For a week, the head segment didn’t change in size at all, and remained 1 mm long (the length it was when I first cut the worm). However, after 1 week, the body segment had grown one millimeter, from 3 mm (original length) to 4 mm. After 2 weeks, the head segment had grown to 2 mm, and the body segment had remained the same at around 4 mm. The slight changes in the two halves go along with my predictions, and show that while the halves did regenerate, it was in very small amounts. This experiment went along with what I had initially expected, and proved my overall hypothesis and predictions. Overall, this experiment was a success regarding observing worm regeneration and proving a hypothesis. I predicted that my worm’s small size would impact the amount of regrowth it would experience, and my results prove that both segments only grew a maximum of 1 millimeter over the course of 2 weeks. After severing my planarian worm in half and recording the results of it’s regeneration, it’s safe to say that these worms definitely regenerate, but because they come in different sizes it’s harder to observe large changes over extended periods of
