Online resources present a multitude of opportunities for students to learn essential science concepts in an interactive and dynamic environment. Three of the most exciting and potentially beneficial online applications currently available include image processing tools, simulations, and interactive outreach projects which involve students and scientists from across the globe.
Image Processing
Image processing involves examining and working with images to learn more about what they represent. Consider, for example, how a detailed, real-time view of a hurricane could be used to enhance meteorology instruction. By enhancing, manipulating, or even animating this image, students can investigate and collect measurable data about variables including size, speed, distance, and storm track. Are students learning about global climatic change? Images that illustrate the extent of snow and ice coverage over given areas can help students understand meteorology on a more global scale.
This type of online tool makes possible a ground-breaking instructional shift. Not only is the equipment to obtain these types of images first-hand unavailable in most schools, but the opportunity to view them in real time is nonexistent without the Web. Compare these advantages with studying static images from print material alone, and the difference is staggering.
Consider the following Web sites as you search for applicable image processing tools and images.
Simulations
Virtual experiments cannot replace traditional laboratory experiences. However, some interesting and relevant questions are difficult or even impossible to investigate in the traditional laboratory setting. For example, studying the changes in momentum and velocity which occur when a truck and car collide, is not viable in the classroom. Due to budgetary or other restrictions, even a frog dissection might not be possible in some schools. Simulations offer an interesting and often quite realistic way to examine content best acquired through hands-on experience.
There are many advantages to using online simulations. They can provide access to equipment not available in most classrooms, and can mimic the behavior of objects or situations which may be too dangerous, too large, or too small to be studied in the lab. In addition, students are often highly motivated by computer simulations, increasing the desire to learn and the capability for retention.
These resources for online simulations will prove helpful as you begin your search.
Interactive Outreach Projects
Scientists rarely work in isolation. Communication and collaboration with others conducting similar kinds of experimentation are crucial components of scientific study. A wide variety of projects are available online which allow students to interact and share data with other students and professionals worldwide. When students share questions, data, and conclusions with others, they achieve the sense of connection felt by all scientists doing research on specific topics. Additionally, becoming part of a large-scale project reinforces the concept that science is used to solve real problems.
The variety of free, online projects available is extraordinary. Students can become involved in projects ranging from comparisons of local ecosystems to measuring changes in the Earth's magnetic field to conservation of resources and investigation of endangered species. The following Web sites will prove helpful in selecting a project that is right for you and your students.
Making Connections
The sheer volume of available online tools for enhancing science instruction can make searching for the perfect tool a daunting task. Try not to be overwhelmed. Start by adding one simulation to an existing lesson, or perhaps let students experiment with a single image. As your confidence grows, so will your repertoire of technological tools. The more experience students gain in using online tools, the greater their understanding of the connections between science, technology, discovery, and communication will be.
