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.

We often use our phones or other devices without even thinking about it. But paying closer attention to how -- and how much -- we use digital media can help us find better balance in our lives. Challenge students to truly consider how digital media adds to -- or takes away from -- their overall quality of life.

My Math GPS: Elementary Algebra Guided Problem Solving is a textbook that aligns to the CUNY Elementary Algebra Learning Objectives that are tested on the CUNY Elementary Algebra Final Exam (CEAFE). This book contextualizes arithmetic skills into Elementary Algebra content using a problem-solving pedagogy. Classroom assessments and online homework are available from the authors.

Students are introduced to various types of hearing impairments and the types of biomedical devices that engineers have designed to aid people with this physical disability.

We all make choices every day about the media we consume and create. But do kids understand what makes a media choice healthy or not? Hint: It's about more than just screen time. Use the activities in this lesson to give kids a framework for making informed media choices.

Most of us use a lot of digital media in our daily lives -- even when we don't realize it! Having a balance between online and offline time is important, but healthy media balance might look different for everyone. Help students create a personalized plan for healthy media use.

Students are introduced to the futuristic concept of the moon as a place people can inhabit. They brainstorm what people would need to live on the moon and then design a fantastic Moon colony and decide how to power it. Students use the engineering design process, which includes researching various types of energy sources and evaluating which would be best for their moon colonies.

For most middle schoolers, being on social media can mean connecting with friends, sharing pictures, and keeping up-to-date. But it can also mean big-time distractions, social pressures, and more. Help students navigate the different feelings they may already be experiencing on social media.

Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.

Uses primary sources to explore the impacts World War I had on the struggle for civil rights in Connecticut and America.

This are history video discussion with Beth Harris and Steven Zucker looks at Myron of Eleutherae's "Discobolus (Discus Thrower)", Roman marble copy of an ancient Greek bronze, c. 450 B.C.E. (Palazzo Massimo alle Terme, Rome).

Kindergarten students are encouraged to gain an increased awareness of themselves and the world around them in our entry level text in the series.

This lesson will explore the connections between magnetism in natural materials and electromagnetism. The ultimate goal will be for students to form an understanding that the source of magnetism in natural materials is moving charges. It is helpful, but not required, for the students to have some work with electricity, and other distance forces (such as gravity or the electric force). The lesson will probably take two 50-minute periods to complete. Although the video footage is brief, the activities are in depth, inquiry-based, and can take time for the students to explore. The materials are not specifically prescribed, but can include things such as bar magnets, compasses, iron filings, wire, batteries, steel bolts, coils, straws, and hot glue. The activities include drawing the magnetic fields of bar magnets and electromagnets. The activities also include making a magnet from a drinking straw and iron filings.

In this video lesson, the concept of momentum applied to hard-body collisions is explained using a number of simple demonstrations, all of which can be repeated in the classroom. Understanding Newton's Laws is fundamental to all of physics, and this lesson introduces the vital concepts of momentum and energy, and their conservation. Only some preliminary ideas of algebra are used here, and all the concepts presented can be found in any high-school level physics book. In terms of materials required, getting hold of large steel balls may not be easy, but large ball bearings can be procured easily. On the basis of what students have learned in the video, teachers can easily generate a large number of questions that relate to one's daily experiences, or which pose new challenges: for example, in a collision between a heavy and light vehicle, why do those inside the lighter one suffer less injury?

How people make sense of their worlds symbolically through myth, ritual, metaphor, and cosmology. The structure of symbols, the natural and social elements they draw on, their social use, and the messages they convey. Students learn to record and analyze myth and ritual.

This online textbook contains short articles on each major deity, hero, monster, etc., in Greek mythology. The text is supplemented with color photographs and maps to enhance the learning experience.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Renee reasons as follows to solve the equation $x^2 + x + 1 = 0$. First I will rewrite this as a square plus some number. x^2 + x + 1 = \left(x+\frac{1...
