If you live in the San Francisco area and are interested in ants, take a look at this post on my Wild About Ants blog about a citizen science project that’s being run by the California Academy of Sciences. It’s definitely kid friendly.
Yes, we were in San Francisco last week. We got to see a lot of interesting new things.
Let us know if you decide to participate in the ant study. We’d love to hear what you find out.
Have you seen the new California Academy of Sciences building in Golden Gate Park?
It has a space age-looking green roof.
Yes, these are pictures of the actual roof. Any ideas what the gray strips with wire over them are? Here’s a close up:
We were told they are the pathways that allow people to walk through for maintenance or study. The gray rocks are lightweight pumice or lava rock. They could also be for drainage.
Although we saw different types of plants growing on the roof, the most common are perennial strawberries.
Why would anyone want a green roof? We learned that the roof helps moderate the temperature of the building, creates less water run off during rains, and supplies food for wildlife.
Although green roofs have been around for a long time, these roofs are designed with modern materials and are often used on much larger and more complicated building than in the past. If you like the idea of a green roof, here are some ideas for activities:
1. Research green roofs and then design and create your own small green roof model. Two things to consider are the weight of the planting materials (the lighter the better) and how to make sure the bottom layer doesn’t leak. Experiment with different materials and see how long they last.
2. Find out which plants are used on green roofs in your area and try growing some in small containers, such as flats. Experiment with similar plants. See if you can find a type of plant, or mix of plants that grow well in roof conditions. Sedums are often popular green roof plants, but my son is trying the ground cover dichondra on his model green roof.
3. See how a green roof changes the temperature of the building it covers. Compare the temperatures inside a box covered with plants versus one with standard insulation versus an uncovered box. Look at the range of temperatures over time, if possible.
4. Look at how much water runs off a green roof versus a conventional roof during a rain storm. Think about how you would test this and design and experiment. Can you collect the run off?
5. Investigate what kinds of wildlife are attracted to green roofs. The California Academy of Sciences’ roof had a bee hive on it.
We’d love to hear about your green roof projects.

It’s time to start thinking about another citizen science project:Â The Great Sunflower Project at www.greatsunflower.org.
The sunflower project involves growing a specific type of sunflower, Lemon Queen, and recording the types and how many bees come to visit the flowers.
This year the organizers are asking the participants to buy their own seeds because they can not fulfill the orders for the huge number of requests they received last year.
If you are interested in participating, the first step is to go to the website and register. You will find more instructions there and get future newsletters with information and updates.
The sampling protocol has been simplified a bit. This year you and your children will:
1) count the number of flowers on your plant with pollen;
2) record all bees (not just the first 5) your sunflower for 15 minutes; and
3) enter the data online.
Our family participated last year. I have to say I hadn’t had much success growing sunflowers before, but these Lemon Queen variety seeds grew beautifully.
We had quite a few bees visiting, although no honey bees.
Did you participate last year?
Let us know, we’d love to hear from you.
