I thought this textbook was a good introduction to chemistry and physics, but I wouldn't say it is a k-5 book. I'd recommend it for an advanced 4th grader or 5-7 grades. My kids loved the experiments but their eyes glazed over during the readings.
Overall, this was a good curriculum. It would be nice if there was a Middle School supplement with more advanced activities for older kids who want to go just a bit deeper but are in between the elementary age and high school. I spent a LOT of time researching and coming up with my own activities to make it more interesting for the older crowd.
We have used every single Apologia Science product up through High School Biology and have not been disappointed with a single one of them... Chemistry and Physics was fantastic! We loved the experiments and conversational style of the curriculum. My son actually reads this on his own and then we discuss what he read. He was so excited because he got to cover Chemistry before his older high school brothers covered it! LOL!! It got all 5's from my son!

I used the Young Explorer's Chemistry and Physics with my then 4th & 6th graders. They loved all the hands on experiments and color photos. The notebooking journal was a wonderful resource to help both age levels record what they had learned and give them a fun way to review.
I appreciated the premade material lists (by lesson). This allowed me to be prepared each time instead of having disappointed kids when we didn't have X, y or z.
Grade levels used
I was able to teach mutliple age levels from the same book and know that the younger ones were "getting it", and the older ones weren't getting bored.
We are just finishing up with this study. The kids really enjoyed the lessons and activities. I love how the kids can read the lesson on thier own and then come to me with what they have learned. We did not use the journal with this study. Instead we used the free printables that you can print from Apologia book extras. This work well for us.
