Did you ever imagine that you can use light to move a microscopic plastic bead? Explore the forces on the bead or slow time to see the interaction with the laser's electric field. Use the optical tweezers to manipulate a single strand of DNA and explore the physics of tiny molecular motors. Can you get the DNA completely straight or stop the molecular motor?

Une série de simulations provenant de l’Université de Colorado à Boulder pour les 9e – 12e au sujet des sciences. Cette simulation démontre le processus de solutions acido-basiques.

Comment les acides forts et faibles diffèrent-ils ? Utilisez des outils de laboratoire sur votre ordinateur pour le découvrir ! Plongez le papier ou la sonde dans la solution pour mesurer le pH, ou insérez les électrodes pour mesurer la conductivité. Ensuite, observez comment la concentration et la force influent sur le pH. Une solution d'acide faible peut-elle avoir le même pH qu'une solution d'acide fort ?
