· Janene · Homeschooler
“The students liked discussing orchids and other plants they are familiar with. They were surprised that not all plants need a lot of water and sunlight! They love the idea of decorating the grass heads but I decided not to use class time for an activity that is not educational so we only did the results portion and I sent the rest home.”

Prep Instructions

In this activity, students need the Grass Head and the worksheet that they completed in the previous lesson.

Prepare To Discuss the White “Hair” Surprise

If you or your students examined the Grass Heads as they were growing, you may have seen something that surprised you. In addition to the green grass hair, there were white hairs growing downward. What are those white hairs?

Your students may notice that the white hairs always grow DOWN. That’s because the white hairs are roots! Remind your students of what they saw in the root viewer — roots grow down, looking for water.

Grass Heads With Style (Optional)

If you have time, students can personalize their Grass Heads, adding accessories and clothing. If you decide to do this, you’ll need some craft supplies.

For more on the possibilities, check out the Grass Heads With Style activity extension.

Transport the Grass Heads Home (Optional)

If students want to take the Grass Heads home, you may want to give them a paper cup to put it in to make transportation a bit easier.
