Aquí trobareu 5 activitats que formen part d'una unitat didàctica que gira en voltant del traç. L'objectiu principal és treballar des del traç fins al grafisme, incidint en la direccionalitat, la precisió, la coordinació ull-mà amb la finalitat de preparar als infants per la lectoescriptura, ja que és el pas previ adequat al nivell dels infants des de P3 fins a P5. Per poder aconseguir això, totes les activitats estan relacionades amb els animals, ja que és un tema que interessa i motiva molt a l'alumnat.

In this activity, students will record a list of things they already know about hummingbirds and a list of things they would like to learn about hummingbirds. Then they will conduct research to find answers to their questions. Using their new knowledge, each student will make a hummingbird out of art supplies. Finally, using their hummingbirds as props, the students will play charades to test each other in their knowledge of the ruby-throated hummingbirds. The purpose of this activity is to provide students with information on ruby-throated hummingbirds, provide students with the opportunity to conduct research on hummingbirds in topic areas that interest them, and to provide students with opportunities to share their knowledge with other students. By completing this activity, students will gain knowledge about ruby-throated hummingbirds. They will also gain experience researching a topic of their choosing related to hummingbirds and communicating those results in several different formats.

Students experience the excitement of watching live-streaming video of wild bears on Brooks River in Katmai National Park, Alaska, in order to explore science concepts in the real world. These three lessons, designed for grades 3–5, offer students the opportunity to engage in activities that focus in particular on the inheritance and variation of brown bear traits.

Using life-sized photographs, students participate in environmental monitoring of rocky intertidal and subtidal organisms.

Each student team researches and reports on one of the National Marine Sanctuaries and completes a thought-provoking worksheet to compare and contrast their sanctuary with the others.

In this lesson, students will use segments from Nature: Wild Balkans to explore the roles and interrelationships of organisms in the varied environments of the Balkan Peninsula. In the Introductory Activity, students will identify the Balkan Peninsula on a map and hypothesize what natural environments and wildlife might be present there. Students will use an interactive map to identify different regions of the Balkan Peninsula and the wildlife that resides in each region. In the Learning Activity, students will explore the regions of the Balkan Peninsula in more depth by viewing and discussing segments from the episode. Students will explore the habitats and wildlife of each region and the ways in which species collaborate and compete, as well as the role of humans in these environments. In the Culminating Activity, students will explore one species in depth and create a 3-D diorama or computer-generated simulation of the species in its environment. Students will discuss their projects with the class.

Once the pride of the German Navy, this 700 foot long heavy cruiser was used by the U.S. as a test target for not one but two atom bombs at Bikini atoll. Today, at the bottom of the ocean, the radiation levels of the Prinz Eugen are low enough for safe exploration. In this video, Jonathan joins historian Mark Miller on a trip to explore this mysterious shipwreck. What they find about the condition of this wreck is surprising. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

This Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here they meet Deena Soris, who interviews the fossil of a Protoceratops. The more-than-20 questions answered by this dinosaur fossil include: You look fabulous. How old are you?How do scientists guess an extinct dinosaur's speed?Is it a thrill to have a frill?So what happened?One day you're happily munching away on thick, tough plants, the next you're history?How did you go from being a "Gobi sandwich" to becoming a fossil?Your bones were underground for 80 million years. How did the paleontologists find you?Once you got to the Museum, what happened? Are there any secrets you'd like to share with the folks at home?
