Curated OER
Interpreting Data-Working with Controls and Variables
Pupils review the meaning of control and variables, and state difference between dependent and independent variables. They complete a worksheet with the definitions and complete problems that show their understanding.
Curated OER
pH Testing
Students explore the use of variables in the scientific method. They identify the dependent and independent variables through pH testing. Students construct graphs of their data and analyze their findings.
Curated OER
Reaching New Heights
Learners explore the relationship between two variables. Students measure their arm span and height. They gather this class data to design a scatter plot. Learners interpret the meaning of individual coordinates and the overall graph....
Curated OER
Non-Random Variables: NBA Championship
Young scholars demonstrate probability distribution of non-random variables. Students collect data on the NBA Championships. They record the data and compute subsets and permutations.
Curated OER
2 x 2 Linear Systems
Students graph 2x2 systems and solve them algebraically. They investigate parallel systems by solving equations.
Curated OER
Variables
Students watch a video show how to identify the independent variable, dependent variable and controls in an experiment; and design experiments that use controls to isolate a single independent variable and measure the resulting dependent...
Curated OER
Particulate Matter
Students gather air samples using a particulate air monitoring card. They investigate the variable that influence the amount of particles that they collect.
Curated OER
High School Mathematics Problems from Alaska: AL-CAN Highway Problem
High schoolers write and solve equations converting between metric and standard measurement as they travel southeast on the Al-Can Highway.
Curated OER
High School Mathematics Problems from Alaska: Firewood Problem
High schoolers write and solve equations for the cost of firewood by the cord, then use this information to develop tables of values and graph their equations.
Curated OER
Discovering Albedo
Students read a thermometer accurately, collect and record data, and generate a graph based on data. They learn what independent and dependent variables are. They analyze data and make conclusions concerning how soil coverings affect...
