Learners determine the equilibrium constant for a chemical system and use graphing techniques and data analysis to evaluate experimental data.
Curated OER
Locating the Salt Front
Students use Hudson River salinity data to create a line
graph that shows the location of the salt front, and use math
skills to explore how this location varies over time. They use the graph to estimate the location of the salt front...
Curated OER
Let it Grow and See What Happens
Pupils participate in an experiment in which they try to stop algae from growing. In groups, they develop a hypothesis and test it while making changes to the experiment along the way. They make observations and organize their data to...
