Teacher Notes

A. Prior to the lesson:

1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.

2. If their phone camera doesn't automatically detect and decode QR codes, ask students to

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

B. The lesson:

1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.

2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.

3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

C. TIPS / OTHER IDEAS

4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.

Questions / Answers (teacher reference)

Question

Answer

1. The word 'force' has many meanings in everyday conversation. In science, a force is a physical action. It is a push or a pull acting upon an object as a result of its interaction with another object.1.
2. When objects have forces acting on them they may begin to move, speed up, slow down or stop moving, change the direction of motion, change shape, or remain still.2.
3. Some forces make objects move because of a direct push or pull by another object. The objects have to touch each other or be in contact. These are called contact forces. Hitting a fly with a fly swat or hitting a hockey ball with a hockey stick are two examples of contact forces.3.
4. Some forces cause movement without contact or touching. These are called non-contact forces. An example is a mass hanging from a length of string. There is no contact force between the mass and the Earth - only gravity at a distance. The little chock that occurs when you scuff your feet on carpet and immediately touch a person is another example of electrostatic non-contact force.4.
5. One way to 'see' a force at work is to measure it. In a laboratory force is measured using a device called a spring balance. The unit used to measure forces is called the Newton. Its symbol is N. It is named after Sir Isaac Newton (1642-1727), who first described forces.5.
