Writing to Learn… “Writing helps students get more actively engaged in subject matter, understand information and concepts more deeply, make connections and raise questions more fluently, remember ideas longer, and apply learning in new situations….Reading helps us take in knowledge; with writing, we make it our own.” Daniels, Harvey, Nancy Steineke and Steven Zemelman Content Area Writing: Every Teacher’s Guide.

Focus Question What materials are magnetic?

Explore how magnets interact with materials. 1.Predict: sort objects into two groups (those that will stick to a magnet and those those that won’t.) 2.Test your predictions with the magnet. Prediction

Drawings Charts & Tables Graphs Pictures Component 2: Data Acquisition & Organization

Data Acquisition What materials are magnetic? Magnetic (stick) Not Magnetic (don’t stick)

Claims & Evidence Frames & Prompts Conclusions I Wonder Questions Component 3: Making Sense of Data

Review your list. What do you notice? What can you infer about what materials are magnetic? What evidence do you have?

Claims and Evidence 1. Think about the Focus Question: What materials are magnetic? 2. What do you claim to be true? 3. How can you prove what you are stating from your data organizer? claimsevidence Use your data to make a claim Support your claim with evidence

Conclusion What materials are magnetic? I think that objects that have iron or steel are magnetic.

What materials are magnetic? Iron is the most common metal that sticks to a magnet. Iron is mixed with other metals to make steel.

Other magnetic materials

Dysprosium Gadolinium

Iron Nickel Cobalt Dysprosium Gadolinium Elements with magnetic properties are called materials. Elements with magnetic properties are called ferromagnetic materials. Ferromagnetism

Iron, Nickel, and Cobalt S N S N S N S N S N All the atomic magnets line up and produce a macroscopic magnetic field. This occurs in small regions called domains. Ferromagnetism

“Writing provides a status of our thoughts and forces us to grapple with what we know and what we don’t know.” Santa and Havens (1991) “If you cannot– in the long run –tell someone what you have been doing, your doing has been worthless.” Nobel Laureate Edwin Schrodinger (1951)
