What is sugar?
This reading, part of a site about the science of cooking, provides general scientific information about sucrose (white table sugar) together with explanations of the science behind some candy-making procedures. The general information includes the chemical formula of sucrose and a ball-and-stick model that illustrates that sucrose is made of fructose and glucose. Regarding candy, the reading describes how heating a sugar solution produces a supersaturated solution. A discussion about common tec
What's a quick way to unroll a roll of toilet paper? This material is part of a series of hands-on science activities designed to arouse student interest. Here students use Bernoulli's principle and an electric leaf blower to force air over the top of the toilet paper to quickly unroll it. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of applicable K-12 national science education standards. Also provided are c
PBS provides students in grades 4-7 with oodles of science fair ideas and a science fair tip sheet in this section of the DragonflyTV web site. Overviews of investigations from the television show are offered to help students hone in on an interesting topic and create their own science fair project. Each overview relays a question that a child asked on television, the main steps in his or her experiment, and the results. The overviews also include ideas for further investigations that build on t
Quick take on those dicey decimals!
Understanding decimals is a must and practice with them a basic necessity. These digital resources feature games, lessons, and interactive experiences that encourage understanding and practice at varying levels of mastery.
This is a simple activity to visualize a communication system. In order to do this the students encode, decode, transmit, receive and store messages. They will use a code sheet and flashlight for this process. They will also maintain a storage sheet from which they can retrieve information as and when it is required.
Quick take on safety in the science classroom
With the increasing emphasis on hands-on instruction, it becomes more important than ever before for science teachers to be knowledgeable about laboratory safety issues. The National Science Education Standards say that students should have frequent opportunities to use a wide range of equipment, materials, supplies, and other resources for experimentation and direct investigation of phenomena. The National Science Teachers Association recommends that a minimum of 80 percent of science instructi
Help the immune system fight off an infection in this interactive feature from the NOVA: Surviving AIDS Web site.
This collection of images shows several types of plant seeds, each with a different mechanism for dispersing from the parent plant.
Racing Game with One Die

Science in Focus: Shedding Light on Science: Workshop 5. Sunlight to Starch
Explains the process of photosynthesis. Leaves from plants grown in the light contain starch, but leaves from plants grown in the dark do not contain starch.
Skulls : structure and function
Skulls have been designed for both form and function. Through the use of text and labeled photographs, this website explains how specific skull adaptations meet the needs of organisms. For instance, visitors will discover that some beaks of macaws are attached to their skull only through ligaments to limit the amount of force put on the skull when the birds crack open nuts. The site also presents a series of skull facts, questions, and answers provided by scientists. A unique feature allows visi
Lessons on the Lake : An Educators Guide to the Ponchartrain Basin
This resource is designed to educate students, through activities teachers can use, about the environmental importance of Lake Ponchartrain. The main goal is to foster a sense of stewardship in students through learning to identify environmental issues that affect the lake, offer changes, and develop solutions. Although the resource deals with the Lake Ponchartrain Basin, the activities are applicable to students and teachers beyond this local level. The activities and lesson plans cover everyth
Improving Mathematics Education: Resources for Decision Making
This report has been designed to help inform stakeholders about the decisions they face, to point to recent research findings, and to provide access to the most recent thinking of experts on issues of national concern in mathematics education. The essence of the report is that information is available to help those charged with improving student achievement in mathematics. It can guide those who make decisions about content, learning, teaching, and assessment. Eight important documents were revi
Science Sampler : Thinking about students' questions
Asking questions is a vital component in any classroom, but it is absolutely essential in a science classroom. As science teachers, we know that questioning plays a major role in the inquiry process and has a positive impact on students' learning. This article discusses the importance of questioning skills and current research on questioning techniques. In addition, this article will present a series of lessons that were implemented by the author to improve the questioning abilities of middle sc
Virtual Polyhedra and the Real World
Using computer models, paper, cardboard, wood, and other media, students study and construct three-dimensional polyhedra. Students will learn to identify the platonic polyhedra (tetrahedron, cube, octahedron, dodecahedron, and icosohedron). Students will also learn to describe complex geometric solids in terms of vertices, edges, and faces.
This interactive planetarium can create sky maps for a given location and a given time. Once the latitude and longitude of the desired area is entered, the Web site creates a map of the sky. The names of cities can be entered in place of longitude and latitude.
