Claim-Evidence-Reasoning in Science

Claim-Evidence-Reasoning in Science

This week in Science we moved into looking at natural hazards, and everyone is excited to share what they know about earthquakes, volcanoes, hurricanes, etc and all the damage they inflict. Over the next weeks we will definitely increase our knowledge about how these geologic threats significantly alter human populations, activities, buildings, and land and we will explore the fact that humans cannot eliminate natural hazards but can take steps to reduce their impact.

However, underlying this exploration of natural hazards will also be some very important work around the practice of making a claim about an issue or about the merits of a solution, and backing that claim up with evidence (from observations, data, or texts) and also with clear reasoning....

Stepping into Science

Stepping into Science

Our first science unit will traverse some interesting terrain, as we will be investigating a series of questions related to using our resources wisely. Along the way, we will meet interesting scientists (including kids who have made meaningful contributions) and talk about how scientists think and interact with the world. We'll discuss energy, renewable v. non-renewable resources, Earth's systems, our impact on the Earth's systems, and we'll work through a design challenge in which we design windmills that can lift pennies. The design challenge process will introduce us to prototyping and iterating -- ideas that we will revisit often....
