How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients. Do the same with chemical reactions. See how many products you can make with different amounts of reactants. Play a game to test your understanding of reactants, products and leftovers. Can you get a perfect score on each level?

Resonance
Read the Fine Print
Rating
0.0 stars

For advanced undergraduate students: Observe resonance in a collection of driven, damped harmonic oscillators. Vary the driving frequency and amplitude, the damping constant, and the mass and spring constant of each resonator. Notice the long-lived transients when damping is small, and observe the phase change for resonators above and below resonance.

Rating
0.0 stars

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 ?
