Students learn some of the implications of 3D printing in the biomedical field. Unlike 3D printers used in a classroom or by consumers, which use a plastic filament to produce a product, 3D printing for medical purposes is often with real living cells. In this lesson, students gain an understanding of how 3D printing is changing lives for the better through a presentation and group discussion. In the corresponding activity, they have the opportunity to participate in a hands-on simulation of a real-world 3D printing task.

his is a fun, casual “mini discussion” that can be used to get students generating and sharing ideas in a low-stakes setting, and to help build a culture of discourse and develop discussion skills within a group. It’s an interesting and fairly easy topic for students to think about and participate in. Students tend to love talking about the “most,” “least,” and “how many” facts about nature. The very broad category of “organism” means all students will probably have something to contribute to the discussion. Engaging in this kind of talk can help prepare a group to participate in similar or more involved discussions later, and it can “run in the background” while the group is eating lunch or a snack, or whenever they seem ready to sit and chat.

Students perform an activity similar to the childhood “telephone” game in which each communication step represents a biological process related to the passage of DNA from one cell to another. This game tangibly illustrates how DNA mutations can happen over several cell generations and the effects the mutations can have on the proteins that cells need to produce. Next, students use the results from the “telephone” game (normal, substitution, deletion or insertion) to test how the mutation affects the survivability of an organism in the wild. Through simple enactments, students act as “predators” and “eat” (remove) the organism from the environment, demonstrating natural selection based on mutation.

Students learn about mutations to both DNA and chromosomes, and uncontrolled changes to the genetic code. They are introduced to small-scale mutations (substitutions, deletions and insertions) and large-scale mutations (deletion duplications, inversions, insertions, translocations and nondisjunctions). The effects of different mutations are studied as well as environmental factors that may increase the likelihood of mutations. A PowerPoint® presentation and pre/post-assessments are provided.

A career with NOAA could launch you all over the world, from the warm waters of the Caribbean to the winter wonders of the South Pole. The challenges are endless. Employment in NOAA is a job with a mission. At NOAA, safeguarding the public, protecting natural resources, strengthening the economy. It's all in a day's work. Imagine yourself. Careers in NOAA are as diverse as the line offices that make up the agency. More information can be found on the Office of Workforce Management website.

This activity sets an exciting tone of exploration and discovery, encouraging an inquiry mindset in students that helps establish a community of curious, active learners. Students gain tools to explore the natural world—and are inspired to discover and attempt to explain the abundant nature mysteries that surround us. NSI works well at the start of a field experience, to get students excited about nature mysteries. It provides an opportunity for an instructor to coach students in inquiry skills, by using the language of science and engaging in scientific discussions. For instructors with less experience leading open-ended explorations and discussions, this can be a challenging activity to lead successfully the first time. The write-up includes detailed support, by providing information and strategies for the instructor. Students focus on a mystery object, generate observations, questions, evidence-based explanations and share what they already know from other sources. Once students are familiar with these practices, they can use them to investigate and make explanations about anything they find in nature through their field experience(s).

Students watch video clips of animals and plants in their natural environments to determine what living things need to survive. They will then complete an illustration of their own real or imagined plant or animal fulfilling one or more of their needs for survival, within their natural environment. While this lesson does a good job explaining how animals meet their needs through their environments, additional lessons and experiences with plants would need to be provided in order to meet the full standard.

Stimulate a neuron and monitor what happens. Pause, rewind, and move forward in time in order to observe the ions as they move across the neuron membrane.

It can be hard to make learning about the night sky student-centered, but that’s what this activity does: students trade and discuss cards, then take charge of finding and pointing out the different objects. When an object is found, the instructor may share some interesting information to feed students’ curiosity, but the primary focus is on students finding, wondering about, and discussing different objects.
During this activity, students try to find and discuss a variety of items during a night hike, such as, “evidence of an amphibian (frog croaks),” puzzlers that they’re challenged to figure out, such as “the fastest thing in the Universe” (light), and items from the night sky, such as “a natural satellite of Earth” (the Moon), or “something bigger than our Sun,” (other stars).

Student teams create, test and improve oil spill cleanup kits, designing them to be inexpensive and accessible for homeowners to use or for big companies to give to individual workers to aid in personal home, community or corporate environmental oil cleanup. After deciding on a target user and scenario, teams conduct research and draw from an assortment of ordinary materials and supplies made available by the teacher. As a concluding gallery walk, each group presents its final prototype and summary poster to the rest of the class.
