For thousands of years, people used sundials to tell the time. The first sundials were used more than 3,500 years ago in Egypt. The sundial showcased in this...


Last week, some of you studied a shadow throughout the course of a day and you observed how it changed position.  In week 3, we will continue to look at shadows and link them with the time (before clocks invented, this is how people were able to work out the time of day and the first 'clock' was a sundial).  Watch the video, then click on the links to watch BBC bitesize and to explore the Espresso Light page.  After, look at the Powerpoint that tells the story about Peter Pan's shadow and it also shows you how to make your own sundial.


Finally, for our topic on Light, we would like you to find out the meanings of the words: opaque, translucent and transparent by watching the video on Espresso (we have made it easier to find this video by clicking on the stand alone link).


All the science powerpoints and worksheets from the previous weeks can be found by scrolling down the main Year 3 website page.




It has been really lovely to see how many of you have engaged with the Science topic and carried out the experiments on the best reflective materials and how mirrors can reflect light.


This week we are going to investigate shadows.  We have added a link to all the Espresso videos on the subject of light and, as we are concentrating on shadows, there is a powerpoint full of information, there is a powerpoint that helps you through your own shadow investigation and there is an optional worksheet if you wanted to study a shadow throughout the course of a day or you can carry out your own investigation by measuring your own shadow throughout the day and seeing how it changes position.  Have fun and we look forward to seeing your pictures of your shadow investigations.


Our science topic for the next two or three weeks is Light

Just before lock down happened, we were beginning our new science topic about light.  Some of us found out what we knew about light and shadow, that we need light in order to see things and that dark is the absence of light.  We also learnt that light from the sun can be dangerous and that there are ways to protect our skin and eyes.


This week we will look at the powerpoints to explore how light is reflected from surfaces and we will consider how some surfaces reflect light better than others.  Each powerpoint comes with activity sheets just in case you wish to carry out the experiments suggested in them (however, these activities are, of course, optional).
