Science Experiments on Environmental Education and Biology
Now, imagine that a particularly active shrimp eats all the algae of its biosphere? What would happen? Probably, the oxygen would be subtracted by many processes, and since there is no more algae to produce more, the shrimp would die, suffocated. It is a question of simply putting water in an aquarium, collected from a natural pond and adding some animals and plants collected in the same environment like: water snails, little fresh water shellfishes, boatflies, whirligigs, larvae of dragonfly, nymphs of aquatic bugs, prawns, etc
Using sudsing soaps can cause your DW to leak or worse coat the washer parts with residue that will continue to sud in future wash cycles as well as leave residue on your dishes. Good price too.ReplyKim says: August 19, 2010 at 3:11 pmHow much Lemi-shine do you add?Replyeric says: June 24, 2011 at 8:54 am2 parts borax, 2 parts washing soda, 1 part food grade citric acid(more for hard water), the citric acid will eliminate or greatly reduce the white film
Since age is a factor in deciding whether or not to let them play with sparklers, why not spark their interest with something a bit more safe and just as fun- Glow in the Dark Bubbles that Bounce! You'll Need: * 1 cup water * 1 Tablespoon Dawn dish soap * 1 Teaspoon of glycerin * straw or bubble wand * 1 clean glove (or sock) - (this is to keep the bubble from popping) * 2 Tbs Water Based Glow in the Dark Paint First, let me start of by saying, if you know that you have Hard or Soft water you'll need to use Distilled water instead.

The Best Kids Science Experiments to Try at Home
Thanks for the awesome blog Reply Priya says January 6, 2015 at 6:06 am This is an awesome compilation of science experiments for kids! Thanks for sharing. Mostly simple baking soda and vinegar eruptions in a jar, but there have also been papier mache volcanoes, playdough volcanoes complete with ecosystems as in the link above, and sandbox volcanoes

I etched a little glass myself the other day and made a few mistakes here and there that taught a valuable lesson or two

The materials you will need are Dry Ice (solid carbon dioxide), a large bowl, a garbage bag, several smaller plastic bags, gloves, a hammer, water, sand, and a few drops of ammonia. Whenever science (especially chemistry) is depicted on film or television, you can almost guarantee that you'll see dry ice bubbling away in a colorful liquid

Dry Ice Experiments: Cool Science Projects with Dry Ice
Place a towel underneath it before putting it on any surface susceptible to damage.Dry Ice UsesDry ice can be used for special effects such as fog, science experiments, for cooling and freezing, and carbonation among other uses. If you try this with another type of container, such as drink bottles, the pressure can cause the bottle to explode causing damage to ears or the lid could fly off and hurt someone
Stop Slumping: What Makes Foams Stand Up Straight
Analyzing Your Data Charts For each data table, calculate the average distance from the starting level to the top of the liquid for each time increment. Experimental Procedure Note: Because the test tubes and rubber stoppers used in this experiment are not "food-grade" (designed for food preparation), and because raw eggs are not safe to eat, you should not eat any of the foams you make in your experiment
Some say it is strictly mechanical, where the surface of the mentos provides many cracks and jagged edges as nucleation sites for CO2 to form larger bubbles and escape. If you have a large class, it would be worthwhile assigning a different erupting volcano method to each group to spark a discussion on which worked best at the end of the lab
The reason for this decrease in volume can be attributed to the hydrogen bonds which develop between the alcohol molecules and the water molecules (See "Surface Tension of Water" to see a further explanation of hydrogen bonding).

Ingredients - Soap Bubble Wiki
While it is possible to make good bubble juice without pH adjustment, experiments have consistently shown that baking powder or baking soda + citric acid or simply citric acid benefit most bubble juice. The three key elements of most bubble solutions are the surfactant (usually provided by dishwashing liquid or some type of soap product), a polymer of some sort, and water

How to make your own giant bubbles - bubble recipe
..drr happyhooligans says September 14, 2014 at 9:53 am Great tips, Dustin! Thanks for sharing! Linda says June 11, 2014 at 3:35 pm can you substitute arrow root for the corn starch ? Reply happyhooligans says June 11, 2014 at 5:38 pm Hi Linda. Reply Carolyn says June 3, 2014 at 1:26 pm We make the most incredible bubble mix at my work with the same liquid ingredients and the a powdered bubble formula that we buy
Next time someone you know is baking, check the recipe to see if you can figure out what ingredients make the bubbles that make the cake or bread or cookies rise. If the recipe includes baking soda but no baking powder, it will probably also include an ingredient that's acidic-such as buttermilk, sour milk, or orange juice
The Ultimate Bubble Solution - ScienceBob.com
Because of the way that soap molecules are arranged, and the way they attract and repel from each other and the water, the soap creates bonds that give the water additional strength, and allow them them to last much longer. Bubbles will always be round when they are floating because the elastic nature of the soap bubbles allows air pressure to push equally on the entire surface of the bubble forming a sphere
Alternatively, it might be best to make your own liquid soap or start from a liquid soap base ( liquid soaps are made with potassium based lye ( potassium hydroxide) intead of sodium based lye). I know that that stuff will melt down but I wonder how that will affect the consistency? Also, where the heck does washing soda come from? Washing soda is sodium carbonate and according to wikipedia is produced by mining from alkaline salt flats in the USA, though it is also produced by the Solvay process outside of the USA (big geek heads up: I am familiar with the Solvay process because I used to work on the Onondaga Lake superfund site, where the Solvay process was heavily used and contributed to some of the area contamination.) The Solvay process also is used to produce baking soda, or sodium bicarbonate
To be fair, you should hold the bubble wand in front of a fan instead of trying to blow on it, that way you know that the amount of air being blown to make the bubble will be exactly the same
How To Build a Baking Soda Volcano Science Fair Project
The detergent helps trap the bubbles produced by the reaction so you get better lava.Add 2 tablespoons baking soda to the liquid.Slowly pour vinegar into the bottle. The resulting mixture should be smooth and firm (more water may be added if needed).Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape
What makes the food coloring in the milk move? How Does It Work? Milk is mostly water but it also contains vitamins, minerals, proteins, and tiny droplets of fat suspended in solution. All of these steps ensure that you have standardized the conditions as much as possible and have isolated a variable--the one thing that changes in the experiment
