This PDF article is about photoluminescence.
The resource explains photoluminescence, which is created by the change of energy of electrons.
The article also suggests a series of questions that can be used by students to plan simple experiments using glow in the dark toys.

This online resource looks at the sensitivity of human hearing.
This free online hearing test measures the relative sensitivity of your ears at different frequencies using the audio capabilities of a computer.
It produces equal loudness contours or hearing sensitivity curves—the frequency response of a person’s ears and has been successfully trialled in a classroom situation where each student used their own ear plugs and computers.
The website also has a multimedia tutorial on the operation of the voice and hearing.
This online resource investigates different sound frequencies.
The resource is an instructional guide for building pan pipes made of drinking straws to demonstrate that different musical notes have different frequencies.
The instructions include how long to cut each straw for particular notes, and a guide to playing basic nursery rhymes using a number system.
This activity would make a good introductory lesson to sound waves or an extension for more able students to discuss frequencies and resonance. It should take approximately 30 minutes.
This online resource demonstrates how to simulate the rock cycle.
The resource is a step-by-step YouTube video guide for using wax crayons to demonstrate erosion and creation of sedimentary rocks as well as the link between sedimentary and metamorphic rock.
A worksheet is also available for students to use when replicating this task in class.

This online resource looks at plate tectonics.
The resource is a Youtube video where the presenter shows 5 ways to model the layers of the earth, how tectonic plates move across the Earth’s surface, and the types of boundaries that exist between the plates.
Included are a number of small demonstrations that cover all aspects of the above and teachers can handpick the activities which best suit their class and integrate these into their course.

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 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.

This online resource investigates Newton’s second law of motion.
The resource is a student practical activity. Students time how long it takes a dynamics trolley to travel a set distance along a runway under a given force.
The force is then doubled and the time re-measured. Mass is then doubled and the time re-measured.
Teaching notes are included and related experiments are also listed.

This online resource shows how to build a double pendulum system.
The resource details a student practical activity that focuses on how to build a double pendulum system to illustrate the conservation of energy within such a system.
The resource has an explanation of how it works and some extension activities.
