Twinkle, Twinkle, Little Star...

 For our next science activity we are going to be learning about the stars and modelling some constellations!

We will be releasing this activity on the Surrey Libraries Facebook page on Thursday 19th November at 4:30pm. 

For this activity you will need:

• Pipe cleaners
• Some beads
• A pen or a pencil

You will also need to print this worksheet that can be found on the Super Coloring website

Make a Camera

 The type of camera we are making is known as a camera obscura, and is a precursor to the modern camera. It works in a similar way to a pinhole camera but instead uses a lens. These objects have been used for hundreds of years with examples dating back to the 17th Century.

The first thing that we are going to do is take our square cardboard tissue box and on the side opposite the hole, we are going to draw around our kitchen roll tube. We are then going to cut out this circle that you have drawn. 

The next thing that we are going to do is tape your magnifying glass to one end of the kitchen roll tube. You will want to make sure that you use lots of tape to make sure that it stays in place 

We are now going to draw around the box, onto our sheet of tissue paper, and cut out this out. This piece of tissue paper is going to go over the hole in the top of the tissue box. Make sure that you tape it down tightly over the hole in the box and that the tissue paper is not wrinkled.  

You can now push the kitchen roll tube through the hole in the bottom of the box. Your camera is now ready to test. Point your camera at a place where there is a lot of light and you should start to see an image appearing on the tissue paper, but it will appear upside down. You can move the kitchen roll tube in and out to help focus the image 

The way this camera works is that light passes through the kitchen roll tube and into the camera and focuses on the tissue paper. Light travels in a straight line which is why the image will appear upside down. The lens (the magnifying glass) has a fixed focal length, so by moving the kitchen roll tube you can help focus the image.

Glow in the Dark Jelly

 

To make the jelly glow in the dark we will be using tonic water. Tonic water contains quinine and quinine glows under a UV light.

For this activity we will be using boiling water so you will need an adult to help you!

The first thing that we are going to do is put our jelly cubes into our jug. We are then going to add one-part tonic water and one-part boiling water to the jelly cubes and stir it until it dissolves.  (If you look on the instructions on your jelly packet it will give you measurements on how much water to add)

You can then pour the jelly into your moulds and you will then need to wait for the jelly to cool and set 

Once your jelly has set you can turn off the lights and use your UV light. If you shine it at your jelly, it should glow in the dark. 

Some colours of jelly will glow to a greater or lesser amount than other colours so you may like to experiment with different colours of jelly and see what colour glows the best. 

The video tutorial for this activity is available on the Surrey Libraries Facebook Page or the Surrey Libraries YouTube Channel

Get ready to glow...

Shadow Puppets

A shadow is formed when an object blocks the light, so it needs to be opaque or translucent. If something is transparent it will not cast a shadow as the light will pass straight through. 

The first thing that we are going to do is set up our light or torch next to a wall or background so that you have somewhere to see your shadow puppets. We are then going to cut a shape out of card and attach a lolly stick to the back of it with tape so that you can hold it 

Now if you put your card shape in front of the light then you will see the shadow on the wall behind. Try moving your shape closer or further away from the light and see what happens. Does the shadow get bigger or smaller?

Try moving your light closer or further away and see how this changes the shape of your shadow. Does the shadow get bigger or smaller?

Once you have had a play with a basic shape you can try drawing and cutting out some other shapes out of the card. If you mount them on to lolly sticks, then you have something to hold so that you can move them. You can try making your own puppet show. If you have some split pins at home, you could even try making some moving puppets.
