Closing one eye eliminates one of the clues that your brain uses to judge depth. Trying to perform a simple task with one eye closed demonstrates how much you rely on your depth perception. In this activity, learners compare their ability to perform simple tasks with one eye versus with two eyes.

In this lesson designed to enhance literacy skills, students learn that transitional fossils provide scientists with evidence to establish how major animal groups are related to one another.

How is it that all cells in our body have the same genes, yet cells in different tissues express different genes? A basic notion in biology that most high school students fail to conceptualize is the fact that all cells in the animal or human body contain the same DNA, yet different cells in different tissues express, on the one hand, a set of common genes, and on the other, express another set of genes that vary depending on the type of tissue and the stage of development. In this video lesson, the student will be reminded that genes in a cell/tissue are expressed when certain conditions in the nucleus are met. Interestingly, the system utilized by the cell to ensure tissue specific gene expression is rather simple. Among other factors - all discussed fully in the lesson - the cells make use of a tiny scaffold known as the “Nuclear Matrix or Nucleo-Skeleton”. This video lesson spans 20 minutes and provides 5 exercises for students to work out in groups and in consultation with their classroom teacher. The entire duration of the video demonstration and exercises should take about 45-50 minutes, or equivalent to one classroom session. There are no supplies needed for students’ participation in the provided exercises. They will only need their notebooks and pens. However, the teacher may wish to emulate the demonstrations used in the video lesson by the presenter and in this case simple material can be used as those used in the video. These include play dough, pencils, rubber bands (to construct the nuclear matrix model), a tennis ball and 2-3 Meters worth of shoe laces. The students should be aware of basic information about DNA folding in the nucleus, DNA replication, gene transcription, translation and protein synthesis.

This informational text introduces students to the geographic uniqueness of the North and South Poles. The text is written at a grade four through grade five reading level. This is a PDF containing the informational text and a glossary.

This graphic from Biology by Kenneth R. Miller and Joseph Levine suggests how some recent hominid fossil finds might fit into the overall picture of hominid evolution. As more fossils are found and further analysis advances our understanding of human evolution, this picture will almost certainly be revised.

Animals are sometimes hard to see, but with observation skills we can use evidence to figure out where they‘ve been and what they’ve been doing. Students love to look for evidence of animals, and teaching them basic tracking skills can open up a world of intrigue and mystery. In this Focused Exploration activity, students use observation skills to notice evidence of animals living in the area. With a few basic tracking tools, students look for animal signs, and follow animal paths to new discoveries. Students also engage in key science practices as they share explanations for the animal signs they find, compare and evaluate explanations based on the strength of evidence, and take part in scientific argumentation.

This animation produced by WGBH and Digizyme, Inc. demonstrates the experimental technique used to introduce DNA plasmids inside bacterial cells, a process called bacterial transformation.

John Noble Wilford, a New York Times science writer, outlines various hypotheses on the origin of bipedalism.

In this video segment from NOVA: Judgment Day: Intelligent Design on Trial, learn about the discovery of a well-preserved transitional fossil and how such transitional fossils support the theory of evolution.

Understanding Biodiversity presents an overview of biodiversity, its importance and relevance to humans, all living things, and the Earth. It includes species pages and a template to engage and involve students in real-life data collection.

The environment plays a critical role in shaping the evolutionary changes that organisms undergo. For animals, food is one of the most important components of the environment. This video focuses on snakes and some of the most important adaptations of these remarkable creatures.

This video from Kentucky's Last Great Places shows how the Green River has remained unusually clean and why it is home to several endangered aquatic species.

This lab-based course covers the foundational principles of modern life science as outlined in the Next Generation Science Standards (NGSS). It also includes approximately a third of the Earth and Space Science standards, primarily those connected to environmental science and ecology. The course emphasizes all three dimensions of the NGSS, with special attention to the crosscutting concepts of Patterns and Energy and Matter. Additionally, scientific inquiry and engineering design practices are emphasized throughout the course. The course is designed to follow a chemistry course and so builds on student understandings of molecules as they explore the biomolecular underpinnings of life's functions, the evolution of life, and the interactions of life in ecosystems. Technological, historical, political, and environmental aspects of biology will also be addressed. Critical thinking, data analysis, and argumentation from evidence are also emphasized.

Anchoring Phenomenon: A baby is born and seems perfectly healthy, but after a few days starts to exhibit strange symptoms that could lead to physical impairment or even death. What is causing the problem? Can the baby be saved? Unit Essential Question: How and why do cells make the molecules they need and get rid of the molecules they don’t need? What happens if steps in this process aren’t working?

For this unit plan, see the old unit calendar (link on left sidebar, click ALT3 tab at the bottom).  Once we update this unit to the new Doc template, we will post it here. This is now unit 3, but it used to be unit 2 (we will update file and folder numbering as we continue to revise the units). Thanks for your patience as we work hard this year to update all of the materials to the new unit template and unit/standards arrangements.
