The task requires the student to use logarithms to solve an exponential equation in the realistic context of carbon dating, important in archaeology and geology, among other places. Students should be guided to recognize the use of the natural logarithm when the exponential function has the given base of e, as in this problem. Note that the purpose of this task is algebraic in nature -- closely related tasks exist which approach similar problems from numerical or graphical stances.

In the task "Carbon 14 Dating'' the amount of Carbon 14 in a preserved plant is studied as time passes after the plant has died. In practice, however, scientists wish to determine when the plant died and, as this task shows, this is not possible with a simple measurement of the amount of Carbon 14 remaining in the preserved plant. The equation for the amount of Carbon 14 remaining in the preserved plant is in many ways simpler here, using 12 as a base.

This problem introduces the method used by scientists to date certain organic material. It is based not on the amount of the Carbon 14 isotope remaining in the sample but rather on the ratio of Carbon 14 to Carbon 12. This ratio decreases, hypothetically, at a constant exponential rate as soon as the organic material has ceased to absorb Carbon 14, that is, as soon as it dies. This problem is intended for instructional purposes only. It provides an interesting and important example of mathematical modeling with an exponential function.

This exploratory task requires the student to use a property of exponential functions in order to estimate how much Carbon 14 remains in a preserved plant after different amounts of time.

This online lab exercise focuses on the processes involved in the Carbon cycle and the influences of human activity on those processes- especially as they relate to Earth's weather and climate. The fourth in a 10-part lab series on weather and climate, this lab exercise is designed for first and second year college geoscience students (majors and non-majors) as well as pre-service STEM teachers.

Students are introduced to the concept of energy cycles by learning about the carbon cycle. They will learn how carbon atoms travel through the geological (ancient) carbon cycle and the biological/physical carbon cycle. Students will consider how human activities have disturbed the carbon cycle by emitting carbon dioxide into the atmosphere. They will discuss how engineers and scientists are working to reduce carbon dioxide emissions. Lastly, students will consider how they can help the world through simple energy conservation measures.

Multimedia educational resources such as video clips, digital interactive explorations and a quiz are included. This is the fifth of ten self-paced professional development modules providing opportunities for teachers to learn about climate change through first-hand data exploration. A carbon consumption calculator designed for kids to be used in the classroom and glossary links to vocabulary are included.

Science Background: • Sulfuric acid removes water from the sugar (Dehydration). • Reaction is very exothermic (releases heat) • With water removes you are left with elemental carbon • Much of the water is boiled off as steam
Directions: 1. Fill beaker 2/3 full of sugar. 100-250 mL is a good size 2. Add concentrated Sulfuric Acid so it just covers sugar 3. Mix with glass stir rid (you may need to add some more acid) 4. When beaker heats up (sugar turns brown) stop stirring. 5. Reaction may take a few minutes. Be patient.

We take a look at the basic composition of blood. Blood is composed of liquids and solids. The solids are called the formed elements while the liquid portion is called plasma. The solids of the blood consists of red blood cells, white blood cells and platelets . The plasma is mostly water, but it does contain some plasma proteins, dissolved gases, nutrients and electrolytes.

In this video take a look at hematopoiesis (haematopoiesis), or the creation of blood. While we are still embryos the formation of blood can occur in multiple sites. After birth production primary takes place in red bone marrow.
All blood cells that are circulating derive from pluripotential hematopoietic cells also known as hematopoietic stem cells (HSCs). These stem cells can form any of the blood cells or other stem cells. Hematopoietic Growth Factor will help determine what the stem cell grows into.
There are three families that blood cells can grow up to become: 1) Erythroid cells, 2) Lymphocytes, and 3) Myelocytes.

Red Blood Cells also known as red blood cells (RBCs) or erythrocytes are around 7.5μm in diameter. The average number (red blood cell count) is typically: *5,200,000 per cubic millimeter ± 300,000 men *4,700,000 per cubic millimeter ± 300,000 women
Red blood cells are made of hemoglobin. When the hemoglobin combines with oxygen it is called oxyhemoglobin, when oxygen has been released it is known as deoxyhemoglobin. The RBC initially have a nuclei during the early stages of development, they then remove the nuclei to help make room for hemoglobin.
