is anything in your terrarium from brazil?
anyway... I'm just as annoyed at times that these science programs seem to want us to buy house plants in January. Apologia Elementary is like that and so is jr. high. I'm just growling... grr... giggle giggle...
hmm.... would there be any options at a pet supply store with real plants?
another way to get the same idea if you have no house plants of any kind in your house, or local places... The point of the experiment is about acid rain. How about this?
You could soak an egg in vinegar and another egg in regular water. check the effect. watch the bubbles forming on the vinegar soaked egg, ooh.. there's a funky reaction going down right?
check it in a few days.
now... I realize that an egg isn't a plant and that might not connect with all children that the acid rain can have some effects on plants. but it's really cool to do that with the egg, and it shows up again in chemistry and physics experiments.....
So, you could come back to this experiment in a few weeks. Soak some beans/seeds overnight. Start them growing and see the effects. I have no idea how it will turn out, but it sounds neat.
if all else fails.... (come back to it in the spring to do at home and just read about it and read others results)
I was hoping on this link the student would have had pictures
he used lemon juice and distilled water. so you might want to use some distilled water.
ah ha! pictures...... if you have to wait a few weeks/month to get real plants and try this at home... you could just look at pictures from this person's experiment

looks like they used ivy.... do you have any ivy outside in the yard that you could bring inside....
(anyway... that's my thought process on it when something seems hard to find.
Are there pictures out there to at least show my kiddo and then do the thing later?
Is there a way to feel similar, but not exact effects with things I do have?
