Students operate mock 3D bioprinters in order to print tissue constructs of bone, muscle and skin for a fictitious trauma patient, Bill. The model bioprinters are made from ordinary materials— cardboard, dowels, wood, spools, duct tape, zip ties and glue (constructed by the teacher or the students)—and use squeeze bags of icing to lay down tissue layers. Student groups apply what they learned about biological tissue composition and tissue engineering in the associated lesson to design and fabricate model replacement tissues. They tangibly learn about the technical aspects and challenges of 3D bioprinting technology, as well as great detail about the complex cellular composition of tissues. At activity end, teams present their prototype designs to the class.

This is an introductory lesson on cells. Student learning begins with the teacher modeling the use of a T-chart graphic organizer while reading an article comparing simple and complex carbohydrates. Students then move to independent practice using the T-chart graphic organizer to compare simple (prokaryotic) cells and complex (eukaryotic) cells.

Students learn about the current applications and limitations of 3D bioprinting, as well as its amazing future potential. This lesson, and its fun associated activity, provides a unique way to review and explore concepts such as differing cell functions, multicellular organism complexity, and engineering design steps. As introduced through a PowerPoint® presentation, students learn about three different types of bioprinters, with a focus on the extrusion model. Then they learn the basics of tissue engineering and the steps to design printed tissues. This background information prepares students to conduct the associated activity in which they use mock-3D bioprinters composed of a desktop setup that uses bags of icing to “bioprint” replacement skin, bone and muscle for a fictitious trauma patient, Bill. A pre/post-quiz is also provided.

Proteins are an essential ingredient of each and every cell and constitute most of its dry mass. This Mini Lecture explores the chemical structures of the macromolecules and introduces to the specific, three-dimensional constitution of the amino-acid-chain, the buildup and degradation of proteins with lecture snippets of Nobel Laureates Christian Anfinsen and Johann Deisenhofer.

Students study the three main physical properties of leaves (shape, edge/margin and venation). Students will use the elements of art to describe and classify the observable properties of leaves. They will create an interpretive work of art that responds to these properties.

All living things are organized. From the simplest molecule to most complex ecosystem, living organisms have structures that perform tasks at every level. From reproduction to gathering energy, even simple single celled organisms have organization. In this seminar we will explore how living things are organized, from the smallest particles imaginable to the most complex ecosystem on Earth.StandardsBIO.A.1.2.2 Describe and interpret relationships between structure and function at various levels of biological organization (i.e., organelles, cells, tissues, organs, organ systems, and multicellular organisms)

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye. Learners will be surprised to discover the range of sizes in the microscopic world. This activity can be followed up with a second activity, "What's in a microbe?", located on page 3 in the same resource.
In this activity, learners explore the "nuts and bolts" of gene chips. …
In this activity, learners explore the "nuts and bolts" of gene chips. Learners construct a simple model of a DNA microarray (also known as gene chips) and learn how microarrays can be used to identify and treat disease--including cancer. This resource includes references and an explanation of microarrays.

Students will learn that all organisims are composed of cells, the building-blocks of life. Most cells are microscopic and must be magnified to be observed. Students will make slides of cells from an onion skin and Elodea (American or Canadian waterwee) to observe under a microscope.
