The book Chemistry on a Budget contains inexpensive chemistry labs that are useful with easy to obtain materials.
There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
You can buy this lab book for $23 at amazon.com or lulu.com. It will take 1-2 weeks to get to you -- Order Now. It’s a great resource!

“Sunlight has returned to Antarctica as Southern Hemisphere spring approaches, and NASA’s Terra satellite has had enough daylight to capture an image of a known crack or rift along Larsen C — the continent’s fourth-largest ice shelf. The crack can be seen to have grown considerably longer during the long Antarctic winter night. A group in the United Kingdom – called Project MIDAS – has also been tracking the crack and reported on August 18, 2016 that it has grown 13 miles (22 km) over the past six months. It now stretches 80 miles (130 km).
NASA said on September 8[, 2016] that its scientists can’t predict whether this ice shelf will calve and collapse, as the Larsen A ice shelf did in 1995 and as Larsen B did in 2002. “

“With a gargantuan crack slowly splitting it apart, Antarctica's fastest-melting glacier is about to lose a chunk of ice larger than all of New York City, scientists say. …
The crevasse stretches 19 miles (30 kilometers) long and up to 260 feet (80 meters) wide, as shown in a picture taken by NASA's Terra satellite in October and featured this week as a NASA Image of the Day.
Snaking across the floating tongue of the Pine Island Glacier in West Antarctica, the crack is expected to create an iceberg 350 square miles (907 square kilometers)—versus 303 square miles (785 square kilometers) for Manhattan, Brooklyn, Queens, Staten Island, and the Bronx combined, according to NASA.”

“The crack in Larsen C grew around 30 kilometers (18.6 miles) in length between 2011 and 2015. And as it grew, also became wider — by 2015, yawning some 200 meters in length. Since then, growth has only continued — and now, a team of researchers monitoring Larsen C say that with the intense winter polar night over Antarctica coming to an end, they’ve been able to catch of glimpse of what happened to the crack during the time when it could not be observed by satellite.”

“Higher ocean temperatures are causing the ice to shrink at an accelerating rate, and it’s eroding the ice fringing the continent. That, in turn, opens the ice sheet to further contact with warmer ocean water and increases the amount of ice running into the ocean…”

“Pine Island Glacier is of particular interest to scientists because it is big and unstable and so is one of the largest sources of uncertainty in global sea level rise projections.
A primary goal of Operation IceBridge is to put the same instruments over the exact same flight lines and satellite tracks, year after year, to gather meaningful and accurate data of how ice sheets and glaciers are changing over time. But discovering a developing rift in one of the most significant science targets in the world of glaciology offered a brief change in agenda for the Oct. 26 flight, if only for a 30-minute diversion from the day's prescribed flight lines…
When the iceberg breaks free, it will cover about 340 square miles (880 square kilometers) of surface area. Radar measurements suggested the ice shelf in the region of the rift is about 1,640 feet (500 meters) feet thick, with only about 160 feet of the shelf floating above water and the rest submerged.”
