Kitchen Science is a collection of activities that people can do at home, with everyday ingredients available from the supermarket or chemist. We want to show that science does not have to be done in a laboratory, by people in white coats. Instead, science is involved in all aspects of people’s lives.
There are some basic chemistry projects that are perfect for kids and Anne Marie Helmenstine has a great list of favourites from lava-filled volcanoes to liquid nitrogen ice cream to slime. Make sure to read the directions first, as some activities will require special ingredients and/or the help of an adult.
No list of science sites for children would be complete without a link to Bill Nye, the Science Guy. His website helps reinforce the lessons learned on his television show with experiments, explanations and a dose of humour as well.
How Stuff Works covers all sorts of interesting topics, but the science section includes space, earth science, life science and even paranormal science. Explore tornadoes, hair coloring, UFOs, radar and lunar landings. The site is geared more towards older audiences—the explanations may be too complex for younger kids—but it is a great resource for families.
This website educates students on science-related topics in the news. News items—such as the decline of the population of honeybees and how forensic science is used to solve crimes—are explained with kids in mind.
There are degrees of slothfulness, even when it comes to sloths. And three-toed sloths may be the most slothful of all, new data show.
Researchers studied two species of sloth in Costa Rica. They measured the rate at which these animals’ bodies operate, converting food to fuel and growth. And this metabolic rate in one species of three-toed sloth was the lowest ever recorded — not just for a sloth, but for any mammal.
The Sun is the star at the centre of our Solar System and it affects our lives every day in lots of different ways. Clink on the links below to find out more about our Sun and see pictures taken from NASA's Solar Dynamics Observatory.
