Good Morning! 

This is our new hamster, Dave!

Maths

Add two 4-digit numbers – more than one exchange.

Remember to make sure that your additions line up so that you are exchanging ones, or tens correctly

Now you know the story well and have thought about what is happening and why, write a postcard to Aaron Becker saying what you liked about the story – Remember to add some specific details about your favourite parts; use some of your word bank to write a few amazing sentences. Then add a picture on the blank side.

You can make up an address for the postcard. It might be fun to base it on the house that the girl lives in. What do you think her street is called?  What might the city or town she lives in be called?

 

Science - Space

Galileo Galilei was the first person to show that the Moon was not a smooth sphere but imperfect, covered by craters and mountains. By drawing the Moon’s surface at different times in the month when the angle of illumination would be different, he showed that changes in the light and shadow could be explained by the features on the lunar surface.

Today, astronomers know that the best time to observe the Moon is during the first quarter, or the first few days past the new Moon. At this time, although less of its surface is illuminated, the Sun’s rays strike the surface at a shallower angle creating shadows and enhancing the physical features.

When the Moon is fully lit, it is so bright that physical features become ’washed out’ and astronomers using telescopes would be dazzled.

Can you see any shadows on the moon?

You can see sections of shadow caused by the mountains on the moon, blocking the sunlight. These mountains lie in craters are the result of asteroid impacts on the surface of the Moon.

NASA Tour of the Moon

Still image for this video
Watch this video until 2mins 14sec. which shows the central mountain in the Tycho crater; this central uplift is formed during the impact of an asteroid with the surface.

Using plasticine or different objects build lunar mountains.

Then find a torch to model the light from the Sun and investigate what happens when light is directed onto your mountains.

Investigate changing the height of the ‘mountains’ and measure the length of the shadows produced.

  • What must you keep the same each time?
  • What will you change?
  • What will you observe and measure?
  • What do they think will happen and why?
  • What do your results show?

Challenge: can you predict where you think the shadows will be if you change the heights of the mountains or the position of the torch.
