Engineering, construction and structural design have come a long way since humans first got here. This clip looks at modern design and construction materials, and provides glimpses of the future, as technology and our understanding of environmental impact and sustainability shapes our approach. It examines preferred futures, modern techniques and materials, and provides an insight to the design and construction of Dubai’s towering Burj Khalifa. Show Less

Human structures must be designed to withstand a range of forces. Here, three types of forces causing stress on structures are highlighted – bending, torsion and shear. Each one is defined, and different construction techniques are examined, with a particular focus on bridge-building. This clip provides secondary and vocational design and technology students with an insight to how structural design and construction techniques overcome massive stress forces. Show Less

A number of different design and structural elements are used in constructions – from the most simple to highly complex. This clip explores three common construction elements – columns, beams and cantilevers – defining each and providing different examples of where they are used in a range of different structures. Secondary and vocational students of design and technology will find this a useful and engaging learning resource. Show Less

Over millennia, human-built structures have become bigger, more complex and quicker to build. A key to this has been understanding how forces behave. This clip looks at two types of opposing forces – tension and compression – defining them and presenting a range of real-world examples and how those forces impact on structural design. It is an ideal resource for secondary and vocational students of design and technology. Show Less

Newton’s three laws of motion are fundamental to many aspects of physics, including collisions. This clip covers the laws, explaining each and looking at how they apply to different examples of collisions. Calculations involving force, mass, acceleration and stopping time are applied to various scenarios. It is an excellent learning resource for senior level physics students. Show Less

Understanding the relationship between different variable quantities when objects collide enables us to explain and predict their behaviour. This clip looks at quantities including work, force, distance, mass, velocity and kinetic energy. Worked examples using different mathematical formulae are applied to everyday examples of collisions. It is a great learning resource for senior level physics students. Show Less

Calculating scalar and vector quantities is vital to understanding collisions. Using tennis court action, this clip examines various quantities including initial and final velocity, displacement, acceleration and time. A number of clearly worked examples using a range of mathematical formulae are provided, which will assist senior level physics students to understand the relationship between various scalar and vector quantities. Show Less

Collisions occur around us constantly. To know how objects behave when they collide, an understanding of some important concepts of physics is needed. This clip features many examples of collisions, and examines how applying Newton’s Laws of Motion, principles of energy and measuring variable quantities enable us to understand and predict the behaviour of colliding objects. It is an ideal resource for senior level physics students. Show Less

In this episode, we look at the 'joule', the unit for energy. We look at how much energy is stored in different foods by comparing apples and oranges (normally a no-no) and we discuss how much energy we need to do certain things including nothing much at all. We then explore the concept of energy balance and reveal the two simple rules for weight loss. That's right, these are only two! Show Less

In this episode, we introduce students to the concept of efficiency, which is a measure of how much useful energy you get out of something compared to the amount of energy that you put into it. We answer a bunch of questions including: How much light energy we get out of light globes compared to the amount of electrical energy that goes into them (Hint: it’s not much; they should be called heat globes!), how much kinetic energy we get out of cars compared to the amount of chemical energy that we put into them (Hint: it’s a bit more, but not that much more!), and how our arched feet make us the long-distance running champions of the animal world. This video is the most energy-efficient way of learning everything that you need to know about energy efficiency! Show Less

In Newton's Second Law, we answer the most important question that has ever been asked: how does a magician pull a table cloth out from under a dinner set? No, seriously, we look at the simple yet powerful equation 'F=ma'. Newton's Second Law tells us how to calculate the amount of force required to accelerat somthing by a given amount. Show Less

In Newton's Third Law, we look at that most poetic of all Laws: For every action there is an equal and opposite reaction. How does a rocket engine work? Why do guns recoil when fired? How do our muscles work? What propels us when we're swimming? And how exactly is gravity a two-way interaction? All these questions, and many more, will be answered in this excellent video.

In Newton's First Law, presenter Spiro Liacos is 'thrown forward' in a head-on collision, 'thrown backwards' when his tram takes off, and 'thrown to the side' when his car suddely turns a corner. But in fact none of these things actually happen! Using brilliant visuals, this episode looks at the fact that an object will remain stationary or move with a constant velocity unless a force acts on it. It also describes a number of different forces that affect our lives daily. Show Less

In a 100-metre sprint, when do athletes reach their highest speed? When do they accelerate at the highest rate and at what point, if any, do they stop accelerating? In Graphing Motion, we look at how graphs can help us better understand the motion of athletes, cars, and other things. Show Less

In this episode, we introduce students to the concept that acceleration is a measure of how quickly something changes its speed. We join James Bond as he falls out of an aeroplane without a paracute, splash into the water at 50.4 km/hr with present Spiro Liacos, and watch on helplessly as a truck runs off an unfinished bridge and explodes in a massive fireball.

A ride-on pallet jack is a potentially dangerous piece of plant equipment if not operated safely. They are very heavy even when not loaded and therefore have the potential to cause injury or damage at any time when moving. This snippet demonstrates the safe use of a ride-on pallet jack. Show Less

Pallets jacks are used to move a load that would otherwise need multiple people or a forklift to move it. Although a licence is not required, it is important to be trained in using a pallet jack prior to operating one. PPE should be worn when using a pallet jack. This safety training video snippet demonstrates the safe use of a hand pallet jack by a trained operator. Show Less
