Plants project in 2nd grade

Kids from 2nd grade have been 2 weeks working in a project about plants. They already know a lot of things about them so they created their own plant and wrote all the different parts and explained what they need to grow up. Also, they drew it in a big poster and did an oral presentation in front of the rest of the pupils.











Density experiment

Kids from 3rd grade have learnt what "density" is. In Science class, kids helped me to make an experiment to demonstrate that all liquids have different density and we made some hypotesis about what would happen if we put in a same pot water, oil and alcohol.
Some of them said all the 3 liquids would mix together, some of them said just water and alcohol would mix and others said all 3 liquids would stay separated.
So we did the experiment in class, and as water and alcohol are both transparent, we coloured water with colour red and alcohol with colour blue.

For the experiment, we needed:
- 2 plastic glasses
- Bottle of oil
- Bottle of alcohol 96º
- Water
- Blue and red food colouring
- Spoons

First, we coloured the water with red food colouring. Then, we coloured alcohol with blue food colouring. Then, we added in the water glass, the oil and we could see this liquid floats on the water. Later, we added carefully the alcohol in the same glass and we could see this liquid floats on the oil and on the water.
The result, as you can see, was successful! We had in a glass 3 different liquids, separated by colours red, yellow and blue. 
So kids learnt that water has more density than oil and alcohol and that makes them float on it.
They enjoyed the lesson a lot!!!



Experiments in 1st grade

This week in 1st grade, pupils have been working about materials and we have done some experiments all together. They could smell, touch and see different objects and materials and we could see some reactions and different mixtures.
Kids enjoyed it so much and now they want to try to do it in their homes!
