Sq iirmy Science Final Design Report
Metro Middle School September 16, 2015
EXECUTIVE
SUMMARY
This project is mostly about kid/teachers who create a ecosystem for home or school. We had to get a bottle and get the right things for the mealworms to survive in. So we only had a limited amount of food and dirt. Plus a limited amount of holes, and the holes were only allowed to be an inch long. We would look at them every day to see and write how they were doing. Then at the end wrote about how they grew.
Our design was to have 3 mealworms, a flap, and a couple of 1 inch holes. We added almost 200mL dirt. We used 100 mL of oatmeal. Then we added a few sliced potatoes in the bottle. Our mealworms ended out eating what we gave them. They turned out healthy and that was the goal we had initially made.
OUR DESIGN SKETCH
)O
ld)
DETAILED
DESCRIPTION
For the structure of our mealworm habitat, we chose to use a 2 liter bottle on its side. Using a scissor, we created a flap on top of the side of the bottle to form an opening for customers to replenish food and/or soil. Our source of food for the habitat was 100 mL of oatmeal and two potato pieces. We used the potatoes because we learned that mealworms need water and cannot directly get it from a container, and the potatoes are very moist. We also added l O mL of water, to add even more moisture. We had three mealworms which weighed 0.6 grams in the beginning, and ended weighing 0.9 grams.
DEFENSE OF DESIGN
Our design solution met the design requirements in many ways. We did a lot of research about mealworms to make our design perfect. Although we did have some flaws (paragraph three), our habitat held our mealworms pretty well. First, we used an inclosed 2 liter bottle, and filled the bottom with a lot of soil and oatmeal. We did this because mealworms like to live in places surrounding their food, and burrow a lot in the soil. We also added potatoes for variety, since mealworms eat a variety of foods. The potatoes were also moist, and mealworms get their source of water from their foods. lO milliliters of water was then added to keep the soil moist, and we then placed the bottle under the dark table, because mealworms like to live in dark, moist places. Overall this was our basic design, and the reasons behind it. Our mealworm habitat did fine overall. Although we had a mealworm missing, the other two seemed pretty healthy. We had enough food inside of our mealworm habitat for the mealworms to live in it for another 4-5 days. In the beginning, all three mealworms weighed 0.6. After five days, they had weighed 0.9 grams. We got third place when our mealworms were being weighed. We found that the missing mealworm could've climbed out of an air hole that was a little too close to the ground. This is one of the many things our group wanted to change about our design. Our group has many suggestions for future testers. The number one recommendation is that you should spend your money wisely. The mealworms didn't eat all of the oatmeal and

u
potatoes we gave them; they didn't even eat half of it! Also, if you use less money, there's a greater chance that you'll make more profit from it, as you will have more habitats for less money. Another piece of advice is that the mealworms live in a dark and damp place. We put our mealworms under a table and the soil was very moist. Overall, I think the biggest suggestion is that you reduce the amount of money you spend. APPENDIX
Day 1
Day2
Day3
Day4
Day 5
Mealworm 1 was burrowing, Mealworm2 was exploring and moving a lot in it's new habitat. Mealworm was just sitting.
We can only see two mealworms. They are mostly burrowing in the dirt. Mealworm 1 can be vaguely seen. Mealworm 2 is burrowing. Mealworm 3 is not to be found.
Mealworm 1 is mostly eating and burrowing. Mealworm 2 is crawling around and exploring. Mealworm 3 is not to be found.
Mealworm 1 is eating, mostly around potatoes and oats. Mealworm 2 is burrowing and exploring around. Mealworm 3 is not to be found.
Mealworm 2 is eating. It is mostly stationary . Mealworm 1 is moving around a lot and burrowing.
Food Availability: Is all/enough food available?
There is enough food for them, but we will be adding more food. They were eating the potatoes.
There is quite a lot of food. Mealworm 1 looks fatter, Mealworm2 looks about the same.
There is still a lot of food, and mealworms have gained weight.
There is still a lot of food. Both mealworms look considerably fatter.
Still a lot of food. Both look fatter and have gained weight.
Color change?
Orangish brown.
Medium brown, but a little more to the darker
They are a little lighter than yesterday,
There are even lighter than yesterday.
They are very light, with thin brown nngs.
What are we observing for? Movement:
How are they moving/are they?
