5. At Last! After drilling thorough my finger, banging my thumb, and making twenty-five trips to Menards, Lowes, Wal-mart, and Rural King, I was finally able to plant my garden.
6. Questions How do the plants grow vegetables? Why do we need bees? How do seeds get from one place to another?

12. How Seeds Travel 1. Gather five seeds of different sizes and shapes. 2. Describe your seeds on a chart. 3. Next to each seed description, predict whether that seed could travel by wind, water, or hitchhiking. 4. Try out your predictions using the tests below. Record your answers on the chart. Wind Test: With an adult's help, stand a fan on a chair so that the top half sticks over your desk. Use tape to make a starting line 25 cm (10 in.) away from the fan. Place seeds on the starting line. Turn the fan on at medium speed for 20 seconds. Measure how far your seeds traveled. A seed passes the Wind Test if it blows more than 1 m (40 in.) away from the line. Water Test: Fill a small container half full of water. Drop the seeds into the water and stir. A seed passes the Water Test if it floats. Hitchhiker Test: Place a seed on a table and cover it with one test material. Gently press down on the material with your palm. Lift and check -- does the seed stick to the material? Repeat with two other test materials. A seed passes the Hitchhiker Test if it sticks to any test material. Wrap-up: Were you surprised by any of the ways your seeds could travel? Look at the seeds that passed the Wind Test. How are they similar? (Hint: Are they all small? Big? Do they have the same shape?) How are these seeds different? What do the floating seeds have in common? How about the hitchhiking seeds?
