The Draw and Explore Science series is a great way to combine art and science. A short description of tropism, four main types of tropism, and seven different methods of seed dispersal is given. Each is followed by a related image on a grid. Next, students can do one or all of the assignments that follow. They can draw half of the image in a grid that shows the left half of the picture, half of the image in a grid that shows the right half of the picture, or the entire image on an empty grid. This makes the unit completely flexible for both left-handed and right-handed students. Fifteen review questions and an answer key are also included. Key vocabulary terms studied are tropism, geotropism, hydrotropism, phototropism, and thigmotropism, as well as the following seed dispersal methods: gravity, animal ingestion, animal fur, water, explosion, wind, and fire-mediated. 35 pages total. Ages 8-13.
