Brian Cox school experiments: What factors affect the pitch and the volume of a sound?

(1)
The Brian Cox school experiments are designed to support teachers to carry out experimental science in the classroom, and relate it to real world experiences. Each written resource is accompanied by four videos; two with extra information on how to carry out the experiment and two on how the experiment relates to the real world. These create a flexible package for teachers, with something for everyone. In this experiment, students build instruments out of every day equipment, including elastic bands and pots, twanging rulers and beans in pots. They change the length and width of elastic bands and the length of the ruler to see what difference that makes to the sounds. The written resource was produced by the Ogden Trust. Real world video: Brian Cox visits a composer to find out how pitch and volume can affect our emotions. Research science video: Bruce, an acoustic researcher, has developed a device that can levitate small objects using sound.

Brian Cox school experiments: How can we clean dirty water?

(0)
The Brian Cox school experiments are designed to support primary teachers to carry out experimental science in the classroom, and relate it to real world experiences. Each written resource is accompanied by four videos; two with extra information on how to carry out the experiment and two on how the experiment relates to the real world. These create a flexible package for teachers, with something for everyone. Water is essential for life and the human body is around 60% water. We get most of our water from drinking it from taps or bottles and that water comes from reservoirs that are fed by rainfall, rivers and other sources. However there are many sources of water in nature that can be dangerous if we drink them, including the sea. Getting drinking water from these sources could prevent serious water shortages in some parts of the world. In this experiment, students are given a water mixture including stones, sand and salt and are asked to separate it to get pure water. They can sieve, filter and evaporate the water. Real world video: Brian Cox visits Mogden sewage plant to find out how sewage is cleaned before it returns to our rivers. Research science video: Danielle from King's College London explains how they use a form of separation called chromatography to ensure athlete's are not using banned substances.

Each written resource is accompanied by four videos; two with extra information on how to carry out the experiment and two on how the experiment relates to the real world. These create a flexible package for teachers, with something for everyone. In this experiment, students investigate the melting points of different types of chocolate by heating them in a water bath. Real world video: Brian Cox visits the Thorntons factory to learn about the different melting temperatures of chocolate. Research science video: Cathie Rae at University of Cambridge works with Rolls Royce to develop new materials with different melting temperatures for jet engines.

The Brian Cox school experiments are designed to support teachers to carry out experimental science in the classroom, and relate it to real world experiences. Each written resource is accompanied by four videos; two with extra information on how to carry out the experiment and two on how the experiment relates to the real world. These create a flexible package for teachers, with something for everyone. In this experiment, students use shapes made on black sugar paper stuck on lolly pop sticks to investigate how the shadow size changes as they change the distance between light source and screen. The written resource was produced by the Ogden Trust. Real world video: Anna, a radiographer in Cambridge, shows how X-ray shadows can be used to see inside animals. Research science video: Brian Cox visits India to see the total solar eclipse.

The Brian Cox school experiments are designed to support teachers to carry out experimental science in the classroom, and relate it to real world experiences. Each written resource is accompanied by four videos; two with extra information on how to carry out the experiment and two on how the experiment relates to the real world. These create a flexible package for teachers, with something for everyone. In this experiment, students try to germinate and grow plants from a seed using a variety of different materials instead of soil. The supporting The written resource comes from Science and Plants for Schools, and this and many other resources are freely available at www.saps.org.uk Real world video: Brian Cox visits an urban farm to find out how they grow salad with fish poo. Research science video: Jennifer at Rothamstead research studies the soil to find out what makes it healthy and better able to grow plants.

The Brian Cox school experiments are designed to support teachers to carry out experimental science in the classroom, and relate it to real world experiences. Each written resource is accompanied by four videos; two with extra information on how to carry out the experiment and two on how the experiment relates to the real world. These create a flexible package for teachers, with something for everyone. In this experiment, students take their heart rates before and after doing exercise and see what difference it makes. They look at the variation across the class before and after, as well as how long it takes their heart rate to return to normal. Real world video: Brian Cox visits the English Institute of Sport to find out why athletes look at their heart rate when they train. Research science video: Dr Dan Martin at UCL investigates how heart rate changes at high altitude to help patients in intensive care.
