The psychological nature of interest is studied in psychological and pedagogical disciplines studied atsome research works (M. F. Bieliayev, L. A.

The idea of integrating content and form of can be considered: for the "bachelor" level — "Modernteaching has always interested scientists and educators who innovative technologies of teaching physics in high school",worked practically. For instance, S. U. Honcharenko and I. for the level of "specialist" — "Using a training laser inM.

The following features of integration shouldLat. Am. J. Phys. Educ. Vol.7, No.2, June 2013 270 http://www.<strong>lajpe</strong>.<strong>org</strong>


e pointed out: 1) the integration is formed as theinteraction of isolated elements, that were previouslyscattered (new conditions that vary in quantity can arouseonly due to different elements); 2) the integration isconnected with qualitative and quantitative transformationsof related items, as a gradual change of separate elementstakes place. The elements are included into an increasingquantity of links, the accumulation of these changes leadsto changes in the structure, the appearance of new functionsof elements, i.e. the nascence of a new integrity; 3) theprocess of integration has its logical and profound basis (theconstruction of integration means, first of all, thedetermination of a common framework for combiningscattered elements of knowledge, the search and reasoningof the criteria of unity of different sets) [9].The objective of this article is to reveal the potential forintegration of knowledge in Nature Studies to formcognitive interest while teaching Physics at school, themain objectives include the possibility to integratetheknowledge in Nature Studies to create and enhancecognitive interest of students by studying the theme"Nucleus. Nuclear energy "(Grade 9).Integration of knowledge of nature studies as a means of forming cognitive interests…- the lesson should deepen and expand the students'outlook;- the lesson should encourage the development of skillswhile studying popular scientific literature, stimulate thestudents' desire to acquire new knowledge independently.It is hard to imagine the modern approach to teachingPhysics without making interdisciplinary connections withother subjects connected with natural sciences. Usinginterdisciplinary connections intensifies the educationalprocess, stimulates students' learning interest, promotes theoutlook expanding. In particular, the links between physics,biology and chemistry that are successfully revealed andshown, reinforce the practical orientation of both a schoolsubject and the educational process in general. Thus,integration aims at laying the foundation for students'holistic understanding of nature and society and formingtheir personal attitude towards the laws of theirdevelopment [11, p. 26].Here are specific examples of the integration of naturalknowledge to create and enhance students' cognitiveinterestfor Physics while studying the theme "Nucleus. Nuclearenergy "(Grade 9).III. IMPLEMENTATION OF INTEGRATIONOF THE KNOWLEDGE OF NATURE STUDIESAS A MEANS OF FORMING COGNITIVEINTEREST WHILE TEACHING PHYSICS INSECONDARY SCHOOLThe term "integration" is derived from Latin integratio —recovery, replenishment, from integer — whole, whichmeans the process and result of interaction betweenelements (with properties given), that are accompanied bythe restoration, establishment, complication andstrengthening of significant ties between them on the basisof sufficient cause, resulting in emerging integrated object(system) with qualitatively new properties, which are storedin the structure properties of individual source elements[10, p. 337]. Methodical basis of an integrated approach tolearning is development of the knowledge about thesurrounding world, establishment of interdisciplinary andintersubject connections while teaching Physics. Thus, weconsider it advisable to call any lesson having its ownstructure an integrated one, if the knowledge, skills andresults of the material analysis that is studied by methods ofother Nature Studies disciplines are applied for itsconduction. Because of it integrated lessons are also calledinterdisciplinary. Such basic didactic requirements towardsan integrated lesson can be pointed out:- the lesson should have a specific educational andcognitive aims that are distinctly formulated;- the lesson should arouse pupils' interest for establishinglinks between adjacent fields of science;- a high activity of students to apply knowledge fromother disciplines (fields of sciences should be provided inthe classroom);Table I.

Stepan Velychko, Victoria Buzko and Viktor Matsyukradioactive radiation influences the heredity intensively andaffects the genes in the chromosomes in particular. In mostcases, the effect is adverse.The exposure of living <strong>org</strong>anisms can have some benefitas well. For example, the cells that multiply rapidly inmalignant tumors are more sensitive to radiation thannormal ones. The inhibition of cancer by γ-rays ofradioactive drugs that are more effective for this purposethan X-rays is based on it.Students consider it to be interesting that scientiststhemselves have only recently realized that radon is themost significant of all the natural sources of radiation. It isan invisible, tasteless and odorless heavy gas, which is 7.5times heavier than the air. According to the United Nationsestimates radon and its products of radioactive decaygenerate approximately 3/4 doses of radiation received bythe population from terrestrial sources of radiation. Aperson receives the bulk of the radiation dose from radonwhile being in the rooms that are not ventilated. Then it isadvisable to analyze the diagram concerning the influenceof a room ventilation on the contents of radon in it (Fig. 1).FIGURE 1. The influence of airing the room on the contents ofradon in the air of a bedsitter in a single-family house.It is useful to show the diagram at the Physics lesson, whichis conducted as a conference. It should be noted that thepupils were previously offered to do an individual or groupresearch or mini-projects. The results of pupils' independentresearch can be integrally presented as diagrams, that areillustrated in Figure 2 and 3.μSi/h0,180,160,140,120,180,160,170,14 0,150,14 0,14 0,140,12 0,130,13 0,130,120,10,080,060,040,0201 2 3 4 5 6 7 8 9 10 11 12 13 objectsFIGURE 2.

Such a research develops pupils'cognitive interest for Physics and forms independencewhile carrying research work out. Besides theoreticalinformation, we consider it appropriate to reveal theessence of the concept of background radiation, naturalradioactivity, measured in Bq/kg, radiation of substancesthat enter the human body through food. However, it isappropriate to reveal the possible effects of radioactivity,which influence the human body, getting there by food andrespiratory tracts. Therefore, the ability to explore food'sradioactivity is an important aspect of life.The equipment and materials used in this homelaboratory assignment consist of a dosimeter, buckwheat,instant coffee, milk and other products.Procedure:1. Set the dosimeter on the mode of estimation of volumeactivity of radio nuclides in the samples.2. To measure background activity, then the total activitywith the product under study and to calculate the activity ofthe product.3. To write the results into the table (Table II).4. To draw conclusions.Special attention should be paid, in our opinion, tosolving integrated and interdisciplinary problems. Suchtraining problems in physics with interdisciplinary contentare a source, means and a necessary condition for pupils'interest. If a student has solid knowledge and skills in thefield of Physics, this ability to solve applied problemssignificantly activates his cognitive activity. It is possibledue to the use of interdisciplinary interaction [13, p. 267].Lat. Am. J. Phys. Educ. Vol.7, No.2, June 2013 272 http://www.<strong>lajpe</strong>.<strong>org</strong>

Thefollowing sums can serve as the examples of such tasks:1. To give examples that characterize the quantity andsizes of atoms and molecules:22a) There are 2⋅10drops of water in the Black Sea.
