Science- Matter: Properties and Change
Transcript of Science- Matter: Properties and Change
2.P.2 Understand properties of solids and liquids and the changes they undergo. 2.P.2.1 Give examples of matter that change from a solid to a liquid and from a liquid to a solid by heating and cooling. 2.P.2.2 Compare the amount (volume and weight) of water in a container before and after freezing.
2.P.2.3 Compare what happens to water left in an open container over time as to water left in a closed container. Liquids Liquid or Solid? Which objects will roll the best? Milk Liquid Candy Solid Ball Solid Rock Solid Glue Liquid Metal Washers Solid Water liquid Wooden Block solid What's the Rule? Things that are... yellow! What's the Rule? What's the property? Color What's the property? Shape What's the property? What's the Rule? Things that are... made of metal. Metals can be magnetic. The Flow of Things Viscosity An experiment to test viscosity (flow) Properties: Color Shape Hardness
& Softness Buoyancy
Float & Sink Magnetism Stacking
& Rolling Hard Soft Properties: Do not have their own shape. They take the shape of their container. Opacity & Transparency color Viscosity & Fluidity buoyancy miscibility Opaque- does not allow
light to pass through Transparent- allows light to pass through Fluid-
flow Viscose- decreased or "slow" flow Dense liquids sink to the bottom how liquids mix Properties Objects can be grouped by their properties- such as: size, shape, color, texture... Predictions: Scientists make predictions before they begin an experiment. This is not just a guess... it is an educated guess!
You tell what you think will happen based on the facts you know! My prediction: I think the ball will roll better than the block. I predict this because the ball is round. Things that are... square Float or Sink? Metal Washers Foam Blocks Beach Ball Rock Sink Float Float Sink
