Weekly Reflection of Year 7 Learning #6

Today, I want to talk about the summative assessment that I’m currently doing at my school. In Cikal, this summative assessment is like an exam, but in the form of project. With this final project, the teachers will know our understanding about that topic.

Last week my teachers in all subjects already informed the summative assessment project that we will be working on for the next 2 weeks. So looking at the calendar, we should finish this project before the camp that I have told you in my last post.

In Individual and Societies lesson, our project is related to colonialism and Indonesia natural resources. So in this project, we pretend to be Netherlands that want to colonialize Indonesia in 14th century. Each of Year 7 students got our own area with it’s natural resources. For example, I got South Coast of Java with Jati wood as it’s natural resources. Our task in this project is convincing an investor from Netherlands to do an exploration in our own area. The way we convince them is by making a letter containing some reasons why the exploration would be benefitial for Netherlands and some data about  the natural resources in that area.

Moving on to the other lesson, in Bahasa Indonesia, we need to make Laskar Pelangi book review. Then, we need to compare the book with the movie.

About the book, Bu Nida told us to read the book since 3 weeks ago. Some of us already finished the book since last week, but some of us didn’t finish it yet. Although we watched the movie last week and we supposed to finished the book before we watched the movie.

In this lesson, I still making the review about the book, and I hope this weekend I can start to make the comparison between the book and the movie.


Science was the most interesting one for me. For the summative, we did three experiment about acid and base, then we need to make three reports about it.

We did the experiment two days ago, and it was so fun! The first experiment was making natural indicators using carrot and red cabbage. Then we compared both of them and observed which one is better.

So the indicators were poured to the acid (citric acid) and base (sodium carbonate) 10 drops each. From there we know which one is better just by looking at it. The better one is the red cabbage indicator. The reason is because we can see the difference between the acid and base after we poured the indicator in it. The acid solution turned into pinkish color, while the base solution turned into tosca color.


The second experiment was testing whether some household item is an acid or base. We used the red cabbage natural indicator for this experiment, and there were 11 household items that Miss Via bought. Those 11 household items contains drinks and a few kind of cleaners.


To test whether it is acid or base, we poured a little amount of that household items into a test tube. Then we put 10 drops of the red cabbage indicators to each test tubes. Finally, we have to observe the color changing of that solution.

While in the third experiment, Miss Via told us to mix acid and base together and observe the result. The observation that we made consist of: whether the pH changes and the pyshical changes that we can directly see with our own eyes.

We didn’t mix the acid and the base immediately, but we mix 40 ml of acid with 10 drops of red cabbage indicator first. Then we add 5 ml of base and observe it.

We poured the 5 ml of base 4 times. But in the middle of each pouring, we dipped a pH paper strip in the solution and we need to find out how much pH is in that solution. From my result, if we have acid and mix it with base little by little, then the pH level will increase slowly.


About all of the assessment, although the due date is next week, I really want to finish all of the projects this weekend. That way, I can do consultation to the teachers earlier and I can have time to do a lot of other things.
