### Modelling the Seasons

This resource provides a scaffold for students to undertake a simple experiment. Students use a world globe and a heat lamp to investigate how the tilt of the Earth’s axis causes the seasons.

### DIY Sun Science - iTunes app

Try some hands on investigations that relate to learning about the Sun. Follow step-by-step procedures, read through explanations to find out why things happened and also view related video clips. Free when reviewed on 12/5/2015.

### ACMF: Effects of selective breeding

This resource is a web page providing information about an experiment on the growth rate of different chicken breeds carried out by students at James Ruse Agricultural High School in NSW, which shows the influence of selective breeding on chicken weight. It includes a side-by-side column graph comparing the weight of egg ...

### Stickleback Evolution Virtual Lab - iTunes app

Enter this virtual laboratory and conduct experiments to investigate genetic variation and evolution of populations of the three-spined stickleback fish. Students analyse fish and fossillised specimens, construct tables and graphs, and interpret their analysis. There are also instructive tutorials, videos describing stickleback ...

### Experimental probability

This is an interactive resource that enables students to conduct virtual probability experiments using a spinner or a pair of dice. The student can manipulate the relative sizes of the different coloured segments of the spinner or the numbers on the faces of the dice to investigate the effect of these changes on probability. ...

### Spinner

This is an interactive resource that investigates experimental and theoretical probability based on a spinner. The student can select the number of segments on the spinner and simulate spinning the spinner with a mouse click. The outcome of each trial is recorded in a table along with a comparison between the cumulative ...

### Racing game with one die

This is an interactive game that investigates probability by simulating a two-car race, in which the movements of the cars are based on the roll of a die. Cars advance when certain numbers are rolled, and the student can experiment with probability by selecting which car moves forward for a given outcome of the roll of ...

### Bryozoan skeletons in acidic solution

This is a colour photograph of two tubes, each containing bryozoan skeletons in acidic solution. The photograph depicts a scientific experiment investigating the effect of different pH levels on bryozoan skeletons. (Classification - Phylum: Bryozoa)

### Mapping our waterway

This is a 29-page PDF unit of work for year 7 that comprises a two-part teaching and learning sequence on waterways. 'Assessing the health of the waterway' involves students collecting data to assess the water quality of a local waterway, while 'Creating a map of the waterway' involves them using Google maps to display ...

### Solvent extraction of copper

Carry out an experimental investigation like those used in industrial laboratories. This is a fact sheet giving information and instructions for an experiment investigating the recovery of copper metal from ore using solvent extraction. It includes background information on the industrial process and chemistry involved, ...

### Fruitcake mining

This is an activity sheet providing instructions for a simulated mining experiment using pieces of fruitcake. Students use various tools to remove different fruits, each representing different minerals, from a piece of fruitcake which represents the mine site. They are then required to rehabilitate the 'mine site'. The ...

### Digestion Experiments 2

Students use this resource consisting of ten slides with diagrams, written explanation and voice-over to understand that enzymes work best at a specific pH. There is a two-question quiz and a summary slide.

### Digestion Experiments

This resource consists of 3 sets of illustrated slides with voice over presenting detailed information and explanations of an experiment used to investigate the action of amylase on starch and the optimum pH for the action of protease on egg white protein. Results are provided and interpreted using tables and graphs. More ...

### Experiments that compare Inhaled Air and Exhaled Air

Students use this resource consisting of seven slides with diagrams, written explanation and voice-over to understand the procedures to compare carbon dioxide levels of inhaled and exhaled air and to detect presence of water vapour in exhaled air. It relates the change in exhaled air to respiration. There is a two-question ...

### Digging into Science- where science fits in paddock to plate

This is a resource about the scientific roles involved in the steps of the farm to plate process. It presents the current issues that Australia faces in food production and why science is important in every stage of the food production process. The resource is presented as a teacher guide and includes: learning outcomes, ...

### Experiments to see if Chlorophyll and Light are Needed to Make Starch

Students use this resource consisting of eight slides with diagrams, written explanation and voice-over to understand that chlorophyll and light are needed for a plant to make starch. There is a two-question quiz and a summary slide.

### Digestion Experiments 1

Students use this resource consisting of thirteen slides with diagrams, written explanation and voice-over to understand that enzymes digest foods so that they can be absorbed into the blood. There is a two-question quiz and a summary slide.

### The Conversation: research ethics collection

This is a series of short articles on the topic of research ethics and the scientific method. It includes ethics of social sciences, animal research, clinical trials, and legal issues. The articles are written in plain language and are authored by experts from universities in Australia and around the world. The articles ...

### Density Simulation (sk-Intel)

This resource is in the style of an 'authentic' scientific investigation. The investigation is set in a crime lab where finding the densities of the various items can solve the crime. The tool enables students to explore mass and volume for a variety of solids and liquids and hence determine their densities.

### iPlan

This resource contains ten IWB flipcharts as well as Flash alternative exercises and models how to plan a scientific investigation, choose the right equipment and follow safe working practices.
