Science Content Area Standards: 1a. Students know objects can be described in terms of the materials they are made of and their physical properties (e.g., color, size, shape, weight, texture, flexibility, attraction to magnets, floating, and sinking). 4b. Describe the common properties of common objects. 4e. Communicate observations orally and through drawings.
English Language Development Standards: 1.A.1. – Exchanging information and ideas with others through oral collaborative conversations on a range of social and academic topics. 1.C.11. – Supporting own opinions and evaluating others’ opinions in speaking and writing.
Common Core State Standards: Text Types and Purposes: 2. Use a combination of drawing, dictating, and writing to compose informative / explanatory texts in which they name what they are writing about and supply some information about the topic. Comprehensions and Collaboration: 3. Ask and answer questions in order to seek help, get information, or clarify something that is not understood.
Objective: Students will be able to make and test predictions about sinking and floating and then classify objects according to whether they sink or float.
Please answer this question on a separate sheet of paper and bring it back to class tomorrow in order to share your answers:
Based on what you have learned about sinking and floating and their relationship to density, what are some objects you would not have thought would be able to float based on their size and weight? And, why are these objects able to float?
