The Skeleton and Movement

Watch this super video to help you learn the names of some of the bones in our bodies.

Handprints Survey

We are collecting the handprints of ALL the children and adults in our school. We will the arrange them in age order and see how the SIZE of our hands changes with AGE.

X-Rays

Above is one of a fantastic new series of images taken by Nick Veasey using X rays discovered by Madam Curie.CLICK HERE or on the picture above if you want to look at some more of these images.

As one of our houses is named after Madame Curie, you can find out more about this awe-inspiring scientist by CLICKING HERE

If you have time watch this old school film about the life of Marie Curie; it is absolutely fascinating.

Test On Vertebrates and Invertebrates

You have a test on vertebrate and invertebrate animals on Thursday 11th December.

You should know:

animals with back bones are called vertebrates;
animals without backbones are called invertebrates;
there are five groups of vertebrates: mammals, fish, reptiles, amphibians and birds.
each group has its own special characteristics;
we can use keys to help us identify and place the animals in different groups.

You can revise by CLICKING HERE to go to the BBC site.

Good Luck.

National Geographic Animals

This is a fabulous site for researching information about your chosen animals for your project. Remember to collect the information in the back of your books as your homework. Click HERE
You can also research your animals at the ANIMAL DIVERSITY site . Click here to visit it.

You can also visit ALL ABOUT ANIMALS to get details about 65 animals!
For excellent information on all the animals visit THE ANIMAL KINGDOM.

The project is due on Wednesday 10th December 2008. However I would like to see your information every week please! Thanks.

Animal Project

We are looking at how to CLASSIFY different animals into small groups. We have decided that all animals can be divided into TWO main groups:

Vertebrates ( animals with backbones) and
Invertebrates ( animals without backbones )

Homework tonight:
You now have to choose ONE VERTEBRATE and ONE INVERTEBRATE animal for your project. For tomorrow write the name of the vertebrate you have chosen on one page in the back of your science book. Write the name of the invertebrate you have chosen on the second page in the back of your science book. Begin collecting information on each animal.

Happy researching!

Making Circuits

Well done Year 4 for making circuits using basic materials in class.
http://windvane.umd.edu/images/animation/bigfanspin.gif
Homework: To complete the comprehension on Circuits. Due in Wednesday.

This week we will be using various components to make new circuits. These are the components we will be using:

connecting wires
cells
bulbs
motors
buzzers
switches

If you click on the picture below, you can find all you need to know for next week. Have a go!
Work your way through the information all the way to the quiz. See if you can make the five stars light up!

Electricity

Today we looked at different ways in which power companies generate electricity. Some power stations use fossil fuels and some use nuclear fuel. These are NON RENEWABLE energy sources. Alternative energy sources are wind, wave, tidal, hydroelectric, geothermal and solar energy. These are RENEWABLE sources of energy. Which one do you think is the best?
Click here to find out more.
The diagrams below are taken from the excellent EDF education site.

This is how the energy is distributed after it has been generated.

Want to be a genius? Take a look at what the Year 5 know about this topic! Click on the picture below to find out what you need to know for 11+ exams! ( You will only be tested on the particles in a solid and a liquid, not gases; that’s for year 5)

Topic 2: Moving and growing

You can revise this topic by going to the bbc revision site. Click on the dancers!

You can also test yourself on the human skeleton by clicking on the picture below.

So you think you want to be a doctor? Well in that case, see if you can learn the scientific names for all the bones. If you make the skeleton in this activity and then move your cursor on the picture, you can find out the “proper” names for all the bones! Impress me in the test!

How are vertebrates different from invertebrates? Click on the STARFISH to find out!

?

Click here to go to Animal ID, which will help you sort out some vertebrates and invertebrates.

Topic 4: Making keys

Click on the lock to let the knowledge flood in!

Use all the information in this revision sheet to see if you can make a key which would sort out the five different groups of vertebrates. You can use the information in this blog to remind yourself of how to make keys.

I hope you all revise well but have a great holiday as well. Make time to have fun !

Planning your Investigation

LO: Does the length of your stride depend upon the size of your leg?

Today we really enjoyed measuring the distance we walked in ten strides and then calculating the distance of one stride. We did this by dividing the total distance walked by 10.
We also measured the height of our leg, from the foot to where the leg joins the pelvis.

Homework Task for tomorrow:

You have to plan an investigation to see if there is a link between the size of your leg and the length of your stride.
This is explained in section 5 of the measuring sheet you have taken home.

You need to consider:

Which measurements to take?
How many measurements are needed?
How will you keep the investigation fair?
How will you make the investigation accurate?

You an also make a prediction in the comments or on your sheet as to what you think the answer will be!

Good Luck!

Farida Mannan

Skeleton Shakedown

I think you all know the skeleton pretty well now. See if you can put this poor thing back together again!

Click here

I hope you really enjoyed that. I dropped quite a few bones so I am glad that I am not a doctor!
See if you can remember the scientific names for all the bones. If you are going to be a doctor you will need them!

Good luck!
