On the right side, press the button for the desired experiment
Move the eyedropper from the reagent at the bottom and take it to the test tube.

In the case of the burette reaction, both the sodium hydroxide solution and the copper sulfate solution must be added before the reaction occurs.
Likewise, in the case of Benedictine reactions, Benedict solution should be added and heated with an alcohol lamp.

You can detect nutrients in starch, protein, fat and glucose.

You can also detect nutrients in milk. For reference, it does not contain starch ingredients in milk.

Finally, the unknown substance at the bottom changes randomly when the button is pressed.
So it would be nice to let students find out what nutrients they have.

In making

I was able to experiment with starch and saliva.
(If the starch is mixed with saliva, it breaks down into the sugar, so it does not react to the iodine reaction and only responds to the Benedictine reaction - it's actually broken down into the sugar, so it's not clear whether it comes out as it is in the virtual experiment)

I have also been able to experiment with semipermeable membranes.
I compared starch in semipermeable membrane and glucose in semipermeable membrane, Iodine reaction and Benedict reaction,
You can see what a substance is.

It is better to show the same program continuously and repeatedly every hour.
Anyway, from day to day, the program becomes familiar, and I seem to get used to it.
