• TLF-IDM015808

Explore with the Surfing Scientist team what happens when metals are heated and cooled. Find out what happens to a metal ring when it is immersed in extremely cold liquid nitrogen. What do hinges on the Sydney Harbour Bridge have to do with all this? Find out.

• TLF-IDL1185

Run experiments in a plant research laboratory. Investigate the effects of different variables on the growth of peas. Research the answers to questions about how to achieve optimum hydroponic growth conditions. Examine the effect of key variables on growth: nitrogen, temperature, light intensity and light duration. This ...

• TLF-IDL13

Look at photos of active volcanoes. Direct a robot as it is lowered inside a volcano. Measure temperature changes and look at rock structures. Collect rock samples from the crater, vent, column and magma chamber. Match the samples with their original locations.

• TLF-IDL194

Explore weather variations in four different environments: desert, mountains, rainforest and polar. Dress a character in clothing suited to the weather conditions: sunny, windy, rainy or snowing.

• TLF-IDL3254

Explore how substances are affected by temperature. Notice that particles vibrate more as temperature rises. Observe that some solids conduct heat better than others. Note that solids expand when they are heated. This learning object is one in a series of six objects. The series is also packaged as a combined learning object.

• TLF-IDL4365

Listen to a conversation between a doctor and her patients. Find out what advice the doctor gives them to improve their health. For example, the doctor reports that a person has a high temperature of 39.5 degrees Celsius and directs the patient to take some medicine. This learning object is one in a series of four objects.

• TLF-IDL540

Run experiments in a plant research laboratory. Investigate the effects of different variables on the growth of lettuces, peas and tomatoes. Research the answers to questions about how to achieve optimum hydroponic growth conditions. Examine the effect of key variables on growth: nitrogen, temperature, light intensity and ...

• TLF-IDL8982

Explore the effect of environmental factors on the rate of photosynthesis in an aquatic plant. Manipulate environmental variables including light intensity, carbon dioxide levels, temperature, and the wavelength of light to find out how each affect the rate of photosynthesis. Record and analyse the results in tabulated ...

• TLF-IDR11939

This interactive is a simulation of an experiment comparing the change of temperature in two flasks, one filled with air and the other with carbon dioxide only. Lights above the flasks come on and simulate the change in temperature. Results are portrayed on a graph.

• TLF-IDR12175

This realistic mathematical investigation uses scatter plots to determine a relationship between latitude and average daily temperature. It includes a student worksheet with a table of data, a teaching sequence, teacher notes, assessment advice and ideas for extension. ICT could be used.
