1 Organizing moment We will conduct lesson as a trip " Trip in a fairy-tale" you like to travel... 2. Strategy a reiteration is a limbering-up " the Physical alphabet" 1. to show in letters denotation of mass 2. to show in letters denotation of closeness 3. to show in letters denotation of volume 4. unit of mass 5.unit of closeness 6. unit of volume Your knowledge opened a gate in a fairy-tale. And fairy-tale such " In some reign the state inertia of tendons Ivan Царевич and he had three sisters " Mass", "Closeness", " Inertia". He gave them marry. Time passed. Ivan Царевич after missed.

On a way on a bridge a stone, stopped the way . On камене questions of physical tasks . 4. Decision of tasks 1. To calculate the volume of stone, if mass of 1000кг, is a closeness 1250 kg/of м3? 2. To calculate the closeness of water in the river, if width a 250 cm, length 1000см, depth 5м? 3. At braking of coach, what physical phenomena are observed? Farther Ivan Царевич went with the warriors. On a road met Baba Ягу that told about magic locks with a secret and decided to help Ivan to the czarevitch, but only in case that warriors will execute next tasks. 5. Laboratory experiment devices on school desks (scales, are a set of loads, body of different form, measuring cylinder) 1. To define the closeness of walls of log cabin of Baba of Яги 2. To define the closeness of tableware of Baba of Яги. 3. To define the closeness of potato, favourite dish of Baba of Яги Strategy " of Органайзер- table" to fill a table № | substance | m(kg) | ρ (kg/m3) | V (m3) | 1 | Tree | | | | 2 | Aluminium | | | | 3 | potato | | | | Farther moved in a way. And front patrimony of Scrag Immortal. What to open gate, on that a lock hangs with a secret, it is necessary to execute a task. 6. Strategy органайзер is a cross-word " Inertia" Here and a gate was opened. Saved Elena wonderful. Played wedding. Let mentally we will cast a glance the way of Ivan Царевича we will think, as we overcame obstacles.Knowledge of physical concepts, of units of measuring, physical phenomena. 7. Reflection: fixing of basic formulas and concepts, units : Work for органайзер of -таблица ( table of closeness of solid ) For the sisters of crown gold, silver, copper lonely volume. 1. What crown does have large mass? 2. What - most less? 3. What crown does have a high-slay? 4. What less closeness? 6. To repeat a homework : Repeat Differentiation | Evaluation | Observance of technician of safety | Tasks from simple to difficult (on Блуму) 1.Work with " by a physical alphabet" (denotations of physical sizes, units). 2. conclusion of units (system SI) 3.conclusion of formulas at the decision of tasks. | Verbal mutual evaluation; Criteria | Descriptors | points | 1.Различать physical sense of concept of mass, closeness, formulas of mass, closeness, units. | mastered: concept, formula, units. | 1 1 1 | 2.
