Meteor Shower Power
Two eye-catching meteor showers occur during the Northern Hemisphere’s summer. In July, 20 meteors an hour fly through the sky during the Delta Aquarid shower. And up to 60 meteors an hour soar overhead during August’s Perseid shower.
You know it's summer when the crickets start chirping. Crickets actually change their tune depending on the temperature. The hotter it is, the faster they chirp. You can even calculate how hot it is by listening and counting a cricket’s chirps. To get the temperature in degrees Fahrenheit, just count the number of chirps in 15 seconds and add 37.
Flowers aren’t the only things that pop up in summer. The Eiffel Tower in Paris, France, can “grow” over six inches taller during the season when heat makes its iron expand. Scientists even think your nails grow faster at this time, though they’re not completely sure why.
