The adopted 正规买足球的App K – 8 science curriculum is 增强科学. The 增强科学 instructional model allows students to access their prior knowledge to connect past learning experiences to the present and emphasizes the use of evidence-based reasoning for scientific explanations and engineering solutions in order to communicate recommendations to address real world problems. 

Each unit is constructed as a compelling storyline which begins by engaging learners in a puzzling, relevant scientific phenomenon or engineering problem. Learn more about the unit phenomena and storylines for K – 5th grade below.

Below are descriptions of the three units in 2nd grade Amplify curriculum. 

Plant and Animal Relationships: Investigating Systems in a Bengali Forest. What is the connection between chalta fruit, elephants, and droppings? Students find out as they investigate an authentic mystery that occurred in a broadleaf forest habitat in northeastern India. They plan and conduct investigations to figure out what plants need to grow and ways that many plants rely on animals to disperse their seeds. Students use mathematical thinking and concepts of 比例 and quantity to 使 sense of their measurements and other data. They construct scientific explanations about how the parts of the Bengali forest work together as a system.

材料性能:设计胶. Students take on the role of glue engineers and design and test a glue for use at their school. They figure out cause-and-effect relationships related to heating and cooling materials, and find patterns in the properties of substances and mixtures. Students 使 arguments about effective glue recipes using the evidence they have gathered from investigations and science texts.

变化的地貌:消失的悬崖. Students act as geologists helping a recreation center director understand what is happening to a nearby cliff, 哪一点似乎发生了变化. 他们问一些关于地形的问题, 水, 和风力, and use hands-on models to figure out how small-scale changes to landforms can add up to large-scale changes over long periods of time. 因为他们获得了有关侵蚀的信息, they figure out how rock that appears stable in the short-term can actually change a lot over time. 他们创建图表来传达他们的发现.

Below are descriptions of the three units in 3rd grade Amplify curriculum.  

平衡力:调查浮动列车. Scientists and engineers have figured out a way to build a train that actually floats on air as it goes cruising down the track at high speeds. Students work to explain how this train works in order to reassure residents of a town that the train is safe. 学生们想出关于磁力的概念, 重力, and how forces can cause an object’s movement to change or stay stable. They communicate their ideas by making digital and physical models and by writing explanations.

Environments and Survival: Snails, Robots, and Biomimicry. Students play the role of biomimicry engineers studying a population of snails. They analyze data to figure out why some organisms are more likely to survive in their environment. They think about the systems made of organisms and the environment in which the organisms live to understand how the environment affects organisms’ likelihood of survival. Students apply what they learn about the structure and function of animals’ body parts to plan, 使, 以及解决问题的测试设计, such as a robot that can remove and grind up invasive plants.  

Weather and Climate: Establishing an Orangutan Reserve. 气象学家的角色, students investigate weather and climate patterns in order to 使 scientific arguments about where to establish an orangutan reserve. They use mathematical thinking to find patterns in weather data, 考虑规模, 比例, and quantity as they learn to 使 reliable measurements of weather. They also define and work to solve an engineering problem related to natural hazards.

Below are descriptions of the three units in 4th grade Amplify curriculum.

能源转换:在厄格斯敦停电. Students take on the role of systems engineers for Ergstown, 一个经常停电的虚构小镇, and explore reasons why an electrical system may fail. They obtain information from science books and system models to learn about types of energy, 能源, 能量转移, 能量转换. They define engineering problems related to the town’s electrical system and design wind turbines using what they have learned about energy and matter.

地球的特征:沙漠岩石峡谷的奥秘. 地质学家的角色, students investigate a fossil and the geologic history of the area where the fossil was found. Students write scientific arguments about how the fossil formed and what the environment of that area was like in the past.
