This fabulous collection of interactives and tools supports math and science concepts across grades 3-12. There are also lessons to accompany the activities and a dictionary of math terms. Sort by "audience" to narrow the listings by level: 3-5, 6-8, or 9-12. Version 3.0, released in 2010, provides better searching by activity type and curriculum term. Click at the bottom of the screen for an "interactivate Guide" to explain the various ways you can search, or simply click on Learner Activities to browse and see the breadth of offerings in areas such as Number and Operations, Geometry, Algebra, Probability, Statistics, Modeling, Discrete, and more.

tag(s): numbers (119), operations (71)

In the Classroom

Mark this one in your teacher favorites, then return to select activities in support of math or science units. Many curriculum topics have multiple offerings, so let students choose from among three to five activities for homework, in-class practice, or student- demonstrated skills on an interactive whiteboard or projector. Rotate different student groups to run the demonstrations and explanations of the interactives or have them write explanations of them on a class wiki for others to use for review and practice.

- Grades 9-12 - This unit is based on the debate over damming the Hetch Hetchy Valley in Yosemite National Park, which helped mark the evolution of the conservation movement. The unit has two parts: the first details conservation through the rationales of various historical figures, and the second outlines the case study of Hetch Hetchy. The format of the second part includes a mock hearing where students present their researched ideas. In the course of the unit, students will also compare historical ideas of conservation with current ones.

tag(s): conservation (86), ecology (99), environment (238)

In the Classroom

Be sure help your weaker readers and ESL students by sharing the vocabulary words prior to reading, either on a handout or by projecting on an interactive whiteboard and highlighting them in the text as you come to them.

The EPA created this collection of resources dealing with water cycles, water purification, and water availability. It includes web resources, sample experiments, and explanations of water quality issues. Each topic has several areas to explore and learn from.

tag(s): agriculture (48), conservation (86), ecosystems (73), environment (238), water (101)

In the Classroom

Start with Water Basics, and find lots of topics and activities. Review the water cycle on your interactive whiteboard or with a projector. Engage your students with one of the interactive activities. Once your students have the basics, enhance learning by having them choose a topic as a source for a multimedia project to present what they learned using Genially, reviewed here. With Genially students can insert maps, surveys, video, audio and more. Teachers will likely want to sort through the material before suggesting it to their students.

This site from the Museum of Natural History is a rich resource for images of dinosaurs. You can select by body type, country, geologic time period, and other idicies. Apart from the images, which are watermarked, there is only basic information on the size and environment of each creature on the landing page, however, scroll WAY down to the bottom of the page for a site menu. Look for Discover, and under that Dinosaurs. On this page you will find a WEALTH of information from an Introduction to Dinosaurs to Dinosaur behavior, abilities, lifestyles, to Dinosaur Digs, and even Dinosaur Crafts and Activities. While not intended for elementary students, the navigation is simple enough for these students to use effectively in finding images.

tag(s): dinosaurs (39), reptiles (12)

In the Classroom

In a unit on dinosaurs, share this site on an interactive whiteboard or projector with students. The function they will find most interesting about this site is the area that describes the dinosaurs that existed in their local area! Brief bios are presented on all the dinosaurs, so this could also be a great resource if the students were to research their local dinosaurs for a project.

MendelWeb is a rich hypermedia site that integrates the study of elementary mathematics (i.e. probability and statistics), classical genetics, European history, and the history of early modern biology. It is geared to both the high school/AP teacher and student. The section entitled "Secondary Sources and Tools" provides additional ideas and activities for use in the classroom. Noteworthy is the "Mendelroom" a virtual space designed for teachers and students who wish to share their experiences and ideas when using MendelWeb.

tag(s): genetics (76), probability (96), statistics (116)

In the Classroom

Introduce this site with a projector or on an interactive whiteboard to show students how to navigate. Suggestion - start with "Experiments in Plant Hybridization." The English Hypertext is a glossary. Then, in your flipped or blended classroom (or at a computer center), have students explore assigned sections of Experiments in Plant Hybridization on their own. Ask students to create their own concept maps sharing their learning and understanding using MindMup, reviewed here. Take this a step further and allow pairs or small groups of students share what they learned with their peers using an interactive infographic like Canva, reviewed here. Students can keep their work for future reference in a digital portfolio such as DIY, reviewed here. If your students are already familiar with the content of "Experiments in Plant Hybridization," use the tool suggestions as above for the "Secondary Sources and Tools" section.

This site from the U.S. Department of Energy describes the origins and goals of the Human Genome Project, as well as the reasons for DOE's involvement. It offers a literate, sometimes challenging introduction to the effort to map the entire human genetic code. Apart from its obvious use for report research, the site could also serve as an introduction to genetics, cloning, or other aspects of high-tech biology.

tag(s): dna (44), genetics (76)

In the Classroom

The reading here is both dense and full of high-level vocabulary that almost limit its usage to that of an AP classroom. However, if your readers are able, this could be used in a class debate or discussion about current events in high-tech biology. You can always use a tool like Professor Word, reviewed here, which is a bookmarklet you use to highlight any word on the page to see it's definition.

Though this site has been archived, the contents remain timeless and useful in many settings. BBC's Flash-enabled tour of the human body couples nice animations with relatively detailed descriptions of the major organs and body systems. The texts explain the roles of each body part in maintaining digestion, respiration, circulation, and overall body metabolism. There are also limited links to external information sources. The animations do a particularly good job of showing "how all the parts fit together."

tag(s): body systems (40), respiration (10)

In the Classroom

Introduce this activity with a projector or on an interactive whiteboard to show students how to navigate the site. Then, in your flipped or blended classroom (or at a computer center), have students explore on their own. Ask students to create their own concept maps sharing their learning and understanding using MindMup, reviewed here.

From the "Ask a Biologist" series at Arizona State University, this site provides a concise, well illustrated description of how your eyes perceive colors. Easy to use and nicely organized, it's one of several simplified biology resources available from this site.

tag(s): colors (64), eyes (5), vision (45)

In the Classroom

The text portions may be challenging, so you should pair weaker readers with a partner as they read. Have students take notes on the material and write down questions they still have and topics that confuse them. They can do this with pen and paper or online. If you want the assignment online, explain to students they need to open a new tab in their browser window and take notes with a tool such as Webnote, reviewed here; tell students to be sure to save the URL to share their notes and questions with you and their peers. At the bottom of the page there are several topics labeled Read More About Seeing Color. Divide students into small groups to research and take notes for one or more of the topics. Then ask students to share what they learned by creating a simple infographic sharing their knowledge about seeing color using Visme, reviewed here.

tag(s): animals (283), cells (81), plants (146)

In the Classroom

This site will compliment your study of cells. Use it as an introduction or review. Share this site on your interactive whiteboard or projector. Have students explore this site independently or in pairs. If used independently put the site on a classroom computer and use as a center. To use in pairs, bring students to the lab or use a classroom set of laptops. This site would also be a good one to add to your class webpage or blog for use at home. Have students create a simple infographic sharing their findings using Visme, reviewed here.

What a find! Chem4 Kids contains six sections ranging from Matter, to Math in Chemistry, and Chemical Reactions. Information on each topic is presented clearly. Hyperlinks are included to assist students in understanding terms.

tag(s): atoms (42), chemicals (39), elements (32), matter (46), periodic table (44)

In the Classroom

The explanations are clear and concise and the examples are everyday items. Students should create their own flashcards or work together as partners or in small groups to create flashcards for each section. Each topic and term has what looks like hand-drawn images for examples. Where possible challenge students to draw their own examples. Students could use Padlet, reviewed here, to brainstorm a list of examples (images) to replace the ones Chem4kids has for their flashcards. Next, have students create the drawings using Draw.Chat, reviewed here. Have students save their drawing(s) to their computer, or if you are cloud based save it there, to add to student made flashcards. Use a flashcard tool such as Flashcard Stash, reviewed here. Ask students to think about replacing the image examples used on Chem4kids to help them to understand the topic, and drawing their own replacement examples will help them remember the information. Then use and image annotation tool like Phrase.it, reviewed here, to explain their replacement.
