The Scientists/inventors bundle comes with 7 different scientists and yes, you can get through them all in one full school year. There are 8 lessons per scientist and the curriculum walks you through what to do each day. If you want to go through all of the units in one year I suggest doing a lesson twice per week. Of course you can do more/less depending on your schedule and how many you wish to complete as well. This curriculum is very flexible! Each day takes about 15-20 minutes to complete.
