Good morning.

You're with Newsround this Saturday.

It's day two of the Anniversary Games in London.

Last night, Usain Bolt won the 200 metres on his return

to the track where he won Olympic Gold four years ago.

The Jamican has struggled with an injury, but last night

he proved that he's still got what it takes.

But Bolt said he's still got some way to go to be fully fit

for the Rio Olympics next month.

In training I'm doing pretty well.

Everything is going smooth, but after running the race,

I can tell that I need races.

It is just one of those things.

How are you going to do that, though?

I've just got to do like last year and was just run myself.

That's what I have to do, continue to train, continue

pushing myself in training, hopefully everything

will come together.

Formula 1 now and Lewis Hamilton has apologised to his team

after he crashed his car in practice yesterday.

Hamilton was OK but the crash allowed his team mate,

and rival for the title, Nico Rosberg to get

the best time of the day.

Scientists at the Sea Watch foundation are leading a week-long

campaign at the start of the summer holidays to get you guys

out and about around the UK to spot wildlife.

We asked Kathy from the Sea Watch Foundation to give us her top

Dolphin watching tips.

I am Kathy and I am the sightings officer for Sea Watch Foundation.

These are my top five tips on spotting whales and dolphins.

Number one, go somewhere with a really good view.

Generally we would say somewhere up high.

Bear in mind the safety with that, don't go to some high cliff edges,

but go somewhere with a really good view and take your parents along

with you, of course.

My top tip number two is take a friend with you.

It is quite intense work looking at whales and dolphins

because you are going to be scanning at sea for quite some time.

If you want to take a break and maybe have a snack,

it is good to have a friend there to take over from you.

My top tip number three is to just scan with your naked eye,

so just keep looking left and right and look around all the sea that

you can see, to see if there is anything happening.

And only when you see a wave break, bring up your binoculars and see if

you can actually see what that is.

My top tip number four is to have a look at

the animal in question.

You might not have a clue what you are looking at,

so just have a good look at it, try and use your binoculars and see

what there is there.

What colour is it?

How big do you think it is?

What does the fin on the back look like?

Things like this.

Then you can speak to us and we can help you ascertain what it was that

you were actually seeing.

We want to know about your casual sightings.

So, maybe you were walking your dog and you saw something pop-up

or if you actually go and do a specified watch for us,

to send that information back to us.

Even if you weren't very lucky and you didn't see anything,

we definitely want to hear back from you.

That's all from me, Newsround's back right here just after 12.
