Whether in the classroom, outdoors or on project days: in this robust aluminium case, you will always find the right device for carrying out fascinating experiments with schoolgroups.

Up to 4 work groups can work on and investigate interesting topics in parallel.

All data are saved on SD memory cards.

Evaluation of the data can be carried out e.g. at home, as homework.

The measure evaluation software is included for FREE and may,of course, be used privately by each pupil.

TIP:

Principle A visit to a water treatment plant reveals some fascinating procedures and purification methods. We will not merely be concerned with interesting impressions, but instead we will increase our understanding for microbiological processes by measuring the key parameters: temperature, pH and salinity.

This device is also ideal for use e.g.in the context of a school hiking day: here, a topografic profile can easily be produced with the weather sensor. In Geography lessons, the data can be evaluated and interpreted together. If the height is then set against the temperature, humidity relative to the path, or temperature relative to the time of day, great discoveries can be made, which are both practical and fun.

The methods are mainly chemico-physical determinations acc. to BACH. They allow an objective assessment of the water quality, and are referred to by the Scottish and American Environmental Authorities, as well as those of some German Federal States, in their reports on water quality. The chemico-physical examination methods always give momentary values, and so allow measurements of variation overtime (daily and seasonal variations) as well as at different positions (e.g.pollution by influents). Added meaningis given by supplementing these methods with biological methods, which aim at the documentation of long-term changes in the condition of the body of water.

Comparison of the heat capacities of water and soil

Principle Various types of woodland exhibit different sorts of climate data.

Temperature, humidity and lighting conditions do not only depend on meteorological factors but also on the nature of the vegetation.

The density of the tree canopy determines how much light can penetrate and therefore affects the temperature. The low density of vegetation on a managed highland forestry estate (often beech forests at European latitudes) also affects the movement of winds in the forest, which also affects humidity. In this outdoor experiment, we will be conducting measurements on various types of woodland during the same day and at approximately the same time in order to eliminate meteorological differences as far as possible.

Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanicor similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlled by these enzymes may be disturbed or prevented. Using urea hydrolysis with the aid of urease, the blocking of the enzymes by heavy-metal ions can be measured with common laboratory methods.

Salinity of soils and plant substrates Principle Demonstration experiment using wireless data communication to send readings to a large-size display. Knowledge of soil characteristics is highly important for agriculture. To familiarise students with this topic, two sub-experiments use pH readings to demonstrate how different soils from different places can be (sub-experiment "Characteristic pH values for soils") and how varied the soil can be down below the surface (sub-experiment "Soil profiles").

Raised bog and fen

Principle Demonstration experiment using wireless data communication to send readings to a large-size display. How suitable are certain soils and plant substrates in terms of plant nutrition? This experiment is concerned with the measurement of conductivity, which gives an indication of which of the studied soils and plant substrates already contain nutrient salts necessary for the growth of plants and which ones would be better if nutrients were added in the form of fertiliser. Plants gain their nutrition in the form of salt ions from the soil. The most important of the 16 nutrients which plants need to grow are nitrogen in the form of nitrates and ammonia, phosphorus in the form of phosphates and potassium in the form of potassium salts. In addition, soils need to have lime (calcium carbonate) to reduce their acidity (reduction in pH). For agricultural purposes, such nutrients are added to the soil in the form of inorganic fertilisers. For house plants, fertiliser-enriched potting soil is used.

Digestion in the stomach

The digestion of proteins begins in the stomach. The gastric juices contain the enzyme pepsin along with diluted hydrochloric acid, which activates the enzyme from its precursor, pepsinogen. In the experiment, boiled fish is added to test tubes with water, enzyme solution, hydrochloric acid plus a mixture of enzyme solution and hydrochloric acid. In order to simulate the body temperature, the test tubes are placed in a large glass beaker which serves as a simple water bath. After a few hours, it is clearly evident that proteins break down only in the preparation with both pepsin and hydrochloric acid.

Impact of the forest type on humidity, temperature and brightness Principle Various types of woodland exhibit different sorts of climate data.

Temperature, humidity and lighting conditions do not only depend on meteorological factors but also on the nature of the vegetation.

The density of the tree canopy determines how much light can penetrate and therefore affects the temperature. The low density of vegetation on a managed highland forestry estate (often beech forests at European latitudes) also affects the movement of winds in the forest, which also affects humidity. In this outdoor experiment, we will be conducting measurements on various types of woodland during the same day and at approximately the same time in order to eliminate meteorological differences as far as possible.

Salinity of soils and plant substrates

The Cobra4 Sensor-Unit Conductivity, with stainless steel electrodes

How suitable are certain soils and plant substrates for the nutrition of plants? This experiment is about measuring the conductivity, which in turn provides information as to which of the examined soils and plant substrates already contain nutrient salts for plant growth and to which of them nutrients should be added in the form of fertilisers. Plants obtain their nutrients in the form of ions from the salts in the soil. The most important nutrients of a total of 16 nutrients that a plant needs forits growth are nitrogen in the form of nitrates and ammonium, phosphor in the form of phosphates, and potassium in the form of potassium salts. In addition, the soils also require lime (calcium carbonate) in order to avoid acidification (decrease of the pH). For agricultural production, these nutrients are added to the soil via inorganic fertilisers, while potting compost with fertilisers is used for house plants.

Bacteria and mining - microbial extraction of ore

by Thiobacillus ferrooxidians and thiooxidans

Microbial synthesis of ethanol by Zymomonas mobilis subsp. mobilis

Principle Principle Scientists first recognised importance of certain bacteria for the extraction of metals from ore in the 1950s. Nowadays the microbial ore leaching with so-called 'lean ores' represents more than 10% of the total production of copper in the USA alone. The bioreactor shown here can be used to clearly demonstrate to the students this method of extraction (e.g. copper from copper ore) using such bacteria (Thiobacillus ferrooxidans).

Literature for this experiment as follows: Demo advanced Chemie Handbuch Komplettversuche (CET) 01855-01 German Complete Experiments Chemistry/Biotechnology 01855-02 English P1313900

The properties of the micro-organism Zymomonas mobilis have been used in the production of alcohol for centuries. Nevertheless, the bacterium in palm wine and pulque, the fermented juice of the agave plant, was not identified and recognised as being responsible for their alcoholic fermentation until the twentieth century. Zymomonas was found to synthesize ethanol much more effectively than yeast does. In this experiment, Zymomonas mobilis is grown in a bioreactor. The medium is blended by means of a magnetic stirrer and its temperature is controlled by means of a heating coil and a water bath with thermostats. The discharge of used medium and the supply of fresh medium can be dispensed with. This is a so-called 'static culture' (batch culture). The cell density can first be determined photometrically in the samples taken and the cell count can be determined in the counting chamber, and those data can be used to generate a growth curve.

Chemical and enzymatic tests show the consumption of glucose and the production of ethanol. The experiment is easy to perform.

It does not take long to prepare. The evaluation of the test results is very conclusive and clearly illustrates the methods of biotechnology.

Simulates a generalised nerve cell with an apical dendrite and its synaptic contacts, a cell body (soma) and a nerve fibre (axon) with myelin sheathes and a Ranvier's ring.

The dendrite comprises exciting, inhibiting, presynaptic and Hebbian synapses which are marked by the corresponding colours of the sockets.

Here the axons end in presynaptic buttons.

These are represented together with a part of the (afferent) fibre providing the signal.

The connection between the (efferent) axon of a neuron unit which leads away or the stimulus output socket of the operating unit and a synapse is established by means of a white cable which is inserted into the desired synapse socket.

The yellow sockets serve for the derivation of the state of excitement of the simulated neuron.

They are connected to a computer interface.

The action potentials can be made audible with the aid of the integrated acoustic monitor.

The turning knob "S" serves for setting the "firing threshold" of the neuron.
