This study guide summarizes key points about how sedimentary rocks are classified. Includes a few questions to check for understanding.

Kevin and his grandfather, Omag are going to the zoo. Join them and learn all about animal classification and life cycles.

This short lesson was designed in collaboration with a 7th grade Life Science teacher (Paul Jeffery). The idea behind the lesson is to help students better understand ecological and geographical classifications by teaching them at the same time in their Life Science class and their Geography class. Teaching the two classifications together will help reinforce the idea of classification. While this lesson would best be taught outdoors it can also be adapted to the indoors.

This collection of publications about genetics includes a unique approach to illustrate a genetics timeline. Important genetic events are correlated with other historical events. The book format allows you to scroll through history.

Video describing four types of angles - right, acute, obtuse and straight. [1:19]

A laboratory experiment where students classify matter into a homogenous mixture, heterogeneous mixture, solution, or pure substance. Also students will test for physical and chemical changes.

Introduction to the characteristics found in different animals and using the book: Feathers and hair, what animals wearAuthor:Jennifer Ward; Jing Jing Tsong

This concept teaches students to classify quadrilaterals in the coordinate plane.

In this video from Cyberchase, Bianca breaks her friend's tabletop when she's practicing dance moves in his living room. She uses measurement and geometry to get a new piece of wood that will fit the table exactly. The accompanying classroom activity helps students advance their understanding of perimeter and area by creating their own tabletop designs.

A pest is any organism that is unwanted or causes harm. How might we use these pest species to find out if they have any beneficial traits, such as antibacterial or antimicrobial properties? Students will learn techniques that allow a closer inspection of the microbiomes of insects in order to look for bacterial resistance and natural antimicrobial properties. This unit features 3 lessons and 10 files. Lessons are aligned to NGSS.

This video lesson introduces students to the concept of size. It looks at how to classify objects based on their size and how the size of an object affects its properties and behavior. In our world, we have many different sizes - starting from quarks and subatomic particles, to atoms and molecules, all the way to aggregates and huge objects like ourselves, and beyond to larger bodies like mountains, planets, stars, galaxies and even to the whole universe.

This activity is a field investigation or bio-blitz where students are collecting as many different types of insects as they can. Back in the lab, they will record their findings, sort and classify the insects found. This will lead into a class discussion on biodiversity and the importance of insects and their benefits all living things.

In the following video you will learn how classification is a continually evolving scientific effort to group organisms based on knowledge gathered from different fields. You will also learn how it helps to define the relationships among organisms and between organisms and their environments. [12:01]

This activity is a lab where students learn to classify objects that are similar into groups and technically describe their classifications. Introduction to dichotomous keys.

Organisms are divided into each of five kingdoms based on defining characteristics. Learn about the classification kingdoms and the placement of organisms within them. [1:14:02]

This activity is an inquiry and field study based. Students will be trying to observe, document, compare, contrast, and communicate what information they were able to gather. The will use this information to make in inference about the organisms they have found and classify them as either an insect or not an insect.

Students will investigate the organization of all living things through and learn how to classify through process of classifying their own shoes. Students will complete the classification of a Jaguar and write their own pneumonic device to remember the order of biological classification. (kingdom, phylum, class, order, family, genus, species)

This activity is an interactive game that helps students learn that vertebrates are classified into five groups and that each group has common characteristics that distinguish the animal group from other respective groups.

This activity is a field collection investigation where students gather earth materials and make observations about their collection that leads them to discuss the nature of Earth surface and how it is changing.

This activity is a field investigation where students use a dichotomous key to properly identify trees in our schools nature center.
