The ‘Investigating in science’ strand

The nature of science is concerned with science as a way of thinking, but this can’t exist in isolation, so the New Zealand curriculum document includes three other substrands of the nature of science to embed it within.

Scientific investigations do not just take place in laboratories. Scientists carry out their research in many places. Here, Dr Jesse Conklin is carrying out field work as part of his research into migratory birds. Jesse hoped the inflatable crane decoys would attract godwits but the godwits had other ideas!

The ‘Investigating in science’ strand of the curriculum is one of these three other substrands.

Most science curriculum documents would call this strand ‘scientific inquiry’ rather than nature of science. The two main ways this substrand can embed and deepen nature of science understanding are by:

• giving students first-hand experience

• drawing attention to nature of science aspects in students’ own investigations and in the investigation of scientists.

First-hand experience

Science and mātauranga pūtaiao use investigations to collect data and help make sense of the world around us. It is one thing to tell ākonga that scientists carry out science in a whole lot of different ways. It is even better to support this statement by giving students first-hand experience of a myriad of different ways of investigating.

Engaging students in a wide variety of investigative processes will help debunk the myth of there being one ‘scientific method’ that scientists and kairangahau Māori follow.

The scientific method, as far as it is a method, is nothing more than doing one’s damndest with one’s mind, no holds barred. In short, science is what scientists do, and there are as many scientific methods as there are individual scientists.

All learners – from the early years to high school and beyond – are able to gather data. The article Investigating in science unpacks what this might look like in the classroom. It is also really valuable for students to see scientists and kairangahau Māori themselves carrying out a wide range of investigative approaches.

The following interactive covers a range of scientific approaches along with helpful videos and links to practical resources.

Bringing scientists into the classroom

It is also invaluable for students to see scientists themselves carrying out a wide range of investigative approaches. The Science Learning Hub provides this opportunity by showing scientists engaged in many different types of investigative research. Videos of scientists also enable students to see themselves in science.

Additional resources

The Hub has a huge range of resources. Below is a selection of resources that feature different types of investigative research.

Making it explicit

Whether the students are engaged in investigations first-hand or are watching videos of scientists and their research, we need to keep drawing students’ attention to learning about science as well as the doing science in these investigations. They should see that, far from there being only one nice tidy linear scientific method that all scientists follow, in fact, investigating in science is often messy and circuitous. They should see tenets of the nature of science in their own wide range of investigations and in the even wider range of scientists’ investigations to which they are exposed. 

Science is said to proceed on two legs, one of theory and the other of observation and experiment. Its progress, however, is less often a commanding stride than a kind of halting stagger – more like the path of the wandering minstrel than the straight-ruled trajectory of a military marching band. The development of science is influenced by intellectual fashions, is frequently dependent upon the growth of technology and, in any case, seldom can be planned far in advance, since its destination is usually unknown.
