Are You Deceived by SDGs？

This study shows what we should do to solve international problems. First,we conducted a questionnaire for our school students.As a result, a lot of people are interested in the problems of SDGs,but most of them do not find a way to solve these problems.Based on this result,we thought that people might need to get some support from the government.So we went to the Kyoto prefectural office during school trip because of researching the activity by these institutions and obtaining some beneficial information.They told us that we also are in trouble because they find it difficult to gather the opinions of citizens. 

The Insulation Material Using Honeycomb Structure

This study explores a new insulation structure aimed at reducing carbon dioxide emissions. We focused on a honeycomb structure.From two experiments , we found that processing insulation into a honeycomb structure does not reduce its insulating performance compared to common insulation. We think that this new structure can help reduce the amount of material required .Additionally, we hope to promote the use of insulation made from natural materials such as STEICO ,in Japan through public presentations.

Indoor Greening Based on an Example in Classroom

This research explores how to green indoors by taking our classroom as a model. First,we looked up six kinds of house plants which are proper to greening. Then, a survey measured the illuminance at some points in the classroom to determine where to put these plants. The results showed that plants can be put at almost all points. Also, it found that we can examine greening rates in sight to improve mental health. This research may help increase green.

How to Make Effective Use of Thinned Wood in School Forests

Our school has had a school forest for 60 years, and there are a lot of logs.We decided to make key rings made of the logs to use them effectively.To make them,firstly,we counted the number of logs in our school forest and dried them.Secondly,we carried the logs from the forest to our school.After that, we made key rings.Key rings we made are very hard and practical.And,it may be useful for us.We will hand out key rings to each class.Moreover, We are going to try to find other ways to use woods effectively.

The Paper Made From Seaweed

This study explores how to make paper from seaweeds for the purpose of preserving the environment. As you know,society aims paperlessly to improve the environment. We think we can improve the environment in another way, making paper from seaweeds as the same meaning paperless.We tried to make paper from seaweeds by CaCl₂ , calcium lactate and alginate.We can gain alginate from seaweeds such as kelp.We tried anyway for example changing concentrations,changing the phenominal that is used to make paper how to dry paper and so on.Finally,we couldn't make paper we can use as a paper however we could find better way in our research.We wish we or other people research more and we ca make paper from seaweeds for enviroment.

Using Ethanol Helps Plants Better Tolerate Heat Stress

The study explores the sorts of plants which improve their tolerance to dryness by getting ethanol. Spreading this diversity, I think we may help refugees. We research the shift of tolerance of spinach by ethanol because spinach doesn’t have more tolerance to dryness. First, we grow about ten pots of spinach.Second,some spinach are given thin ethanol, the others are given the same amount of water. After we left them for 7 days, we observed their condition and their stomata. As a result, we could observe improved tolerance to dryness, but the stomata of both spinach closed. Therefore, ethanol doesn't always make spinach improve good tolerance to dryness. We hope to observe the stomata of spinach in an arranged condition.

The Impact of New Standard Bat

We investigated the effects of the new standard bat used in high school baseball from data obtained at Koshien Stadium and from experiments on the coefficient of repulsion of the old and new standard bats. The results of the data showed a decrease in the long-ball rate, suggesting that the new standard bat had an effect. The experiment has not yet been successful, so we will continue to make it successful.

The Best Way of Cooking Brown Rice from its Dispositions

This study explores the most efficient way of cooking brown rice by focusing on the amount of water and how long it takes to absorb water. Generally speaking brown rice needs lots of time to finish perimeter. To research about it, we conducted 2 experiments. According to previous studies,it takes at least 8 hours to put brown rice in water to eat brown rice deliciously. However, the data indicates that before the arrival of 8 hours, The percentage of water absorption has finished, but it is not good. The finding suggests there is an important element that cannot be expressed numerically.

Effects of Tea Dregs on Plants

We conducted an experiment to explore whether used tea leaves could promote plant growth. In our study, we grew plants in two types of soil—one with dried tea dregs mixed in, and one without. The results showed that the plants in the tea dregs soil had larger leaves on average. We believe this is because tea dregs still contain useful nutrients like nitrogen and potassium, which are essential for healthy plant growth. Although we didn't measure root size precisely, we observed that the radish roots looked stronger and grew better. This suggests tea dregs may help both leaves and roots grow.

Reducing Salt Intake by Using Soup Stock

This study aimed to reduce salt intake by using soup stock in potato chips. We created "soup stock salt" and tested chips with different amounts: 0.3g, 0.4g, and 0.5g. A total of 23 people participated in the tasting. About 70% preferred the 0.3g version, saying it was delicious. These results suggest that soup stock can reduce salt while maintaining flavor, offering a practical and tasty way to promote healthier eating habits.
