Most plants reproduce using systems that include flowers and seeds. In this outdoor investigation, children observe, collect, and classify plant seeds.Gather a collection of seeds from a wooded area. Try using one or more of the following methods:

• Drag an old blanket or fuzzy cloth behind you on the ground.
• Place a large, old, wool sock over hands or shoes to see what you can pick up.
• Wear bracelets made of masking tape (sticky side out), to hold the seeds you find.

Have children examine their seed collections and invent a system for sorting or classifying them. Explain that plants have developed many different methods of seed dispersal, to ensure the success of their species. Some seeds need the help of other external variables to disperse.

Answers: ACORN, SAMARA, CRANBERRY

These three examples represent only a few of the many ways that seeds can be dispersed. Conduct your own research to explore more -OR- consider challenging children to design their own seeds, complete with specialized dispersal mechanisms. To make a functioning model, try using a dried lima bean with different art materials (feathers, toothpicks, cardboard, cotton balls, string, rubber bands, etc.) to design a new type of seed. What dispersal method will it use?

The scientific name of blackjack seed is Bidens pilosaL. The spread of the seed is due to pollination mechanism and distinctive dispersal. The shape of the seed is long, slender, lanceolate type. Due to such structure they easily get attached to the clothes of human, animals or even carried away by water or wind. BlackJack regular seeds are well suited for the SOG and SCROG growing methods. Indoors, the plant will reach a height of 130 to 170 cm and yields up to 500 gram per m2.
