Each year we learn about a human organ. This year, we focused on skin. We enjoyed building models of a cross section of human skin.
In February, we have been learning about Light, and how light can be affected by the medium it travels through. We have talked about how light moves more slowly through glass and water than it does through air, and the impact this has on how we see things.
Our Science experiment for the month was to try to make our own magnifying glasses. It was all hands on deck to try to make them, so we don't have any pictures of the process, but here is a picture of some of the most successful specimens:
The biggest challenges we faced were cutting perfectly compatible discs of plastic from old plastic bottles, and then achieving a perfect seal using a hot glue gun. We then had to fill the 'bubbles' with water, before testing their magnifying properties.
We observed that writing viewed through the water in the bubble appeared larger, as with a magnifying glass. Interestingly, writing viewed through the air bubble inside the water bubble, appeared smaller than normal!
The second experiment we did around the topic of magnetism was to try to make our own electromagnet. This involved using a battery and a length of wire to create an electrical current, and wrapping the wire around a nail to magnetise it.
We found it challenging, but all groups eventually managed to pick up varying amounts of paperclips with the magnets. We all observed the heat that was created by the electrical current, as we held the wires to the ends of the battery!
This month, we have been learning about magnets. We have discussed magnetic fields and last week, we performed an experiment to try to see the magnetic field for ourselves. We sprinkled iron filings onto a page, that was laid over a magnet.
We had mixed results - the pictures below show some of the examples that displayed the magnetic field most clearly.
During September, we spent a lot of time talking about classifying animals, and understanding the categories that scientists typically separate animals into.
Finally, we did some exploring of our own; studying a selection of creatures. The fish got the most attention, with some children really enjoying getting their hands in and exploring the gills, teeth, and innards! But the adventurous ants, with their attempts to escape their viewing box!, and the spider came a close second!
Afterwards we noted our observations in our science notebooks.
One of our first acts as Fifth Classers was to help Aoife in the set-up of the ICT Suite. Aoife had just taken delivery of 30 brand new chromebooks, and we got to be the ones to unbox them and take them for a test drive!
