Using toothpicks, straws, or tubes of rolled up newspaper, learners create 3-dimensional models to illustrate the basic structure and function of the cell membrane, and place an object inside to represent the cell nucleus. This activity can be used in conjunction with the Observing Cells and Single-Cell Life activities from the same source. This activity can be found on pages 20-21 of the activity guide. Less

In this activity students examine a variety of seeds, describe them, and determine how they are dispersed. Students investigate seed dispersal mechanisms. Students, working in pairs, create and test a wind dispersed seed that they have designed themselves. Students are limited to using a single piece of white paper, one lima bean to represent a seed, tape and scissors. Seeds are tested by dropping them in front of a window fan and recording the distance they travel. Repeat trials are conducted, averages calculated, and class data recorded. Students examine the features of successful seeds and redesign their seed to try to increase the distance it can be carried by wind. Results are analyzed and comparisons made to natural phenomena.

By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from predators and weather. Learners consider why dispersal or spread of seeds is important to the survival of plant species as they identify seeds that fly, seeds that float on air, seeds that cling to other things that move, and more. This activity can be done in conjunction with the Local Field Guide activity from the same source, and is great for an outdoor field trip. This activity can be found on pages 26-27 of the activity guide. Less

In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them. To understand natural adaptions that let seeds and fruit be dispersed, learners make modifications to dried beans and peas so they could be dispersed by natural forces like water, air, or an animal moving from one place to another. In the "Seed-Go" Game, learners match ways that seeds are dispersed, to fill rows on the game board. Less
