Tap your way round labelled science diagrams: the planets going round the Sun, the layers of the Earth, the water cycle, the atmosphere, the Moon's phases, the seasons and a volcano. Every planet has its own fact sheet. After exploring, answer 8 questions and put things in order. Useful for the Earth and space topic in primary science (Year 5 in England).
The Sun and the eight planets in order, with each one's size, distance, day, year, moons and temperature; the four layers of the Earth; the water cycle; the five layers of the atmosphere; the eight phases of the Moon; why we have seasons and day and night; and the parts of a volcano.
About 6 to 12. It matches what primary EVS and science books teach about space, the Earth, water and volcanoes.
No. Everything is drawn so it's easy to see and tap; the real Sun would be far bigger and the planets much farther apart. The fact sheets give the real numbers.
The Moon looks lit on opposite sides, and the seasons are opposite, in the two halves of the world. The diagrams show the northern half, and the questions say so.
Since 2006 scientists call Pluto a dwarf planet, so the solar system has eight planets.
