Research hypotheses force scientists to be very clear to themselves and their colleagues about exactly what the explanation is that they are testing, the general method they are using to test it, and the prediction they can make if their explanation is reasonable. If birds use day length to time their movements north in the spring while their insect prey respond to warming spring temperatures, and I record the daily number of birds and insects in a forest for several spring seasons in a row, then in early springs the birds will arrive after the insects have already peaked in abundance while in late springs the birds will arrive before there are enough insects for them to eat.
But discovery science can generate hypotheses.
Marsh grass growth is limited by available nitrogen Miller and Levine This misunderstanding that has been born out of science education is not new. Some scientific pursuits are based in discovery science, in other words, looking for relationships in nature or simply measuring and describing things in nature.
We more specifically call this kind of statement an explanatory hypothesis. Continue with a specific example: As students come up with explanations for what they observe or wonder about, teachers should insist that other students pay serious attention to them. The ecologist may explain this observed pattern with the hypothesis that the birds and their food resources, usually insects, are responding to the same environmental cues warm spring temperatures.
Do not tell anyone what is written on the index card. Go through the questions the kids have come up with and point out the difference between observations and inferences.
The problem is the reverse: In early or late springs, the birds will arrive at the same time as always, while the insects will appear either early or late, depending on the timing of spring. Notice how the teacher reinforces to the student that the hypothesis is an explanation.
Conclude the lesson by telling students that in the real world no one has the cause of a disease written on a card.
Have the students keep a journal, writing down their search, both failures and success as well as their finds. Ask students to note the number written on the index card and write that number on the lower right corner of their worksheet.
In these cases, asking students to write hypotheses results in students writing predictions, or just being really confused. Assessment Assess student understanding by their participation in the class discussion and their contribution to their Epi team. Here you can make up an experiment for them or look through science books or the Internet to find one that is appropriate for your age group.
