In the app: https://ai.page/roadmap/tn-sci-grade-2 Part of: [Tennessee: Science](https://ai.page/roadmap/tn-sci.md) Goal: Tennessee academic standards: Science, Grade 2 ## 1. Links Among Engineering, Technology, Science, and Society - [Recording Data](https://ai.page/c/recording-data/index.md): Gather and record data using simple methods such as tables, tally charts, and drawings to help answer questions ## 2. Engineering Design - [Modelling with Sketches](https://ai.page/c/modelling-with-sketches/index.md): Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem - [Comparing Design Solutions](https://ai.page/c/comparing-design-solutions/index.md): Analyse data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of each design - [Simple Design Problems](https://ai.page/c/simple-design-problems/index.md): Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost ## 3. Earth's Systems - [Shapes of land and water](https://ai.page/c/shapes-of-land-and-water/index.md): Develop a model to represent the shapes and kinds of land (mountains, valleys, plains) and bodies of water (rivers, lakes, oceans) in an area - [Where water is found on Earth](https://ai.page/c/where-water-is-found-on-earth/index.md): Identify where water is found on Earth and understand that water can exist as solid (ice) or liquid, recognising water in oceans, rivers, glaciers, and underground - [Preventing Erosion](https://ai.page/c/preventing-erosion/index.md): Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land ## 4. Earth's Place in the Universe - [Fast & Slow Earth Changes](https://ai.page/c/fast-and-slow-earth-changes/index.md): Understand that Earth's surface changes: some changes are quick (eruptions, earthquakes) and some are slow (wind, water wearing away rock) ## 5. Heredity: Inheritance and Variation of Traits - [Inherited characteristics](https://ai.page/c/inherited-characteristics/index.md): Analyse and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms ## 6. Ecosystems: Interactions, Energy, and Dynamics - [Changing Environments](https://ai.page/c/changing-environments/index.md): Recognise that environments can change and that this can sometimes pose dangers and challenges to living things - [Plants and animals in their habitats](https://ai.page/c/plants-and-animals-in-their-habitats/index.md): Use a model to represent the relationship between the needs of different plants and animals and the places they live, connecting organism needs to habitat features - [How animals adapt to environments](https://ai.page/c/how-animals-adapt-to-environments/index.md): Identify how animals and plants are adapted to suit their environment and understand that adaptation may lead to evolution over time ## 7. From Molecules to Organisms: Structures and Processes - [Animal Classification Vocabulary](https://ai.page/c/animal-classification-vocabulary/index.md): Use vocabulary for classifying animals and describing life cycles — vertebrate, invertebrate, mammal, bird, reptile, amphibian, fish, insect, arachnid, larva, pupa, metamorphosis, gestation, offspring, complete metamorphosis, incomplete metamorphosis — and apply these correctly when sorting and comparing organisms - [Life Cycles of Organisms](https://ai.page/c/life-cycles-of-organisms/index.md): Develop models to describe that organisms have unique and diverse life cycles but all share the common stages of birth, growth, reproduction, and death - [Animal Body Groups](https://ai.page/c/animal-body-groups/index.md): Describe and compare the external body structure of common animals across groups (fish, amphibians, reptiles, birds, mammals) - [Senses, Brain & Responses](https://ai.page/c/senses-brain-and-responses/index.md): Use a model to describe that animals receive information through their senses, process it in their brain, and respond in different ways ## 8. Waves and Their Applications in Technologies for Information Transfer - [Waves & How They Move](https://ai.page/c/waves-and-how-they-move/index.md): Develop a model of waves to describe patterns in terms of amplitude and wavelength, and understand that waves can cause objects to move - [Communication with Light & Sound](https://ai.page/c/communication-with-light-and-sound/index.md): Design and build a device that uses light or sound to solve the problem of communicating over a distance - [Vibrations & Sound](https://ai.page/c/vibrations-and-sound/index.md): Understand that vibrating materials can make sound, and that sound can make materials vibrate ## 9. Energy - [Friction & Surfaces](https://ai.page/c/friction-and-surfaces/index.md): Compare how things move on different surfaces, noticing that some surfaces create more friction than others - [What happens when things collide](https://ai.page/c/what-happens-when-things-collide/index.md): Ask questions and predict outcomes about the changes in energy that occur when objects collide ## 10. Motion and Stability: Forces and Interactions - [Pushes & Pulls](https://ai.page/c/pushes-and-pulls/index.md): Understand that pushes and pulls are forces that can change the speed or direction of an object's motion, and compare the effects of different strengths and directions ## Health: 0 of 100 Of its 22 own concepts: 0 have an explanation, 0 have practice, 0 have a measurement question, 0 have a checked version.
