This interactive presentation on the classification of joints provides a great overview of the three types of joints and their functions.
A great overview of the science of classification. Topics addressed include summaries of the five kingdoms, the seven taxa, the definition of a species and the classification of the panda.
This lesson will introduce the systematic classification of matter used in chemistry, defining the terms heterogeneous, homogeneous, pure substance, mixture, compound, element and providing examples.
The topic of this video module is how to classify animals based on how closely related they are. The main learning objective is that students will learn how to make phylogenetic trees based on both physical characteristics and on DNA sequence. Students will also learn why the objective and quantitative nature of DNA sequencing is preferable when it come to classifying animals based on how closely related they are. [55:08]
In this activity students will observe and investigate rocks in order to classify them in terms of color, shape, texture and size.
This activity is a field investigation where students gather leaves from various trees on school property, interpret findings, name tree and leaves, journal activity and develop a new "aha" for nature!
In this Earth Science activity, students will investigate rocks in an outdoor field trip. Students will be divided into groups and given a Ziploc bag to collect rocks. We will then return to the classroom, and the students will put their rocks into different groups. The different groups could be the size, shape, color, and texture of the rocks. We will then talk about the Rock Cycle and the three main types of rocks. Students will record their observations in their science journals.
This article describes some common misconceptions that elementary students may have about plants. It also includes suggestions for formative assessment and teaching for conceptual change.
This article discusses misconceptions about birds (and penguins in particular). It provides tools for formative assessment and ideas for teaching correct scientific concepts.
Get the facts about cougars. Besides finding a detailed description of the cougar, you?ll also learn about some of its unique facts and characteristics. Also included in this Mammal Fact Sheet on cougars is information on their habitat and habits, range, feeding, breeding, and conservation efforts. Don?t forget to check out the video clips of cougars using the link near the top of the webpage. A list of resources completes the fact sheet.
This activity gives a visual representation of how we are able to see the different layers of metamorphic rocks.
This activity asks students to work in a team to develop a set of rules that can be used to program a SPAM filter for a client. The rules are based on characteristics of the subject lines of emails. Students are given samples of SPAM and non-SPAM subject lines to examine. After their rules are ready, they are given a test set of data to use and are asked to come up with a numerical measure to quantify how well their method (model) works. Each team writes a report describing how their model works and how well it performed on the test data. This activity could serve as an introduction to ideas of classification. Alternatively, the activity could be the basis for student introduction to types of statistical errors.
Get the facts about the Downy Woodpecker, eastern North America's most common woodpecker. Besides finding a detailed physical description of the smallest member of the woodpecker family, you?ll also learn about some of this bird's unique facts and characteristics. Also included in this Bird Fact Sheet on the Downy Woodpecker is information on its habitat and habits, range, feeding, breeding, and conservation efforts. A list of resources completes the fact sheet.
