This term in science we are focusing on ELECTRICITY! We have spent a lot of time understanding the 5 different sources of electricity. Do you know the 5 types? Okay we will help you out there's
1) Mains power from a power station
2) Wind Turbine
3) Water Station
5) Solar Power
From here we looked at how to be safe around Electricity. As you know it is very dangerous to play around with and being safe is very important. Using an interactive game online, we designed our very own posters for the house. In our pairs we chose an area of the home either indoors or outdoors and gave suggestions on how to keep yourself safe. We discovered its everyday simple things such as turning off power points when not in use, making sure the cords aren't across the floor, keeping water away from electrical goods and the lists went on and on. Our posters look fabulous hanging from the ceiling and enabled us to make safe choices when using electricity.
Now that we understand the correct and safe method for using Electricity we were very excited to make our very first circuits. We discovered that in order to have a complete circuit you need the following components:
Using these three components we made our very own circuits in small groups. Then we drew this into our books. This is when we discovered that there is actually a scientific method for drawing circuits using symbols. Do you know what the symbols are for a bulb, battery and a wire? From this we then started on a challenge activity. Using a scientific drawing of a circuit we had to recreate it in our groups to first discover whether or not it would actually work. Many of the circuits were missing components are therefore wouldn't work. Our challenge was to add the correct components to the circuit to make them work. Well I guess we must all be great scientists in the making, as every group was able to correct their circuit so that it worked. Below are some photos of this exact experience.
Making a circuit
After Tuesdays exciting trip to the science museum we had a look at the website. On this we found a section of science experiments that we can do at home using everyday items. On Thursday some children helped to prepare the ice by dying the water and filling up the balloons. Its not as easy as it looks but it is possible. After a night in the freezer we had three large frozen balls ready to try our science experiment on.
After we all had touched the ice, felt the coolness, discussed the texture , we then placed water on one, salt on another and nothing on the last one. We then wrote down some ideas on what we think might happen over time. Below are a sample of our ideas.
