Kym Wright combines hands-on investigations with the study of factual information in her topical studies. Among her present titles are Bird Unit Study, Arachnids Unit Study, Color Adventure!, Library: Learn and Do Unit Study, Microscope Adventure!, Botany Adventure!, Goat Unit Study, Sheep Unit Study, Photography, Poultry Unit Study, Turtle Adventure!, and Volunteer Unit Study.
Most of these stretch easily for use with different age students. As you might guess from some of the titles, units on topics such as sheep and poultry will work best for those who live in rural areas and can raise farm animals or easily observe them.
These are very detailed studies that include experiments, projects, reading, writing, and numerous other activities. Kym provides lesson plans that you can use as is or adapt to suit your situation. You will need to find some of the resource books she recommends for each topic. Studies also feature related Scripture verses.
