This is a comprehensive textbook covering life functions that are ultimately interpretable in chemical terms, as chemistry is the logic of biological phenomena.
In this activity, students will design a process that removes the most iron from the cereal. This activity is meant for the students to experiment with different materials using what they know about iron, magnets, and forces to design the best process for removing the iron from the cereal.
Chemical composition of Portland cement.
In this lesson, students will learn that minerals are a necessary part of our diet. They will learn that different minerals have different functions in the body. More specifically, they will discover that iron is necessary to carry oxygen around the body. In the associated activity, students will design a process that removes the most iron from the cereal.
This animated segment from KET's Electronic Field Trip to a Horse Farm demonstrates one of the ways calcium, a naturally occurring mineral derived from limestone, enters a horse's diet to give it an advantage in bone strength.
Preventing absorption of water in Portland cement.
How Portland cement absorbs water.
Muscles and Bones offers teachers 10 activities that help students understand how the body's muscles and bones work. The activities in this guide help students explore important questions related to muscles and bones in living things; such as: Do you know which foods have lots of calcium for your bones? What are you doing to keep your muscles strong? and How do your bones and muscles work together?
In NASA CONNECT Better Health From Space to Earth, students will learn about the importance of good nutrition and exercise. They will investigate what we can learn in space about our bodies here on Earth. Students will see how researchers and scientists apply the mathematics concepts of measurement and estimation to study the loss of calcium in bones and the loss of muscle mass while astronauts are living and working in space. Grades 6-8.
Investigate why astronauts need calcium in space and observe that bones can be hollow and strong.
Cement production may be classified by application into two primary groups: construction and energy services. The construction applications for cementing consume the lion’s share of cement manufactured world-wide, but the cement produced for energy services applications is an integral part of meeting the world’s energy needs and requires tighter quality control standards to meet that industry’s higher demands on control of the rheological properties of the fluid slurry state, the solid state, and especially the transition from the former state to the latter, or the setting process. Applications relating to the energy services industry are the primary focus of this work. Additionally, cement may also become central to efforts in nuclear waste management by locking radioactive material within the cementitious matrix, where rates of diffusion of waste out of the cement serve as the dominant concern. These modules explain the chemistry of Portland cement and its applications for the energy industry.
