This lesson discusses important limits of particular sequences that can be very "useful in many branches of science." Includes good proofs.

Take a closer look into the modern view of evolution. This article includes many pieces of evidence, all which support the theory of evolution.

A multiple-choice quiz on the mechanisms of evolution.

India Parenting takes a look at why "I?m creative and he?s analytical" with a discussion of right brain and left brain characteristics.

Jamie McKenzie's book, Beyond Technology: Questioning, Research and the Information Literate School, emphasizes the need to teach children to ask important questions, then research the answers, instead of just learning information...

This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

This lesson plan involves comparison of amino acids to create a phylogenetic tree of primates. Students will also use other species information to draw conclusions about evolutionary relationships.

Read a brief, but clear description of the three evolutionary processes that occur in species over time.

Learners identify plate boundaries as well as continents, countries, and bodies of water to become familiar with an area known as the "Ring of Fire."

Listen to this podcast which explains the basics of plate tectonics on Earth. [0:39]

Visit this site to learn more about the different types of plate boundaries. Includes color pictures and easy-to-understand examples of how and why plates move the way they do.

Constructing phylogenetic trees may be a daunting task for students, but this lesson plan is a simulation of what molecular biologists must do to determine relationships. This plan is for students who have a good grasp of DNA structure...

What exactly is a "questioning tool kit"? This resource provides techniques for asking essential questions, hypothetical questions, telling questions, planning questions and organizing questions.

Illustrated diagrams in this tutorial help students understand the properties and functions of lenses.

Students take an in-depth look at the physics behind image formation.

Explains what a transform boundary is and gives examples of well-known faults of this type.

Lenses are precisely shaped pieces of glass that have been developed and used in corrective glasses, telescopes, microscopes, binoculars, and magnifying glasses. They can be convex or concave. Links are provided to a video an a test.

A detailed discussion of plate tectonics. Looks at continental drift, types of tectonic plates and plate boundaries, and primary and secondary tectonic plates.

An easy-to-understand explanation of what plate tectonics is. Contains information about the inner parts of the Earth, the difference between the three types of plates, and numerous maps and illustrations.

[Free Registration/Login may be required to access all resource tools.] Discusses what a tectonic plate is and how scientists can recognize its edges, how the plates move by convection in the mantle, the three types of plate boundaries...

As teachers, we play an important role in supporting children's ability in art, dramatic expression, and creative responses to problems. Creative power increases a young child's desire to learn and supports intellectual development. This...

This comprehensive study guide covers the main terms and concepts needed for an earth science unit on the earth's tectonic plates. Review questions are included at the bottom of the study guide.
