What Solar System Facts should know Kids.

In order to address the research issues presented above, the children’s ideas in the traditional content areas of astronomy investigated here were obtained using a 66-item multi-method survey instrument administered in the form of largely structured one-on-one interviews (Powney & Watts, 1987).

Twelve items, closely linked to the nature and content of the intervention and expected learning outcomes focused on the solar system.

The focus was on the main components of the solar system, its spatial arrangement and movements, and the age and origin of the solar system. A combination of verbal and non-verbal provocation techniques was considered the most reliable and non-threatening form.

The cognitive structure, ensuring a certain degree of methodological triangulation, and provide children with opportunities to respond according to their own explanations forces (driver and Erickson, 1983).

This included productive questions, production of annotated drawings, identification of objects in images and, to a lesser extent, word association. and concept mapping (White & Gunstone, 1992). All interviews, each of which lasted approximately 1 hour, were held outside the classroom, in an area of the Family School at children and according to the general guide to scientific interviews provided by Osborne and Freyberg (1985). Most of the responses and results of the tasks were recorded in writing and recorded in audio.


Some work was completed later. Children from both groups were interviewed. at least twice. The first and second interviews took place 3 months apart, immediately before and after the intervention. The children of the experimental group were interviewed for the third time. After an additional delay of 3 months. All investigative procedures were conducted in accordance with ethical guidelines for research with human participants.

According to qualitative analysis methods used elsewhere (e.g. Osborne et al, 1994; Vosniadou and Brewer, 1992, 1994; White, 1985), the interview protocols were coded in terms of responses identified at the level of individual items. This could be used to provide an indication of the correctness of the answer (See Appendix). Mental models were identified from response patterns within and between individual elements. Greater differentiation between
respondents was reached through scoring. This allowed a numerical and statistical analysis means of data analysis. The interview protocols were scored only once and at the level of individual articles. The score itself was derived from a procedure introduced by Harwood and Jackson (1993) and used a 4-point scale:  Paneles solares guatemala

Our solar system consists of eight planets orbiting our star, The Sun.

Our planetary system was formed 4.6 billion years ago!

For most of history, it was thought that everything in space moved around the Sun, however, around the seventeenth century, the idea that Earth is just one of the planets in the system began to gain popularity.

In fact, The Sun is just one of more than 200 billion stars moving in the Milky Way!

Our solar system consists of eight planets orbiting our star, The Sun.

The planet closest to The Sun is as wide as the Atlantic Ocean! 18 Mercuries would fit on Earth. The planet has no atmosphere, just like all other planets. There is also no water present on this dangerous planet! There, temperatures range between -180°C and 430°C / -290 ° F and 842°F.
