Results


Bean Plant Experiment #1

These results are based on the first attempt at this project... the following attempts all failed

Control Plant

Artificial Sugar Plant

"Real Sugar" Plant

grew and sprouted normally

grew and sprouted "upside down" (roots first)

soil was not rich- it had a white, powdery residue on the surface

No results available (did not sprout due to some interferences)

 

Bean Plant Experiment #2: Bean Plants in Petri Dishes

Measurements (approx.) Before Commencing Experiment

Control Bean

"Real" Sugar Bean

Artificial Sugar Bean

12.0 cm

6.5 cm

8.75 cm

 

Bean Plant Experiment #2: Bean Plants in Petri Dishes

Approximate Measurements After Commencing Experiment

Date

Control Bean

"Real" Sugar Bean

Artificial Sugar Bean

April 3

13.0 cm

6.5 cm

8.75 cm

April 4

14.5 cm

6.5 cm

8.5 cm

 

Bean Plant Experiment #2: Bean Plants in Soil

Date

Control Bean

"Real" Sugar Bean

Artificial Sugar Bean

April 3

NO APPARENT CHANGES

April 4

Slightly shrivelled

Both very shrivelled

April 5

One plant has grown 1 cm

Both very shrivelled

 

Daphnia Experiment

These results are based on all attempts to this project

Control Daphnia

Artificial Sugar Daphnia

"Real" Sugar Daphnia

Original no. Of heartbeats before testing= 132 b/m

No. of heartbeats after placed in sugarless, distilled water for 5 min.= 108 b/m

Decreased 24b/m

Original no. Of heartbeats before testing= 104 b/m

No. of heartbeats after placed in artificial sugar solution for 5 min.= 148 b/m

Increased 44b/m

Original no. Of heartbeats before testing= 68 b/m

No. of heartbeats after placed in "real" sugar solution for 5 min.= 144 b/m

Increased 76b/m

b/m= beats per minute

 

Daphnia Experiment

Postmortem Examination

Control Daphnia

Artificial Sugar Daphnia

"Real" Sugar Daphnia

The bodies were in fragments

Decomposition state

The bodies "internal organs" seemed to be intact

The outside protective membrane appeared "frizzled" looking

The bodies were in a fairly good state of "preservation"

 

Radish Seed Experiment

Control Seeds

Artificial Sugar Seeds

"Real" Sugar Seeds

Sprouted on Day 3 of experiment

Grew quickly

Fast growth rate

Quite long in length

1/3 radish seeds sprouted

Slow growth rate

Last set of radishes to sprout

1/3 radish seeds sprouted

Slow growth rate

Second set of radishes to sprout
