Soil experiments for kids: Theme “earth / ground” – experiments in preparation

Soil Experiments For Kids 1: Water Capacity

Material:

  • Filter paper or cotton
  • stopwatch
  • each 3 pots
  • beakers and graduated cylinders
  • each 500 g sandy soil
  • clay soil and potting soil

Implementation:
The holes in the flower pots are sealed with filter paper or cotton. Fill the pots close to each under the rim with the soil samples.
On each sample is poured slowly a lot of water of 300 ml. The leaked water is collected in beakers and 3 – 4 times emptied through the samples.

Responsibilities:

Miss the time to expire before the first drop of water below.
Determine with the help of the measuring cylinder, the volume of leaked water.
Think about where the captured water connected.

Soil Experiments For Kids 2: lime in the soil

Material:

  • Porcelain dish
  • dropper bottle with 10% hydrochloric acid
  • soil samples of sandy soil
  • clay soil and potting soil

Implementation:
Fill some sand in a porcelain dish. Give then a few drops of hydrochloric acid added.
Repeat the experiment with the two other soil samples.

Responsibilities:
How much calcium is in the ground?

Information:
Based on the duration and intensity of effervescence can you determine the calcium content:

  • effervescence no lime
  • closer to the ear, it hisses less than 1% lime
  • weak effervescence 1-2% lime
  • clear effervescence 2-4% lime
  • strong, long effervescence than 5% lime

Soil Experiments For Kids 3: separation of soil at different grain sizes (gravel, sand, clay)

Material:

  • Air-dried soil samples
  • several mortars and mortars
  • three-part screen

Implementation:
The air-dried soil samples were crushed with a mortar. The samples in the three-piece victory by vigorous shaking on the grain sizes are separated.

Responsibilities:
Determine the composition of the soil according to particle size using the screen.

Soil Experiments For Kids 4: Determine soil types

Material:

  • Various soil samples
  • water

Implementation:
Experiments, the sample between the palms to roll out quickly to a pencil-thick sausage.

Responsibilities:

Determine if the soils are not roll out or roll out.
not roll out: Sande
roll out: loams and clays
Check the cohesiveness of the sample between the thumb and index finger
non-cohesive: Sand
cohesive: strong loamy sand
Squeeze the sample between the thumb and index finger close to the ear.
strong crunch: sandy loam
no or faint crunch: loams or clays

Soil Experiments For Kids 5: How are the various components in water?

Material:

  • Soil samples (sand, loam and compost) in each 200 grams per sample
  • a glass jar (750 ml) with screw cap
  • water
  • adhesive labels
  • tape measure

Implementation:

Cleaning up the samples from all parts of such coarse roots, stones etc..
Coarser crush boulders and fill entire earth into the glass.
The glass three-quarters fill with water.
Screw the glass and the contents vigorously shaken.
The label with the information (sample type, date and time) label and stick on the glass.
Responsibilities:

Observations after 30 and after 60 minutes of record.
Observations also record the next day at school, make sketch.
Thickness of each layer deposition, and compare well with other “elutriated” samples.
Screw the glass and the contents vigorously shaken.
Explanation of Bebachtungen.
Explanation:
With the help of the individual Schlämmprobe Bodenbustandteile / material components are separated. According to their grain size are deposited from the heaviest stones first, followed by sand grains. It is rather light soil fractions (silt) from. The humic components form the uppermost layer. The finest particles (clay) with a diameter of 0.002 mm are deposited so slowly that they deteriorate the water for a long time. Forest soil has the highest proportion of humus components, however, is free from bare floor humus. Coarse organic material such as plant parts or the remains of animal carcasses floating on the surface.

Soil Experiments For Kids 6: pH indicator paper with the determination of a Bodenfiltrats

The pH of the sample gives information about whether there is a soil with acidic or basic properties. Some plants are found only on acidic soils, again only on some basic ones.Time required approximately 10 minutes.

Material:

  • Small fraction of the soil sample
  • distilled water
  • filter paper
  • small beaker
  • pH test strips

Implementation:

Give about one tablespoon of your soil sample into a beaker. The beaker should be filled with soil material to a third.
Give now distilled water into the beaker until it is nearly full and stirring the mixture thoroughly.
Fold a circular filter paper into a funnel shape and puts it into the beaker. Will seek to ensure that no water from the top of the filter is running, otherwise the sample unusable.
Waiting for enough clear ground solution is infiltrated into the filter.
Take a pH test strips and keep the test area shortly into the clear floor solution.
Let dry for the field test, comparing the staining with the values ​​specified on the package.
Measuring your quoted value, compares the result with the accompanying table (soil pH) and pick up one more information about the importance of soil pH.
