We want to place mark on the small cup so we can measure out mL of soil. Build a tower of sugar cubes in a shallow dish, then add a little colored water in the bottom.

How about if you tried a different sized container with different amounts of sugar and bleach. After dropping in the "PHOS" phosphorus test tablet, start the stopwatch. Measure 3 teaspoons of sugar and add it to your fourth container. Perhaps take a picture of you shaking a test tube or holding up a test tube and looking at it.

Water is one good example. You may have guessed that the results of this experiment will be different for different kinds of flowers. Use a spoon, spade, or knive to dig into the soil. Seed Dormancy Seed Dormancy is when a seed has fallen form the parent plant before they are able to germinate.

I estimate my sample to be between the M medium and H high levels of potassium. Notice the three phosphates using three phosphorus atoms. Using more soil will better represent the soil we are testing. Both sugar and bleach help flowers stay fresh. Keep pouring water from the cup with the soil until you collect at least 10 mL of liquid.

Using a ruler, create waves that move steadily against the sand. For the phosphorus test, we use 25 drops from our diluted soil extract. Now on to the potassium test. Try the same water experiments as 2 with water that has a little detergent in it. You probably want to take dirt that is a few inches down.

Now on to the potassium test. However, using four times more soil will also increase the concentration of nitrogen, phosphorus, and potassium four-fold.

Pour some distilled water into the mL beaker and then transfer enough distilled water to bring up the liquid level in the 50mL beaker up to the 40mL mark.

31 Water Experiments for Kids

For the color chart to be accurate, this amount of dilution was necessary. Roots that branch from the primary root are called secondary roots. Sponsored Links We had a lot of fun with these water experiments, and hope you do too.

In your kit is a glass jar with a stack of plastic cups inside. Cut" on a label, then stick it on your second flower container. Give one group of seedlings no water, another a moderate amount, and a third a lot. Seed Germination Germination dose not take place unless the seed is in a good environment the main keys for growing a plant are adequate water and oxygen and also sunlight.

Do some take longer to dry than others. This dilutes the soil-water extract four-fold. You probably want to take dirt that is a few inches down. Open one side of the folded filter paper. After five minutes you will check the color of the text tube water with the color chart.

We are doing this because we are using four times the soil that is normally used for these soil tests.

Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic. Also watch the stop watch. At five minutes you compare the color of the liquid to that of the chart.

Erosion Experiments for Elementary Kids

Use a medicine dropper to drop water onto a penny, one drop at a time. Examples of Hypotheses and Predictions Question Prediction How does the size of a dog affect how much food it eats. With the absorption of oxygen by the seed, energy is made available for growth.

What does the size of the holes have to do with how fast the water flows?. In a science fair setting, judges can be just as impressed by projects that start out with a faulty hypothesis; what matters more is whether you understood your science fair project, had a well-controlled experiment, and have ideas about what you would do next to improve your project if you had more time.

BE Soil Science Experiment 8 - Loss On Ignition Singapore Polytechnic DEWT/FT/1A/01 Aim: To determine the concentration of organic contaminants in soils by using the Loss in ignition method.

Peat Formation Peat is a partially decayed organic matter laid down in anaerobic, or lacking oxygen, conditions in forms when plant material, usually in marshy areas, is inhibited from decaying fully by acidic conditions.

It is composed mainly of peat moss or sphagnum, but also includes trees, grasses, and other marshland vegetation. It also includes many other types of organic.
