Time4Learning is an online student-paced learning system covering preschool through middle school. It is popular as a fourth grade homeschool curriculum, for afterschool enrichment, for remediation, and for summer study.

The lesson plans below provide a detailed list of the fourth grade science curriculum, with brief activity descriptions and learning activity (LA) numbers. Additional resources related to fourth grade science are also provided, below.

Students enrolled in fourth grade science will have access to both third and fifth grade science lessons as part of their membership, so they can move ahead or review at their own pace.

If you are just learning about Time4Learning, we’d suggest first looking at our interactive lesson demos. Members often use this page as a resource for more detailed planning, to choose specific activities using the activity finder or to compare our curriculum with state standards.

Lesson Activity Finder Tool

The lesson activity finder is one of the many helpful tools that Time4Learning offers its members. The activity finder is a shortcut that makes it easy for parents to preview lessons or find extra practice for their child.
Every lesson in the curriculum has a unique activity number, referred to in the lesson plans as an “LA Number.” These numbers can be found on either the scope and sequence pages or the lesson plans in the Parent Dashboard.
The activity finder can be found in the lower left hand corner of the Student Dashboard. To use it, members simply log in to their child’s account, type the Learning Activity (LA) number of a lesson into the Activity Finder and click “Go” to open it.
