For our next science activity we are going to be making Model Neurone Cells!
We will be releasing this activity on the Surrey Libraries Facebook page on Thursday 29th April at 4:30pm.
You can generate static electricity by rubbing a balloon against your jumper or even your hair! The tiny electric charge in this activity is completely safe.
The first thing that you need to do is blow up your balloon and tie off the end.
You can now take your balloon and rub it against your jumper for about a minute. This is going to generate some static electricity.
Now if you hold your balloon above your tissue paper snake you will see that it is attracted to balloon and will start to rise up towards it.
The reason this happens is because an electric charge is carried by tiny particles called protons and electrons. Protons carry a positive charge and electrons carry a negative charge. Charges of the same type repel each other, while different charges attract. When you rub the balloon, it picks up extra electrons, making it negatively charged. This causes the protons in the tissue paper to become attracted to the balloon and the edge of the paper picks up a positive charge.
You may like to try cutting some different shapes out of tissue paper and see how smaller/ larger shapes are affected by static electricity. Or you may like to see how other things react to static electricity. You might like to try turning on a tap, and seeing if the running water is attracted or repelled by static electricity.
The video tutorial for this activity is available on the Surrey Libraries Facebook Page
For our next science activity we are going to be learning about Static Electricity!
We will be releasing this activity on the Surrey Libraries Facebook page on Thursday 22nd April at 4:30pm.
For our next science activity we are going to be experimenting with M and M's!
We will be releasing this activity on the Surrey Libraries Facebook page on Thursday 15th April at 4:30pm.
We can make butter from cream. When we do this the fat in the cream separates, and produces butter and buttermilk.
To make your butter the first thing that you will need to do is half fill your jar with cream and then put the lid back on the jar. Make sure that the lid has been put tightly onto the jar. You may like an adult to check this for you.
The next thing that you will need to do is shake your jar. You will need to shake your jar for a few minutes. To start with the cream will start to thicken.
If you keep shaking a ball of butter will start to form in the middle of the jar. The liquid that surrounds it is buttermilk.
The reason this happens is because cream contains small amounts of fat cells. These cells stop the fat from forming clumps as they are separated by cell membranes. When we shake the cream the fat cells bump into each other, the membranes burst and the fat starts to clump together forming the butter.
The video tutorial for this activity is available on the Surrey Libraries Facebook Page.
