Here is a blog by a 5th grader who attended his talk :
On Friday we had a talk about soil, there was Vasu Uncle who came and we did a few activities and we learned a lot.
Then we did a activity on collecting different soils like soil from direct sun, soil from under a big tree, soil from under a small plant. We discussed about the different soils and what makes them different.
Then we again did another experiment. Uncle called three volunteers and told each of them to take three different soils and then put drops of water until it was a good texture good enough to mould. Then Uncle told them to make different shapes and see if they cracked or broke.
At last the last experiment Uncle had two recycled pots. One of the had no plants and the other one had a plant and many weeds. The recycled pots were made from halves of a water can but they kept it tilted so the mouth of the water can was something like a drain. So then Uncle poured water on the one with no plants. We saw that the water did not get soaked but since the can was tilted the water came out through the mouth but when uncle poured water on the one with the plant and the weeds the water got soaked within seconds.
WHAT I LEART
I learnt many new things about how soil is very important and what is good for soil and plants.
