Using an air-rifle in schools to demonstrate velocity of a bullet: We are wondering what rules there are around using a BB pump rifle in schools to demonstrate velocity of a bullet. I expect the safety aspects are too great to perform anymore but am hoping that you may have some information for us.
Information for the use of lasers in schools.
This set of downloadable documents detail standard operating procedures for the use of lasers in schools.
The procedures are set out in three parts:
The accompanying example risk assessment should be used as a guide only, and users should consider risks and safety measures in their local environment before proceeding.
This downloadable resource looks at the conservation of energy in an oscillating spring.
The resource is a student worksheet of questions relating to a short practical activity about the conservation of mechanical energy during the motion of an oscillating spring.
The document includes energy graphs, which can be quite challenging.
The answers are provided to assist teachers and students with understanding.

This downloadable resource tests knowledge on the conservation of energy.
The resource is a student worksheet of questions relating to the conservation of energy, specifically relating to mechanical energy being the sum of kinetic and gravitational potential energies.
The accompanying PDF shows the full working and answers to assist students with formulas and calculations.

This online resource investigates Newton's second law of motion.
The resource is an interactive web page that focuses on the concept of Newton’s second law and the link between mass, acceleration and net force.
Interactive quizzes enable students to immediately practice what they learn. Further, 'Check Your Understanding' problems appear at the bottom of the page for students to try.
It also has links to Student Extras and Teacher’s Guides and links to follow-on tutorials are also provided.

This online resource deals with the conservation of total mechanical energy.
The resource is a tutorial on the concepts of the conservation of total mechanical energy (TME) during energy transformations and covers the examples of a pendulum, a roller coaster and a ski jumper.
It also has an accompanying illustrative animation and plenty of practice applications for students to try.

This online resource looks at the effect on springs of falling masses.
The resource is a simulator that allows students to study the effect on springs of falling masses under various conditions.
Different masses can be added to up to 3 springs and their stiffness and damping can be adjusted.
The springs are extended and released and their motion can be analysed via energy graphs which show kinetic, potential, thermal and total energy.
These online interactives demonstrate the interaction of forces.
The resources are a number of downloadable interactive simulations that help explain the various forces acting on moving objects in terms of the mathematics involved.
Explore the forces at work when you try to push different objects along a flat surface. Create an applied force and see the resulting friction force and total force acting on the object.
See charts that show the forces, position, velocity, and acceleration v time.
This online resource is a good demonstration of the transfer of energy.
The resource give details of a teacher demonstration on the energy transformations involved in a collision between a basketball and a tennis ball.
A tennis ball is positioned on top of a basketball and the two are dropped from a height. The tennis ball is spectacularly propelled high into the air when they collide with the floor.
The resource also gives a detailed explanation of what’s going on and how to take things further.
This online resource helps demonstrate conservation and transformation of energy.
The resource details a hands-on activity where students can build a simple wind-up 'race car' that demonstrates principles and use of stored mechanical energy.
The race car is made from easily obtainable household materials.
