BAŠ JE IN BITI GREEN 4.0 - 17. CILJEVA ODRŽIVOG RAZVOJA

U sklopu eTwinning projekta: Baš je In biti Green održat će se mnoge aktivnosti o dekodiranju 17 ciljeva održivog razvoja te će se o jednome cilju podrobnije izvijestiti na prikladan način. Pomoću digitalnog alata Genilly dekodirat će se interaktivna slika, slagalica.

U okviru eTwinning projekta Baš je IN biti GREEN 4 izučavati će se tema o dekodiranju i ciljevima održivog razvoja.

Zadatak je dekodirati 17 ciljeva održivog razvoja. Zadatak će biti postavljan u interaktivnoj slici u digitalnom alatu Genially u obliku slagalice. Brojevi i ciljevi održivog razvoja (napissani na engleskom jeziku) kodirani su 7 -znamenkastom ASCII kodu (američkom standardnom kodu za razmjenu informacija).

Treba fotografirati  postupak dekodiranja (dekodirane brojeve i ciljeve održivog razvoja i završnu slagalicu).

Nakon dekodiranih  svih 17 ciljeva treba odabrati jedan cilj održivog razvoja, istražiti ga i prikazati u digitalnom alatu po vlastitom izboru. U digitalnom radu treba integrirati i naziv cilja koji je prikazan kodom.

Unplugged coding in a "Horizontal Shot"

Coding of movement in a horizontal shot

Objective of the activity:

• Through simulation, students will understand how the speed and position of the body change in two directions: 

* horizontally (uniform motion) and 

* vertically (uniformly accelerated motion) during a horizontal shot.

Required materials:

• Paper and pencil

• A rectangular space divided into a grid (eg square tiles, strips)

• Cards with instructions for the steps (prepared by the teacher)

Activity in groups (4-5 students per group):

1. Setting up the space: The classroom or the space where you will perform the activity should be divided into a grid of squares. 

Each square represents the time-equivalent size of the distance traveled in a unit of time (eg 1 second), and the body (projectile) travels a certain distance in the horizontal and vertical directions at each step.

2. Individual roles:

o Students are divided into groups, with one student representing the projectile (body), another student controlling the time (time controller), and the third student in charge of the instruction cards (card holder).

3. Simulation of a horizontal shot:

The body (projectile) moves horizontally at a uniform speed (one square per step), while in the vertical direction it covers a distance that increases rapidly.

o The instruction for each step (second) reads:

 Horizontal shift: constant (e.g. 1 square)

 Vertical displacement: increases according to the formula s = 0,5*g*tˆ2

 (where g ≈ 10 m/sˆ2, and t is time in seconds).

• Step 1:

Move 1 square right, 0,5 square down.

(for t = 1 second, s ≈ 0,5×10×1^2 ≈ 5 m).

• Step 2:

Move an additional 1 square to the right, 2 squares down.

(for t = 2 seconds, s ≈ 0,5×10×2^2 ≈ 20 m).

• Step 3:

Move an additional 1 square to the right, 4,5 squares down.

(for t = 3 seconds, s ≈ 0,5×10×3^2 ≈ 45 m).

4. Table of steps:

Students write their steps in the table so that they can analyze the motion.

5. Analysis and discussion:

After the simulation, students analyze the data values ​​in the table and observe how the body's motion changes in both directions.

Conclusion:

This activity allows students to simulate a horizontal shot through unplugged coding and understand the independence of motion in two directions.

Through an algorithmic approach, students gradually build an understanding of how gravity affects acceleration in the vertical direction, while horizontal motion remains constant.
