Experimental design project about exploring diversity of matter

Experimental design project about exploring diversity of matter 

Do we all all know that everything around us is made of matter?
Do we ever realize how many types of matter contribute to our lives?

Those questions had been discussed when I taught grade 7 on this first semester of 2017/2018 academic year.  Students learn about exploring the diversity of matter by learning about the concept and doing experiment project. The following are the evidence of how grade 7 students learn about the concept of scientific endeavour and diversity of matter.

Picture 1. Experiment About Filtration 
and Erosion Model

The first experiment is about filtration and erosion model. The students were conducting an experiment about which type of soil could purify the water and help for the erosion. Then they made the result in the form of lab report. After that, they reflected this experiment and  made a video campaign on you tube link to inform the importance of planting the trees for helping eroion and purifying water. This is the link of the video that they made:

Picture 2. Experiment About pH Natural Indicator

The Second picture is an experiment about pH Natural Indicator. They discussed and compared which type of vegetables work effectively to be used as pH natural indicator. They used red cabbage and turmeric. Then they got the result and made the complete laboratory report. The result showed that red cabbage is more effective to be used as pH natural pH indicator because the reaction is faster than using the turmeric. After that, they made a video about the importance of their experiment for the society. This is the link of the video : https://www.youtube.com/watch?v=vrzkeCDMWMU

Picture 3. Experiment About pH Natural Indicator 
using different procedure

Picture 4. Experiment about testing the borax
 by using different type of matters with Turmeric

The third picture is another experiment about pH Natural Indicator. They also still compared about which type of vegetables work effectively to be used as pH natural indicator. However they made different procedure from another group. Then they got the result and made the complete laboratory report. After that, they made a video about the
importance of their experiment for the society. This is the link of the video : https://www.youtube.com/watch?v=OglygoxFnnk


The fourth picture is about an experiment for testing the borax content on foods by using different types of matter by using  turmeric. They used cotton bud, tooth pick and paper. The result goes to paper. Then they made a final report. After that, they made a video to inform people through social media. This is the link of the video that they made: https://www.youtube.com/watch?v=G8GBTiU7fn0




The fifth picture is an experiment about making a mosquito catcher by using different type of matter and colour. They compared on which kind of colour effectively trap the number of mosquito. The result goes to dark colour. Then they made a final laboratory report. Finally they made a video to inform the people through social media. This is the link of the video ; https://www.youtube.com/watch?v=E7olOyxQXYA

This science project is also part of the service learning. It shows their knowledge and caring to the community and the environment arround them. Hopefully this project can bring benefits to everyone that see the result of their project.  
A famous quote from Peter Senge that " sharing knowledge is not about giving people something from them. That is only valid for information sharing. Sharing knowledge occurs when people are genuinely interested in helping one another develop new capacities for action; it is about creating learning process."
