The seeds of different species of plants need different amounts of light, temperatures, and moisture levels in order to germinate successfully. In the Seed Germination Gizmo™, you will perform a series of experiments to determine the best conditions for germinating three different types of seeds. 1. Look at the DESCRIPTION tab. How many seeds are in the germination chamber? 100 2. Click Play ( ), and observe the SIMULATION pane. A. What happened over the simulated five-day period? Some of the seeds sprouted and the other did not. 55 of the 100 seeds actually sprouted. B. How does the appearance of a seed on the SIMULATION pane change once the seed has sprouted? When it sprouts a yellow vine type thing emerges from the seed and points upward C. How many seeds sprouted? 55 D. How many seeds did not sprout? 45 [Show More]
