Electrical Madness!

 Over the last few weeks, Year 4 have been looking at Electricity. Firstly, we looked at electrical and non-electrical objects. As a class, we organised a range of objects into whether they used electricity or not. Here is what we found:

Next, we used to iPads and took pictures of items in the classroom that use electricity. We then used our ICT skills to create a Pic Collage of all of the items that we found. Here are some examples:

Our next lesson was very exciting. We had the opportunity to create circuits. We were told everything we need to make a bulb work was on our table. If we made our bulb work, we attempted to add a motor with a fan attached to the circuit. Finally, if we made this work, we added a buzzer and tried to make that work. Here are some pictures:

We noticed that in our circuits, where there was one battering powering a bulb, a motor and a buzzer, nothing happened, even if the circuit was complete. So, this lesson, we looked at how we could correct this and we predicted that using more than one battery should give the circuit more power. We tested this by making a circuit with two bulbs and one battery, and a circuit with two batteries and one bulb, and we looked at which was more powerful. We found that two batteries and one bulb was more powerful. Here are some pictures:
