Science: Grade 7 : Standard 2 Scientific Thinking Students use instruments and tools to measure, calculate, and organize data. They frame arguments in quantitative terms when possible. They question claims and understand that findings may be interpreted in more than one acceptable way. Computation and Estimation 7.2.1 Find what percentage one number is of another and figure any percentage of any number. 7.2.2 Use formulas to calculate the circumferences and areas of rectangles, triangles, and circles, and the volumes of rectangular solids. 7.2.3 Decide what degree of precision is adequate, based on the degree of precision of the original data, and round off the result of calculator operations to significant figures that reasonably reflect those of the inputs. 7.2.4 Express numbers like 100, 1,000, and 1,000,000 as powers of 10. 7.2.5 Estimate probabilities of outcomes in familiar situations, on the basis of history or the number of possible outcomes. Manipulation and Observation 7.2.6 Read analog and digital meters on instruments used to make direct measurements of length, volume, weight, elapsed time, rates, or temperatures, and choose appropriate units. Communication Skills 7.2.7 Incorporate circle charts, bar and line graphs, diagrams, scatterplots, and symbols into writing, such as lab or research reports, to serve as evidence for claims and/or conclusions. Critical Response Skills 7.2.8 Question claims based on vague attributes, such as ÒLeading doctors say...,Ó or on statements made by celebrities or others outside the area of their particular expertise. |
