The Value of g on Other Planets Notes
Notes:
The Value of g on Other Planets Interactive is an adjustable-size file that displays nicely on tablets such as the iPad, on Chromebooks, and on laptops and desktops. The size of the Interactive can be re-sized to fit the device that it is displayed on. The compatibility with iPads, other tablets, and Chromebooks make it a perfect tool for use in a 1:1 classroom. This Interactive does not display very nicely on all phones and we do not recommend its use on many phones.
Teaching Ideas and Suggestions:
This Interactive is intended for use in a unit that discusses the concept of universal gravitation. Learners click on a photo of a planet and view the value of g on that planet. The mass and radius of the planet and one interesting fact about the planet are also stated. While the Interactive could be used as a teacher demonstration, it might be best used as an inquiry activity. Students could be given the following challenge ...
The value of g is 9.8 N/kg on Earth's surface but it is noticeably different on the surface of other planets. Using the Value of g on Other Planets Interactive, collect some data about the value of g on different planets. What seems to be the pattern in the data? Can you determine what variables affect the value of g on different planets? That is, what factors tend to make the value of g larger and what factors tend to make the value of g smallest? After conducting your investigation, write a claim that responds to these questions. Support your claim with evidence and reasoning.
