This site describes how and when 100-year floods occur. It states that flood designations are based on statistical averages, not on the number of years between big floods. It also suggests that it would make more sense to refer to 100-year floods as 1-in-100 chance floods. This resource is a United States Geological Survey (USGS) Fact Sheet. It can be used in teaching quantitative skills.

Os painéis elaborados e disponibilizados para implantação no geossítio Vila Pedra, são produtos geodidáticos de geoeducação a serem utilizados por professores e alunos de ensino básico do município de Irituia e visitantes do local. Eles contêm informações e interpretações geocientíficas e de curiosidades presentes na formação geológica do geossítio, em uma linguagem acessível, dando suporte a sua utilização como espaço de ensino não formal e à visitação turística mais interessante e de forma sustentável, contribuindo para a divulgação e valorização do geossítio.

First we need to make sure we understand exactly what happens in the split & average steps.

Find out how we can make curved lines using straight ones using the string art construction.

What happens if the director changes their mind and asks for two headed robots?

First we'll review weighted averages of two points and extend the idea to three points. Practice weighted averages of two points in Environment Modeling if you haven't seen it before.

How can we calculate a weighted average between two points? (pssst. This video is super important).
