With the Chinese New Year celebration going on, it means plenty of mandarin oranges- the most common citrus fruit to make eco-enzyme.
So, what else do you need other than oranges?
3 basic ingredients:
- Sugar: food source for fermentation
- Orange peels
It’s that simple! Are you ready for a simple tutorial?
The eco-enzyme is ready about 3 months later or when all the peels sink.
So, what can you do with the eco-enzyme? Well, the common use is as a cleaning agent. Check out the tips below!
We have some cardboard boxes collected from neighbours for craft work, and since it’s the festive season, I decided to do up a Christmas tree, inspired from this website.
I didn’t do any measurement or use any template. Simply sketched directly on the board and cut it.
I cut another template and cut it vertically half. Then, we painted the pieces!
The last part, is to put them together and decorate it. In the spirit of upcycling, we used bottle caps and breadbag tags for decoration.
Such a easy-peasy DIY project to do with kids this holiday!
Experiments on the topic of experiments can be tricky because there are just a lot of variables that can affect the brightness of bulbs.
I’ve made 3 videos for this. Results are not shown in the earlier part of the video, so students will still have to carry out the experiment to record the results.
Effect of number of bulbs, arranged in series, on brightness of the bulbs.
Effect of number of batteries, arranged in series, on brightness of the bulbs.
Effect of number of bulbs, arranged in parallel, on brightness of the bulbs.
Tutorial for a simple DIY game- basically player will earn points as the marble roll down the board.
Made the simplest slime with the P3s using 3 ingredients only.
Watch the tutorial below:
A simple demo to demonstrate the distribution of stomata on a leaf.
Demonstration set of haze/ air pollution
Creating haze in a beaker.
1. Measure and prepare aluminium foil to cover beaker.
2. Light up wooden splint and drop it into a beaker.
3. Cover with aluminium foil.
4. Place ice on it.
Use white paper towel to wipe the inner surface. Students will be able to observe very fine soot
Possible changes, use leaves and soil as a close set-up to forest. But didn’t work too well when I tried. Leaves must be really dry to burn/catch fire.
