ExploreLearning Gizmos are interactive online simulations and case studies for math and science that power inquiry and understanding through hands-on learning and experimentation. With more than 550 Gizmos covering STEM topics for grades 3-12, students can dig deeper into subjects and really understand challenging concepts. As 2023 begins, we have two new science simulations joining our Gizmos library: Molecule Builder and Coriolis Effect, both for middle or high-school students.
In the Molecule Builder Gizmo, students can join atoms together to form molecules. There are two modes to the Gizmo: “Free build” and “Build from formula.” In the “Free build” mode, students can join any atoms together to make any structure, then enter the formula to check for understanding. If the molecule exists in the Gizmo’s database, students can then view a 3D model of that molecule. In “Build from formula” mode, students use an existing formula and structural diagram to create a challenge molecule. These molecules range from very simple ones like H2O to more complex, such as glucose (C6H12O6). Ring structures and isomers can also be explored. Molecule Builder is primarily for middle school students but can also be used in a high school chemistry class, especially when exploring the more complex molecules and isomers.
The Coriolis Effect Gizmo explores the physics behind the Coriolis effect. The Coriolis effect is the shifting of wind direction caused by Earth’s rotation, resulting in wind patterns that form hurricanes, trade winds, and other phenomena. The Gizmo simulates two kids playing catch, first on two trains, then on a merry-go-round, and finally on Earth’s surface. This demonstrates that the Coriolis effect is caused by a combination of the rotational motion of the thrower and catcher and the use of the rotating body (usually Earth) as a frame of reference.
Enjoy the new Gizmos, and have a very happy New Year!
