This gives kids an alternative way of adding if they have trouble with 'carrying'. It is also faster and more accurate for MOST kids.

### Microfinance for Kids - www.OneHen.org

by Christina Riechers

www.OneHen.org is a microfinance website for kids, with fun games and a virtual market, as well as lesson plans for teachers and librarians. The website is based on a children's book about a real boy in Africa who gets a loan to buy a hen, which over time turns into a thriving business - all because of a small loan to buy one brown hen. On the website kids can read the story, and read and see pictures and videos of real microentrepreneurs around the world in countries like Ghana, Brazil, Mexico and even immigrants in the U.S., and play games such as memory. Kids can donate "beads" won from the games to actual microentrepreneurs in developing countries through the virtual market, and as kids contribute they will see virtual businesses grow before their eyes. It's a beautifully designed website that aims to inspire good in kids while providing entertainment, and has great materials for teachers to teach their kids about topics ranging from world geography to community service to African culture to math to economics to business to global citizenship.

### Buoyancy Science Kit

by Cattaraugus Allegany BOCES Math Science Technology Dept

This unit provides students with the opportunity to observe the phenomena of buoyancy. Students will engage in inquiry about why some things sink and some things float. Students will explore properties of materials. Students will plan and construct their own floating containers from clay and compare it to containers already constructed. Students will experiment with their boats and the concept of displacement. Students will also measure the buoyant force in water using fishing bobbers and a rubber band scale that they construct out of K’nex. The science skills emphasized in Buoyancy are collecting data, manipulating, observing, and predicting. This collection is available as downloadable PDFs, but portions of the content are found in wiki format (see WIKI Learning Experiences and Resources) which can be edited or built up with other materials on the same topic by members of the Curriki community. More About CABOCES Welcome to the Math, Science, and Technology Department (MST) of Cattaraugus Allegany Board of Cooperative Educational Services (CA BOCES). As a department of Instructional Support Services (ISS), we provide Math, Science, and Technology kits along with support services to meet the needs of the individual districts in our area. The BOCES Teaching and Learning Center at Allegany provides hands-on math, science, and technology kits to over twenty area school districts in Cattaraugus and Allegany counties. Our department provides forty-three different varieties of kit topics. The kits cover topics in math, life science, physical science, chemistry, and earth science. Each kit contains a teacher's manual, student activity book, materials inventory list, instructional video, and materials needed to complete each learning experience.

### The Real Sponge Bob!

by Deal S

TEACHER PAGE INTRODUCTION: This lesson was developed by future teachers as part of the Educational Technology class at West Chester University in West Chester Pennsylvania. The goal of this lesson is to introduce students to the different types of creatures in the ocean and to help them realize that their are many different species of each type of animal. This lessons main idea is for the students to learn more about marine life. It teaches the students about different forms of marine life living in the sea and the different animals within those categories. There are a couple of different tasks the students will be performing. They will be using the websites provided to research the animal that they have chosen form there characters list. Then once they have found the information they need they will be writing a book on tikatock.com. Each group is to write one book. The multiple intelligences that will be addressed are visual and auditory.Visual will be addressed by viewing the episode of Spongebob along with a teacher instructed lesson and student research. Auditory requirements will be met also through the Spongebob episode and the teacher's lesson. Ultimately the presentation of students completed books will address visual and auditory learning as well. LEARNER: This lesson can be directed toward students in 3rdand 4th grade science and writing classes. Students will need to have a basic understand of the Spongebob Squarepants show as well as a basic understand of marine animal life and the basic workings of a story.

### The Earth, Sun and Moon: Investigations for the Third Grade

by Kenan Fellows

The following is a set of suggested activities for a third grade curriculum unit on the Earth/Sun/Moon system. The goal is to provide students with an understanding of the motions of the three objects in the system and the way in which they determine the periodic changes we observe. In particular, students should develop an understanding of the way the Earth's daily rotation determines the cycle of light and dark that we call day and night; the way the Moon's motion about Earth determines the monthly cycle of lunar phases; and the way the Earth's orbital motion around the Sun determines the annual cycle of seasons. We also discuss how eclipses - solar as well as lunar - come about. The cyclic changes we discuss are a visible and essential part of students' experience. In finding that they can systematically state, quantify, and model these changes, and that they can furthermore comprehend the astronomical phenomena that underlie them, students acquire not only a familiarity with scientific methods and facts but also a sense that these methods render the physical universe they inhabit essentially comprehensible. This in itself is an important aspect of teaching the unit, and we have attempted to structure the activities to make it explicit. The activities are constructed to fulfill the requirements of the North Carolina Standard Course of Study objectives for third grade science. Included in these is an understanding of some aspects of the nature of Light. Several of the activities address this - they occur early in the Unit, as the facts about light are used extensively in the following Activities. As a study of light this is woefully incomplete; some related enrichment activities are included for teachers interested in taking this to slightly greater depth.

### The Weather Man is Always Wrong!

by Melanie Rosenberg

This lesson idea came from the two of us thinking about what we could do a lesson plan on. We sat and thought about it and we came up with the idea of weather since it affects us every day. We thought this would be an interesting topic to do a lesson on because children really aren't aware of how much weather really effects them and how different the weather is around the country. The lesson is about the weather around the country. The children will be researching what the weather is like in the country that they live in. They will be in a group of four and they will each research the weather in a different city around the country. They will each come up with a weather report and then they will come together as a group and make a poster that reports on the weather around the country. Then will then report their findings to the rest of the class. The intelligences that will be addressed during this project are linguistic, spatial, interpersonal, intrapersonal, and naturalist intelligences. Linguistic intelligence is used during the research part of this project. The students will be looking at different websites to understand their location's climate and weather. Spatial intelligence is used when the students are looking at the map of the United States and deciphering between the east coast, west coast, mid-east, and mid-west regions. Interpersonal intelligence will be used when the groups pull together to form their weather cast. They will need to work together to collaborate and create their weather casts that represent the four regions of the United States. Intrapersonal intelligence is used after they present their weather cast to the class. They can reflect on their performance of their weather cast presentation and self critque. Lastly, naturalist intelligence is used as the students learn about their environment and the surrounding areas. The cognitive analysis levels that will be addressed during this project are analyze, explain, focus, prioritize, and select. These levels will be addressed while finding the most useful information during research. The cognitive synthesis levels that will be addressed during this project are generalize, plan, collaborate, compile, design, and structure. These levels will be used while the students are working in their groups to compose their weather casts.
