Frozen Water Magic Science

Frozen has been popular around here, so I've been working on my ice powers!  See this picture?  I made the water freeze into a pillar of ice...instantly!


 

Ever since I saw "The King of Random's" video about freezing water, I knew my kids would love it.  Now that it's summer and super hot outside, ice activities are even more popular for our crew.  So, we set out to make water turn into ice!

And, since we've been playing with videos lately, I thought I'd share our experiment with you!  Detailed instructions are below.  If the video doesn't load, you can see it here.


You can also use cool ice powers to freeze water too by following these easy steps:

1- (Preparation) Place several water bottles in the freezer for about three hours.  You want the water to reach a freezing temperature, but not be frozen yet.  You can test a "tester" bottle by squeezing the water bottle very hard.  If ice begins to form in the middle of the bottle, you're ready!  If not, put it back in the freezer.  Ours were in the freezer for 3 hours and 15 minutes.

2- Fill a small glass bowl half full of ice.  Alternatively, you could place the bowl in the freezer too.  Crush a few cubes of ice with a hammer and place them in the bowl.  These will serve as "seeds" for the ice crystals to grow around.

3- Very slowly pour your super cold water onto the crushed ice, and watch your ice towers grow!

What's going on?

As water gets very cold, ice crystals will form when one of two things happen:  1- Water molecules will form ice crystals by latching on to other ice crystals (or seeds) that have already formed or 2- Water molecules get close enough to each other that they arrange as a crystal and other water molecules attach to the first crystals.  The crushed ice serves as ice crystal seeds.  You are pouring water onto the seeds that is cold enough to freeze...it just needs something to "grab" onto!

Extend the experiment!

How does spring water (which we used) behave differently than tap water?  Or filtered water?  What if you poured almost-frozen water into a chilled bowl and "planted" ice seeds in different spots?  What else could you try?

Backyard Bugs: Roly Poly or Potato Bug or Pill Bug or Wood Lice...

Whatever you call them, roly polys (or potato bugs or pill bugs or wood lice...) are everywhere!  They are great to learn about and fun to carefully experiment with!  Warning: This post has close up pictures of pill bugs!


 

So what is the deal with pill bug names?!  It can definitely be a bit confusing.  I will be calling them pill bugs, but let's take just a quick moment and talk about names and classification.  Remember how living things are divided?

 Kingdom, Phylum, Class, Order, Family, Genus, Species

Pill Bugs are in the Animal Kingdom, Arthopod Phylum (which includes spiders, insects, and crabs), and the Order Isopoda.  Isopoda includes literally thousands of species that look very similar, but some live on land and some live in the ocean.  The pill bugs that we see all over the world on the land are all in the sub-order Oniscidea, which also includes literally thousands of species (about 5,000 known).  There is no real order to the common names...pill bugs and potato bugs and woodlice and roly polys are all often used interchangeably.  I even learned a new one, Kellerassel, when I asked my friends on Facebook!  (Thank you Maggy!)  Some people like to differentiate sow bugs as isopods that cannot roll up completely in a ball while pill bugs can, but there is no real difference--just different common names.  Most isopods, in fact, cannot roll up completely.  The most notable exception are the pill bugs in the genus Armadillidum, which can even tuck their head inside their shell when they roll up.


Enough with the crazy names!  Let's talk about these amazing little critters!


Pill bugs are found all over the world and are perfectly safe to carefully hold and examine.
Pill bugs are little herbivores and are not picky eaters.  They often live in their food.  You may see small holes in leaves or other decaying plant matter that they made as they ate their way through their home.

While small, they have amazing little bodies:


Anatomy!  

See if you can spot these body parts on your pill bugs:

1.  Thick protective cuticle.  

2.  Compound Eyes

3.  Long Antennae

4.  4 Pairs of chewing mouth parts

5.  7 pairs of walking legs (in adults) or 6 pairs of legs (in juveniles).  "Baby" pill bugs get their 7th pair of legs after their first molt.

6.  Pleopods and "feathery" gill-like lungs

7.  2 Uropods.  Male uropods are longer than female uropods.

8.  A female carries eggs around in an egg pouch in the middle of her tummy.  Can you find a "pregnant" pill bug?  Once the eggs hatch, she continues to carry the new pill bugs around for a few more days.  When they crawl out of her pouch it looks like they are born live!


More Pill Bug Fun Facts! 

1.  Pill bugs have blue blood...like most crustaceans!  This comes from having hemocyanin in their blood.

2.  Many pill bugs live 2-4 years!

3.  Pill bugs "molt" in two steps:  they shed the back half of their shell 2-3 days before the front half!

4.  Pill bugs can drink from their mouth and their anus!  Uropods can sweep water up into the pill bug if they need it!

5.  Pill bugs often eat their own poop to make sure they have enough copper in their body!

6.  Pill bugs need a moist environment.  They breathe through gill-like lungs on the outside of their body and will quickly die if they are not in a moist environment.

7.  Pill bugs are capable of parthenogenesis.


Try this at home or school!

1.  Raise pill bugs!  Set up a terrarium with dirt, leaves, branches, and water.  "Mist" it with a spray bottle if it starts to dry out.  

2.  Design an experiment to see whether pill bugs prefer light or dark habitats.  Hint: use white and black paper.

3.  Design an experiment to see what kinds of food your backyard pill bugs like best.

4.  Design an experiment to see what kinds of "homes" your backyard pill bugs like best.

5.  What else could you do to learn about pill bugs?

Remember to treat all living organisms with respect and care!

Squishy Bouncing Balls & 101 Kids Activities Giveaway!!


Making these squishy balls is an excellent fine motor and sensory activity.  When they're done, you can squish them, bounce them, or play tossing and target games with them.  They even work great as a stress ball or a distractor for a stressed out preschooler!

Making them is super easy and only requires three items:  balloons, flour, and scissors!  Now if you want to see how to use additional fun items (including how to make your balls bounce!), you'll have to grab a copy of the 101 Kids Activities...and it is so worth it!  More details about that are below!

Here's the easy how-to:

1.  Fill a balloon with flour.  We used about 1/4 cup of flour in our balloons.  Tie a knot to keep the flour inside.


2.  Take another balloon and cut a few small holes in it.


3.  Stretch the balloon with holes over the balloon with flour so you have two different colors on your stretchy balloon.  If you have preschoolers like mine, hold on to a few extra balloons to add to the ball when they tear the outside layer.  :)

4.  All done!  Time to play with it!  My kids favorite game was tossing them into a pack-n-play filled with stuffed animals that wanted to "catch" the squishy balls!



This super easy and very versatile project is one of hundreds of ideas in the new 101 Kids Activities book by Holly Homer and Rachel Miller from kidsactivitiesblog.com.  (Amazon affiliate link below)



101 Kids Activities is a fabulous collection of "boredom busters, pranks, crafts, games, simple science experiments," and so much more!  The authors have been blogging about kids activities for years (and you'll want to check out their website...it's amazing!!), and they have combined some of their best projects with loads of new ideas in a bright, colorful, and brilliant book.  

In addition to being a great resource for parents, this book can encourage your children to discover, explore, and exercise independence.  When my 7-year old saw the book, she picked it up, started perusing the pages, and then went and made a bunch of book marks to mark the activities she wanted to do first!  There are easily enough activities and extensions to keep you and your kids busy year round!

The book is divided into four sections:  Boredom Busters, Crafts, Games, and Simple Science.  It includes over 100 full color pictures, easy-to-follow step by step instructions, extension ideas, ideas for adjusting activities for older and younger children, clear supply lists, and a peek into the authors' lives as they share backgrounds on the activities and how they have used them.  Just reading the book is a delightful experience!

You can learn more about 101 Kids Activities on Amazon or on the kidsactivitiesblog.com website.  And to celebrate the book's launch this summer, they are giving away a copy here! Just enter below!!

Healthy Homemade Ice-cream Recipe

My preschoolers love sweet treats like ice-cream, but one of them has some serious sugar limitations.  I developed this ice-cream recipe so everyone can participate in the sweet fun...and everyone loves it!!



Letting your preschoolers help make the ice-cream gives you the opportunity to talk about things like solids, liquids, counting, colors, fractions, and more!  Cooking is excellent math time!


Ingredients:  

* 2 frozen bananas
* 8 frozen strawberries
* 1-1/4 cup almond milk
* (optional) small dash of cinnamon and/or nutmeg

Easy How To:

1.  Place all ingredients in a blender and blend until smooth.  I use the "ice crush" setting.

2.  If it is too thick to blend, add more milk.

3.  Serve and enjoy immediately!!

TIPS:

* Peel the bananas, cut them in half, and freeze the 4 halves in advance.  Then you can just pop them in the blender!
* Riper bananas are sweeter!
* This is best fresh--it can get way too frozen (or hard) when you freeze it!


This is a fabulous treat on a hot, summer day!  The best part is that it can double as a dessert or just a healthy snack!!

Backyard Bugs: Cicadas

The next bug in our Backyard Bug series is the cicada!


What is that buzzing sound?  Oh!  It's a cicada!  

Every summer we notice the cicadas start "singing" about the beginning of June.  And while I know some people who find the sound obnoxious, I look forward to it...almost as much as I look forward to not having to wear a jacket!  

Cicadas are large (often 1" to 2" long) insects with wings that have very clear veins in them.  They have two easy-to-see eyes and three very small "ocelli."  There are about 2500 species of cicadas, and they are very common in warm tropical and subtropical areas. 

Ocelli: small eyes

Cicadas are often heard before they are seen: during the hottest part of the day they make a loud clicking sound by vibrating part of their abdomen like a drum...over and over very quickly!  They have been recorded "buzzing" at over 120 decibels!  And even though both males and females have the same structures, only the males have been recorded buzzing.


An adult female cicada will lay her eggs on a branch or stem that she splits open to make room for the eggs.  When the eggs hatch, the nymphs will drop to the ground and dig a tunnel where they will live for several months as they grow and molt.  Their underground homes are usually between one and eight feet deep.  While they live underground, they will eat sap from tree roots.

When the cicada is ready for its final molt, it will dig its way to the surface and find a branch or fence to hold on to while it climbs out of its exuvia, or old exoskeleton.


This series of photos by Jim Dewitt show the process of the cicada climbing out of its shell wonderfully!


Most cicadas complete the above life cycle in two to five years.  One bizarre exception is the genus Magicicada. These cicadas life cycles take 13 or 17 years!  Most of that time is spent underground as a nymph.  The final adult stage only lasts about two months!

Cicadas are eaten by birds, squirrels, and cicada-killer wasps.


If you find a cicada, it is probably safe to hold. They rarely bite, and probably will only do so after it has rested on a person and mistaken the person for a tree branch.  The bite may hurt, but is otherwise generally usually harmless.  The cicada exuvia are definitely safe to hold!

With Your Preschooler:


Catch a cicada and observe it in a bug observation container.  Can you see the ocelli?  Do you find the veins in its wings?  Each large vein has both a nerve and a trachea.  Why do you think this is?  (So the cicada can feel things touching the wing and get oxygen to the wing muscles.)  Remember to release your cicada when you're done observing it.


Find a cicada exuvia and examine it.  Remember it is from the cicada nymph right before the adult emerged.  How many body features can you find?  How many legs does an insect have?  Exuvia provide an excellent opportunity for dissection, as they are discarded from the insect but still have interesting features!

Some insects, like crickets, can make a sound by rubbing their legs together.  The cicada, however, makes its noise by expanding and contracting muscles in its abdomen...like beating a drum.  Make your own drum using an empty oatmeal canister!

K is for Kingfisher Science Fun

K is for Kingfisher!!
Join us for some bird-watching, beak-studying, science activity fun!



These beautiful Belted Kingfishers can be seen near lakes and rivers throughout North America and their cousins, the Common Kingfisher (pictured below), can be seen throughout most of the rest of the world!


Aren't their huge beaks amazing?!  I remember the first time I saw one in "the wild" was actually in the middle of a city.  In a more calm neighborhood, you can walk right down to a river that runs through the city.  As I scanned the water for wildlife, I saw one perched on a branch staring intently at the water.  While I watched, it darted its beak into the water and came up with a fish!

Take a walk (or drive!) to a river, lake, or pond and see if you can spot any kingfishers!  Tell-tale features on the Belted Kingfisher include the white throat, the two "belts" or stripes across the front, the large beak, and the "spiky hair."   Keep an eye out for other birds that like to go fishing: herons, egrets, plovers, and killdeer are common throughout North America. What do their beaks all have in common?  How is that different than song birds you may see in your back yard or in a parking lot?

This fun science activity to reinforces the concept that birds' beak shape is specific to their diet, and it's great for strengthening those fine motor skills!  You can also adapt it for Montessori Baskets by placing all the supplies in small containers in a bin and letting your child experiment on his or her own!

Beak Shape Science Activity:

Supplies:

* a small pile of marbles or similar-sized rocks
* a spoon
* a straw
* tongs
* a bowl

Easy How-to:

1.  Tell your child that he is a bird and the marbles are his food.  To eat them, he needs to get them into the bowl.  He only gets one minute to eat.  AND (here is the catch...) he has to do it with a straw!  

2.  Hand your child the straw and bowl and time him for a minute.  See how much he gets to eat.  

3.  Ask him if he thinks a spoon or tongs would work better and let him try again.  Time it again, and see if he gets to eat more this time.



4.  Discuss how different birds eat different things.  A sharp pointy beak can cut through the water quickly and grab a fish.  A thick, sturdy beak can break open nuts or seeds easily.  

Note:  If you are teaching more than one child, you may want to hand 3-4 of them an eating utensil, let them try if for a minute, and then rotate or discuss what happened.

5.  What type of beak would you expect to see in a woodpecker that pecks holes in wood to get to insects?  What about in a pelican that scoops up piles of fish?  What about a chickadee that eats small grains, insects, and spiders?  What about a hawk or eagle that eats mice?  What about a hummingbird that eats nectar?  

6.  See how many birds you can spot in real life and observe their beaks!   Summer is a fabulous time for bird-watching!!

This post is part of the ABC's of Nature Series hosted by School Time Snippets.  This summer 26 bloggers are bringing you fun and exciting ways to explore and enjoy nature with your kiddos!  Be sure to follow along to see more outdoor fun!
