We LOVE our leaf identification booklets we made from printouts off of the Nature’s Detectives website.

We used these ones, cut them out, laminated the, punched holes, and then put a keyring through it.  And there you have an awesome little leaf identification booklet to take with you everywhere!  I keep ours in our ‘going out’ backpack so it’s always there if we need it.

We also have one for seed identification, you can use this one and do the same as with the leaf booklet.

Today A found some elderberries herself by picking off a leaf from the tree, matching it to the booklet, and then telling me what she found!  More blackberry and elderberry crumble coming!

The obligatory phone box photo

Fun with magnets at the Science Museum

And I just had to get my photo taken with this London plane tree in Hyde Park.  I love trees.

It was a great day, we walked miles and miles, and by the end, I thought my legs were going to fall off!  But it was so hot I didn’t want to take the Underground!  It’s so nice being above ground, and you can see everything along the way!

This is great for writing practice, math, and learning about flowers at the same time!  Staple together some paper, and have your child write a title on the front.

Then on each page, make a space for the name of the flower, the date, the height of the flower (bring a tape measure with you outside), and where it was found.  Have your child draw a picture of the flower below the info.

                       

On a yummy food note, I edited my recipe for my Sugar Free Granola Bars by doubling the amounts because you get a more normal amount that way.  AND today I did a little variation on it, only using part of the mixture as a test.  I put peanut butter in it and oh my goodness it’s awesome!  Next time, I’ll do the whole recipe with peanut butter added, and figure out what the measurements should be.  I can post it on here when I have it perfected.

Here’s a simple science experiment.  Fill a jar of water halfway.  Gently try and float an egg in the water.

The egg sinks.  Now stir 5 to 7 teaspoons of salt into the water until it dissolves.  See what happens if you try and float an egg in it now!

The egg sinks the first time because it is denser, or heavier than the water.  When you add salt to the water it becomes more dense than the egg, so the egg floats!

My brother sent us a pack of 12 sponges from Trader Joe’s for the girls to play with.  They were all dried and pressed really thin.  First they had fun building towers with them, but I didn’t get a photo of that.

Then we dropped them into a tub of water and watched them grow!

Afterwards, I put them on the radiator to dry and gave E some tongs to take them off and put in a pot, and back on the radiator again.

Who knew sponges could be so fun?  Well, I didn’t, anyway!

We found this in our science experiment book. The magnet at the top holds the butterfly in a hovering position.

What you need:

  • shoebox
  • magnet
  • paperclip
  • tissue paper
  • sciossors
  • glue
  • thread
  • tape
  • sugar paper/construction paper
  1. Make a butterfly shape from the tissue paper, and tape a piece of thread onto it.
  2. Decorate the inside of the shoebox however you want to
  3. Tape the end of the thread to the bottom inside of the the shoebox, so that it’s long enough to let the butterfly be about 1cm from the top indside of the box, but not touching.
  4. Put a magnet on top of the box on the outside, and watch the magnetic force hold the butterfly up, even though it’s not touching!
  5. Watch the butterfly wiggle around!

This picture shows our magnet wand.  We got it on Ebay along with some magentic marbles.

I dumped out the spare change jar and gave A some 10p coins to review counting by 10s, then 5p’s to count by 5’s, then 2ps to count by 2’s.

Little E liked lining them up.

Then I thought it would be fun to see if the coins were magnetic, with our super cool new Geomag, which everyone needs to have!  It was so cool!  SOME of them are magnetic and some aren’t!  So I had to google it.  I found this website.   Turns out, in 1992, they started using copper plated steel to make pennies, so since then, they’ve been magnetic!  (Click on ‘History of the Penny at the end for more cool info.) It was fun to sort through and see which stuck to our Geomag and make cool sculptures.

Seriously, I love magnets!
