Properties of Slime

Everyone put their little bits of slime together for activities at the sensory table.  If  the slime gets a little too sticky, a squirt of water or liquid laundry starch seems to help.

The students discovered that slime has some interesting properties. Slime can be broken into pieces if you pull on it with a firm grip. Allow the slime to stretch itself by hanging and it seems to stretch endlessly.

How long would it stretch? We don’t know yet, but that is another lesson for when the teacher remembers to bring some wax paper. There is not enough space on the Discovery Table to stretch slime to its limits.

Slime Is Fun!

Circletime for this theme starts by learning a new song:

Wiggle Worm
(Tune: Twinkle Twinkle Little Star)
Wiggle, wiggle little worm (lace fingers and wiggle them like worms)
Through the grass and dirt you squirm.
You don’t like the light or sun’ (hide eyes)
But you think the mud is fun. (rub hands together)
Wiggle, wiggle little worm (lace fingers and wiggle them like worms)
You are slippery when you squirm!

Earthworms are very different from the critters we encounter above the ground. They do not have eyes, ears, legs, arms or even lungs. Worms breathe through their skin. Their skin must stay wet so the oxygen can pass through. They cannot breathe underwater, though, so life underground can be tricky. Earthworms are very slippery. This is because of the thin layer of slime that covers their body and helps them to stay moist.

We made slime in the classroom. I put green coloring and liquid laundry starch into two different small spray bottles. Squirt one teaspoon of white school glue into a child’s hand and ask them to stir it with a finger on their other hand. One squirt of green and three or four squirts of starch and things start to get slimy!

The small balls of slime can be combined and kept as a tray activity for the sensory table. Add a few plastic bugs for the goo factor!

If things seem a little sticky, add a few more squirts of the starch. Slime will stick to hair and clothes, but washes out with water.

Have fun!

Light Up the Earthworm’s World

The light table’s theme has changed this month to help the students imagine where an earthworm goes underground.  I used construction paper and yarn to create an underground view of a worm’s world. The worms are made from heavy yarn.  Dip the ends in white glue and allow to dry to keep them from unraveling.

This will lead to another chance to talk to a student and take dictation about thoughts on what a worm does while underground.

Theme for September: Earthworms

Most people say “EWWW” when I mention earthworms. Sometimes a small critter that grosses out  some people  is very important to us!  They play an intricate part of our circle of life. Worms eat old dead stuff. They help us recycle newspaper and leaves back into the soil. Plants benefit not only in the rich soil, but also in the aeration of the earth as the worms tunnel about. They soften the earth and this allows the rain to penetrate and easier growth of the plants. A great place to start learning about the earthworm is The Adventures of Herman.

Our first project is making a Worm Farm.

Worm Farm
The students help spray shredded newspaper with water and tear it into smaller pieces to make the bedding.

Worms that hatched out in last year’s Farm are on display.

 

Tomorrow we will add earthworms! They can be purchased from local stores that have a sports or bait section.

Space in a Bottle

Discovery Bottles are a great way to enhance sensory process while helping to focus on a few scientific facts.  Two bottles in the science area this month have water, glitter pom pom balls, Make it Glitter, and black and blue coloring.  Take care to use very little black coloring, it gets dark fast!  Shaking the bottles is just plain fun.  The glitter pom pom balls hold up well in liquid and float around when the bottles are moved.

 

Space Discovery Bottles

While watching the swirling motion in the bottles questions about day and night, planets, and space lead to dictation and artwork later in the day.  OR  just have fun!
