Different Text Models for
Struggling Readers
Generally,students with reading difficulties find it difficult to read text passages.
Hence I wanted to find out if passages typed in phrase spaced formatting and
character spaced formatting would help them read better.
The participants consisted of eighty students from Class five to Class eight. The
participants consisted of the same number of struggling readers and good readers.
Suitable passages for each class were chosen with the guidance of teachers.
The control passage for each class was unchanged. Reading of the students was
assessed. Passages were re-typed using character spaced formatting. The reading
ability was assessed. Passages were again re-typed using phrase spaced formatting.
The number of words read in one minute was counted. The students were rated on a
scale of ten for their reading ability.
The data was collected and analyzed. The results showed that students of STD V who
scored 5% improved in this reading ability with phrase-space reading and scored 90%.
STD VI scored 100% while the STD VII and VIII students scored 95%. Nearly 100%
improvement was seen in the reading ability of students. Chi-square calculated for
STD VII was 193.78 with 4 degrees of freedom was significant.
The results showed that phrase-spaced formatting of passages helped the students
read better. Thus I conclude that phrase-spaced passages help students with reading
difficulties read better.
Herbal Dosage for Colony-Al
Damage
For centuries, our country has used traditional medicine and home remedies to treat various
ailments. In recent times it has also been observed that bacteria are becoming increasingly
resistant to certain antibiotics and thereby creating a need for new remedies.
The project aims to investigate the anti-bacterial properties of traditional herbal
remedies against Staphylococcus Arlettae and Escherichia Coli bacteria strains
collected respectively from blood and urine samples of patients. All experiments were
conducted at hospital and pathology laboratories using scientific procedures, under the
guidance of doctors.
Zanthoxylum Ovalifolium in
Anti-Lice Treatement
We came to know about a plant called zanthoxylum ovalifolium from our granny which
was used to remove lice from hair during her childhood days. As it is a natural way of
removing lice, we started our experiment out of curiosity. We prepared decoction out
of 1kg of fresh leaves by boiling it in 4 litres of water for about 2 hours and reducing it
to 2 litres. We also prepared decoction out of dried leaves of zanthoxylum ovalifolium
by boiling 1/2 kg of dried leaves in 1 litre of water for about 1 hour and reducing it to
1/2 litre. We also prepared oil by boiling 1/4th litre of water extract of the fresh leaves
with 1/4th litre of coconut oil.
We applied each of our preparations on different types of lice infested hair for
different time intervals of 30 minutes, 1 hour and 1½ hours. We observed that the
decoction made out of fresh leaves was very effective and suitable to all types of hair.
Through our experiments we came to the conclusion that this decoction when applied
and kept for 1 hour on hair removes lice from hair. For complete removal we need to
use it 4 times at the gap of 4-5 days. We also got the alcohol extract of dried leaves
and we are investigating the insecticidal property of the leaves
CONCLUSION:
This study gave a positive result to control the larvae of mosquito. In the present
study, the angiospermic and halophytic plant extract are used to kill the larvae. It is
found out that, this is a method to eradicate larval forms. From this, we conclude that
this method can be done further in an improved manner to kill the larvae effectively.

In today’s time of rising inflation, rotting of grains is a very serious problem and needs
to be taken care of. Despite of the numerous scientific ways present today, this
problem is not yet controlled completely and is creating devastating effects. Our
project aims to tackle this problem.
Our project deals with these problems and we are trying to control the beetles like
Tribolium castaneum (attacks wheat), Sitophilus oryzae (attacks both wheat and rice)
and Callosobruchus chinensis (attack pulses) by using castor oil, pine oil, fennel oil and
Hing in different concentrations.
Methodology: In this experiment we have taken 20 bottles each of 3 kinds mentioned
above. We are performing four experiments:
1) Contact toxicity of natural oils and hinge on Tribolium castaneum, Sitophilus oryzae
and Callosobruchus chinensis adults.
2) Toxicity of treated wheat on Triblium castaneum, Sitophilus oryzae and
Callosobruchus chinensis adults.
3) Evaluating the repellent effect of the applied oils on Tribolium castaneum, Sitophilus
oryzae and Callosobruchus chinensis adults.
4) The effect of natural oils on fecundity of Tribolium castaneum, Sitophilus oryzae
and Callosobruchus chinensis adults.
Result: It was concluded from the observation that all the three oils are effective,
castor oil being the most effective. Thus, commercial industries should use these oils
for making various formulations to control stored grains pests.
