This pathway provides an introduction to nucleic acids and their role in providing heritable information in cells. For a deeper look at this topic, we recommend the pathway DNA Structure and Function from the OpenStax textbook Biology for AP® Courses.
This interactive outlines the nature of nucleotide base-pairing and the structure of DNA
This activity is an investigation where students observe cells from various organisms and then compare and contrast the cells they observe.
This is a classroom activity in which students observe and describe cells in stages of division. They share observations about what they see in the cells, then formulate questions and do research concerning the changes that take place in cells during the process.
In this lesson, students will use the Arcadia Earth app to learn about and develop a foundational understanding of our oceans.
Estimated time required: 1 class period.
Technology required for this lesson: Tablet or Smartphone.
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.
In the Arcadia Earth app section titled “Sustainability Beneath the Surface,” students are introduced to several factors that impact ocean health. This lesson takes a deeper dive into one specific challenge: overfishing. Through the game, “One Fish, Two Fish,
Overfishing, NO Fish,” students discover how fishing management reformation is necessary to sustain fish populations and prevent permanent supply collapses.
Estimated time required: 1 class period.
Technology required for this lesson: Tablet or Smartphone.
In deze simulatie kunnen gebruikers oefenen met het gebruik van een micropipet in een virtuele labomgeving. De vaardigheden die in deze simulatie worden geoefend, zijn het pipetteren van verschillende hoeveelheden vloeistof met een P20-micropipet en het gebruiken van de eerste en tweede stop.
In this biology activity, students will first brainstorm how humans use their hands. They will then conduct a short experiment to determine the importance of the opposable thumb to humans and how it is an important adaptation.
This evolution plug in was designed for teachers and informal educators to conduct with their students at an orangutan exhibit . The students will learn basic natural history information about orangutans, how to conduct basic behavioral research.
PCR, or polymerase chain reaction, is a powerful lab technique used to generate billions of copies of a specific stretch of DNA. This video animation illustrates the process of PCR.
This lab video demonstrates how to perform a PCR (Polymerase Chain Reaction) in the laboratory setting.
This interactive will present the components and steps needed for a successful
PCR reaction.
This interactive will present the rules for designing precise nucleotide sequences
called PCR primers. Designing primers for a PCR reaction is an important step
because the way they bind to the template DNA dictates much of the success of
the PCR reaction.
Paleontologist Lee Hall takes us on a tour of the Museum's fossil preparation lab. Worksheets available for grades 1-2.
In this activity students analyze a familys pedigrees to make a claim based on evidence about mode of inheritance of a lactose intolerance trait, determine the most likely inheritance pattern of a trait, and analyze variations in DNA to make a claim about which variants are associated with specific traits. This activity serves as a supplement to the film Got Lactose? The Co-evolution of Genes and Culture (http://www.hhmi.org/biointeractive/making-fittest-got-lactase-co-evolution-genes-and-culture). The film shows a scientist as he tracks down the genetic changes associated with the ability to digest lactose as adults. A detailed teachers guide that includes curriculum connections, teaching tips, time requirements, answer key and a student guide can be downloaded at http://www.hhmi.org/biointeractive/pedigrees-and-inheritance-lactose-intolerance. Six supporting resource and two click and learn activities are also found on the link.
This article introduces the 17 species of penguins and shows how a study of penguin habitats and life cycles can fulfill national science content standards for K-grade 5. The author provides links to web resources and suggests books. The article appears in the free, online magazine Beyond Penguins and Polar Bears.
This lesson covers the process of photosynthesis and the related plant cell functions of transpiration and cellular respiration. Students will learn how engineers can use the natural process of photosynthesis as an exemplary model of a complex yet efficient process for converting solar energy to chemical energy or distributing water throughout a system.
This pathway provides an introduction to cellular metabolism, including a comparison of the processes of photosynthesis and cellular respiration. For a deeper look at this topic, we recommend the pathways Metabolism, Cellular Respiration and The Biological Process of Photosynthesis from the OpenStax textbook Biology for AP® Courses.
Students receive information about cladistics and apply this phylogenetic approach to two problems, collecting data, determining whether traits are ancestral or derived, and using this information to select the most parsimonious tree.
