Biomedical Engineering and the Human Body
Human beings are fascinating and complex living organisms — a symphony of different functional systems working in concert. Through a ten-lesson series with hands-on activities students are introduced to seven systems of the human body — skeletal, muscular, circulatory, respiratory, digestive, sensory, and reproductive — as well as genetics. At every stage, they are also introduced to engineers’ creative, real-world involvement in caring for the human body.
Living with Your Liver
Students learn the function of the liver and how biomedical engineers can use liver regeneration to help people. Students test the effects of toxic chemicals on a beef liver by adding hydrogen peroxide to various liver and salt solutions. They observe, record and graph their results.
Students are introduced to several key concepts of electronic circuits. They learn about some of the physics behind circuits, the key components in a circuit and their pervasiveness in our homes and everyday lives. Students learn about Ohm’s Law and how it is used to analyze circuits.
Floating and Falling Flows
Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a lighter fluid. In both cases, they see and record beautiful fluid motion. Activities are also suitable as class demonstrations. The natural beauty of fluid flow opens the door to seeing the beauty of physics in general.
Scale Model of the Earth
In this activity, students gain an understanding of the layers of the Earth by designing and building a clay model.
Students explore how different materials (sand, gravel, lava rock) with different water contents on different slopes result in landslides of different severity. They measure the severity by how far the landslide debris extends into model houses placed in the flood plain. This activity is a small-scale model of a debris chute currently being used by engineers and scientists to study landslide characteristics. Much of this activity setup is the same as for the Survive That Tsunami activity in Less
Seismology in the Classroom
Students learn about seismology by using a sample seismograph constructed out of common classroom materials. The seismograph creates a seismogram based on vibrations caused by moving a ruler. The students work in groups to represent an engineering firm that must analyze the seismograph for how it works and how to read the seismogram it creates.
Build it Better!
Students use their knowledge of tornadoes and damage. The students will work in groups to design a structure that will withstand and protect people from tornadoes. Each group will create a poster with the name of their engineering firm and a picture of their structure. Finally, each group will present their posters to the class.
Where Am I: Navigation and Satellites
How do we know where we are? What happens if you are completely lost in the middle of nowhere? Does technology provide tools for people lost in their travels? A person cannot usually determine an accurate position just by looking out a window in the middle of the ocean or vast area of land, particularly if it has not been charted before. In this lesson, students explore the concept of triangulation that is used in navigation satellites and global positioning systems designed by engineers. Also,
Students will design and build a device to protect and accurately deliver a dropped egg. The device and its contents represent a care package that must be safely delivered to people in a disaster area with no road access. In a similar fashion to a team of design engineers, students will design their devices using a number of design constraints including limited supplies. The activity emphasizes the change from potential energy to kinetic energy of the device and its contents and the energy trans
Students will learn about the importance of water and the role it plays in our lives. Students will be exposed to what must occur each day so that they can have clean water.
The Boxes Go Mobile
To display the results from the previous activity, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved.
Heredity Mix ’n Match
Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple’s offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the “couples” in
The Evening News
In this lesson, the students will summarize their experiences in the Amazon rainforest by developing and presenting a briefing for a T.V. evening news program.
How it's Made - Lithium Ion Batteries
Batteries are examples of stored energy, chemical potential energy to be exact. But how are batteries made and what is inside? This is a segment from the Discovery Channel series "How it's Made" on lithium ion batteries.(05:36)
Six Science bloggers talk about why they blog, the role of blogging in science, feedback they've received, and the greatest microbiological discovery in the past decade.
LC Calc (TM) Online. A handy calculator for HPLC computations.
This site contains several on-line calculators for use in liquid chromatography. These include pressure unit conversion, buffer pH, and scale-up factors. Some links may be broken.
Changing the World: Jeff Freeman
Oregon State University alum Jeff Freeman is making the world a better place. He is currently the Knife Innovation Manager at Gerber Legendary Blades.
Animation of Single Head Check Valve HPLC Pump
This animation site is specifically about reciprocating pumps for liquid chromatography. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) are also listed on ASDL.
GC coating animation
This site is one in a series of sites with very good animations related to separations. This animation deals specifically with solute retention in GC. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) are a
