Could you do with a quality resource on relative and absolute/radiometric dating of rocks for your senior biology students? Do you find they're having trouble getting their heads around concepts such as half-life and the decay of radioactive isotopes?

These professionally created, human generated and visually stimulating task cards will help your students gain a better understanding of how things such as the stratigraphic method, use of index fossils and radioactive isotopes can help determine relative and/or absolute age of rock.

Suitable for students in Grades 10 - 12, Relative & Absolute/Radiometric Dating of Rocks, Index Fossils - Task Cards will save teachers lots of valuable prep time! Simply print each page, laminate and cut the cards apart - you then have them forever!

Included:

1. 20 Task Cards (printable PDF) in two different sizes: larger, one-per-page and smaller four-per-page if you prefer to save on printing.
2. 23 Answer Cards (printable PDF).
3. Task Cards (digital/PowerPoint display version).
4. Answer Cards (digital/PowerPoint display version).

Relative & Absolute/Radiometric Dating of Rocks, Index Fossils - Task Cards covers the following content:

• difference between relative and absolute dating
• the stratigraphic method of determining the relative age of rocks
• principle of superposition
• what are index fossils?
• using index fossils to determine relative age of rock strata
• radiometric dating to determine absolute age of rocks
• what are (i) isotopes (ii) radioactive isotopes?
• use of radioactive isotopes in radiometric dating
• comparing the 'half-life' of different radioactive isotopes
• carbon-14 dating of organic matter

Task cards are a versatile tool to use in the classroom. They can be set up at stations around the room or assigned to individuals or small groups. They can be used as review exercises or perhaps as a short research activity. Relative & Absolute/Radiometric Dating of Rocks, Index Fossils consists of 20 cards, and you can use as many or as few as you like based on their suitability to the curriculum or to the particular needs of your students.

Each task card has a question or short research task for students to complete. The cards are divided into two types, those with standard questions (labeled green) and those with more challenging questions (labeled red). If you're setting the cards up at stations, you can include one of each, giving students a choice.

Relative & Absolute/Radiometric Dating of Rocks, Index Fossils - Task Cards comes with an Answer Key (PowerPoint and printable PDF versions included) with images in full colour that look great on the big screen and can be used to facilitate good class discussion. Answers are highly detailed and have been thoroughly checked for accuracy so there is no need to research or fact-check here; it's all been done for you.

* Please note that many of the questions/tasks in this resource are also available in the form of printable worksheets if you prefer:
