Making Sustainable Business Decisions In Four Different Industries and Their Effect on People (Social), Planet (Environment), and Profit (Economics) part of SISL:Activities
The student will gain a better understanding of "Global Warming" and the "Triple Bottom Line" by viewing the first two videos. Further the CEO2 game will introduce many new ideas/options that specific industries have to select from in achieving their desired corporate/company goals.

Choosing Between Home Appliances: Benefits to the Planet and Your Wallet part of SISL:2012 Sustainability in Math Workshop:Activities
Students research various options for new appliances and make purchasing decisions based not merely on purchase price, but also on energy efficiency, which has implications for the planet AND for longer-term personal finances. Students calculate the "payback period" for the more energy efficient appliance and calculate long-term savings.

Economics of installing Solar PV panels: is it worth it to the individual? part of SISL:2012 Sustainability in Math Workshop:Activities
We show that it is economical for an individual to install solar photovoltaic panels in Denver, Colorado; and this is a sustainable strategy for society at large.

Modeling: (1) Revenue Neutral Carbon Taxes; (2) Accelerated atmospheric C02 concentrations part of SISL:2012 Sustainability in Math Workshop:Activities
Design a revenue neutral carbon tax and a plan for implementation; together with a model for what happens if we do not institute such a tax-system.

Water conservation part of SISL:2012 Sustainability in Math Workshop:Activities
Small amounts of water in one home dripping from a faucet can add up to huge monetary and resource losses

Observing different scenarios of climate change using climate challenge web game part of SISL:Activities
Use the web game Climate Challenge by the British Broadcasting Corporation to observe how decision by government can contribute to climate change. By seeing the consequence of government inaction in an interactive web experience, students will be more engaged citizens and voters. To show students that we live in a world with finite resources.
