This packet contains six science learning activities that can be used in agricultural education courses. The activities cover these topics: (1) determining the effects of soil drainage on plant growth and development; (2) determining the effect of soil compaction on plant growth and development; (3) inoculating legume seeds to promote nodule formation; (4) propagating plants; (5) determining the effects of rhizobium japonicum and nitrogen fertilizer on nodulation and plant growth; and (6) determining effects of frost/hail damage on plant growth. The lesson plans for the activities consist of the following elements: agricultural subjects and science principles included in the lesson, agricultural applications, student objectives, activity length, group size, vocabulary, materials required, instructional strategies and procedures (overview and results), key questions, and evaluation. One to three references are given for each activity, and each includes a data record and observation sheet. (KC)
