Gummy candies aren't much more than a whole lot of gelatin and some flavoring. Yes, that simple. You might have all the ingredients you need in the house right now. As for equipment, the only thing you might not have is a mold. Ah, the mold. This is where you can go a little crazy. You can use actual candy molds from candy supply houses, silicone ice cube trays (like we mentioned above) or simply improvise. I like to keep the final product on the small size because I like the idea of having a handful of them.
If you can't locate a mold, just pour the mixture out onto a baking sheet, and cut it with a pizza cutter when it has set. And if you want to get super creative, read up on making your own custom molds with food-grade silicone. The following basic recipe makes a relatively few number of candies — about one ice cube tray — but you can easily scale it up to make dozens more of these gummy goodies. Learning how to make gummy candy turns out to be so quick that you can even make successive batches in different flavors.
And once you have the recipe and technique down, you can experiment with adding additional flavors to the gummies. A good example is adding ascorbic acid powder for tart-flavored gummies (add the ascorbic acid after melting the mixture). 1. Into a heatproof glass measuring cup, pour the cold water. Sprinkle the gelatin over the water while stirring with a rubber spatula. The resulting mixture will be a super-thick mass, much like clay, but keep stirring.
When all the gelatin is sprinkled on, try to get all the dry bits off the side of the measuring cup and off the spatula (as well as any moist bits), and press onto the surface of the gelatin mass. 2. Cover the measuring cup with plastic wrap, and let the mixture rest for 10 minutes.
Fill a medium-size saucepan half full with water, set over medium heat, and bring the water to a simmer. Remove the plastic wrap from the measuring cup, and place it in the water. Let the mass of gelatin melt, stirring occasionally and gently. When the mixture is clear, turn off the heat, and let it sit for 1-2 minutes. 3. Very carefully pour the hot mixture from the measuring cup into the molds. If the syrup gets too thick, you can reheat it a little. If the candies contract a fair bit as they cool, top them off with a second round of the gelatin mixture. Place the mold in the freezer for 10 minutes, then in the refrigerator for another 5-10 minutes. Peel them out of the molds and serve.
A population is a group of the same species that lives in an area at the same time. For example, all the moose on Isle Royale make up a population, as do all the spruce trees. Ecologists determine and analyze the number and growth of populations and the relationships between each species and the environmental conditions. Factors that control populations. The size of any population depends upon the interaction of two basic forces.
One is the rate at which the population would grow under ideal conditions. The second is the combined effect of all the less-than-ideal environmental factors that limit growth. Such limiting factors may include low food supply, predators, competition with organisms of the same or different species, climate, and disease. The largest size of a particular population that can be supported by a particular environment has been called the environment's carrying capacity for that species.
Real populations normally are much smaller than their environment's carrying capacity for them because of the effects of adverse weather, a poor breeding season, hunting by predators, or other factors. Factors that change populations. Population levels of a species can change considerably over time. Sometimes these changes result from natural events. For example, a change in rainfall may cause some populations to increase and others to decrease. Or the introduction of a new disease can severely decrease the population of a plant or animal species.
