Ocean/Beach Discovery Sensory Bin

While I’ve always been a fan of sensory bins, I haven’t used them too often in my classes with the tots.  That is starting to change as I’m seeing how popular they are with the littles… and their parents!  This ocean sensory bin is so fun and my own children have enjoyed it many times and now, so have the tots in my class.  Super easy to set up and encourages so much learning through play.

Here’s what you’ll need to get started:

  • Large bin (We’ve also used our water table)
  • Mixed blue beads (I grabbed a bag from the dollar store)
  • Bag of decorative river rocks (or collect some in your neighborhood)
  • Sea shells
  • Plastic sea animals (I really like these Terra by Battat Sea Animals from Target)
  • Water

Set up the river rocks on one side of the bin for the “shore” and the blue beads on the other side of the bin to represent the ocean.

Place some shells along the beach

Place some of the sea animals on the shore (such as the sea lion, turtle, crab).

Place some of the sea animals in the ocean (such as the octopus, sea star, sharks, eels, etc..)

Add water and your bin is ready for play!

 

Hand the bin over to your little superheroes and let them play!

My little guys had a blast!

The Science Behind the Activity:

This sensory bin allows children to have a sensory experience with different textures of rocks, shells, beads, toy animals as well as encourages them to get wet.  While playing with your child, ask them which ones like the water and which ones prefer the shore.  Do any of the animals like to eat other animals  For older children, you can bring up the topic of predator and prey and habitats.

Extension:

Follow up this activity with a book about sea animals, oceans, beaches.  Visit an aquarium or tidepools.  Or collect sea shells and rocks and sand from a trip to the beach and make a sensory bin when you come home to “re-live” your fun memories at the beach.

Earth Day Absorption Science

Water is a fantastic “chemical” to do science experiments and investigations with.  I love this easy water absorption activity, especially for the littlest tots.   Easy to set up with cotton make-up pads, some water and droppers.  Using blue and green water, this makes a perfect Earth Day STEAM activity.

Here’s what you’ll need to get started:

  • Small tray/plate or cookie sheet
  • cup of blue water
  • cup of green water
  • dropper
  • Round cotton pads

Show your little one a picture of the Earth.  We spent some time talking about our planet and where we live on the planet, that the blue was oceans, the green and brown was the land and the white were the clouds.

Next, I gave them a cup of green water, blue water, dropper and a cotton pad and told them to drip the colored water onto the pad to create their own Earth.

The tots LOVE droppers!

The youngest ones dipped their pads in the water or dumped the water onto their pads.

The older ones were particular about where to place the green and blue drops.

They were so proud of their Earths!

The Science Behind the Activity:

I love using droppers whenever possible as it is a great way to strengthen muscles in preparation for learning to write AND it develops fine motor skills, both of which are vital as pre-writing skills begin emerging.  It’s also a great way to watch how water gets “sucked up” by the cotton pad and to introduce big words such as “absorb” and absorption” to their expanding vocabulary.

Fizzing Jupiter

For those of you who follow my activities, you know how much I love my baking soda and vinegar experiments.  To be fair, the tots and my littlest superhero LOVE baking soda and vinegar so it’s not ALL about me 🙂

This one is a simple and easy addition to your space theme.  I call them Jupiters (even though my color mixing wasn’t as successful as Jupiter) but you could make them any planet or leave them white for the moon.

Here’s what you need to get started:

  • Baking Soda
  • Water
  • Measuring cup
  • Large Mixing Bowl
  • Tray for drying the rocks
  • Vinegar
  • Black or purple food coloring (optional – but colors make everything more fun!!)

img_8829

To make the planet:

Combine 2 cups of baking soda and 1/2 cup of water (add the desired color to the water) in a large bowl.  To make the the Jupiters, I split this into two bowls, one with red (looked orange) and one with yellow.

img_8750 img_8751

Then I mixed both together to get an orange-yellow swirly Jupiter look.  Kind of.

img_8752

Using your hands, take a handful and roll into a ball.  If it’s too dry, it won’t stay together, if it’s too watery, it will melt into a sloppy puddle.  Add water or more baking soda to adjust the consistency.  

img_8753

Let them dry overnight.  I placed mine in a plastic container and put them in the freezer to harden. 

The next morning, the planets were hard.    Note: this recipe will yield about 10 balls.

To explore:

I gave each little one a “Jupiter” and a cup with vinegar that had black food coloring and some silver glitter (“Starry Space Juice” is what I called it!).

img_8573

The tots definitely know what to do with the dropper and the vinegar.  Space juice was added to the planets for some fizzy fun!

Such an easy and simple little experiment to set up!

Science behind the Activity:

This is a twist on the classic baking soda and vinegar experiment.  Baking soda is a base and vinegar is an acid.  When combined, they release carbon dioxide gas (the bubbles).  The fizzing and bubbles are just way too much fun for the kiddos!

Galaxy in a Bottle

So this isn’t really a science experiment but I LOVE discovery bottles and this one is so pretty!  My older boys really enjoyed making this and it led to discussions about supernovas and galaxies and nebulae.  The tots in my class enjoyed the pretty swirly colors and filling the bottles.

Here’s what you need to get started:

  • cotton balls – almost a bag per bottle
  • empty bottles (I used old gatorade bottles)
  • paint in “galaxy colors” (we used metallic acrylic paint in purple, silver and blue)
  • glitter
  • straw (or something to push the cotton balls into the bottle)
  • cups

img_8240

First, create the colors of your galaxy by adding some paint to water.  We used metallic blue, metallic purple and metallic gray.  We love how swirly the water looked!

img_8241 img_8244

Next we stuffed our bottle about 1/2 full with cotton balls.  (It looks prettier if you shred the cotton balls, but my boys and the tiny tots don’y have the patience for that!)  We used a straw to help push the balls into the bottle.

img_8246

Next, add your first color to the bottle.

img_8247

Add some glitter.  (We probably should have added more)

img_8248

We noticed that as soon as the water was added, the cotton squished into a smaller layer.  So add lots of cotton! Like we did on the second layer.

img_8250

We again added a new color to the cotton.  And more glitter.  Make sure to push the cotton down as tight as you can.

img_8251 img_8253

We repeated it again with the last layer.

img_8257

Then we added the lid and shook it a bit.

img_8258

The puffy cotton looks like the “clouds” of space debris you see when you look at pictures of galaxies, nebulae, supernovas, etc… The glitter looks like stars in the night sky…

img_8264

While we were making these bottles, my boys asked me what a galaxy was and what a supernova was.  It was a great art activity to open up discussion about outer space.  While not a real science experiment, it sparked a science conversation.  It my book, that’s success!

Pie Plate Model of Earth’s Orbit

**Updated! 10/18/2016**

I have been meaning to to do a space themed lesson for a long time but was struggling to get some science activities (not just crafts) for the youngest set to do.  I finally “landed” on this one and it was fantastic fun and so easy to do!

Here’s what you need to get started:

  • Foil pie plates (must be round)
  • Black construction paper
  • Orange construction paper
  • Star stickers
  • Blue Marble (or blue-green, to represent Earth)
  • Glue
  • Scissors

img_8576

Since the tots in my class are pretty young, I measured out the bottom of the pie plates and cut out black circles for them.  I also cut out the orange circles to represent the sun.  For preschoolers and kindergarteners, I would definitely trace the circles for them but have them cut them out on their own.  For older kids, they can trace and cut on their own.

img_8263

Glue the large black circle to the inside of the plate.  This represents space.

img_8595

Next, glue the orange circle to the center of the plate.  This represents the sun.

img_8578

Place some stickers all over the black paper to represent the starts in the sky. As was noted by a fellow science teacher, there are no stars in our solar system except for the Sun.  To make this activity scientifically accurate, you might just want to skip the star stickers.

img_8596

Lastly, add the blue marble and spin the plate so that the marble spins around the edge of the plate, representing how the Earth spins around the sun.

img_8598

That’s it!  It’s a craft, but there’s plenty of learning (and fun) while spinning the plate.

The Science behind the Activity:

There are plenty of models of the solar system but I love how this is so simple for young kids to understand that the Earth is moving around the sun and not the other way around.  This same project could be done with the Earth in the center and a white marble to symbolize the moon spinning around the Earth.

To see where I got this simple but fantastic idea from, please visit: http://www.pinkstripeysocks.com/2015/05/preschool-science-solar-system-activity.html

*My only note on the original author’s post is that scientifically it’s not accurate to place 8 marbles in the pie dish to represent all 8 planets orbiting the sun.  The sizes of the orbits are very different and the planets would be showing that they are crashing into each other.  But her idea is great for showing one orbit at a time.*

**Updated: Skip the star stickers if you want to be scientifically accurate.  There are no stars in our solar system.  The only star in our solar system is our sun.**

Panning for Gold

So technically, this isn’t a *science* experiment/activity but it was part of my activities for St. Patrick’s Day where we went hunting for gold to put in our gold pots.  But it was so much fun for the tiny tots and for my superheroes that I had to share it:)  Super easy to do!

Here’s what you need to get started:

  • Bin or Sandbox (I use the shoebox size bins from the dollar store)
  • Sand (I used the play sand from Home Depot)
  • Gold (we painted rocks in our yard with metallic gold acrylic paint)
  • Plastic gold coins or pennies, plastic gems or shiny glass stones
  • “Tools”: sand toys such as sifters, shovels, rakes, magnifying glasses, etc…

IMG_5482

To prepare the rocks:

We first collected big and small rocks to make large gold pieces and small gold nuggets.  Then we painted them with gold acrylic paint.

IMG_1100_2 IMG_1104

We let them dry and they looked AWESOME!

IMG_1106

To prepare the box:

Fill the bin about halfway with sand.  Bury the gold rocks and gold coins into the sand.   Make sure all the treasures are covered up by the sand.

IMG_5483

Give your superheroes some “Tools” and let them dig and discover!  That’s it!  Easy!

IMG_5485The little ones enjoyed digging in their boxes for gold and treasures!

IMG_5486

This was definitely a favorite for my superheroes and the Tiny Tots in my science class.  I’ve also varied this with dinosaur eggs and skeletons in my Dinosaur Dig activity

 The Science behind the Activity:

Here is another science activity that invites young children to explore, investigate and be curious, just like real scientists.  They choose which tools to use and how to use them and what methods are best for locating the hidden items, and cleaning off their finds.  Lots of problem-solving and the kids think that they are just playing in the sand!

Extension:

This activity can be modified for any hidden items.  You could also throw in some gems, large beads,  Great for a pirate party or to link to a history unit.  You can also add magnetic items and non magnetic items and have them use a magnetic wand to find and test the items!  So many options!

Why Does an Octopus Have Ink?

Whenever I visit the Aquarium, I always fall in love with the jellyfish and the octopi.  Watching an octopus move is just so mesmerizing!  They are also known to be very intelligent creatures.  And like most squid, they have an ink sac (which is so very cool if you have ever dissected a squid).   In this quick, simple, activity, your superheroes are going to observe and explore why squid have an ink sac.

Here’s what you need to get started:

  • water
  • 1 clear glass
  • 1 small cup
  • black food color/watercolor/paint
  • dropper (I always save the ones I get from the pharmacist!)
  • small plastic octopus toy
  • small plastic shark (optional)

IMG_5315

In the small cup, mix some water with black paint/food coloring or water color.  I had none of those so I mixed red and blue food coloring to make a dark purple.  This will be the “ink”

Fill a clear glass halfway with water.  Add the plastic octopus to the water.

IMG_5316

Discuss how the octopus looks in the water.

Using the toy shark, I showed my son that a predator was approaching the octopus.  What was the shark going to do?  What could the octopus do to protect itself?

IMG_5317

Using the dropper, add “ink” to the glass with the octopus.  This models that the octopus will release dark ink as a defense mechanism.  What happens to the water as the ink is added?  Can you see the octopus?

IMG_5318 IMG_5319

After some discussion, my son decided to play with the shark and the octopus and ink.  It kept him busy for awhile as he engaged in pretend play and the narrative he added was so cute to listen to.

IMG_5321

Extension: Try this in a large shallow dish by adding the shark and the octopus.  Add the ink just on top of the octopus.  What happens to the ink?  Can squirting ink alone help the octopus protect itself?  What other defense mechanisms might they need to help protect them from predators?

The Science behind the Activity:

This little activity is a simple model of how an octopus, like most squid (but not all squid) use an ink sac as a form of a secondary defense mechanism.  By squirting the ink, the predator gets confused AND the ink often has a smell associated with it that also deters predators.  With the smell and the spray shocking the predator, it allows the octopus to use its quick tentacles to escape before the ink dissipates.
