Ina Kulczynska's store:
This science journal can be used through the year, as it is adaptable to any strand of the curriculum. I suggest printing off the second page (My observations) at least 5 times for each student, as it will encourage their own observations, even outside of school.
It makes an excellent assessment tool, provided that you have explained to your students that it is to be used strictly for science discovery and experimentation.
I hope your students will enjoy this free style of a journal.
