Homemade Projector

This time we were studying THE EYE in Natural Science and we decided to make something related doing a Homemade Projector. We could experiment with the orientation and the size of the images that changed depending on the magnifying glass

Materials: Shoe Box, cardboard and paintings (for decorating), Magnfying glass, scissors, celo tape, white paper, smartphone.

1. Trace the shape of the magnifying glass on one of the short sides of the box and cut it out

2. Decorate the box

3. Tape the magnifying glass on its place

4. Place the smartphone inside the box, with the sceern looking at the magnifiying glass, and play a video in the highest resolution and brightness that you can and close the box.

5. Use a white paper in front of the projector to see the image.

We had to play moving the smartphone closer or further to the magnifying glass and do the same with the paper to find the perfect spot to see the image big and focused. We also realized that the magnifying glass turns the image upside down, like the lenses of our eyes do.

Can Plants Move?

With this experiment we want to see if plants can move because they want to. This could be caused by the interaction of plants with the sun, because they are living things and they interact with the environment. We will put the carrots upside down and see if the leaves grow on their normal direction or if they grow up looking for the sun.

Materials: One carrot with leaves, a small spoon, a wooden stick  and thread .

1. Cut 3-4 cm from the top of the carrot and cut the leaves leaving 2 cm of them attached to the carrot.

2. With the spoon empty the inside a bit { carefully }.

3. Push the stick through the carrot .

4. Hang the carrot with the leaves down with the thread .

5. Water it inside the hole and observe for a week.

Conclusion:  Our carrots died because at the weekend no one was in the school to water them, but we could see how some leaves that had just started growing, were growing up following the sun.

Onion Cells

With this experiment we want to learn how to make preparations for the microscope and be able to recognize the Cell Wall and the Nucleus of the onion cells.

Materials: onion, slide, cover, methylene blue and microscope.

1. Cut the onion.

2. Separate 3 or 4 layers.

3. Pick the skin between the layers.

4. Place a piece of the skin in the slide.

5. Put a drop of methylene blue in the preparation and leave it for 1 minute.

6. Place the cover and look in the microscope first with 4X and then with 10X.

We saw that when we look to the microscope in 4X we can see the cells of the onion in blue and when we look in 10X we can see a very little circle that it's call the nucleus.

Hello everyone, and WELCOME!

Hello World!

Welcome to our P6 Science Experiments blog!. You are invited to take a look at the news about our class activities. We have made groups to work together, do the experiments, write about how we prepare everything, the results we get and the conclusions we come to. 

We would like to hear that you try our experiments at home or in your own schools, also we will appreciate your opinions and also if you have got any suggestions to help us out.

So, let's get started as soon as possible. 

See you.
