Hank introduces us to comparative anatomy, which studies the similarities and differences in animal anatomy to support the theory of evolution and the shared ancestry of living things.
In small groups, students experiment and observe the similarities and differences between human-made objects and objects from nature. They compare the function and structure of hollow bones with drinking straws, bird beaks, tool pliers, bat wings and airplane wings. Observations are recorded in a compare & contrast chart, and then shared in a classroom discussion, along with follow up assessment activities such as journal writing and Venn diagrams.
Hank continues our exploration of animal phyla with the more complexly organized annelida and arthropoda, and a biolography on insects.
Students will construct a model of the carbon cycle to explore the cycling of matter in decomposition. Students will design a process to compost food waste and recycle products used during lunchtime to reduce the amount of garbage the school produces.
Concepts of Biology is designed for the introductory biology course for nonmajors taught at most two- and four-year colleges. The scope, sequence, and level of the program are designed to match typical course syllabi in the market. Concepts of Biology includes interesting applications, features a rich art program, and conveys the major themes of biology.
Hank wraps up the Crash Course on ecology by taking a look at the growing fields of conservation biology and restoration ecology, which use all the kung fu moves we've learned about in the past eleven weeks and apply them to protecting ecosystems and to cleaning up the messes that we've already made.
Corals are beautiful, diverse and complex structures. Nearly everyone knows about Coral Reefs, but do you know what they actually are...? Coral Reefs are vital animals that provide the foundation for the richest diversity in the ocean. Explore the important role that corals have for the oceans worldwide, and understand how our small choices can have a powerful impact on life in the ocean.
In this activity, students examine how to grow plants the most efficiently. They imagine that they are designing a biofuels production facility and need to know how to efficiently grow plants to use in this facility. As a means of solving this design problem, they plan a scientific experiment in which they investigate how a given variable (of their choice) affects plant growth. They then make predictions about the outcomes and record their observations after two weeks regarding the condition of the plants' stem, leaves and roots. They use these observations to guide their solution to the engineering design problem. The biological processes of photosynthesis and transpiration are briefly explained to help students make informed decisions about planning and interpreting their investigation and its results.

DNA. It's what makes you unique. Unless you have an identical twin, your DNA is different from that of every other person in the world. And that's what makes DNA fingerprinting possible. Experts can use DNA fingerprints for everything from determining a biological mother or father to identifying the suspect of a crime. What, then, is a DNA fingerprint and how is it made? Here, you'll find out by solving a mystery—a crime of sorts. First, you'll create a DNA fingerprint (we'll supply the lab and all necessary materials). Then you'll compare this DNA fingerprint to those of all seven suspects to nab the perpetrator. Ready? Let's get to work!
How It’s Done
Samples That May be Collected at a Crime Scene
A wide variety of physical evidence can be collected at a scene that is deemed valuable (“probative”) for collection and investigation:
-biological evidence (e.g., blood, body fluids, hair and other tissues)
-latent print evidence (e.g., fingerprints, palm prints, foot prints)
-footwear and tire track evidence
-trace evidence (e.g., fibers, soil, vegetation, glass fragments)
-digital evidence (e.g., cell phone records, Internet logs, email messages)
-tool and tool mark evidence
-drug evidence
-firearm evidence
Also included:
-Who Examines Crime Scenes
-How a Crime Scene Investigation is Conducted
-How and Where Tests on the Evidence are Conducted
Crime Scene features fictional crime cases in a unique combination of interactive fiction and gaming.
Each week, Yoknapatawpha County detectives post evidence from the current case.
You are invited to participate in the investigation by reviewing the presented evidence and offering your theories and questions to the detectives and other web sleuths.
The following simulated crime scene is designed to test your observation and knowledge. Observe each image and respond only to the questions associated with each image.
Developed for third grade. Students observe a crystal growth process.Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a college-level course on the teaching of biology at the elementary level. Unless otherwise noted, the lesson plans have been tried at least once by students from our partner schools. This wiki has been established to share ideas about teaching biology in elementary schools. The motivation behind the creation of this page is twofold: 1. to provide an outlet for the teaching ideas of a group of college educators participating in a workshop-style course; 2. to provide a space where anyone else interested in this topic can place their ideas.
Students learn about biomedical engineering while designing, building and testing prototype surgical tools to treat cancer. Students also learn that if cancer cells are not removed quickly enough during testing, a cancerous tumor may grow exponentially and become more challenging to eliminate. Students practice iterative design as they improve their surgical tools during the activity.
