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?

The Greenhouse Effect
Read the Fine Print
Rating
0.0 stars

How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes. Then compare to the effect of glass panes. Zoom in and see how light interacts with molecules. Do all atmospheric gases contribute to the greenhouse effect?

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 ?
