LEAF 2015 - The Movie!

Enjoy Natalia's movie documenting our ten days of exploring and working in the field.

Preparing for Makers' Day Projects - Global Buckets = Watershed Model!

Here is the movie that inspired the watershed model project. Be sure to saturate the dirt in your bucket from the top and then fill the bottom bucket through the pvc pipe every two weeks. Use a nitrogen rich fertilizer once a month.

Young LEAFers Strive to Make Sense of the Principles of Ecology

The five facts of life are:

- Diversity assures resilience
- Is what makes up the web of life
- One species’ leftovers are another species’ snack
- Life is created by networking
- Most energy comes from the sun

I saw the five facts of life when we were learning about natures FBI’s and how a dead salmon gives nutrients to an alive salmon and when we were taught about how microbes eat waste in sewers, which become cleaner sewage water, and so on. At Herons Head Park we learned about solar energy and many different ways to powers your home using nature.

People can use the five facts of life in their everyday lives by recycling, using natural sources of energy, solar power and composting. One could also help by donating elements of their bodies, such as blood or hair, to someone who really needs that material.

The last two days of LEAF have been a blast! On Thursday, we went to SPAWN which was probably my favorite thing we've done so far. I thought it was great that kids got to teach other kids, instead of the usual adults teaching kids. I also had fun weeding and just exploring the place as we walked around.

After that we went to the store to buy ingredients for food. That was also lots of fun, but hard trying to find all of the right ingredients.

On Friday, we went to Heron’s Head Park. It was awesome when we got to see the only 100% off the grid building in San Francisco. I found how it worked with all the solar panels and other things very interesting. After we were finished in Heron’s Head Park, we went to the sewers. That was probably the most disgusting and coolest thing in my entire life.

Diversity assures resilience. Species that adapt to their surroundings are more likely to survive.

Matter cycles through the web of life continuously. As an example, death and decay of one creature becomes food for another creature.

One animal’s waste is another animal’s food. Waste starts a new cycle of life.  For example, cow poop gets eaten by dung beetles.
The sun provides energy to all things. All living things ultimately depend on the energy provided by the sun.

Life took over the earth not by combat but by networking. All life is in one way or another, dependent on other life.

I saw the facts during the “Each one - Teach One” lessons where each of us became experts on some small part of the ecosystem and went on to teach a friend everything we know .

People could use the five facts of life in a roof top garden to make a small urban insect paradise.

1. Objects repeat themselves over and over through living things.
2. Sun gives energy to most things on Earth.
3. Having different things in your body makes you stronger.
4. Deer droppings are food for worms which create dirt which is good for the Earth
5. Life did not battle for the planet, they worked together for the planet.

I saw most of the energy comes from the sun at Herons Head Park when they were using solar panels. I sort of saw one species waste is another species food at the sewer treatment plant when the water is clean enough it is turned into water again. at SPAWN I saw diversity assures resilience when we were pulling weeds because we were all weeding our own way. I saw matter continues itself throughout the web of life when we were at SFPUC because our waste continues it self throughout our life. I saw life did not take over the planet by combat but by networking when we were at Heron's Head Park when they turned it from a dump into a park.

Someone could use another species waste is another species food when the humans waste get cycled into other peoples water. They could also use the sun powers most of the planet by using solar panels. They could use objects repeat themselves over and over through living things by eating and it goes throughout heir body, out their body and cycles back through to their body again. They did life did not take over the planet by combat but by working together when the humans came to life. They have diversity assures resilience by being better at different things.
