What is this? (Scroll down slowly so you see the clues and not the answer until you have worked it out)
1) This thing can change shape.
2) It can appear and disappear instantly.
3) It can be anywhere, at any time.
4) Its shape can change before your very eyes.
5) It does not have any colour.
6) One of these things can follow you around.
7) Sometimes they can be scary.
8) Sometimes they can be useful.
9) They can move but they are not alive.
10) Without light they simply do not exist.
Task - seeing how the position of your shadow changes
Choose a sunny day and record your shadow (by asking someone to draw around it) at several different times during the day, writing down the time. Each time stand facing the same way with your feet in the same place (it might be worth drawing around your feet the first time you do this). I would recommend using chalk! Please send me some pictures if you can and write down what your notice once you have done this!
Note: A shadow from the Sun is never still, unlike those made by many other light sources. Since the Earth is constantly moving in relation to the Sun, shadows cast by objects lit by the Sun change shape continually from sunrise to sunset.
Of course, the Sun does not actually move at all. Shadows first thing in the morning and late in the evening are longer because of the angle of the Sun’s light to the Earth; the Sun appears to be much lower in the sky at these times. As the day progresses towards midday, the shadows become shorter as the Sun apparently ‘climbs’ higher in the sky to its peak. The same situation occurs on a seasonal basis, too: shadows at midday in summer are much shorter than those
at midday in winter, again due to the apparent path of the Sun across the sky.
Scarlett and I will be doing this activity at some point this week so I will post some pictures.
We will revisit "Forces and Magnestism" when we are back together as a class as there are some practical aspects of this subject it is just not possible to cover at home and it will be fun when we are ALL back together again!
For now, we are going to move on to our "Light" topic. Please find this week's activity below. I would really like everyone to complete this if possible!
Before you look at any information, could you find any examples of light sources around your house and/or outside or think of any others? Write a list of these and/or draw the different things you find. A light source is anything that gives off its own light, the most obvious example being the Sun. See what interesting examples you can come up with!
Please look at the information below regarding light sources. Remember: BE CAREFUL as some objects reflect light rather than giving off light of their own!
Some light sources are natural and just happen such as the Sun, whereas others are created by man such as fireworks. Attached is a table and some pictures for you to sort. You can cut and stick/draw your own pictures/table. You may add any other ideas you have to the categories too!
(If you wanted to do a Venn diagram with two overlapping circles, you can do as there may be an example that is both!)
This week we will be looking at Friction. What do you already know about this?
I have attached some information about this. You may want to look at the link below first. This has a video that is fun and informative and a quiz.:
Tasks you may like to carry out this week related to friction. (Take your pick):
Drawings with arrows
The video represents how friction acts in the opposite direction to the pushing force. We can represent the direction of forces using arrows like in the video and like we did in class with pushes and pulls. I would like you to do some drawings to show this related to friction like I have done in the example below. Here are some others you may wish to do: brakes working, skiing and walking up a hill but you can think of any you like.
Note how when there is less friction, you will draw a smaller arrow to represent this.
Walk along a smoother surface (SAFELY and not high up/taking care) wearing the following:
How easy or difficult was it to walk along/slide along and why do you think this? Why do we wear different footwear for different purposes?
Repeat the same activity on a rougher surface. What happens then and why?
(You may take pictures of yourself doing this and draw arrows on again).
Advantages and disadvantages of Friction in different situations:
Complete the attached activity thinking if friction is an advantage or disadvantage in that situation. For example, 10 tin bowling – friction would be a disadvantage as you would not be able to roll the ball as quickly or as far as easily.
Have a go at this activity if you can!
NOTE: Next week will be a practical investigation where different surfaces on a ramp are used so start to gather different things such as scraps of carpet, bubble wrap, corrugated card, sand paper, foil, paper – whatever you can find. These will need to be big enough to cover some sort of simple ramp. You will also need to find something to use as a ramp – this could be a long book or piece of wood that will need to be wide enough for a toy car/vehicle. You will also need a ruler and tape measure. I will put a video up showing what to do ready for next week.
This week in Science as part of our Forces and Magnetism topic, I would like you to look at the uses of magnets. Can you think of any uses before you watch the videos below and make a list of them? Watch the videos below, taking notes. My personal favourite is the cow one - you will see what I mean...
Once you have done this, your job is to make a poster/booklet about the uses of magnets. Think carefully about your title (you may include some alliteration). You may use subheadings then explain the different uses underneath these. You may also draw some pictures to help show their uses.
Remember to make your poster/booklet interesting!
Science Tasks - week commencing 11th January
Please find below some Science tasks I would like you to work on and complete. Recently in class, we had begun our Forces and Magnetism topic and although you won't be able to replicate some of the investigations I was going to do, I think you can certainly have fun doing some of the things we would have done in class!
Task 1 - Pushes and Pulls
Look at the "Pushes and Pulls information" and follow the instructions.
Task 2 - Rolling
Watch my video clip on what to do for Task 2 and complete the activity. (This will be uploaded in due course).
