Grade 3s Light up when it's Time for Science!

In Science, the Grade 3s have been learning about ‘light and shadows’. We carried out an experiment to see how the position and length of a shadow, made by the sun, changes over the school day. Read on to find out what we discovered…

You can also view our finished King Tut block printing patterns and read our revolting recipes, inspired by the recipe for Boy Soup in Tony Blundell’s ‘Beware of Boys’

King Tut Block Printing Patterns

We have completed our King Tut block printing patterns that we wrote about in a previous blog entry and have displayed them in the classroom. Don’t they look great! 🙂

Light and Shadows

Here in Provo, studying light and shadows is easy, we have plenty of sunshine!

Shadows are made when an object blocks the light from passing through. We set up an experiment to see how a shadow changes over the course of the day.

We each made a shadow stick and placed them in a sunny place outside. Every hour, throughout the school day, we went out and chalked the position of the shadow that the stick made. We also measured and wrote down how long it was.

We used our recordings to draw a bar chart to show how the length of the shadow changed over the day.

What do you notice about how the length of the shadow changed?

We saw that the shadow changed position and length. In the morning the shadow was long and it got shorter as the morning went on. The shadow was the shortest at 11:45 and then in the afternoon it started to get longer again.

We looked at some websites that helped to show us how the apparent movement of the sun across the sky, changes the position and length of shadows.

Take a look at our favourites. They are lots of fun and very interactive:

‘Beware of Boys’

We enjoyed listening to the story ‘Beware of boys’by Tony Blundell. It is about a small boy who wanders into the woods and is captured by a hungry wolf who says that he is going to eat him. “Raw?” the boy asks. The wolf is surprised. “Is there any other way?”

The boy suggests funny recipes that the wolf might use to cook a wonderful dish with a boyas the main ingredient, e.g. boy soup, boy cake. The wolf is sent off to bring huge amounts of ingredients, some very strange. Each time he is told that there’s one thing missing and is then sent off to find the ingredients for new recipe.

At the end of the story, we found out what some of those strange ingredients were for, and why the story was right to be called Beware of Boys!

The story inspired us to write our own recipes. Be warned…some are pretty revolting…
