Task cards are a great way to review, differentiate and add style to your assignment. There are 20 task cards along with an answer key for the teacher and and answer sheet for the students.
The skills involved are: recognizing symbolic representation, multiplication, division, work with fractions, percents. There is one multiple choice question, the rest are all calculation/short answer.
Some of the cards ask about carbon dating, others deal with other radioactive elements such as Americium, Berkelium, Radon, Californium, etc.
The preview will show the type of questions asked. The task cards are one quarter of a page each (just like any generic task card) and have an attractive border around them just as you see in the preview, but it won't use too much ink when printing.
Keywords: radioactive decay, radiometric dating, decay, radiation.
