This activity is a field investigation where students gather data on physical changes of the ecosystem surrounding their school habitat.
Bug Hunt uses NetLogo software and simulates an insect population that is preyed on by birds. There are six speeds of bugs from slow to fast and the bird tries to catch as many insects as possible in a certain amount of time. Students are able to see the results graphed as the average insect speed over time, the current bug population and the number of insects caught. There are two variations to try for the predator, one where the predator pursues the prey and one where the predator stays still and captures insects that pass nearby. In the first case the bird catches the slow insects and the faster ones survive, reproduce and pass genes on. The average speed of bug should increase over time. In the second case the faster bugs come near to the bird more often than the slow ones. The slow ones survive more, reproduce and pass their genes on.
This activity is a biology lab investigation where students create habitats to observe decomposers in a controlled setting.
In this activity, you will build a bird feeder to attract birds, so you can study them.
This pathway describes how DNA ligase, a key enzyme in DNA replication, is used in gene cloning to create a recombinant plasmid. This pathway supports ABE lab 3: Building a Recombinant Plasmid.
This pathway explains how restriction enzymes are used in gene cloning to obtain the DNA pieces that will create a recombinant plasmid. This pathway supports ABE labs 2, 2a, 3, 4, and 4a.
Submitted as part of the California Learning Resource Network (CLRN) Phase 3 Digital Textbook Initiative (CA DTI3), CK-12 Foundation’s high school Biology FlexBook covers cell biology, genetics, evolution, ecology, botany, zoology, and physiology. This digital textbook was reviewed for its alignment with California content standards.
CK-12’s Life Science delivers a full course of study in the life sciences for the middle school student, relating an understanding of the history, disciplines, tools, and modern techniques of science to the exploration of cell biology, molecular biology, genetics, evolution, prokaryotes, protists,fungi, plants, animals, invertebrates, vertebrates, human biology, and ecology. This digital textbook was reviewed for its alignment with California content standards.

Guest lecture recorded July 28, 2020 with Professor Richard Sherwood, Assistant Professor of Medicine at Brigham and Women’s Hospital. Molecular cloning is essential to research in genetics and cell biology. In this webinar, Dr. Sherwood shares how his lab uses molecular cloning to power their work in genetics and CRISPR/Cas9 genome editing.
The CRISPR-Cas9 editing tool causes a double-stranded break in target DNA that immediately triggers cellular DNA repair mechanisms to fix this dangerous situation. These repair mechanisms can be taken advantage of by scientists to disrupt or precisely change genes.
This video shows how the Cas9-gRNA complex cleaves DNA visualized in real-time using atomic force microscopy. Astonishingly, single molecules of Cas9 and DNA can be made visible with this technology.
This video illustrates how to test guide RNAs to facilitate the cleaving of a macrophage gene in vitro.
Guest lecture recorded July 30, 2020 by Dr. Jessica Whited, Assistant Professor of Stem Cell and Regenerative Biology at Harvard University. Dr. Whited studies limb regeneration in axolotl salamanders, with the ultimate goal of discovering how to regenerate limbs in patients. In this webinar, Dr. Whited discusses how her work involves using Cas9-mediated gene drives to generate axolotls with the desired genetic backgrounds.
This scrollable introduces CRISPR's native role as a bacterial defense system. The gene editing tool CRISPR-Cas9 derives from it.
