With 30 pages for observations and experiments, plus 30 pages for science vocabulary, our handy journal is the perfect way for children to record science discoveries! Kids just follow simple prompts to record the results of up to 15 different experiments—including what they did, what they saw, what happened and what they learned—then list and define new vocabulary words! The spiral-bound journal is 60 pages and measures 7 1/2" x 10".
