1. Teacher Guide This lesson is designed to teach kids to ask a critical thinking question that you can’t just put into a search box to solve. To do that, we encourage them with smaller questions that search can help them answer. Make sure that you read the notes for each slide: they not only give you teaching tips but also provide answers and hints so you can help the kids if they are having trouble.

3. After nearly 20 years of proposals, research, preparation, and construction, the Atacama Large Millimeter Array (ALMA) observatory became fully operational in March, 2013. Currently, it’s the most expensive terrestrial astronomy observatory in history, with a final price tag of about $1.4 billion. But that money – put up by organizations from Canada, Chile, Japan, South Korea, the United States, and Taiwan – will be put to good use for the next 50 years. ALMA’s location, on Chajnantor plateau in the Atacama Desert of Chile, puts it at an altitude of more than 3 miles above sea level. The lack of cloud cover and extreme elevation drastically reduces interference for the 66 radio antenna telescopes that comprise the array. In the two years since ALMA astronomers began work in earnest, the technology and location have proved key in helping to gather detailed images of our solar system, galaxy, and beyond, to even the farthest reaches of the universe.
