Theme of the lesson

Laboratory work 2 “Study of the flight distance-angle of departure relationship”

Learning objectives that are achieved in this lesson

To study the trajectory of a body dropped at an angle to the horizon

Success criteria

Students have achieved the objective if they are able to:

·         determine the range and maximum height of a projectile launched at an angle to the horizontal.

·         Determine the angle at which range of a body is the greatest

Language objectives

Subject-specific vocabulary & terminology:

Projectile, trajectory, launch angle, maximum height, acceleration vector, velocity vector, range

Useful sets of phrases for dialogue and writing: find the range of the projectile.  Determine the maximum height of the projectile.  Describe the motion of a falling body.

Cross-curricular links

Study of graphs and their gradients directly links with mathematics.  Projectiles have a long history and students will be familiar with cases from history class in which projectiles are used in battle.

ICT skills

Students will use calculators to model projectile motion.

Previous learning

Students have learned the kinematic equations and how to read graphs of motion in the previous lesson.  Additionally, students have encountered projectile motion in previous years.

(G) Laboratory work. Students will work in pairs.

 Safety procedures for carrying out laboratory work.

Purpose:to predict and verify the range and the time-of-flight of a projectile launched at an angle.

Equipments:

1)      ballistic laboratory gun;

2)      measuring tape with centimeter scale;

3)      Sheet of carbon paper;

The teacherwill walk around the class and monitors the performance of the work, providing support to those students experiencing difficulties (scaffolding)

Homework:

To write an essay about the usage of projectile motion in military:
1) modern time
2) Middle Ages period
3) ancient time (Greece and Rome)

Reflection: Students will respond to the following statements with a thumbs up/middle/down

ü  I know how to find the range and maximum height of a projectile launched at an angle to the horizontal.

ü  I know how to find the angle at which the body flies farther

Differentiation – how do you plan to give more support? How do you plan to challenge the more able learners?

Assessment – how are you planning to check students’ learning?

Health and safety regulations

Strong students will act as leaders in the pair, assisting their classmates in the setting up of equipment, calculations, and answering questions.

Students' answers and the conclusion of laboratory work

Students will be reminded of safety procedures and rules for using laboratory equipment.

Reflection
