Terraqua Column: How does water affect land and animals?

How does salt affect plant growth, like when we use salt to de-ice snowy winter roads? How does adding fertilizer to the soil help or hurt the plants? What type of soil best purifies the water? All these questions and more can be answered by building a terrarium-aquarium system to discover how these systems are connected together.

    So the water can travel (“wick”) between the two places. If you really want to be a scientist about it, you can try all sorts of materials (nylon, yarn, twine, etc) and see which works best.

    why cotton string?

  3. Aurora says:

    Nearly all do! There’s a couple that I still haven’t made videos for yet.

  4. Yunhee Christian says:

    Do all of your videos have an experiment with them?

  5. Melody Konkel says:

    thanks aurora

    For piping water up through the column. (I assume the “4” was meant to replace the word “for” and did not indicate the length of the string?)

    WHAT IS THE STRING 4

  8. Melody Konkel says:

    thanks

  9. Michelle Stevens says:

    Thanks!

    Yes, but you’ll have to monitor it closely to make sure the plants are thriving. It’s such a small ecosystem that it’s going to be hard to keep the humidity and soil conditions just right. Refer to the info on carnivorous plants to see what you need to make them thrive.

  11. Michelle Stevens says:

    Could I put a carnivorous plant in the TAC?

  12. says:

    thanks

  13. Aurora says:

    Use less water? Punch a few holes to drain it out? Leave it in the sun for a few hours with the top off?

  14. says:

    mine is way to watery. how do i fix that

  15. Aurora says:

    Yes – it grows whatever you put in.

  16. says:

    can it still grow weeds

  17. Patricia Ujdur says:

    there are lots of varieties of snakes!

  18. Aurora says:

    Do fish make…? Air bubbles? Spit? 🙂

  19. Chani Krongold says:

    This is Batsheva,
    Do fish make?

  20. Aurora says:

    Sure – goldfish are hardy, but chose a small one or it will pollute the water more quickly than it can sustain itself.

    CAN U PUT A FISH IN THE TAC ?
