History of the River. On the Tongva, visit KCET Gabrieleno Tongva Mission Indians (audio): Chief Red Blood Anthony Morales recounts the history of the Gabrieleno-Tongva Mission Indians. Circa 38,000 BC Los Angeles has been pulling in visitors for tens of thousands of years, as a future fossil is trapped inside what are now the historical La Brea Tar Pits. Circa 8000 BC Chumash people settle the Los Angeles basin. Circa 500 AD Tongva Indians settle in the Los Angeles basin. Some accounts say they displaced the Chumash. By the 16th century, the region’s main village will be called Yang-Na, near present-day Los Angeles City Hall. 1800s The Spanish and new settlers are diverting some of the water from the Los Angeles River. 1934 More floods came and devastated the foothill communities killing 40 people in the La Crescenta area and costing $100 million in damages. 1935 Congress appropriates $19 million under the Emergency Relief Act for the construction of storm drains and catch basins. 1936 The Flood Control Act of 1936 authorizes $70 million for improvements and changes the role of the U.S. Army Corps of Engineers from providing emergency relief to supervising permanent future flood control plans for the Los Angeles, Rio Hondo and San Gabriel Rivers. 1938 The most damaging flood in the history of Los Angeles struck in 1938 and caused $62 million in damages and 85 people died. Where channelization had been implemented, the engineers were able to see which of their control measures worked and which measures did not. Areas of reinforced concrete had withstood the flood, and so, a plan to increase the amount of channelization was proposed and approved. “Introduction to New Material” section of lesson (See above resources for more content) Thousands of years ago, the Tongva (Gabrieleno) Indians built their villages throughout the Los Angeles basin. They built their villages near the River because of the many resources the River had to offer. They were also aware of the frequent natural flooding of the shallow Los Angeles River and built their villages in the adjacent hillsides. The River had a rich and biologically diverse ecosystem that supported many daily needs such as drinking and bathing not only for the Tongva peoples but it also supported a diversity of animals that depended on the water, fish, birds, and plants growing and living by the River as well. Many plants and trees that grew by the River providing shade for fish, aquatic insects, and places to nest for birds but they also were used by the Tongva as food, medicine, tools, baskets and building materials. This biodiversity of plants, insects, fish, and animals made the River an ideal place to hunt, fish, and gather food and supplies needed for daily life for many life forms. The Tongva had respect for nature and the River and had a symbiotic relationship with their environment in which nothing was wasted. They knew maintaining balance and biodiversity within the environment was needed to survive because all the living things of the River were connected and dependent upon each other to survive, this is called the web of life. The Tongva did not have supermarkets, hospitals, and stores like we have today. Instead, they relied on and used a variety of the plants and animals that lived near the Los Angeles River. Biodiversity Why is biodiversity important? Habitats that have a greater variety of different species of plants and animals have a greater biodiversity. These habitats are also healthier and more stable. How is it more stable? One reason diverse communities have greater levels of health is that organisms of the same species tend to be more spread out. This reduces the ability of a disease to spread throughout a habitat. Additionally, if a certain type of species of tree or plant does become infected, the other species will remain and continue to provide the habitat components for the organisms in that area. The Web of Life What is the web of life? The idea of the web of life is shown by the interdependence within an ecosystem. Animals and plants depend on a complex system of food for survival. In a typical prairie ecosystem, the web might work like this: The sun provides energy for the grass; grasshoppers feed on the grass; birds and frogs eat the grasshoppers; snakes eat birds, frogs and mice; owls and hawks will eat the birds as well as snakes, frogs and mice. When an animal dies, it is decomposed by worms, fungi and bacteria action and nutrients are released to the soil during the decaying process for the grass to use again. Connecting the many plants and animals with lines representing their functions and food chains within this web would create a tangled maze. It is obvious that all forms of life in the ecosystem are dependent on all other living and non-living things for food, nutrients and energy. Habitats, Biomes, and Ecosystems Simplified The Earth has many different environments, varying in temperature, moisture, light, and many other factors. Each of these habitats has distinct life forms living in it, forming complex communities of interdependent organisms. What is a biome? Biomes are ecosystems where several habitats meet. They include the geography and climate conditions of communities of plants, animals, and soil organisms. The Earth itself is one big biome. Smaller biomes include: tundra, tropical rainforest… What is an ecosystem? Ecosystems vary in size and can be as small as a puddle as large as a forest. Any group of living and nonliving things interacting with one another can be considered as an ecosystem. It's the way nature works together, for example, the relationship between ants, anteater, soil, trees, forest and sun. Within each ecosystem, there are habitats. What is a habitat? The word "habitat" is Latin for "it inhabits". A habitat is a place where a environment in which plants, animals, and organisms live. species lives. It is the natural place or Habitats are specific to a population. Each population has its own habitat. If the habitat changes and it no longer works for the species, they adapt or move on. Many species can live in the same habitat, such as a pond. Habitats include different biomes, forestations and ecosystems. The forest ecosystem and its individual components and the environmental factors affecting the ecosystem.
