Hearing and sounds (6th Grade)

Hello children!

In 6th Grade, we are revising the senses. We did a couple of experiments that you can do at home. They're easy, clear and fun.

MATERIALS:

EXPERIMENT 1:                                   EXPERIMENT 2:

              - A wire clothes hanger                                    - A can

                          - 2 strings                                          - A balloon

                    - Some salt / sugar               - Something to make strong noise 

                                                                 (we used a cover pan and a spoon)

EXPERIMENT 1:

- Make noise with the hanger (for example hitting it to a table) and listen.

- Make the same noise again but this time listen through the strings:

 You will hear a strong GONG!

That's because the sound waves can travel through air, liquids and solids. When we listen to the hanger through the strings, we receive this information through a solid. And solids can transmit sounds better than gases:

1- Solids

2- Liquids

3- Air

EXPERIMENT 2:


We built an EAR DRUM with a can and a balloon to understand how it vibrates with sounds:

Bones (6th Grade)

Hello!

Today we want to show you an experiment we did some days ago, when we were learning the Musculoskeletal System.

First, pupils were asked to bring bones in class. Attention! These bones had to be cooked, cleaned and frozen, for our safety work.

We could also see some cartilage.

Ariadna brought an enormous pig bone!

Once we had all the bones (most of them, chicken bones), we classified them into 3 groups:

LONG - SHORT - FLAT

After that, we broke a bone to see what it has inside: THE BONE MARROW; responsible for making blood cells.

Then, we put some bone in a jar full of white vinegar, and we waited for 2 weeks.

What happened to the bones when we opened the jars after 2 weeks?

The Skeleton (6th Grade)

Hello 6th Grade!!!

How was your Summer? I'm sure it was great!

Let's begin with a new and engaging unit: The Musculoskeletal System.

As you already know, you have lots of games to learn and practise on the "6th Grade" section from this blog. Here you have some examples related to the SKELETON, the first part of unit 1.

Have fun!

Welcome back!

Hello everyone!!!

We have a great news: SCIENCE is back!!!!

Are you ready for more challenges??? Let's start!!! ;)

Happy Summer!

Hello children!

It's been a hard but great year; full of new contents, experiments, activities, curiosities,  also exams (yes, it's true...)... 

So now... We deserve some holidays, don't you think?

I hope you have a fantastic Summer with your families and friends ;)

See you in September, with loaded batteries and lots of new Science Challenges!

Pregnancy: development of the baby (6th Grade)

Good morning 6th Grade!

Let's start the class with this beautiful video:

Male and female reproductive systems (6th Grade)

Click on the following links to learn more about each part of the reproductive systems, male and female.

Find the slideshows and click on them to see how the different parts work.

Liquids and densities (5th B Grade)

Hello everyone!

How are you???

Today we have to congratulate five pupils from 5th B Grade, for having done an experiment at home and brought them in class in order to explain and show it to us.

They poured different liquids into a container and observed that they don't mix because they have different densities.

Our scientific students are: ARIADNA, NICU, ROBERT, ORIOL and MIREIA.

Great job children, thank you very much!!!

Liquids and densities (5th Grade)

Hello everyone!

In 5th grade we are studying MATTER and its properties (mass, volume and density).

Today, we have done one experiment to notice that:

• Different liquids have different densities.
• Liquids with different densities don't mix. So, you can pile them creating a beautiful effect.

We used:

HONEY, KETCHUP, LIQUID SOAP, WATER, OIL and ALCOHOL (5th B)

HONEY, LIQUID SOAP, MILK, DISH WASHER, WATER, OIL and ALCOHOL (5th A)

Parts of a flower (3rd Grade)

Hello!

Third Grade pupils are studying the parts of a flower, and LILIUMS are perfect flowers to do that, because their parts are clearly visible. We strongly recommend you to get some and observe them, using a magnifying glass or, if possible, a microscope. Then, all the parts can be drawn.

LILIUMS:

 STAMENS AND PISTIL:

PETALS, STAMENS AND PISTIL:

 OVARY, OVULES AND STIGMA:

 STIGMA:

 STAMEN: ANTHER AND POLLEN:

Simple machines (6th Grade)

Good morning!

In 6th Grade we are studying the Simple Machines. Here you can watch a video of three of them:

LEVERS - PULLEYS - RAMPS (or inclined planes)

Reproduction of flowers (3rd Grade)

Hello 3rd Grade!

This is the video seen in class today:

Butterfly Life Cycle (4th Grade)

Hello boys and girls!

These days we are talking a lot about life cycles. As you know, the butterfly life cycle is very interesting.

Now, let's watch this beatiful video from National Geographic:

Our Newton Discs (4th Grade)

Hello everyone!

We have to congratulate the following 4th Grade pupils because they have created a Newton Disc at home. They are Ainara, Aina, Hajar, Hiba and Imad.

There are different version of the same experiment:

A part from creating a beautiful effect, we can prove that the rotating disc (coloured in yellow, orange, red, green, blue, indigo and violet) appears as white.
