This printable would be great for middle school/junior high science or math. It covers basic elements as well as converting percents to decimals, and to fractions. In this packet, you will receive 2 worksheets.
The first worksheet covers reading about the elements in the body and listing the elements in order along with the percents of each element. The second worksheet students will create a pie chart and convert the percents to decimals and to fractions.
This is great review to also discuss place value and having students read decimals properly.
