What happens to your eyes when you die? asks Olivia (12)

You did suggest Olivia that the eyeball might explode when a person died.  This is very unlikely. Look at the eye image below and try to identify the muscles in the eye. they will be attached to the two things that are constantly changing in the eye.

There are muscles attached to the lens and the iris.

When you die, your muscles relax. This causes the iris muscle contracts when this happens the eye is said to dilate ….like the image below

This is probably what your eye would look like  when you are asleep. Thanks for the question.

“Why do metals always feel cold when I touch them?” asks Chen (8)

My question is, are the metals colder or warmer than the things around them? We need to test this question. So how?

We need find out if other materials behave in the same way.  We therefore need to test it with other materials, for example, wood, plastic, china and glass.

To make the test fair (an important part of my experiment) we need to make sure that all of the materials are at the same temperature at the start of the experiment. We can test this by taping a thermometer to the materials, leaving it there for a period of time (maybe 5 minutes) before touching each of them. Do they feel hot or cold? Do they feel like they are at the same temperature that you are.

What did you find out? If the metal, or other material did feel colder, or warmer, than the others then why?  Let me know what you think by filling in the Reply box below and post your comment or ask another Question . Anybody can do this.

“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.
