California and Colorado
Olive who? Olive you! And you’ll love learning about these two states today! Back to the front of the alphabet as we learn about California’s olives and Colorado’s proso millet with these fun activities!
Colorado is ranked #1 in the nation for production of proso millet! Proso millet is an annual grass grown as a grain crop and used for bird food, pet food, and even livestock feed. It can even be ground down to be used as a flour substitute when cooking! This grass originates from Eastern Europe and was brought to the U.S. by early English settlers! Today, Colorado grows around 6.4 million bushels each year!
Today you will meet two characters who are an unlikely match! Follow along on their adventure with today’s read aloud “Max and Bird” by Ed Vere.
Since proso millet is used in bird feed, your activity today is to see what bird feed, and the seeds in the feed, birds in your area prefer! Fill up two containers (or bird feeders) with different types of bird feed. Set them outside about 6 feet apart from each other. What types of birds are visiting the feeders? At the end of the day, go look at the bird feed. Was there one seed that was more popular than other seeds within the feed?

Although California only produces less than 1% of the world’s olives (major producers are Spain and Greece), it is the only commercial olive growing state in the U.S.! With a near 400 olive growers in the state, California has over 40,000 acres of olive trees producing on average 81,000 tons of table olives and more than 4 million gallons of olive oil. With around 75 different types of olives grown, there are many options available for olive oils! The Arbequina olive is the most popular type of olive used for olive oil.
Once harvested, they are rushed to the mill, rinsed in fresh water, separated from leaves and stems, and ground into a paste. The paste is then mixed to encourage the oil to separate from the surrounding vegetable matter and water! Check out this video showing how olives are turned into oil!
For over 5,000 years, olives have been cultivated in the Mediterranean! Olive oil has historically been used for religious rituals, medicines, soap-making, body care, and fuel in oil lamps! Today’s activity is to make your own olive oil! This recipe uses kalamata olives, but you can experiment and try any type of olive! Use your olive oil for the STEM activity below!
