The National Zoo is home to 2,000 individual animals of nearly 400 different species. Our best known residents are our giant pandas, but great apes, big cats, Asian elephants, birds, amphibians, reptiles, insects, aquatic animals, small mammals, and many others can be found at the Zoo. You can take a virtual visit to the Zoo any day of the week by tuning into our live web cams, which feature many of the Zoo's animals.

Can't make it to a zoo? Observe animal habits and habitats using one of the many webcams broadcasting from zoos and aquariums around the United States and the world in this inquiry-based activity that focuses on observation logs, class discussion, questioning, and research. Students begin by viewing an animal webcam, making observations, and describing what they see in a notebook or log.

Students explore the genetic changes associated with lactose tolerance/intolerance and how the trait is inherited in families.

"The Progressive Achievement Tests in Science (PATScience) is a thoroughly researched and nationally normed test to assess student achievement in scientific understanding from Years 3 to 10. The test questions are designed to assess science knowledge, scientific literacy and understanding of scientific principles, as well as their application."

"This instructable will show you how to build a stand for about $10 that will transform your smartphone into a powerful digital microscope. This DIY conversion stand is more than capable of functioning in an actual laboratory setting. With magnification levels as high as 175x, plant cells and their nuclei are easily observed!  In addition to allowing the observation of cells, this setup also produces stunning macro photography."

"See three-dimensional planet models along the way as you shuttle from Pluto at the furthest reaches of the Solar System to the Sun, which is represented by the 37-metre Anglo-Australian Telescope dome at Siding Spring Observatory.  The planets are displayed on huge billboards with the size of the planets and the distance between each billboard scaled relative to the dome - the Sun - along the five main roads that lead to Coonabarabran in regional NSW."

"A list of Bronze CREST science and technology projects to provide inspiration for students wanting to try open-ended investigations."

"In this video, I show how to find the speed of a moving object, using distance and time. I've included one example to show how it works. Thanks. "

"For one thing, nine of the 10 hottest years on record have happened in the last decade. So I'll discuss just two facts - how carbon dioxide causes global warming, and where this heat is going."
