The roly poly experiment, also known as the tumblebug or pillbug experiment, is a classic biology lesson that demonstrates the ability of certain animals to roll into a ball as a defense mechanism. Roly polys, also known as pillbugs or sowbugs, are small, terrestrial crustaceans that are commonly found in damp environments such as gardens and forests. They have a segmented exoskeleton and a pair of antennae, and they are known for their ability to curl up into a tight ball when threatened.
The roly poly experiment is often used to teach students about the concept of reflexes, which are involuntary responses to stimuli that occur without conscious thought. When a roly poly is touched or otherwise threatened, it will reflexively roll into a ball as a way to protect itself from harm. This behavior is known as tonic immobility and is a common response in many animals, including insects, birds, and mammals.
To conduct the roly poly experiment, students can collect a few pillbugs from their backyard or local park and place them in a small container with damp soil or a moist paper towel. The students can then observe the pillbugs as they move around the container and see how they respond when touched or threatened.
One variation of the roly poly experiment is to place the pillbugs in a small arena and introduce various stimuli to see how they react. For example, students could use a small stick or other object to prod the pillbugs and see how they respond. They could also try making loud noises or introducing other types of stimuli to see how the pillbugs react.
Overall, the roly poly experiment is a simple and engaging way to introduce students to the concept of reflexes and how animals use them to defend themselves. It is also a great way to get students interested in the natural world and encourage them to explore their local environment.
Roly Poly Adventures: Science Experiments with Pill Bugs
Number in Light Chamber Number in Dark Chamber Average of Pill Bugs in White Light Average of Pill Bugs in Dark 0 5 5 0. The little blue-gray critters that live under rocks and logs and roll into a ball when disturbed go by many names: roly-poly bugs, pillbugs, woodlice, tiggy-hogs, parson-pigs and their scientific name, Armadillidium vulgare. The pH of Hydrochloric acid, HCL, 0. We offer the freshest, nutrient rich and minimally processed ingredients with many health promoting benefits. They have an exoskeleton with plates. The Roly Poly has more health than a Interaction With The Player Roly Polys behave towards the player the same way they would to any other creature attacking them, chasing and attacking them via the same attacks.
There are plants that grow best when the soil is acidic, and there are some plants that grow best when the soil is basic. Julie Durr began her writing career in 2001. I learned a lot and spent time doing new things. We checked the next day and there were still many bugs there enjoying their food source. As terrestrial creatures related to marine animals, they need moisture to survive but cannot live submerged in water. Hydrochloric acid and Sodium Hydroxide have pHs at the extremes of the pH scale. Much like the habitat design activity, I had to source and test different materials to make sure that the activity would work for students when they did it in the classroom.
They breathe with gills, and therefore their habitats are places of high humidity. This was a very interesting activity to work on. A view of my office after spending a summer as a curriculum developer. Number in Neutral Chamber Control Number in Acidic Chamber Number in Basic Chamber Other Notes 0 10 0 0 Immediate Movement 0. The data collected in part three of the experiment did not support what was hypothesized.
The purpose of these pouches is to hold developing eggs and embryos. In our laboratory setting we were attempting to determine just how often the pill bugs would chose the moist setting over the dry one, and if they did settle in the dry setting would they group together to prevent moisture loss. After the ten minutes had elapsed, the ten pill bugs were returned to the stock culture. When organic matter decays, H ions are produced. However, the moment when I saw the roly polys actually walk through the tunnel like little pseudo-salamanders made all the hard work worth it.

However, the results suggest that pillbugs preference is for the more caustic environments over the environments that are neutral or acidic. It gave me opportunities that I never would have had the chance to experience otherwise. The purpose of this experiment was to use pillbugs to examine animal behaviors and habitat preferences and to determine whether this organism prefers moist or dry habitats, dark or light habitats, and acidic or caustic environments With knowledge of isopods and pillbugs, it was hypothesized that the pillbugs would spend more time near the damp filter paper because of their need for high humidity in order to breathe. The organism being observed reproduces on land instead of in water. As an intern, I worked on the activities for a curriculum unit on protecting animals when their habitat changes. Table 6 and Figure 6 show that the basic environment one with drops of KOH was actually preferred over a neutral environment and the acidic environment one with drops of HCl by the pillbugs.
Natural Insect Control Often these harmless creatures are considered pests. The pillbugs roll into a ball for safety. Our academic experts are ready and waiting to assist with any writing project you may have. The difference between the two can be found out by looking at the bugs side by side. Hopefully it was fun for the roly polys too! The second piece of circular filter paper was left dry.

They're in the isopod meaning same pod or foot family and have seven pairs of legs that are all similar in size and shape. For this activity, my job was to think of and test different materials that students would use to build a roly poly classroom habitat. Materials and Methods: Take a petri dish and place a moist filter paper on one side of the dish and a dry piece of filter paper on the opposite side. Otherwise, they can be found under things like bark or rocks.
During the day, pillbugs hide in moist places, such as under stone and bark. Also using a soft brush, five pill bugs were placed in the dry chamber while the remaining five were placed in the moist chamber and the chambers were closed. When the cyst is returned to its normal environment, it continues on with its development and eventually hatches. Results: Your results are a description of your roly-poly�s behavior during the experiment and its location damp or dry at the end of the experiment. As evidenced by Table 4 and Figure 4, the mean number of pillbugs in the damp chamber over ten minutes was approximately 5. Isopods have seven sets of legs while most insects have only three sets. We used about twenty bugs for our experiments, though you could use more or less depending on availability.
