They say the weather’s going to be unpredictable over the weekend, so here are some ideas for indoor and outdoor ventures.

1. Butterflies in the house. Wing your way to our Butterfly Explorers exhibition. Just this week some beautiful new species have arrived. The vibrant zebra butterflies are already making their presence felt in the butterfly house and the shy glasswings are still hiding out, but in about 9 weeks these will be much more noticeable. Did you know the zebra butterfly (right) was declared the Florida State Butterfly? And that if you ever decided to eat a glasswing it would have a nasty taste (due to the poisonous sap it sucks on heliotrope leaves). Inside the butterfly house, the vegetation is thriving with bright bromelias and milkweed. Also look out for the peanut plants, a hit with the blue morpho caterpillars. Outside in the British garden, all the border seedlings and nasturtiums are really starting to show. Kids are loving the outdoor treehouse, log pile house and maze in the garden area. So let’s hope the sun shines for some of the weekend.
2. Butterflies in the cocoon. Continuing on the butterfly theme, and to check that you’ve actually learned something at Butterfly Explorers, head into the magnificent Darwin Centre Cocoon and spend some time at the ‘Organising nature’ butterfly interactive display. Have fun using the touch screen to play at identifying butterfly species. There are lots of fun interactive games and displays in the Darwin Centre. At the Darwin Centre you can also catch a family show or talk in the Attenborough Studio, so check what's on. Browse the Darwin Centre Cocoon highlights on our website.
3. Wildlife in the garden. This is one of the best times to explore the Museum's Wildlife Garden and after the last 2 weeks of sunshine and recent rain, it's really a pretty sight with the apple blossom and bluebells. The latest excitement in the garden is that a family of foxes and little cubs have been spotted recently, but we can't say where as we wouldn't want them disturbed.
4. Life's a beach for a fossil fan. Discover the Jurassic Coast at the free Lyme Regis Fossil Festival (above). Over 20 of our Museum scientists will be there identifying fossils, and leading talks and walks. This popular family event mixes science with music and the arts, on the beach. 'Dead...And Alive!' is the theme of this year's festival, which celebrates the 2010 International Year of Biodiversity. Find fossils in fossil digs, go on 'fossilteering' walks and learn about the seashore. We celebrate some extraordinary fossils in our Species of the Day this weekend.
   
5. Walk on the wild side of Brighton. Head down to Brighton seafront and experience our free Wild Planet outdoor exhibition featuring some of the best wildlife images in the world. 80 panels make up this stunning promenade display of winning photographs from past Wildlife Photographer of the Year competitions.

It's time to say a fond farewell to Jimmy Doherty, his co-presenters, and the Natural History Museum on TV. The last programme of the Museum of Life BBC documentary is tonight, 22 April. But you can catch the series for 1 more week on BBC iPlayer. And our last episode talk and screening is next Wednesday on 28 April.

Tonight's final episode 6, 'A Collection for the Future', delves deep into the world of meteorites and minerals. In one of the highlights, presenter Liz Bonnin talks to our Museum mineralogist Alan Hart about the casting of the famous Koh-i-Noor diamond, once the world's largest diamond and the size of a hen's egg. Here in our Vault gallery, visitors can actually view 2 replicas of the cut and recut Koh-i-Noor diamond (right).

Other tasty titbits in tonight's programme include looking inside a shark specimen without damaging it, some cutting-edge techniques that scientists are developing to investigate the Museum's collections in future, and Sir David Attenborough on the Museum's future role.

To find out more about tonight's episode and the whole series, visit our Museum of Life website.

For those who need more, there is a book of the series available from our Museum shops and a DVD on the way.

Happy Earth Day.

Our lovely Wildlife Garden has opened for spring and welcomes visitors on Sunday 11 April to its Yellow Book Day event.

Yellow Book Day is part of the National Gardens' Scheme to open gardens for charity.

At the daytime event, explore a bird hide installation by pastoral feltmaker Anne Belgrave, where you can try and spot some of her felt bird sculptures dotted around the garden. (With the help of some bird ID charts to hand.) One of her pretty creations is shown here on the left.

Become a bird detective and see if you can identify real species in the garden too. Recently a jay, heron and a pair of nesting blue-tits have joined our familiar moorhens, blackbirds and robins.

As well as identifying birds, enjoy spotting some incredible pond life through a microscope and find out about the garden's frogs, toads and newts.

Walk through the meadows and enjoy the spring plants and flowers as you browse stalls selling wild flowers, homemade tea and cakes. It's a perfect spring day out and a breath of fresh air if you've been inside the Museum's galleries for too long! Have a look at our Wildlife Garden highlights slideshow for more of a glimpse.

There is a bird talk in the afternoon in the Attenborough Studio about the felt bird installation by the artist Anne Belgrave, and Katrina van Grouw from the Birds Section at our Tring Museum will talk about British birds and how to identify and encourage them at home.

Our species of the day celebrates the jay. Unearth lots of fascinating facts about this shy yet striking, acorn-eating bird you'll find near oak trees.
