The Family Science Packets are organized around key science concepts that are aligned with the National Science Education Standards and are composed of two major sections: Teacher Notes and Family Science Activity. Materials for families are provided in English and Spanish on the accompanying CD. Each activity identifies processing skills critical for student advancement including formulating a hypothesis, predicting, and collecting data. There are 20 activities equally divided into lower (K-1) and upper (2-3) primary grades. Grade level designations for each activity are suggested, though a teacher's use of the materials may be applied based on students' needs and interests as appropriate.
