“Am I living?” asked Cloe (7).

Many thanks team. You are right there was a question about clouds  and if they were living. Think about what living means for you and for other things that might be living.

Do you think that plants, rocks, clouds, germs, the air, birds, trees and you are living?  You might not think that a tomato is living BUT does it contain seeds? Think about seeds and what happens to these non-moving, non-growing things. Are they living? So put them in some water and give them some soil, what happens?

Miwah (7) asked ” I hit a drum and it produced a banging sound. How did it do that?”

Miwah, what a great question. It really needs some thoughts from my team.

 

So Miwah what are your thoughts? What happens to the rice when the sound  occurs?

Is there anything around the rice? If there is will that behave in the same way?

Think, ask questions, see if there are links. That is what science is all about.

Beatriz (7) asks “What happens to the the light at night?”

How do we tackle this question Beatriz? Lets tackle it by looking at light being used.

Let us see if we can make light move around a table. For this experiment you will need 3 plastic mirrors some plasticine and a torch. Light can be ‘bounced off’ an object so can it be bounced off mirrors?

So your task is to bounce the light from the torch around the four sides of the table. Think about what you did to make it happen.

Also let us look at shadows. Collect a variety of objects, a torch and a screen (maybe mounted in some way). Shine the torch at the object, what do you see on the screen.

Why do you think the shadow is formed? Can you change the shape of the shadow? Can you get more than one shadow?

Makeda (7) asked “How does the electricity make a magnet?”

Makeda what a great question, and my answer is, I don’t know. We know that electricity can make a magnet or even give a wire magnetic properties. There are other things which we know but it’s a bit like gravity. We know that big things, like the Earth and the Sun attract smaller things – the Sun attracts the Earth, the Earth attracts you and me BUT we do not know what gravity is, we just know what it does.

So I asked my friends about this.

Absolutely, thank you friends. Electricity is linked to things called electrons that are attached to other things called atoms that make up all of the things that we see around us, and us.

There are some special materials that you might have discovered called ‘metals’. Metals allow the stuff which we call electricity to flow through them. In metals the electrons carry the electricity and when they start moving they not only start moving the electricity there movement creates a magnetic field.

So lets carry out some experiments to investigate electricity and magnetism.

Let us make a simple circuit with a battery and a switch  and add a compass, close to the circuit.   Why a compass? A compass is a very small magnet and will detect other magnets by trying to move towards them or away from them. Switch on the circuit and see what happens. Switch off and again see what happens.

 

Let us know what you saw.

“If a cow ate only strawberries would it’s milk taste like strawberries? was Reginalds (grade 2) question

It is amazing that a cow has four stomachs like sheep and goats. The four stomachs facilitate the process of breaking down the grass into an edible, consumable, foodstuff.  Reginald, I am sorry that I cannot suggest an experiment to test your interesting thought. Most of the strawberry you eat is organic fibre and cellulose in nature. The sugars and flavouring are quite volatile so I would imagine (don’t know) that they would not survive the four stomach processing. I am happy for you to come up with some additional information.

“Does sound bounce?” asked Molly (7)

Molly, this seems to be a question that we could investigate. I have asked my team about it.

You will now have to think of some experiment to test the ideas that my friends have come up with. See if you can get a plastic mirror and maybe a sheet of cardboard. The next task is how to see if you get a bounce. You will probably need a friend , a cardboard tube and a device to make a sound (bell, buzzer, horn or something else). Your friend can ring the bell in front of the tube and you can  then listen to see if you can hear a bounce from the mirror or cardboard. Try it and then try it again, see if you can make the test as fair as possible. If you can get it to work, try with other surfaces, paper, carpet, aluminium foil. Have fun.

Let me know how it went.

Tippy (5) asked -“Both my parents have brown eyes how come mine are blue?”

Tippy. Many thanks for your question. I shall not ask why you have asked it! It was an interesting question so I asked my friends to comment on it here, are their thoughts.

 

Many thanks team.

Tippy, one of my team mentioned the word ‘genetics’ . Genetics is all about people investigating how we become who we are, Wow. We have all come from a mum and dad (parents) and because of this we inherit (get) things from our parents which make us, us. I , for instance , think that I get my hair colour from my parents and the size of my feet (my parents had my hair colour and small feet). My brother inherited different things, height and eye colour.

Eye colour is something that like height is not inherited directly from parents or an individual parent. It could be inherited from your grandparents, AND even then the chance of linking it directly to a parent or grandparent is open to chance.

Tippy. I hope that your parents can ‘try’ to relay this answer to you. You could also carry out a little investigation of your own, good scientific practice, try making a list of people in your extended family and the colour of their eyes. You could also look at the eye colour of your friends, to find out what is the most common eye colour?

Imran(7) asks “Why do plants need soil?”

Imran, many thanks for your interesting question. I have some thoughts but I will start by asking my team.

Thanks for that team. I have had some thoughts about some of the things that MIGHT be needed by plants to help them grow. You can see my thoughts on one of my SMS pages I got 8. See how many you can get before you see my list. Did you get as many a me? Do you think they are all correct? Are there any more? Let me know by clicking on the ‘Reply’ button below.

If you are happy with your answers then how could you test them, fairly?
For example how do you do a fair test on the effect of light/darkness on a plant? What do you vary and what do you keep the same?

Good luck. Let me know how you got on.

Walter Jr. (Grade 2) asks “I’ve heard the Sun revolves around the Earth, but I’ve also heard that the Earth revolves around the Sun. Which one really happens and how do we know?”

change-mind

My turn now. The astronomers at that time had noticed some strange behaviour when they were looking at the planets. For example, when they looked closely ( over many days) at the the path that Mars was taking in the night sky they were surprised to find that it suddenly started going backwards for a short time before continuing on a forward path. It did what astronomers call a ‘retrograde loop’ .  This could not be explained by a model where the Earth was the centre of the Universe with everything orbiting around it. It could however be explained if the Sun was the centre of our small universe(Solar System) and the Earth and the rest of the planets orbited it. The retrograde loop observation is then explained by the different orbits that each planet makes around the Sun. See an example in this link.

Ciera (7) How did people first appear on Earth?

Ciera, many thanks for the question. I have decided to try to answer your question myself rather than ask my friends. They can be confusing sometimes.

I think that the best way of describing how people first appeared on the Earth is that it happened very, very slowly. We would probably not be able to recognise the first people as people like you and me. It is likely that they had a lot more hair than we have. Maybe because they lived in a much colder part of the world and they would not have houses to live in. They would however be able to talk to each other, in their own language, they would walk in an upright way, not like chimpanzees, They would be able to hunt for food and probably live in groups.

Slowly, ever so slowly they would change (evolve) and become more like us.

It is thought that the first humans appeared on Earth about 150,000 years ago.
