Duckweed Population Study—
Student Laboratory Kit
By: The Flinn Staff
Students can witness a population explosion right before their eyes as they nurture and experiment with living duckweed plants. Students start with a small number of plants and watch them reproduce vegetatively into a large matted colony, too numerous to count. Students can design their own experiments to determine factors that can affect the rate of the population explosion.
Complete for 30 students working in pairs. Duckweed cultures are available separately.
Estimating Populations—Super Value Kit
By: The Flinn Staff
Students receive firsthand experience using the mark/
recapture method of counting a population, a technique often used by ecologists and wildlife biologists. First, students capture individuals in their simulated population and “tag” them. Then the organisms are released back into the population. After multiple trials of marking and releasing, students mathematically predict the size of the population. Lastly, students count the actual population and determine the reli- ability of the mark/recapture technique. Includes 3,500+ pop beads and complete teaching instructions.
Super Value Kit is complete for 30 students working in pairs. All materials are reusable.
Stick Bug Survival—Super Value Kit
By: The Flinn Staff
A fantastic hands-on activity where students learn about natural selec- tion, gene pool, population size and predator/prey relationships. Stick bugs live in a stick forest and tend to blend in with their stick forest surroundings. Forceps birds love to eat stick bugs when they can find them! What happens to a population of stick bugs over several genera- tions? Who survives? Who thrives? Your students will have fun and remember key principles of survival after participation in this hands-on activity. Working in teams, students will play the role of forceps birds and go on feeding frenzies. Each forceps bird has its favorite variation of stick bug. Once eaten, the stick bugs are not returned to the popula- tion. Only those that survive are allowed to reproduce. Which ones have the greatest survival rate after the first generation? What happens to the makeup of the population? What happens to the population after many generations of feedings? All these questions plus many more will be answered.
Super Value Kit is complete for 32 students working in groups of four. All materials are reusable.
