Module Anchor Phenomena—K–2

Module Anchor Phenomena—K–2

Phenomena supply students with a strong foundation to fully engage with their learning by offering them exciting and tangible examples of science in the real world. Phenomena also provide the chance for student inquiry—allowing them to ask questions as they observe each phenomenon and take on the role of scientists! This inspires them to discover more about the world around them and develop a lifelong love for STEM. We’ve put together some of the Anchor Phenomena your students will encounter in Twig Science for K–2—plus some fun facts that might surprise you.

Grade 1, Module 1: My Big Nature Adventure

Module Anchor Phenomenon: The thistle plants look alike, but not exactly the same. How are all plants alike and how are they different?

Did you know? Thistles are a group of rather spiky plants with a bad reputation for being unruly weeds. You might already know that the thistle is the national flower of Scotland, but different varieties can be found across Europe and Asia, boasting a range of uses from medicinal properties to a delicious tea. In the Beira region of Portugal, for example, thistles are used to make the famous “Serra da Estrela” cheese!

Grade 1, Module 2: Animal Reporters

Module Anchor Phenomenon: A young elephant makes a sound. Then an adult elephant feeds it. How do animals use their body parts, communicate with their young, and make sounds?

Did you know? Did you know that elephants can communicate at a frequency below the range of human hearing? This type of sound wave is known as an “infrasound” and can reach up to 10 km without being reflected or absorbed by the environment it travels through. Elephants are particularly social animals and will communicate over long distances just to reinforce their bonds with other elephants, as well as to warn one another of danger, or to attract mates. Their excellent hearing isn’t limited to infrasounds, though—they can also hear thunderstorms approaching from several kilometers away!

Grade 1, Module 3: Shadow Town

Module Anchor Phenomenon: During the fall, even in the daytime, the town of Rjukan is in the dark. Why is the town of Rjukan in a shadow?

Did you know? You might dread the gloomy evenings that winter brings or even hate when summer sunrises wake you up too early in the morning, but how would you feel about the sun not setting for weeks on end? Or endless months of darkness? Well, for people that live in the Arctic Circle, that’s how life is! Here, residents have as many as 76 days of sunlight, where the sun never sets. The name of this natural phenomenon is a “midnight sun.” Conversely, their winters last from November to January, when the sun doesn’t rise at all—known as a polar night.

Grade 1, Module 4: Patterns in the Sky

Module Anchor Phenomenon: Child A can only see the Sun out of their window in the morning. Child B can only see the Sun out of their window in the afternoon. What patterns do we observe in the sky?

Did you know? The Sun is by far the biggest object in the Solar System, but the truth is, it’s pretty small compared to other stars in our galaxy. Antares, for example, is 530 times bigger than the Sun, while Mu Cephi, also known as Herschel’s Garnet Star, is more than 1,500 times bigger! The Sun does look small from all the way down here on Earth, but that’s because it’s more than 150 million kilometers from us.

Grade 2, Module 1: My Journey West

Module Anchor Phenomenon: We can use models to help us find Ruthie’s new home in the San Francisco Bay Area. How can we understand and describe the land and water on Earth?

Did you know? San Francisco has quite a unique status as both maritime and mountainous, with the steep and rolling hills that comprise its streets actually being part of the foothills of Montara Mountain. The unusual landscape was created by geological activities thousands of years ago, when the tectonic plates in the ground collided—the Pacific and North American plates. This, in part, is why San Francisco belongs to the Pacific mountain System, which stretches all the way from Alaska to Mexico!

Grade 2, Module 2: Master of Materials

Module Anchor Phenomenon: A spaghetti tower can stand up and hold weight until it is put in hot water. How can we describe materials as different from one another and understand how their properties relate to their use?

Did you know? Pasta and noodles are staples in most people’s homes, and you probably don’t think twice about breaking spaghetti strands before boiling them. But to the “longest noodle” world record winners, that would be unthinkable. In 2017, a Chinese company successfully made—and cooked without breaking—the world’s longest noodle at over 3,000 meters long!

Grade 2, Module 3: Save the Island

Module Anchor Phenomenon: Tangier Island has changed shape over time. How do natural processes shape the Earth?

Did you know? How would you feel if you knew that your home would one day be lost to rising seawater? Tangier Island, located in the Chesapeake Bay between the states of Virginia and Maryland, is home to around 700 people—but in the next 50 years, scientists predict that most of the landmass will be lost. The landmass has already been reduced by 67% since 1850! But for now, the small island is still alive and thriving, and is famous for its delicious crabs and oysters.

Grade 2, Module 4: A Garden for Life

Module Anchor Phenomenon: In this garden, bees are more likely to visit some flowers and butterflies are more likely to visit other flowers. How do living things in an environment depend on one another and what do they need to grow?

Did you know? Did you know that a flower’s color and markings have a purpose? They actually attract different pollinators! For example, bright blue and violet flowers attract bees; red and bright pink colors are inviting to hummingbirds; and butterflies love the warmer, brighter colors such as yellow, orange, and red! And the shape matters too; for example, flowers with flat petals are perfect for butterflies that need somewhere to sit.

Grade 2, Module 2: Marble Run Engineer

Module Anchor Phenomenon: The Dragon Ride can be moved without a person touching it. How are objects affected by the forces of push and pull?

Did you know? Can you guess where the world’s first roller coaster opened? You might have said Coney Island, but it was actually in Paris! The “Promenades-Aériennes” or “Aerial Walk” was unveiled more than 200 years ago, and comprised nothing more than a set of stairs, a small cart with wheels and a bench, and 600 ft of track. This roller coaster was essentially one long ramp, shaped like a heart for optimal speed and efficiency. Built in 1817, the roller coaster opened long before electrification and relied entirely on gravity to reach the top speed of 40 miles per hour!
