This will link you to carolinascienceonline.org . I can't post the login and password due to copyright rules, but the students know them (Login hint: high school, Password hint: We are #1) I don't use this site much for two reasons. 1) This site is notoriously slow to load. 2) Middle schoolers are not permitted to take their Chromenbooks home. However, the entire book is availiable on this site. If your student has a zero for an extend your knolwedge assignment and for some reason or other has "lost" the readings, you can find them here. An additional benefit of this site is that a student can utilize text to speech features to assist in reading.
This is an accommodation option for unconfident readers. You select the orator ( I would recommend English, US, G or English, UK, Female). Then copy and paste the reading material into the box and press play. The orator will read to you with fairly natural cadence and get even most of the harder vocabulary words pronounced correctly.
