3 Critical thinking skills are used in the solution of mathematical problems.
M3.1 Explore and solve problems generated from school, home, and community situations, using concrete objects or manipulative materials when possible.
M3.1a Use appropriate scientific tools, such as metric rulers, spring scale, pan balance, graph paper, thermometers [Fahrenheit and Celsius], graduated cylinder to solve problems about the natural world
2 Beyond the use of reasoning and consensus, scientific inquiry involves the testing of proposed explanations involving the use of conventional techniques and procedures and usually requiring considerable ingenuity.
S2.1 Develop written plans for exploring phenomena or for evaluating explanations guided by questions or proposed explanations they have helped formulate.
S2.1a Indicate materials to be used and steps to follow to conduct the investigation and describe how data will be recorded (journal, dates and times, etc.)
S2.2 Share their research plans with others and revise them based on their suggestions.
S2.2a Explain the steps of a plan to others, actively listening to their suggestions for possible modification of the plan, seeking clarification and understanding of the suggestions and modifying the plan where appropriate
S2.3 Carry out their plans for exploring phenomena through direct observation and through the use of simple instruments that permit measurement of quantities, such as length, mass, volume, temperature, and time.
S2.3a Use appropriate "inquiry and process skills" to collect data
S3.3 Share their findings with others and actively seek their interpretations and ideas.
S3.3a Explain their findings to others, and actively listen to suggestions for possible interpretations and ideas
S3.4 Adjust their explanations and understandings of objects and events based on their findings and new ideas.
S3.4a State, orally and in writing, any inferences or generalizations indicated by the data, with appropriate modifications of their original prediction/ explanation
S3.4b State, orally and in writing, any new questions that arise from their investigation
1 Engineering design is an iterative process involving modeling and optimization (finding the best solution within given constraints); this process is used to develop technological solutions to problems within given constraints.
T1.1 Describe objects, imaginary or real, that might be modeled or made differently and suggest ways in which the objects can be changed, fixed, or improved.
T1.1a Identify a simple/ common object which might be improved and state the purpose of the improvement
T1.1b Identify features of an object that help or hinder the performance of the object
T1.1c Suggest ways the object can be made differently, fixed, or improved within given constraints
T1.2 Investigate prior solutions and ideas from books, magazines, family, friends, neighbors, and community members.
T1.2a Identify appropriate questions to ask about the design of an object
T1.2b Identify the appropriate resources to use to find out about the design of an object
T1.2c Describe prior designs of the object
T1.3 Generate ideas for possible solutions, individually and through group activity; apply age-appropriate mathematics and science skills; evaluate the ideas and deter- mine the best solution; and explain reasons for the choices.
T1.3a List possible solutions, applying age-appropriate math and science skills
T1.3b Develop and apply criteria to evaluate possible solutions
T1.3c Select a solution consistent with given constraints and explain why it was chosen
T1.4 Plan and build, under supervision, a model of the solution, using familiar materials, processes, and hand tools.
T1.4a Create a grade-appropriate graphic or plan listing all materials needed, showing sizes of parts, indicating how things will fit together, and detailing steps for assembly
T1.4b Build a model of the object, modifying the plan as necessary
T1.5 Discuss how best to test the solution; perform the test under teacher supervision; record and portray results through numerical and graphic means; discuss orally why things worked or didn't work; and summarize results in writing, suggesting ways to make the solution better.
T1.5a Determine a way to test the finished solution or model
T1.5b Perform the test and record the results, numerically and/ or graphically
T1.5c Analyze results and suggest how to improve the solution or model, using oral, graphic, or written formats
