LIFE SCIENCE CONCEPTS (Habitats) | identify how climate or other environmental change (volcanic/tectonic/fire/pollution) can alter a local habitat and predict what effects this will have on the plants, creatures, and people living in this habitat | 19. Earth in Action: PebbleGo (Login to PebbleGo, click “Earth Science”, “Earth in Action” and “Avalanches, Floods or Tsunamis”) | Examine effects of different amounts of available water, light, nutrients, pollution and/or space on plant life. Predict related changes a given habitat might experience with too little or too much water, sunlight or nutrients |
LIFE SCIENCE CONCEPTS (Habitats) | create and apply functional sorting to classify natural objects using observable physical characteristics | 20. Characteristics of Materials: BBC Landforms: PebbleGo (Login to PebbleGo, click “Earth Science” and “Landforms”) | Using observable similarities and differences, sort leaves, shells, coins, books and/or other classroom accessible objects into morphological groupings of relatedness. Students present their classification schema and explain the sorting criteria they used |
LIFE SCIENCE CONCEPTS (Habitats) | identify a variety of non-living objects readily available in the classroom and sort them into identifiable categories | 21. Variation: BBC | |
PHYSICAL SCIENCE CONCEPTS (Sound) | explore pitch by changing the rate of vibration with a variety of objects | 1.Changing Sound: BBC | 1. Create and manipulate wave patterns using a variety of materials (string, slinky, water surface, tuning forks) 2. Design a musical instrument based on vibrations 3. Observe a Native American drum presentation and then interview a drum player/maker 4. Demonstrate how drum shape and materials integrate science concepts of vibration and sound waves |
PHYSICAL SCIENCE CONCEPTS (Sound) | examine relative conductivity of sound waves using a variety of materials and sort accordingly | 2. Sound and Hearing: BBC | 1. Conduct sound energy to physical objects by creating visible or audible waves in a variety of materials. Sort materials into groupings by relative conductivity |
PHYSICAL SCIENCE CONCEPTS (Force and Motion) | investigate the relationship between motion and energy | 3. Pushes and Pulls: BBC | 1. Explore different ways to move a ping pong ball from one location to another 2. Experiment with launch distances of rubber bands when stretched to different lengths |
PHYSICAL SCIENCE CONCEPTS (Force and Motion) | explore magnetism as a force | 4. Magnets and Springs: BBC | Classify objects by whether they are attracted to a magnet or not |
PHYSICAL SCIENCE CONCEPTS (Force and Motion) | explore gravity as a force | 5. Forces and Movement: BBC | Use measurements to demonstrate that heavier objects require more force than lighter ones to overcome gravity |
EARTH AND SPACE CONCEPT (Earth’s Orbit and Tilt) | name and describe the seasons | 1. One year in two minutes: Neok12 2. Weather: PebbleGo (Login to PebbleGo, click “Earth Science”, “Weather” and “Fall, Winter, Spring or Summer”) | Compare and contrast Alaska’s seasons to those in other environments |
