Genetics with a Smile

(View Complete Item Description)

Students use pennies to determine the traits for a smiley face, then use Microsoft Word to create the smiley face. Faces are displayed in the classroom and students use their knowledge of genetics to answer questions about smiley faces, traits, and probability. NOTE: Teacher notes and a "Wrapping It Up" analysis activity are separate complementary resources.

Activity 2A: Just a Little Bit of Effort

(View Complete Item Description)

In this activity, students will explore the parts of a lever and will build a model of each class of lever on a wooden stand using dowels and modified wooden rulers. Using a spring scale and hanging weights, students will study the forces and will determine the advantage of each type of lever. As a grand finale to the activity, students will apply their newly found knowledge of levers as they compete in a contest called the â€œLittle Bit of Effort Contest.â€ Students will work in their groups to design the most efficient lever in each class, i.e., the lever that can move the most weight with the least amount of effort.

Activity 3A: Levers in the Body: They Are Not What You MIght Think!

(View Complete Item Description)

In this activity, students will use a model of the human arm, including an artistically modified scapula, humerus, radius and ulna. After measuring the weight of the forearm on their model with a spring scale, they will assemble the bones so that the elbow joint is movable. Once students have assembled the model, they will attach string â€œbiceps and triceps musclesâ€ to the model at origin points labeled on the model. An approximation of the actual insertion point will be labeled on the model and the other end of the string â€œmuscleâ€ attached to that location. The student will then investigate how the biceps muscle operates the joint as a lever system, exploring angles and the resistance and effort forces. Next, students will move the insertion point of the string muscle to examine how the lever system changes. Both the triceps and biceps will be studied in this part of the activity. Finally, using body segment weight percentages, students will relate their findings to their own bodies.

Helping Hand

(View Complete Item Description)

In this invention challenge activity, students see how many objects they can grab with a homemade "bionic" arm. Students will follow the design process to build a grabber that can reach at least two feet, develop a way to open and close the grabberâ€™s jaw, and figure out how to connect the â€œjawâ€ to a stick. Educators can use this activity to introduce learners to the design process as well as simple machines (lever, fulcrum).

Micro Organs

(View Complete Item Description)

This multimedia resource, part of the NC Science Now series, describes how researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine are applying their understanding of the hierarchical structural organization of multicellular organisms to culture a variety of human tissues. By growing miniature human livers, hearts and kidneys and linking them together with a blood substitute, they can evaluate the effects of new drug therapies. Components of this resource include a video and a related blog article. Links to these components are provided on the page under the heading "UNC-TV Media."

Biological Levels of Organization

(View Complete Item Description)

Students will observe that biological organization is a hierarchial system of classification in which each successive level is more complex than the lower level, and each successive level has properties that did not exist before. Students will sequence the levels of organization and make a foldable that lists and describes the levels.
