App Review: How Many Saturdays?

HOW MANY SATURDAYS? is an amazing data app from Exploratorium that helps young people explore units of time.

Users enter their birthdate and the app shows how much time they’ve lived in hours, minutes, and seconds. It also provides fascinating data based on the time an individual has been alive such as the number of Friday the 13ths, lightning strikes, presidential elections, and hours watching television. For each item, the app provides an image, animation, video, or audio to accompany the data.

Librarians will find this data app to be a fun way to gather information for autobiographical infographics. Ask youth to think about how they would display different types of data.

App Review: Universal Zoom

UNIVERSAL ZOOM: ALL ABOUT SIZES AND DISTANCES is a fascinating app published by Gamify It. From tiny, subatomic particles to stars and galaxies, this easy-to-use tool allows students to compare two objects to get a sense for the scale of the universe.

Designed for ages 9-11, students can choose from 150 objects presented in scale. The dynamic layout provides users with a sense for the relative size of common objects. Students will enjoy guessing and discovering how many times one object fits inside another. A limited audio element introduces each object encouraging users to read more about each object.

Measurements are available in both standard and meter systems making this an excellent tool for mathematics activities that involve using both units of length. This tool is also effective for a practical exploration of simple and scientific notation. The scale range is 1 yoctometer (1x10-24m) to 93 billion light years (8.8x10=26m)!

This engaging app encourages students to explore the idea of size and scale in a meaningful way. The high-quality images and rich content make this an app that is both appealing and useful for many STEM classroom applications.
