Seed of the Week: Date Palm

We didn’t get any guesses last week for the mystery seed. I was hoping that someone would bite into a sweet, dried fruit, pull out the seed and say, “Aha! The mystery seed was a date seed!”

There are a lot of palm trees growing in the Phoenix metropolitan area of Arizona. One of my favorites is the date palm.

They have a lovely shape.

Although Phoenix dactylifera is the scientific name, date palms are probably originally from northern Africa.

There are a number of different cultivars of date palms. The fruit vary somewhat in shape, size, and of course, flavor.

The book, A Seed is Sleepy, by Dianna Hutts Aston and Sylvia Long, tells about a scientist finding a seed of an extinct date palm that was thousands of years old. When the scientist planted the seed, it grew!

See if you can find a date seed and plant it (just make sure it hasn’t been cooked). Let me know if you grow one.

Globe Astronomy Home Science Project

What fun, another science at home project. This one is called GLOBE at Night, and investigates the amount of light pollution around the globe. All you need to do is locate the constellation Orion and record what you see. Measurements are to be taken between March 3 -March 16, 2010. Go to the website for instructions and information packets.

Even if you don’t want to participate, check out the way the constellation Orion appears to us under different “magnitudes.” According to the site, magnitude is how astronomers describe the brightness of an object.

While you are at it, compare what you see to this view of Orion from the Hubble Telescope (Image from NASA Images).

What magnitude is the view in your area?

The Great Sunflower Project and Bees

It’s time to start thinking about another citizen science project:  The Great Sunflower Project at www.greatsunflower.org.

Seed-packet-front-Great-SunflowerThe 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.
