For outdoor learning we were using our eyes and ears to find birds. 

Can we find more birds with our eyes or our ears? 

We set out to find the answer to this question by counting how many birds we heard in 2 minutes and then counting how many birds we saw in 2 minutes.

We did a tally chart to track. 

We compared.

"We heard many more birds than we saw."

We made some hypotheses as to why we heard more than we saw.
