Emma and I really had a great time reviewing ‘Puffer Fish’, a unit study from The Curiosity Files published by The Old Schoolhouse. We’ve done unit studies in the past, but we haven’t ever done one by The Curiosity Files. We are both big fans, and would definitely do another.
This is a complete unit study. I enjoyed having the information all in one place at the beginning of the unit. From there, Emma was able to choose a few activities to go along this the study. She chose to do some copywork, a math exercise, and of course, the art project (a paper mache puffer fish which is still in progress).
Emma put her measuring skills to good practice while comparing the sizes of various species of puffer fish.
There were a lot more activities to choose from on all different levels. The recommended age range for this unit is 8-13. I used it with 7yo Emma with no trouble. I did pick the activities geared toward the younger end of the range. I could have easily used this with my middle-schooler, as well. However, he was pretty content with his own ongoing science lessons, and he chose not to join us.
There are many more titles available in this series. You can choose to learn about the blue-footed booby, dung beetle, platypus and more. With a price of $6.95, this is a great, inexpensive science supplement!
