Free Museums: Way More Choice Than You'd Think And How To Really Watch Seeds Grow

Local Museum

Local museums are often free to enter and ask for only a donation, just pay as much as you feel able too. If there isn't one in your area you could try a trip to a larger town or city. Money Saving Expert has a great interactive list here of all the free museum’s and galleries in the UK (scroll down past the map of the UK for drop down area menus). There's a huge variety on offer from pumping stations and Victorian police cells, to modern art and dinosaurs.

Watch Seeds Grow

You will need:

  • A clear glass or plastic cup
  • A seed (sunflower or beans work really well)
  • Thick absorbent paper or blotting paper
  • Scissors
  • Cotton wool
  • Water

How to do it:

  • Roll a tube with your paper, cutting it to shape so that it will fit inside the cup from the base to the rim all the way around, put it in place.
  • Stuff the inside of the paper tube with loosely packed cotton wool.
  • Place your seed in between the paper and the inside of the cup about 2/3rds of the way up, so that you can see it from the outside.
  • Pour water into the cotton wool, so that the water level inside the cup is about 1/3rd of the cup (don’t cover the seed), and all the paper and cotton wool stays damp.
  • Put the cup somewhere dark and leave the seed to grow.
  • You can check on the seed every few days to see how well it is growing as well as topping up the water. As the buds at the top develop into a small plant with leaves the plant will start to need light and it’s time to move the plant into a flowerpot.

If You Go Down To The Woods Today, Your Child Can Eat Jelly And Become An Arborist




Teddy Bear’s Picnic

Gather a few favourite teddies in your child’s back pack, a picnic blanket, plastic cups and saucers, a few cucumber sandwiches and some juice then head to the park for a teddy bear’s picnic... or the living room floor if it won’t stop raining!

Tearing up jelly - easier than it looks!
Combine it with a bit of baking by making individual fruity jellies for a picnic pudding:

  • Small jelly moulds can be found cheaply in supermarkets and poundshops but if you haven't got any kids plastic cups work really well. 
  • Simply make up the jelly - kids can help cutting it into cubes or stirring the hot water until the cubes dissolve. 
  • Chop up a few pieves of fruit (not kiwi, papaya or pineapple or the jelly won't set) pop them in the bottom of each jelly mould/cup and then pour the jelly on top. 
  • The jelly will take a few hours to set, so best to make it first thing or the night before.

How Old Are the Trees In Your Park?

You will need:                                                                                                           
  • A fabric tape measure (or a paper one from Ikea)
  • Some trees
  • A notebook and pen
How to work it out:
  • Take the tape measure and wrap it around the tree trunk of your chosen tree to measure the circumference.
  • Because of the average rate of growth of your average British tree, the tree will be roughly as many years old as it is inches around the middle, or the number of centimetres divided by 2.5.
  • Try measuring other trees to compare, put the tape measure at roughly the same height you measured the first tree at.
  • Are all the trees in the park a similar age? Were the trees all planted at the same time, or were groups planted at different times?

We're Going On A Bug Hunt, Finding Fuel For The Sport Of Kings: Snail Racing

Bug Hunt

Get your wellies on and take your camera out with you to look for insects high and low. Extra points for spotting anything you can’t name straight away. Take a picture, and look it up in a library book on bugs or on UK Safari. Remember we'd love to see any photos you have! 

Is it a Grey Dagger Moth or a Brown-tail? We can't decide.
Email them to lfwstubbs@gmail.com. Great places to look are the underside of leaves and under fallen wood.

Take it further:

  • What types of insects have you found? Are any of them rare or only found in your area?
  • Collect the pictures or drawings you have made in a book and record the place and time of day you saw them.



How To Put On A Snail Race
Number 4 races to victory.

You will need:

  • A plant pot
  • Paintbrush
  • Bright coloured non-toxic paint (Our DK kids science guide recommends enamel paint, but we're using washable poster paint)
  • Flowerpot

How to set it up:

  • Carefully collect snails from around the garden or local area – they can easily be found in damp places after rain and first thing in the morning. Pick them up gently by the shell.
  • Paint numbers or names on the shells, be careful not to get any paint on the body of the snail and to hold the snail carefully.
  • Stand the flowerpot up and put the snails in the bottom.
  • Wait to see which snail makes it first over the edge of the flowerpot!

Why You Should Go To The Library and How To Make Rain A Bit More Exciting


Libraries

Last week saw the opening of Story Lab this year's Summer Reading challenge! Encourage your kids to read 6 new books over the summer and they could win prizes! Younger children can earn certificates too with the Bookstart Bear Club.

Libraries are brilliant - they're free, warm, dry and keep rotating their stock regularly. The staff are keen to help and if you're utterly forgetful like me ask about fines - many authorities don't charge for overdue returns on children's books anymore.

Have a look at the noticeboards too, library story time sessions often still run over summer and sometimes they have extra weekday activities too, ours offers a range of afternoon craft sessions either for free or a small £1 charge.

Libraries have internet access, sometimes free, particularly for children. As well as: computer skills courses for adults; puzzle, magazine and book swapping stations; daily newspapers; child friendly reference books for when you want something a little more succinct than wikipedia; access to information about local services and plans; dvd rental; large print and audiobooks; board books for babies; colouring to keeping small children entertained while you browse and automated machines so your child can check books in and out themselves.

Plus hundreds of new stories for both the kids and you to get stuck into.

Make a Rain Catcher

You will need:
  • A plastic bottle
  • A stick or wooden spoon
  • Scissors
  • Sticky tape
  • Pens and a permanent marker
  • String, wool or fabric strips
  • A small spade
  • Ruler 
  • Notebook and Pen
How to make it:
  • Cut the bottom off your plastic bottle and throw it away, you want the top section with the lid screwed on tightly.Where you have cut through the plastic the edge may be jaggered and sharp - try covering it over with sticky tape.
  • Decorate the bottle with the pens and the top of your stick with knots of colourful wool or fabric.
  • Use the ruler to make marks every 1cm along the length of the stick.
  • Dig a small hole in the garden and put your plastic bottle inside, lid down.
  • Wait for it to rain. Once water has collected inside you can put your stick inside and count how many marks the water has covered to see how much it has rained.
Take it further:
  • Can you collect more rain in different parts of the garden, or in different shaped containers?
  • Where do you see animals in your garden (slugs, snails, frogs, foxes, cats) and is more rain collected where they like to be or less?  
  • Use the internet to compare rainfall in your garden with average amounts for the area or country.
  • Decorate the wooden spoon water-measurer as a person.

Some Days You Have To Wander and My Favourite Bit Of Science Ever

The Best Way To Find Something Exciting Is To Explore

Take a bus to the next district, town or village and ask at the Library or Tourist Information office for a local map, go somewhere you've never been before - a different park, library, garden, museum or family pub that you didn't know was there. Let your kids be your guide, buying tickets and reading the map.

Best Science Ever: Colour Changing Plants

You will need:
  • A white or pale coloured flower with a reasonably long and thick stem - a carnation works well.
  • A sharp knife
  • 2 hi-ball glasses, or other tall thin containers
  • Water
  • Food colouring
How to do it:
  • If your flower in shop bought, cut an inch or two off the bottom of the stem before you start.
  • Fill both glasses 2/3rds full with water, then add a few drops of food colouring to one glass. Put them next to each other in a sunny spot, as close together as you can.
  • Then cut the flower's stem in half lengthways from the bottom to about 2/3rds up the plant.
  • Put the flower into the 2 glasses of water, one half of the stem in each.
  • Leave for about 2 hours, then see what's happened.
Take it further:
  • What happens if you add food colouring to the other glass?
  • Can you use several glasses and flowers to make different colour combinations?
  • Do some types of flower work better than others?
  • Does anything else change how quickly it works?

Love Your Local Park and How To Make Your Own Really Truly Floating Boat

Since the weather is going to be beautiful for most of the UK this week, this week's ideas are all about the outdoors and water.

Local Park

Get reaquainted with your local park. Make the most of the early morning quiet if your children are small and pack up your usual lunch in a coolbag for a picnic.

Boats

You will need:
  • a small, light waterproof tub (wash out a margarine tub, yoghurt pot of fruit tray with the holes covered)
  • a small stick
  • blu tac
  • piece of paper of fabric
  • scissors
  • sticky tape
  • pens or pencils.
Extras:
  • string
  • fine wire
  • an electric fan
  • toys
  • small pebbles
  • hosepipe
  • plastic sheet
  • stream with a bridge and ford

How to make it:
  • Make sure the tub is waterproof by covering any holes with sticky tape.
  • Cut a sail out of paper of fabric and stick it to the stick with sticky tape.
  • Decorate the tub and sail with the colouring pens.
  • Put a blob of blu tac in the centre of the tub and push the base of your stick-sail into it.

Make it more fun:
  • Can you make your sail adjustable and your boat really sail?
  • Are your boats strong enough to carry cargo? How much?
  • Make more boats and race them - either drop your boats into a stream from a bridge and race them downstream to a ford, you should be able to collect the boats at the ford without entering the water but be prepared for lost boats! (WARNING: Please be sensible playing near water, even small streams can be deceptively fast flowing and riverbanks banks steep and slippy - never allow children to play in or near streams unless you are sure that it is safe.)
    • Or make your own stream, put the plastic sheeting down in your garden, position your hose at the highest point and turn it on so that the water flows down the plastic sheet. You can use this top position to set the boats off from, and the end of the plastic as the finish line. (WARNING: the plastic will be very slippery!)
