San Diego Phenomena

Phenomena in Science Education

Phenomena are the natural and man-made observable events that provide context for the work of scientists and engineers. Recent science standards changed the focus from learning about science to figuring out science. Phenomena are a powerful way to engage students and empower them to wonder and investigate.

Sometimes, we look too hard for the phenomenal events and miss the every-day occurrences that are just as intriguing. The list below is a constant work in progress and will be updated as new submissions are received and new occurrences are observed in and around San Diego County.

It snows in some parts of San Diego County but rains in others Image: Caltech Astronomy, Palomar Observatory A winter storm in San Diego might bring several inches of snow to Palomar Mountain but only rain to nearby Valley Center. Why does it rain in some places but snow in other places? It is more likely to snow at higher elevations and rain at lower elevations. Higher elevations are closer to the Sun, so why are higher elevations cooler? Resources Scientific America: If heat rises, why does the temperature decrease at higher elevations? UC Santa Barbara: Why is it colder at a higher altitude when technically it is closer to the sun?

How does location influence the tide timing? Use the NOAA information below to compare data from Scripps Pier in La Jolla and Quivira Basin in Mission Bay.

Ants travel in lines Image: Zachary Hunt, YouTube Spring time in Southern California brings out the ants. When ants swarm that crumb on your kitchen counter, they will likely travel in a straight line to get there. Why do ants move in lines and how do ants known to follow this path? What would happen if we obstructed that path with a solid object?

How can a jet of water lift a person off the ground? Use this animated visual as reference.

Marine fossils found near Normal Heights Image: San Diego Natural History Museum In March 2016, while constructing a bike pathway next to SR-15 between the neighborhoods of Normal Heights and Kensington, surveyors found fossilized whale bones and shells. What questions do you have about this discovery? For example: How did remains of marine life end up on dry land? What does this finding tell us about this area over thousands or millions of years? What can this evidence tell us about Earth's processes over time?

This water is popular for freeway median irrigation use and on farms. How do we recycle sewage water? Isn't all water recycled? Where does our drinking water come from and why is this recycled water not suitable for drinking?

The Forest Service even advertises these fires as controlled burn alerts on their website. One of the justifications is that these controlled burns prevent wildfire. This is a literal example of fighting fire with fire, but how does it work? In 3-ESS3-1, students are asked to make a claim about the merit of a design solution to reduce the impact of a weather-related hazard. How can fire be used to mitigate wildfire? What steps could be taken to reduce the chance of massive wildfires?
