The Earth Moon System Let S Talk Science

The Earth Moon System Let S Talk Science The moon revolves around earth once every 27.3 days. we call this length of time a lunar month. the time it takes for the moon to rotate once on its axis is about 27 earth days. this is a lunar day. for comparison, the earth completes one rotation every 24 hours and the moon completes one rotation every 709 hours. Learn the basics of the star we call the sun in this backgrounder by let’s talk science. the earth moon system (2022) this backgrounder by let’s talk science has answers to some common questions about earth’s moon. how to safely watch a solar eclipse (2024).

The Earth Moon System Let S Talk Science The earth moon system. eight days after its final encounter with the earth, the galileo spacecraft looked back and captured this remarkable view of the earth and moon. the image was taken from a distance of about 6.2 million km (3.9 million miles). the picture was made with images taken through the violet, red, and 1.0 micron infrared filters. Action choice 1: observing and measuring a simulated solar eclipse. 45 minutes. in student pairs. students measure and record lux levels during a real or simulated solar eclipse and make a graph using their data. action choice 2: observing and measuring a solar eclipse in real time. 45 minutes. in student pairs. So here are 10 things we’ve learned about earth by studying our closest neighbor. 1. the makeup of a newborn earth. the moon is not made of cheese; it’s made of remnants of a baby earth! scientists believe that a mars sized object crashed into earth 4.5 billion years ago. With a radius of about 1,080 miles (1,740 kilometers), the moon is less than a third of the width of earth. if earth were the size of a nickel, the moon would be about as big as a coffee bean. the moon is an average of 238,855 miles (384,400 kilometers) away. that means 30 earth sized planets could fit in between earth and the moon.

The sun’s gravity pulls on earth’s water, while the moon’s gravity pulls on the water in the same places. the high tide produced by sun adds to the high tide produced by the moon. so spring tides have higher than normal high tides. this water is shown on the picture as the gray bulges on opposite sides of the earth. For younger students, you can tell them the moon’s diameter is approximately 0.25 or ¼ that of earth (3,475 km (moon diameter) 12,742 km (earth diameter) = ~0.25). once the scale moon diameter has been determined, re inflate the balloon. verify accuracy by measuring the scale moon’s diameter using the method described above.
