This video deals with acceleration due to gravity.
The video investigates whether the mass of an object influences how fast it falls.
Science ambassadors Bernie Hobbs and Ruben Meerman explore a variety of situations in their quest to discover what affects the speed of falling objects.

This video explains the concept of free fall.
The resource is a video in which Catalyst's Dr Derek Muller reveals why objects are apparently weightless in space.
The video first explores some of the common misconceptions people have about gravity and the scale of distances in space for objects in near-Earth orbit before explaining the concept of freefall, which gives rise to the apparent weightlessness of astronauts in space.

This online resource investigates the activity series of metals.
The resource details a laboratory activity where students investigate the displacement of four metals to determine the activity series for those metals.

This unit of work investigates heat sources and how heat moves from one object to another.
The resource is a Primary Connections unit that allows students to investigate the difference in conductivity of materials.
The unit shows how heat is important in many ways in our everyday lives, such as drying our hair, cooking our dinner and warming our water.
It also deals with the dangers of heat and how we react instinctively when we touch a hot stove or walk barefooted on hot sand.
This online resource details an investigation into reaction rates.
The resource is a web page which details an experiment where the effect of temperature on the rate of reaction between sodium thiosulfate and hydrochloric acid is investigated.
The web page contains a lesson plan along with teaching tips and a student worksheet.

This online resource helps students to investigate the catalytic effect.
The resource details an activity where students investigate the catalytic effect of different metals in solution and how they affect the speed of a reaction.
The resource contains a lesson plan, with teaching tips, and a student worksheet.

This online resource demonstrates the collision theory of chemical reactions.
The resource is a web-based java application that allows students to model the effects of temperature on the rate of collisions in a closed system to see how this affects chemical reaction rates.
Users can alter the number of particles in their model and change the temperature of the reaction, and by observing the simulation they can see how the number of collisions are affected.
See the Additional Information section about how to access the resource.
This unit of work looks at the differences between living things and non-living things.
It is designed to help teachers teach their students learn how to distinguish living things from non-living things, and group them according to their observable features.
Students can then use this knowledge to investigate the animal groups in the leaf litter of their own school grounds.
This online resource demonstrates the expansion of the Universe.
A balloon is marked with dots to represent different galaxies and as the balloon is inflated the distances between the galaxies and a 'home' galaxy are measured.
The relationship, that has become known as 'Hubble's Law', is further investigated by processing concrete numerical results.

This online resource explores the principles of chromatography.
The resource is a student hands-on activity that demonstrates that inks are made up of different compounds that can be seen using a simple form of chromatography.
