Every science lesson should include a process skills standard AND a content standard. Additionally, investigations should be conducted to practice multiple process skills EACH nine weeks.

### Process Skills Standards

The student will demonstrate an understanding of scientific reasoning, logic and the nature of science by planning and conducting investigations in which

PS.1 a) chemicals and equipment are used safely;

PS.1 b) length, mass, volume, density, temperature, weight, and force are accurately measured;

PS.1 c) conversions are made among metric units, applying appropriate prefixes;

PS.1 d) triple beam and electronic balances, thermometers, metric rulers, graduated cylinders, probeware, and spring scales are used to gather data;

PS.1 e) numbers are expressed in scientific notation where appropriate;

PS.1 f) independent and dependent variables, constants, controls, and repeated trials are identified;

PS.1 g) data tables showing the independent and dependent variables, derived quantities, and the number of trials are constructed and interpreted;

PS.1 h) data tables for descriptive statistics showing specific measures of central tendency, the range of the data set, and the number of repeated trials are constructed and interpreted;

PS.1 i) frequency distributions, scatterplots, line plots, and histograms are constructed and interpreted;

PS.1 j) valid conclusions are made after analyzing data;

PS.1 k) research methods are used to investigate practical problems and questions;

PS.1 l) experimental results are presented in appropriate written form;

PS.1 m) models and simulations are constructed and used to illustrate and explain phenomena; and

PS.1 n) current applications of physical science concepts are used.
