Smithsonian 10 Minute Science Experiments
From author, educator and television personality Steve Spangler
Steve Spangler is dedicated to finding the most creative ways to make science fun and interesting for kids. With more than 1,300 television appearances to his credit, Steve is a regular guest on The Ellen DeGeneres Show, where she dubbed him “America’s Science Teacher.”
Most experiments can be done in 10 minutes or less
Though most projects typically take no more than 10 minutes to conduct, the book includes a number of experiments that extend the learning over an entire weekend. Each experiment includes step-by-steps instructions and photos designed to maximize comprehension and enjoyment.
50 experiments that teach the basics of physics and chemistry for ages 7 – 11
Experiments range from the simple, yet surprising (Q: How many drops of water can fit on a penny? A: More than you’d imagine!) to the more complex and mind-blowing (Extract DNA from a strawberry – or build a working movie projector with a box, a magnifying glass and a mobile phone!).
Learn the scientific method and more
Readers will learn critical thinking skills as well as how to use the scientific method to understand even more about what’s happening during each activity. Intriguing sidebars and trivia tidbits keep kids learning even when they’re not working in the “lab.”
A Super-Cool Experiment: How to Freeze Water Instantly
Shove two plastic water bottles in a big bowl of ice
Keep the bottles close to the center of the bowl and buried in the ice as much as possible.
Grab some rock salt!
Scatter a generous amount of rock salt all over the surface of the ice.
Monitor the temperature
Insert a thermometer into the ice between the bottles. The temperature will fall slowly over the next half hour or so. Add more ice and salt to keep the bottles buried. Once the temperature reaches 17 degrees F, move on to the next step.
Instant freeze!
After the water has been this cold for 10 minutes, gently remove a bottle from the ice. Strike the bottom of the bottle sharply against the table and ice crystals should immediately form near the top of the bottle and quickly move down through the liquid, turning it into a solid mass of ice. Twist open the cap of the second bottle and the water will freeze from the bottom up.
