Tuesday, July 20, 2021, is National Moon Day and the 52nd anniversary of when Neil Armstrong walked on the moon during the Apollo 11 mission. The day is also to celebrate future launches into space, which you can learn about on NASA’s website here.
To celebrate National Moon Day, try one of the activities on the blog, STEMsational. They have links to activities like making moon dust and learning about the phases of the moon.
To make a mission like Apollo 11 a success, many people worked hard to come up with the right space suit, rocket, and more. You can learn about this in many books in the library including:
You may have been hearing a lot about the emergence of periodical cicadas this year. It is an exciting year for those in the range for this year’s emergence. Here is a little info about these unique insects.
What is a periodical cicada?
Periodical Cicadas have a life cycle that lasts either 13 or 17 years, and all of them in an area emerge as adults at once. These cicadas emerge in difference parts of the country at different times, and each group is given a brood year. The brood in the news this year, brood x, does not reach into northern Illinois, so we will not be seeing them this year.
Feeling left out?
Not to worry, we will get to see some periodical cicadas soon! Northern Illinois should see periodical cicadas in the early summer of 2024. Get your recipes ready!
Cicadas are edible! They taste like almonds (I have read). Every year many people try them (although, try them with caution as they can trigger shellfish allergies). They also cause a bit of a boom in forests as many animals have more babies in years when the periodical cicadas emerge due to the increase in insects to eat. In the years following a large emergence, even tress grow more because of the increase in nutrients from the cicada bodies that decompose on the forest floor.
Aren’t there cicadas every year?
Yes! Every summer cicadas emerge, but those are annual cicadas, also known as dogday cicadas. They have also have a long lifespan, usually living underground for 2-5 years before emerging as adults.
Saturday, May 15, 2021 is Astronomy Day! This day is a great time to learn more about astronomy and do fun activities inside or outside.
Astronomy is the study of the universe beyond the Earth including the sun, moon, stars, and more. To learn more about astronomy, use your MPPL library card to access the many web resources we have available. You can find the kid focused web resources on the Homework Help Web Page.
One activity you can do with your family is track the moon phases. Every night, the moon looks a little different. This is due to how the sun is reflecting off the moon. To track these changes, create a journal with your nightly observations.
Arbor Day is on Friday, April 30. It is an annual holiday encouraging people to plant and care for trees. It was initiated by Julius Sterling Morton, President Grover Cleveland’s Secretary of Agriculture in 1872.
Water that you find in nature is not necessarily clean or pure; you would not want to drink pond water, for example. There are ways to clean water, though, and you can try this experiment at home!
First, take a clean jar with a lid and fill it with water from a lake, pond, stream, or any other source of water outside your home. Put the lid on until it is time for the next step. What do you notice about the water?
To clean the water, you will need something called alum. Alum is a hydrated double sulfate of aluminum and potassium, used in dyeing and tanning. If you don’t have this at home, it can be found in the spice aisle in the grocery store.
Put 2 tablespoons of alum in your water, close the lid tightly, and shake it up. Then let the water sit for a few hours.
When you look at your jar again, what do you see?
You may notice that the dirt gets pulled to the bottom. In a real water treatment plant, the added alum forms clumps with the dirt and pulls it down to the bottom of the basin.
