How do you make a periscope template ks2?
Follow these steps…
- Cut along all the lines of the template.
- Take one half of the template, roll it into a tube and secure it with sticky tape.
- Take the other half of the template, wrap it around the first half and secure it with tape.
- Slot the mirrors into each end and tape them down.
- Now look through your periscope.
How does a periscope work ks2?
In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle. This sends light directly down the tube and onto the lower mirror. This mirror, also at a 45° angle, reflects light directly to your eye.
How do you make a periscope step by step?
Place a curved elbow joint pipe over each end of the pipe to make a periscope shape. Have the two openings point in opposite directions if you want to look around corners or over obstacles. Find two mirrors that fit the pipe. These mirrors must be small enough to insert each one into one end of the pipe.
How does a periscope work?
A periscope is an optical instrument that uses a system of prisms, lenses or mirrors to reflect images through a tube. At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer’s eye.
How do you make a periscope instrument?
Stand one carton up on a table, with the hole facing you. Place the other carton upside-down, with the mirror on the top and the hole facing away from you. Now you have a periscope! If you look through the bottom hole, you can see over fences that are taller than you.
How many mirrors are used in periscope?
A periscope includes two mirrors or reflecting prisms to change the direction of the light coming from the scene observed: the first deflects it down through a vertical tube, the second diverts it horizontally so that the scene can be viewed conveniently.
What is a periscope and how does it work?
Which mirrors are used in periscope?
The mirror used in periscope is a plane mirror.
What is a simple periscope?
A periscope is an optical instrument that uses a system of prisms, lenses or mirrors to reflect images through a tube. This simple periscope uses only flat mirrors as compared to the periscopes used on submarines, which are usually a complex optical system using both lenses and mirrors.
Can you make a periscope with KS2?
If you’re making a periscope with KS2 then look no further than this step-by-step activity which includes a handy periscope template. It is a lovely way to reinforce your lessons on science and the reflection of light.
What is a periscope for kids?
Periscopes. From the Centre for Science Education, and with support from Shell Education services, these materials help children to investigate light and reflection. A periscope is a simple device that enables children to see over walls or round corners. Rays of light hitting the mirror of the periscope are reflected twice.
How is light reflected through a periscope?
Rays of light hitting the mirror of the periscope are reflected twice. The beam of light is reflected through 90 [sup]o [/sup], because the mirrors are at 45 [sup]o [/sup] to the path of the light ray. Card mirrors are used to make the periscope as they are cheap and can be cut with scissors.
What is the best way to make a periscope?
Card mirrors are used to make the periscope as they are cheap and can be cut with scissors. This activity provides a template to construct the shape of the periscope out of thin card.
