If The Shoe Fits

Some sports are played inside, some outside. Some are played on courts, some are played on grassed ovals. Some sports need shoes with lots of friction, some want only a small amount of friction. This has led to a wide variety of shoes being developed by manufacturers to suit a range of conditions. This investigation is an open-inquiry exploration into the dynamics of friction, by looking at different shoes and surfaces. It is safe and inexpensive to conduct in the classroom, and can even be done in the home. It presents a real-world problem and incorporates sport science to engage a wide cohort of students.

The Role of Teeth

This investigation is designed for students to learn about the role of teeth through studying how the concepts of surface area and rate of reaction apply to their function in digestion. Students enjoy this experiment as it gives them a real world example of these chemistry principles. Mechanical digestion is a physical process where food is broken up into smaller pieces, whereas chemical digestion involves the action of different chemicals breaking certain bonds within the food molecules in order to change them into the simplest form possible.thumbteeth

Crash Test Dummies

One of the key elements of modern automobile design is safety. Forty years ago, cars were designed to withstand a crash with as little damage to the car as possible. Now cars are designed so that the car takes as much damage as possible, leaving the driver and passengers safer during a collision. In this activity, you are an automotive test engineer. Your task is to investigate what happens to someone in a car during a crash. You will do this by taking high-speed video footage of different kinds of crashes and examining what happens to ththumbteethe occupant during the crash.

 Food Tests

Nutrients are chemicals found in the food you eat which supply your body with energy for growth and repair. Some nutrients are also used to build essential structures in your body. The main nutrients in food are called the macronutrients, which consist of carbohydrates (e.g. sugars and starch), proteins, lipids (fat). The minerals and vitamins in food are also essential for life. We can test for the presence of these important compounds by using chemicals that react in predictable ways in the presence of them. We will bethumbteeth testing food samples to find what their nutritional composition is.

Swings and Pendulums

Swings can be a lot of fun in the playground as you experience the thrill of falling towards the earth, but have you ever wondered about the science surrounding them? Play swings are a type of pendulum, which describes a weight suspended by a string from a fixed point. In this investigation, students will be able to examine the physics behind pendulums. An exploration into pendulums offer students a great basis in concepts found within the ‘Forces’ unit. This investigation looks at the mechanics of a pendulum and asks sthumbteethome foundational questions about how they work. This investigation has been designed to be flexible and open enough to cater for students in grades 7-10.

Energy Transformations

Energy is observable in many forms and it can be transformed from one form to another. Energy is neither created nor destroyed; when energy changes in form the total amount of energy remains constant. In other words, even though energy degrades and dissipates, it is never destroyed. Throughout this investigation you will explore energy transformations and transfers. Potential energy to kinetic energy is the most common transformation, such as ball rolling down a ramp.  There are other forms of energy such as light, chemical, sound,thumbegg heat, elastic, nuclear and electrical.

Making Chocolate Crackles & Sherbert

This experiment is used to study the chemical changes happening when substances react and form new substances. During the course of the experiment, students will be able to compare the physical and chemical changes and identify how substances react to heating, cooling and dissolving. When two substances are mixed together, they can react chemically forming new products. For this to occur some bonds will break and new bonds will form changing the chemical composition of the reacting substances. The new product can have a different colour, smell or state. It may also release heat or absorb heat, making the contents feel warmer or cooler. Today you will investigate chemical changes by mthumbteethaking yummy chocolate crackles and sherbet!

 Electric Cars

Electric devices are part of our everyday lives. However electric cars are not widely used because of limitations in battery technology. In this investigation you will assemble a model electric car and use it to explore the differences between parrallel and series circuits, with different numbers of batteries. You will find out what results in the fastest electric car,thumbteeth the result may surprise you!
