Periodic Table Scavenger Hunt. The Periodic Table is one of the coolest ideas in science. It is an organisation of the elements by the structure of their atoms. Anything which is matter (gas/solid/liquid/plasma) is comprised of elements from the Periodic Table. You are, your dinner is, your pet is, and toilet paper is!

About 20–25% of the 92 naturally occurring elements are . essential elements. that are necessary for living things. There is some variation: humans have 25 essential elements, while plants have only 17. Four elements—oxygen (O), carbon (C), hydrogen (H), and nitrogen (N)—make up 96% of living matter.

Elements are not changed in normal chemical reactions. Each element has a unique chemical symbol. 92 naturally occurring elements range from hydrogen to uranium. 4 elements (C,H,O,N) make up 96% of most living organisms. Trace elements are necessary, but present in small quantities. Atoms are the fundamental particles of elements
