0 of 14 concepts ready to learn · Markdown, for your AI

1. Engineering Design · Optimizing the Solution Process

1. Comparing Design Solutions: Analyse data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of each design

2. Engineering Design · Developing Possible Solutions

1. Modelling with Sketches: 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

3. Engineering Design · Defining and Delimiting Engineering Problems

1. Simple Design Problems: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost

4. Earth's Systems · The Role of Water in Earth's Surface Processes

1. Where water is found on Earth: 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

5. Earth's Systems · Plate Tectonics and Large-Scale Systems

1. Shapes of land and water: Develop a model to represent the shapes and kinds of land (mountains, valleys, plains) and bodies of water (rivers, lakes, oceans) in an area

6. Earth's Systems · Earth Materials and Systems

1. Preventing Erosion: Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land

7. Earth's Place in the Universe · The History of Planet Earth

1. Rapid earth changes: Use information from several sources to provide evidence that Earth events can occur quickly (earthquakes, volcanic eruptions) or slowly (erosion, mountain building)

8. Ecosystems: Interactions, Energy, and Dynamics · Interdependent Relationships in Ecosystems

1. Plants and animals in their habitats: 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
2. Ocean Ecosystems: Understand ocean ecosystems as interconnected systems where living things (producers, consumers, decomposers) and non-living factors (temperature, salinity, light, currents) all interact, and that changes to one part affect the whole system

9. Waves and Their Applications in technologies for Information Transfer · Wave Properties

1. Volume & Vibrations: Find patterns between the volume of a sound and the strength of the vibrations that produced it

10. Motion and Stability: Forces and Interactions · Forces and Motion

1. Balanced & Unbalanced Forces: Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object

11. Matter and Its Interactions · Structure and Properties of Matter

1. Testing Materials for Uses: Give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials including metals, wood, and plastic
2. Classifying Materials: Plan and conduct an investigation to classify different kinds of materials by their observable properties
3. Choosing the Right Material: Identify and compare the suitability of everyday materials for particular uses, explaining why specific materials are chosen for specific purposes
