The PhET (Physics Education Technology) simulation on density allows users to manipulate various parameters, such as mass, volume, and material, to observe the resulting changes in density. This ...

If you’ve ever wondered why the giraffe has such a long neck, the answer seems clear: it lets them reach succulent leaves atop tall acacia trees in Africa. Only giraffes have direct access to those ...

The authors do not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and have disclosed no relevant affiliations beyond their ...

Dark energy is responsible for the expansion of the Universe, but its true nature is still a subject of much debate. Computer simulations based on the latest astronomical data enable scientists to ...

The origin of our Universe remains one of the greatest enigmas of science, a question that seems to defy the limits of our physical understanding. For decades, cosmologists have struggled with the ...

Do your students ask you how to spell “because” three times a week, even though it’s on the word wall? It might be time to dust off those dictionary skills. And yes, I included the answer keys with ...

ABSTRACT: Hydrogeological modeling is an interesting and widely-used approach to improving our understanding of groundwater, both to test existing hypotheses on the behavior of hydrosystems and to ...

The PhET Interactive Simulationsproject at the University of Colorado offers over 100 interactive scientific simulations accessible in HTML5, meaning they can be used directly on any browser and ...

PhET is a fantastic digital alternative to the usual lab-based experimentation. This platform offers a selection of digital simulations to give a powerful experiment experience for students and ...

A neutrino moves through a gas of neutrons and is sensitive to correlations in spin and density in the neutron matter. These correlations determine how much energy transfers from the neutrino to the ...
