Bess Beetle Maze Mania

Najee S, Victor L

We chose to test how fast a Bess Beetle can navigate through mazes.We  made three different Lego mazes. 


Bess Beetle Rough vs Smooth

Jenna U, Nadia O, Anna G

Question: How does the rough or smooth that the Bess Beetle is on affect the Bess Beetles speed of turning over?

In our investigation we tested how long it takes three Bess Beetles to turn over faster or slower or rough or smooth surface. The purpose of the investigation was to find out whether or not the Bess Beetles turn over faster on smooth or rough surface.  Our study supported the hypotheses because the Bess Beetles turned over faster on the rough surface.

Facts we know: Bess Beetles are decomposers. Bess Beetles like to chew wood, but unlike termites, the fungus gives them nourishment, not the decaying wood. Bess Beetles are classified under the Coleoptera order.  Adult Beetles are about  1.5 inches.


Bess Beetles On the Roll

Olivia K, Vada S, Patricia V, Lindsey X

We decided to experiment on how temperatures affect the speed of a Bess Beetle. First we created a tan paper track. We used a heating pad for hot weather, went outside for cold weather, and stayed in for room temperature. We used thermometer to record all the different temperatures. We came to the conclusion that the colder temperature made the beetles go faster!


Cockroach Rampage

Chyna Y, Taylor O

We tried to find what moist envronrment the Madagascar Hissing Cockroach would spend the most time in. We think they will spend the most time in the moist woodchips.


Competitive Cockroaches

Johanna U, Kayleigh D, Mikayla H

We chose to see if the length of a cockroach affects it's running speed.We designed an investigation that would test their speed by using a track to time them.


Cricket Investigation

Mitchell O

In our investigation we wondered if the temperature will affect the activity level of crickets. We put a heating pad under our cage at high temperature. Then, we counted the number of jumps for 1 minute for five times with five crickets.

We chose this investigation because we wanted to know if the temperature of a cricket's living environment would affect its activity level. Our data supports  Hn because the activity level didn't change.

Our uncertainties are the temperature might not be consistent or the new terrain might have affected them by making more or less active. We also only tested the control one time; we should have tested it 5 times and found an average. Our data supports that their activity level doesn't rise in warmer temperatures.


Darkling Beetle Investigation

Emma A, Nhu N

How does the dampness of the substrate affect the digging behavior of the darkling beetles?

We decided to do this investigation because we thought it would be interesting to see if the darkling beetles are attracted to damp substrate or if they are attracted to dry substrate?  Our investigation supported our hypothesis that the beetles prefer the dry substrate.  The Darkling Beetle eats leaves, sticks, and grass. Their predators are lizards, rodents, and birds.Their habitat is under logs, and rocks. It is hard to tell if a Darkling Beetle is male or female. The time to turn to a beetle from a mealworm is about 3-5 months.


Hiding Habits of Madagascar Hissing Cockroaches

Sinai L, Jacquelyn V, Megan K

We attached a harness to our cockroach and attached a petri dish to the harness. When it was attached we had gram weights on the petri dish while the cockroach was on the track.

We wanted to find out if the weight of the cockroach affects the weight it can pull. We found the weight of the cockroach does not affect the weight it can pull. This supports our null hypothesis (Hn).

We thought the age of the cockroach and the surface of the track might affect the weight it can pull. We learned that cockroaches can pull more than 20 grams in weight.

The result of our investigation supports our null hypothesis (Hn) because all our cockroaches were different weights and we found it didn't affect how many grams they pulled.


Hissing Cockroaches

Angel D, Lizzie S, Paris S

We wanted to find out how long it would take cockroaches to get through three different mazes. All three cockroaches made it through each maze in less than 5 minutes.


Hissing Cockroach's Reaction to Music

Montarius D, Bethany L, Thomas M, Michelle M

We made a box out of paper, and we used three cockroaches to find out how music affected their behavior. We played hip hop, rap, country music, and no music. We found that the cockroaches had different reactions to the different types of music. We learned that cockroaches like some kinds of music.


Hot and Cold Cockroaches

We wanted to find out how temperature affected hissing cockroaches activity level. We wanted to see if they would move more in a cold climate or a hot one.


How do different substrates affect a darkling beetle's time above and below ground?

Ulahn X, Zach Z

We did an experiment with different substrates and darkling beetles. All of us wondered how the different substrates would affect the darkling beetles' time above and below ground. We found that the darkling beetle was under the surface in bran the longest. The darkling beetle burrowed in dirt too, but the darkling beetle didn't stay below ground the longest. The darkling beetle did not burrow in sand or gravel. We didn't know how moist each substrate should be, so we decided to keep everything dry. In the future we think we could change the dampness and/or temperature in an experiment.


How Does Temperature Affect Millipedes Curling up?

Jarmare S, Namo A, Tyler O

We wanted to see if millipedes would curl up more in different environmental temperatures. We tested them in cool, room temperature, and hot environments. The millipedes curled up more in the cool environment.


Hungry Bess Beetles

Chad K, Mitchell L

Our investigation tested whether Bess Beetles would eat dry, damp, or wet wood. We observed three out of four Bess Beetles eating the dry wood.


Investigation Cockroach

Lizzie S, Taeveon R, Erin M

We attached a harness to our cockroach and attached a petri dish to the harness. When it was attached we had gram weights on the petri dish while the cockroach was on the track.

We wanted to find out if the weight of the cockroach affects the weight it can pull. We found the weight of the cockroach does not affect the weight it can pull. This supports our null hypothesis (Hn).

We thought the age of the cockroach and the surface of the track might affect the weight it can pull. We learned that cockroaches can pull more than 20 grams in weight.

The result of our investigation supports our null hypothesis (Hn) because all our cockroaches were different weights and we found it didn't affect how many grams they pulled.


Lights,....Camera,....Darkness?!?! The Bess Beetles

Ryan L, Ryan W

We tested the bess beetles' light amount preferences to see if they preferred light or dark environments. We had three hypotheses, 1) that they would prefer light over dark; 2) that they will prefer dark over light, and 3) our null hypothesis, that they wouldn't have any specific light preferences. Our results were unexpected because they preferred light over dark, although our practices before the actual experiment showed them preferring the dark. We were uncertain about this sudden change, and thought they might have been trying to escape.


Massive Cockroach Investigation

Isaac C

We tested 3 cockroaches and played 3 different levels of music (32 bars\16 bars\ 8 bars) on an iPod to see if they would bury themselves. We played the song Beat It by Michael Jackson. In our investigation we tested these cockroaches to see if the vibration from the sound would make them want to bury themselves in the wood chips. The results that we observed were that the 3 different levels of volume (32 bars\16 bars\ 8 bars) did not seem to change their burying behavior. Because of the controlled environment we had for our investigation we cannot determine that they do not feel any vibrations. We wonder if cockroaches adapt to the environment that they are in. If were going to do this investigation again, we would add more wood chips so that they could burying themselves further, use louder music, and do the investigation for a longer period of time.


Milliclimbers

Grant J, Carter C

We attached a harness to our cockroach and attached a petri dish to the harness. When it was attached we had gram weights on the petri dish while the cockroach was on the track.

We wanted to find out if the weight of the cockroach affects the weight it can pull. We found the weight of the cockroach does not affect the weight it can pull. This supports our null hypothesis (Hn).

We thought the age of the cockroach and the surface of the track might affect the weight it can pull. We learned that cockroaches can pull more than 20 grams in weight.

The result of our investigation supports our null hypothesis (Hn) because all our cockroaches were different weights and we found it didn't affect how many grams they pulled.


My Darkling Beetle Investigation: Moisture of the Substrate

Matt Y

I put darkling beetles in different moistures to see if the moisture of the substrate affected how deep they dig. Mr results show that they dig the most in dry substrates. The second most was wet substrates.


Operation Bess Beetle

Alissa F, Ayesha Q, Loreal F

We tested to see if the bess beetle can flip over on the rough or smooth surfaces. It turned out that the bess beetle can cling on to the woodchips to help them get up. We tested our experiment a couple times.


Speedy Millipedes

Phan L, Karolina O, Bruce L

We put out a coarse to determine if the length of millipedes affects their speed. We built the coarse out of connected blocks and timed the millipedes. The 7 cm millipede took 58 seconds on average. The 7 and a half cm millipede took 73 seconds on average and the 14 cm millipede took an average of 59 seconds. So the null hypothesis was the most correct: the length of the millipede doesn't affect the speed.


Speedy Millipedes

Sarah T, Jahziel Y, De'Vonna N

Our group tested how long it took for three different length millipedes to get through to the end of a 13 in. Lego wall. Our purpose was to see if there was any relationship between length and speed of a millipede. In our results the shortest millipede and the longest millipede had the same average, though the shortest one faster trials, with one outlying trial.The middle length millipede was the slowest in its times and average. We were not sure the middle length millipede was at its best the day we tested it. We saw a skin, so it may have shed. If we were to try an experiment relating to this experiment we would like to see if a shorter millipede would go faster in a shorter course or if the longer one would have more endurance.


Temperature Beetles

Connor M

In this investigation, we put Bess Beetles on heating pads and ice packs and measured how far they walked. We studied the Bess Beetles to see if their activity level changed. Our results support our Hhypothesis. The Bess Beetles were more active after being on the heating pad than the ice packs.  We learned that the farther they moved,  the more active they were. If we were going to do this investigation again, we would have more controls by making sure the temperature was more hot and more cold. We would also put the Bess Beetles in different bins so we could tell which ones we already tested.


The Speed Demons: The Hissing Cockroaches

Nicholas C, Alex S, Austin T

We tested the cockroaches to see how fast they could complete the maze in groups and by themselves. There were three trials. We found that the cockroaches work better in groups.


The Strong, the Weak, and the Roaches

Rich Y

We studied the Roaches to see how much the Roaches could pull. We tied a string to the Roach and put some paperclips and magnifying glasses on the sled as weights. After that we weighed the Roach and the sled. We found out that the Roach can pull up to around 6-7 times its body weight.


Usain Bolt Roaches

Ryan D, Sikai Y, Brenton B

We did a study on how mass affects speed of the Hissing Cockroach. Our investigation was designed to find out the speed of Madagascar Hissing Cockroaches.
