There are hundreds of billions of stars in our Milky Way galaxy. The Milky Way itself is only one of hundreds of billions of galaxies. Since our sun is an average-sized star, scientists have long hypothesized that many other stars have planets orbiting them. However, until recently we had no evidence about planets orbiting other stars. There is a saying that states, Continue reading the story "The solar system consists of planets and other bodies that orbit the Sun in predictable paths"

Measuring is a specific kind of observation skill. Scientists routinely measure weight and volume with balances and graduated cylinders. They often use common tools for measuring length. Estimating is a valuable skill because it can help in selecting the proper equipment and supplies. Estimating can also help avoid making mistakes in expressing answers. If you have Continue reading the story "Measure and estimate the weight, length, or volume of objects"

Differentiate observation from inference (interpretation) and know scientists' explanations come partly from what they observe and partly from how they interpret their observations. All science process skills ultimately depend on the ability to make accurate observations. While observing seems simple, it is much more difficult than most people realize. As one indicator Continue reading the story "Differentiate observation from inference (interpretation)"
