Last week, a staff member took my exhibits on a business trip without my permission. And, as expected, those exhibits were broken, defaced, or gone. Their behavior is at the level of Japanese elementary school students. I wish they would b…

A JICA volunteer visited CEMASTEA. She was the ninth visitor. I introduced her to the sundial I made. She is a junior volunteer and is a mathematics teacher at a high school. I hope we can cooperate with each other.

Today, I was again moved by a new discovery and created an exhibit. When an object is thrown up, only gravity acts on the object from the moment it is thrown until it finishes falling, so it becomes weightless, just like zero gravity. Grav…

Today is my 4th time working from home due to a demonstration. I was told not to open the windows because of the flying rocks.

It took me a while to understand the principle, but I've finally completed the 独楽-type sundial. Since Nairobi is about 1 degree latitude, this board should be set up almost vertically, with the stick pointing directly nouth and south. Ri…

Since there is no "下敷き" in Kenya, I found a substitute. I was able to display "static electricity", which is familiar in Japan.

I finally took Kenya Railways' 6:35AM train to Nairobi at Dagoretti Station. I had no idea so many passengers were using the train (photo above). The photo below shows a man seeing his child off to school. I think we should use railroads m…

A JICA volunteer from Tanzania visited CEMASTEA. She is an elementary school teacher in Kyoto Prefecture. She was in the same group as me during the training in Nihonmatsu City. I'm thankful for this. She plan to travel toTanzania → Rwanda…

I was ordered to work from home by the JICA office again. We held an online meeting with the United Nations Office for Outer Space Affairs. The United Nations is trying to get Africans more interested in space. It was a very valuable oppor…

This morning at 7:35, I was suddenly ordered to work from home by the JICA office. This is my second time working from home. At that moment, I felt happy. Do I hate volunteering?

I went to Dagoretti station to take a photo of the train. But the train wasn't there on Sunday.

I observed a biology class at Nkaimurunya High School. The students were all serious and the teacher was excellent, but it was unfortunate that there were 65 students in one class.

This(↓) is a world famous puzzle called the Tower of Hanoi.

When I rolled a rubber band down a hill, it rolled well. Since I was surprised, I thought my students would be surprised too, so I came up with this exhibit. This is Gyro effect. It's the same as a bicycle (↓). I came up with the idea for …

An insect that looked just like a Japanese beetle came into the room (↓). I wonder how it evolved.

Following last week, this week was also a quiet week with no school visits. I made a new exhibit. The number of exhibits I was involved in has now reached 72.

I was really interested in the SGR that crosses the Nairobi National Park, so I took the SGR train from Nairobi to Ngong. The 50-minute journey cost only 130Ksh. The tea I had at the station (200Ksh) was more expensive. The station staff a…

I bought chemical seasoning (top photo) for the first time at the Japanese food store “Jinya”. They're not available at regular supermarkets. My eating habits will change drastically. In Kenya, taxis refuel frequently. Today's taxi only re…

I supported the United Nations Space Education Pilot Class at Oloolua Primary School. It was organized by the United Nations Space Division and was a very valuable opportunity. It was decided today that the day after tomorrow will be a nat…

I finally understood the meaning of the mysterious exhibit(↓). To continue to burn, new air must come in.

I had Tilapia(↓) recommended by a waiter at a restaurant in Eldoret. Tilapia is a lake fish. This is the fish of Kenya (People living near Lake Victoria also eat Nile perch). It was not tasty as expected. This cost 1,200Ksh (≒1,320Yen). It…
