Space Science Tutorial: Spring and Neap Tides

This space science tutorial video explains why the oceans experience two extra large tides, called spring tides, and two smaller tides, called neap tides, each month. This combination of the moon and sun's gravities, only align at the New Moon and Full Moon, and exaggerate the tides at these times, resulting in Spring Tides. On the other hand, the sun's and moon's gravities don't align at the First and Third Quarter, so the tides at these times are smaller than usual, resulting in Neap Tides.

We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program. Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class! The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival. It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences. Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth. About Ian Stuart (Email: ian.douglas.stuart@gmail.com): The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world. Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths. Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne.

The earth also moves towards the moon, but not so much as it's further away. Finally, the far-side ocean moves towards the moon least, because it's farthest from the moon. These movements due to gravity create 2 high tides and 2 low tides as the earth rotates through 24 hours. But there's a big object that's missing from our diagram- the sun. If we back up, we can also see the sun and how it lights up both the earth and moon into their day and night sides. In this New Moon position we can only see the moon's night side, so it's invisible to us from earth. It's right in front of the sun. As the moon completes its monthly orbit, our view on earth changes to the 1st quarter where we can see half its day and half its night sides, then to the Full Moon when we can see its whole day side, then to the 3rd quarter, before returning to the New Moon to start all over again. Does the sun also pull on the oceans and make them bulge like the moon does?] Yes, but the sun is much further away than the moon making its tidal effect is only about half compared to the moon's.
