Class Trip to Beth Shalom Organic Farm

Friends at the bus :))

On 12th September, Grade 6 classes has class trips to Beth Shalom Organic Farm. My class, 6D, was joined together with 6F for the class trip. Beth Shalom Farm was not that far from our school, maybe around 20-30 minutes by bus. Since the road going there is small, we've got to stop with the bus and use smaller cars halfway there. In Beth Shalom, we learned about monocotyledon and dicotyledon plants, different types of artificial vegetative reproduction, such as grafting and air layering, and we also got to have our own plant to be brought back to school for our next AA score. 

Friends at the bus :)

We were explained about mono/dicotyledons

 So, when we arrived there, we were introduced about Beth Shalom organic farm. Then, we were split into 3 groups. I was in group 3 (If I'm not mistaken :D). Each group has a guide. After that, we were brought around the farm by our guide. He explains about the difference between monocotyledons and dicotyledons. Starting from the root to the petals. We were also assigned to pick one small plant from the garden and explain if it was dicotyledon/monocotyledons. Then, our guide showed us about two different methods of artificial vegetative reproduction  ̶  air layering and grafting. Then, we head back to the "meeting point" (that's what I call it :D). FYI, what I call the "meeting point" is where all the 3 groups are gathered together and explained things by the guide. At the meeting point, we had to plant our own plant to be brought back to school. First, we take the stem that have been cut. Then, we take the black plastic and put soil in it. Then, we add some white substances to the edge of the stem to make it grow faster. Then, we tie the plastic with rafia string. Unfortunately, my plant did not grow :((

We were explained about the tools needed for artificial vegetative reproduction

We were showed examples of mono/dicotyledons around the farm =D7

The picture on the left was when we were showed how to do air layering :-bd

The picture on the right was when we were showed how to do grafting. :-bd

Science AA1-Talk Show

Around a month ago, after the Lebaran Holiday 2012, we had our science talk show drama for our scores in AA1. If you're wondering whats an AA1, it stands for ALTERNATIVE ASSESMENT which means somekind of test but in a different way. In this term's AA, we had talk shows. We were grouped into 4 person each group. In my group, there was Niki, Arvin, Andrew and me. In our talk show, we should choose either smoking, alcohol or drug abuse to talk about. Each of the person will role play such as the doctor, the host, the drunker/smoker/alcohol drinker and also act as the person who got affected such as their "parents" or "brothers and sisters". Our group choose alcohol. So, the story begins when Arvin was offered drinking alcohol by his "friends". Then, he got drunk and blacked out and was brought to the hospital. Then, a year later, he stopped drinking alcohol and got to a talk show with the doctor. The drunker act and alcohol bottle is fake ones. It was cool because I got to know how it feels like in a talk show.

Science Experiment-Balloon Yeast

In science, somewhere a month ago, we had our science experiments in yeast since our science topic that week was about cells. We wanted to find out if yeast could grow without energy. So, here is what we need:

50ml Conical Flask

two 50ml conical flasks
hot water
a beaker
a Bunsen burner
a thermometer
a teaspoon of yeast and sugar
two balloons
measuring tape
a stopwatch.

Here are the steps.

First, pour 60ml to the beaker and heat it with the Bunsen burner. Using the thermometer, observe the temperature of the water. When it reaches 38 degree Celsius, stop heating.
Second, pour 30ml of heated water into each conical flask. Name one flask FLASK A and the other one FLASK B.
Then, add a teaspoon of yeast to both of the flasks.
After that, add a teaspoon of sugar in FLASK B ONLY.
Lastly, cover up the mouth of each flasks with the balloon immediately to prevent losing the water heat.

Then, we observed for 5, 10 and 15 minutes.
We measured the distance around the widest part of the two balloons.

It should look like the picture on the left for FLASK B.
Why only FLASK B?

Budding in yeast cells

Here is the explanation.

To grow and divide, yeast cells need energy. Sugar is the source of energy. Then, it will produce carbon dioxide and alcohol, which makes the balloon inflate.

Unfortunately, in my group's experiment, our balloon did not inflate as it was supposed to. But at least, we've tried :D

INTRODUCTION

Hello!  I'm Glenn Alexander, and now I'm grade 6. If you haven't know me, i'm introducing myself. I come from BiNus Internaational School Serpong. I am 11 years old now. I live in Indonesia. I made this new blog only for grade 6 science projects. My previous blog was www.glennalexander260.blogspot.com which was for grade 5. I would post pictures and texts about what we have done in our science class, AA (Alternative Assessment). For more info about me, just email at glennalexander260@gmail.com or visit www.glennalexander260.blogspot.com.
