Dancing worms experiment
Tools and Information
Honestly, I can’t emphasis enough how much Bumble Bee loved this activity. “What lives in dirt?” might seem like an obvious question to us, but Bumble Bee loved being able to verify her hypothesis (that worms live in dirt) for herself. She did sometimes ask for help with the digging part (perhaps our spade was a little big for her), but she really loved sorting methodically through the dirt to see if there were any worms in that particular load. When our sheet was too full of dirt, we emptied the ‘old’ dirt back into the same patch of garden and started digging again. Liquid worms science experiment Also people don’t think about the fact that they are they are vital in the food chain. So many different animals actually rely on earthworms as a source of food. So they are hugely, hugely important animals for all of us. And yet people don’t really give them a second thought! So start giving a bit more love to the humble earthworm!
Saving fred stem activity
In this activity, the sodium alginate immediately changes from a liquid to a solid when it contacts the calcium chloride solution. The calcium (Ca++) ions replace the sodium (Na+) ions and link the polymer chains together — much like the rungs of a ladder link the two sides. The result does not dissloves (is insoluble) in the calcium chloride solution. The squishy stuff inside the ''worms'' is unreacted sodium alginate. If you leave the worm in the solution longer, more calcium ions will react and the worm's ''skin'' will get thicker. How to Make Frankenworms Dance The only thing I foresee as being difficult with this experiment is keeping enough gummie worms for the experiment when I show it to my son. Oh well I guess I will just have to buy two bags of worms. It would just be mean to tell him no he cannot have any worms to nibble on in the name of science.
What’s the science behind the dancing gummy worms?
The version of the experiment is described using a small flask (250 mL). The large-scale version presented by Steve Spangler for television used a 5L flask. If you’re wishing to do the large version, just adjust the proportions as needed. Can You Save Fred? All earthworms, not just jumping worms, can harm forests by changing the soil structure and forest floor vegetation. Their feeding can result in a loss of soil moisture, compacted soil, exposed roots, erosion and an increase of pathogens and non-native plants. The result is less diversity of native plants and animals in delicate forest ecosystems.
