2. Which object has the greatest volume?

3. Explain how the 3 states of matter are different. Write a half page in your journal

4. Will it float Make a prediction about if each object will float or sink, and explain what helped make your decisions. You may touch and feel the objects, but can not put them into the water yet. ObjectPrediction (float or sink) Results Aluminum foil Aluminum foil ball Brass brad Paper clip Wooden cylinder Plastic bead sponge Plastic chip

5. So… what happened? Discuss and journal at your table Where there any surprises? Why did they surprise you? Did all the metals sink/float? Which object had the greatest mass (estimate based on touch) Which object had the least mass? Did mass determine if it would sink or float?

6. Not all about mass -Which object do you think had the largest mass?

7. Not all about mass -Which object do you think had the largest mass? -The wooden cylinder, but it floated -Do objects that are made of the same material act the same (sink of float)

8. Not all about mass, shape, size or material -Which object do you think had the largest mass? -The wooden cylinder, but it floated -Do objects that are made of the same material act the same (sink of float) -The metal paper clips and brad sank, the metal foil, and foil ball floated, so its not about shape either -The plastic bead floated and the plastic chip sank…

9. Relative density Its really about a combination of things, but mostly the mass and volume relationship. Density = mass/volume Water = 1g/ml = 1.0 Relative Density: Density of an object compared to water Greater density = sink Less density = float

10. Results Greater relative density (sink) Less relative density (float)

11. Not just solids Just like solids, some liquids float on water, while others sink

12. Insulator vs. conductor Conductor -allows energy to flow Heat, electricity, or sound – Think of music conductor – How do we use these in every day life Insulator - keeps energy from flowing Heat, electricity or sound -how do we use these in every day life

13. Insulator or conductor - compare how cold the ice water feels in the different containers/barriers to determine if they are an insulator or conductor Aluminum foil Paper towels Cotton Metal beaker Plastic beaker

14. Results Insulator – Noticeably less cold Conductor – Still cold.. burr

15. Homework Vocabulary foldable (outside = word, inside flap= definition, backing different for each word) Matter - on the backing a non example Solid – example Liquid – example Gas – example Mass – picture of what we use to measure it Volume – picture of what we use to measure it
