And the plants or animals you eat get their energy from other plants and animals, or from the Sun. All energy comes from somewhere. The award of a Nobel Prize in physics to Donna Strickland is an opportunity to build support for women in science, says one female physics professor. Donna Strickland is the first woman in 55 years to be awarded the Nobel Prize in Physics. Let's hope the next such award to a woman won't take so long. Using lasers to trap and move particles changed the way we're able to study microscopic life.

The way science is currently taught in southern African countries ignores the fact that the whole environment is a laboratory for learning. The new physics syllabus for year 11 and 12 students in NSW contains no mention of specific women who have contributed to the field, nor their work. Astronomers are voting to rename one of the laws of physics. Listen up. The Science of the Water Bottle Flip. Water Jelly Crystals. Balloon Skewer - The Lab.

Balancing Brooms - finding the centre of mass

What you Need What to do Point the index fingers of both hands and hold your hands apart but parrallel. Get someone to balance the broom horizontally on your two index fingers, making sure you keep them level. Now gently move your fingers together. What may happen You should find that as long as you keep your fingers level the broom stays balanced, even as they get very close together. Why does it happen? When you start off holding the broom inevitably one finger will be closer to the centre of mass than the other. This means that more of the weight will be sitting on the closer finger, so it must be pushing upwards harder.

Teaching with TLC: 10 ways to make physical science FUN!

I just love it when they are hooked on learning! My kids have been learning all about simple machines, matter, and electricity from the best science teachers at the Edison Home. What better place to learn about science than Edison's home! A big thank you to the wild wizards there! They did a super job setting the stage for further science lessons. As you may already know, I REALLY like hands-on learning because those are the lessons that make learning stick. We watched Bill Nye, The Science Guy teach about Atoms in this great video!

The kids used cereal to model the different spacing of atoms in matter. We made a 3-D atom using an orange, candy, and toothpicks. Bernouilli's Flying Toilet Paper and Floating Beach Balls. Physicists Achieve Quantum Teleportation of Photon Over 25 Kilometers. For the first time, a team of physicists have successfully teleported a quantum state of a photon to a crystal over 25 kilometers away through a fiber optic cable.

Physicists Achieve Quantum Teleportation of Photon Over 25 Kilometers

This effectively showed that the photon’s quantum state, not its composition, is important to the teleportation process. The team was led by Nicolas Gisin of the University of Geneva and the results were published in the journal Nature Photonics. With this new paper, Gisin’s team has successfully squashed the previous record they set a decade ago by teleporting a quantum state of a proton 6 kilometers. The quantum state of the photon is able to preserve information under extreme conditions, including the difference between traveling as light or becoming stored in the crystal like matter. The photon’s state acts as information that can be teleported along great distances using the optical fiber, and can be stored within the crystal.

Students work in teams to develop a system to make an insulated liquid container that will keep chilled water as cool as possible for an hour using everyday items. Students will need to devise a way to have a thermometer rest in the water and be able to read the temperature throughout the hour. They plan their design, execute and test their system and share their experiences with the class. Age Levels: Objectives Learn about insulation, heat transfer, and vacuums.Learn about engineering design and redesign.Learn how engineering can help solve society's challenges.Learn about teamwork and problem solving.
