EXPERIMENTS WITH LIGHT

During the second term we are going to experiment with light and talk about its different properties and shadows.

Fluorescence or fosforescence?

Refraction

SCIENCE EXPERIMENT for 3rd cycle

Hello students,

today we start our weekly workshops. 
In Science Experiments we are going to learn about light and electricity, and we are going to practice with a Static and Current electricity experiment. We also learn about conductors and insulators. I hope you have fun and you learn a little bit. 

Learn about electricity from nurlorenzo

This is what we have done on the first day. 

Static Electricity

Current electricity

Let's build a catapult!

This is the model we're going to build in class.

Practice with simple machines.

Today we're going to practice with this simple experiments of a lever and wheels.

Simple Machines

Dear 5th grade students,
in this unit we're going to learn about simple machines. They make our life easier.

Simple machines change the size 
and direction of forces. 

A lever, a wheel, an inclined plane or a pulley.

Let's have a look at this video to have a better idea.

Floating egg experiment

The Salt Water Egg Experiment explains why materials (such as an egg) float more in salt water than in fresh water.

Will it float or sink?


Have you ever tried swimming in the sea? Did you notice that you could float more easily in the open waters than when you're swimming in fresh water or even in a swimming pool? This experiment will help you understand why!

Density tower experiment

Today we work with different liquids:

Dish soap, water, condensed milk, sunflower oil,  body oil and a grape.

We talk about what is going to happen when we pour them in a glass...

Some pupils say they will mix. Some pupils say they will stay separate.

Then they predict which one will stay at the bottom and which one on top.

This is what happened...

After that we watch a video to see what happens with other liquids.

After the experiment we see that

MORE DENSE LIQUIDS STAY AT THE BOTTOM, 

LESS DENSE LIQUIDS FLOAT.

Each layer is less dense than the one below it.

Flower colouring experiment. Part II

My flower turned blue.
Mine turned green.
And mine turned yellow.
And mine is half yellow half blue! !!

Flower colouring experiment

We need some white carnations for the experiment.
We cut the stem.
We add some food colouring drops in the water.
We mix some colours:
Blue + yellow = green
Blue + red = purple
Yellow + red = orange
Then we put the flowers in the bottle and wait for a couple of days...
See what happens...

Experiment: Changing colour of flowers

Dear 5th grade students,
This week we are going to do the following experiment:
Where does the water go when a plant is watered?
You can have a look before we start...

This time we'll need white flowers, food colouring, water and some glasses or plastic bottles. 

Experiment: Extract chlorophyll from plants.

In this experiment we extract chlorophyll from lemon tree leaves.
We need green leaves, some alcohol, some sugar, a mortar, filter paper, a funnel and a glass.
