On Friday (20th March) the whole school intends to have a safe viewing of the solar eclipse using pinhole projectors and cameras. This will be a memorable experience for many children as they occur so infrequently. Any spare cereal boxes (or similar) would be greatly appreciated (please send these to Miss Harfield). Watch this space to see how we get on!
Solar eclipse viewers:
If you would like to make solar eclipse viewers in preparation for Friday morning’s eclipse, you may find the following useful:
The pinhole viewer.
Pinholes allow light through them and can create an image like a lens. Make a small hole in a piece of card using a compass or other sharp-pointed implement. Standing with your back to the Sun, position another white card behind the one with the pinhole so that the Sun projects an image onto it.
An alternative method uses a cereal box or something similar. Make a pinhole in one edge, point it towards the Sun, and a tiny image will be seen projected onto the inside of the box. A piece of white paper or card placed inside will make it easier to see.
Take an ordinary kitchen colander and stand with your back to the Sun holding it in one hand and a piece of paper in the other.
The holes in the colander can be used to project multiple eclipse images onto the paper.
WHAT YOU NEED Cereal box Scissors White card or paper (same size as the bottom of the cereal box) Foil (approx. 10cm x 10cm) Sticky tape Glue Pin Ruler
Open the cereal box at the top and stick the white paper or card to the inside at the bottom of the box using glue. This will be the ‘viewing area’. Remove the two small side tabs at the top of the box and cut 4cm from each end of the two larger flaps. Fold the remaining flaps on top of one another and secure with sticky tape, leaving two rectangular holes A and B. Place the foil over hole A and secure with tape. Carefully pierce the middle of the foil with a pin, making sure to only leave a small hole. Stand with your back to the Sun, allowing the light to enter through the pin hole. Look through hole B to see an image of the Sun in the viewing area on the bottom of the box.
