**The usage of IT at English lessons**Our group: Sorokina Dasha, Gushchina Lena, Chuikova Anna Bondar Evgeniy, Gabdrahmanov Evgeniy English teacher: Snegireva Natalia Vladimirovna**Contents**PHYSICS GEOMETRY**PHYSICS**SCIENTISTS MAIN TERMS IT WAS INTERESTING TO KNOW BACK**SCIENTISTS**LORD KELVIN ALBERT EINSTINE BACK**MAIN TERMS**Motion Waves Energy BACK**IT WAS INTERESTING TO KNOW**BIG BANG LASERS RADIATION BACK**GEOMETRY**SCIENTISTS MAIN TERM IT WAS INTERESTING TO KNOW BACK**SCIENTISTS**EUCLID Archimedes BACK**MAIN TERM**SOLID FIGURES BACK**IT WAS INTERESTING TO KNOW**Graphs Statistics Trigonometry BACK**GRAPHS**• We can see the relationship between two or more pieces of information by using graphs and can present numerical data as a picture. This allows more simply to understand and use the data. BACK NEXT**GRAPHS**The simple graphs: • Vertical axis (Y-axis) • Horizontal axis (X-axis). The point where the axis meet is known as zero point. BACK**Statistics**• Statistics is the branch of mathematics concerned with collecting and interpreting data. The data are often collected by interviewing a sample group of people. BACK NEXT**Solidfigures**• The solid figures most easily categorized are called polyheadra. • Five regular polyheadras: • Tetrahedron (four triangular faces) • Octahedron (eight triangular faces) • Dodecahedron (12 five-sided faces) • Rosaheadron (12 triangular faces) • The cube (six square faces) BACK**Euclid**• Worked in Alexandria, Egypt, 2300 years ago; • He is a famous for writing Elements, a series of 13 books; • Wrote on music and other subjects. BACK**Statistics**• The information going from the sample group of people can be useful in government agencies and businesses. BACK**Trigonometry**• Trigonometry is the branch of mathematics connected with the relationship between sides and angles of triangles. • Trigonometry can be used to find the measurements of unknown sides and angels of triangles. BACK**Motion**Everything in the world is in motion. Examples of motion: • Objects (rocks and buildings) • Flight of an airplane and etc. BACK NEXT**MOTION**The Earth itself is moving around the sun. All motion requires force to start, to change speed or direction, or stop. BACK**WAVES**Some waves transport energy through matter by causing the matter to vibrate. Types of waves: • Transverse (crosswise) waves • Longitudinal (lengthwise) waves BACK**ENERGY**Everything happens because of energy. Types of energy: • Chemical energy • Light energy • Nuclear energy BACK NEXT**ENERGY**Energy can switch one form to another when work is done. BACK**Albert Einstein**• Introduced new theories about the nature of time, space, energy, and gravity. • His theories were used to produce nuclear bombs. BACK**Lasers**• «Light Amplification by stimulated Emission of Radiation» • A devise for converting ordinary light into an intense narrow bean. • Passes an electric current through material: solid, liquid, gas. BACK**Radiation**Alpha rays Beta rays Gamma rays 2 protons 2 neutrons + charge No mass No charge Electrons - charge BACK**Lord Kelvin**The founder of modern British physics. His name is given to a unit of temperature. Calculated that the lowest t any matter could achieve -273C. BACK**The Big Bang.**• Some scientists believe that the universe was born 15billion years ago in a colossal explosion called the Big Bang. • The young universe began to expand rapidly and tiny particles of matter formed. • Over millions of years this matters began to develop into the first galaxies. BACK**Archimedes**• discovered the value of “pi”, which is the ratio of the circumference of a circle to its diameter; • looked for ways of measuring the volume and mass of irregular objects; • discovered the principle of displacement.
