Diggin’ Dinos

We have been digging for dinosaur b0nes this week.  The dinosaur dig kits are are blocks of sand around 7 pieces for of a dinosaur.  The head, arms, legs, tail and body. The sand is firm so it is taking a while to dig the pieces out.  The kids love it!  We will work on it more next week.  Great lesson on dinosaurs, paleontologists, patience and fine motor practice.

When I win the lottery

Here are some cool science items that I would buy if I won the lottery.

Ant farm!!!!

So if I do win the lottery I am gonna have some really fun toys!  I might even share them with the kids…….maybe

Catapults!

I made three different catapults.  We will test them and see which one works the best.  I have been testing them out with cat toys.

Image

The last one is made with a clothespin and a popsicle stick.  This one is easy to make and works very well.

More sensory cards

Sensory bottles

Here are the first of many sensory bottles that I have made.  Image

The green jar has water, oil and buttons. Some of the buttons float on the oil and some sink.  If you shake up the bottle you can watch the layers seperate out again.

Image

The orange bottle has wood, plastic and glass beads.  Again it is a sink and float bottle.

Image

The green and white bottle has water, green coloring and soap bubbles.  It is fun to see the green water turn into white bubbles. I got the coloring from an old green marker that had dried out.

Image

The next is a glitter and sequin bottle.

Image

Then we have a magnet bottle with short pieces of pipe cleaner.

Image

The last one is a jelly fish bottle.  I had a hard time taking a picture of it. It is a small piece of plastic that is tied so that there is a small bubble on top and long tenticles.  When you turn the bottle over the jelly fish floats.

Image

I got the idea from this site. http://bhoomplay.wordpress.com/2011/09/09/diy_jellyfish_eng/

Sensory bags

I made these bags from a variety of materials that were around the house. Image

The fabric is from an old pair of pants. The crinkly bag has the plastic from a water bottle label, the bumpy bag had large beads, the squishy bag has cornstarch and water in a plastic bag (double bagged) the round has a bottle cap, heavy will have sand the the light will have nothing in it, the hard will have a piece of wood in it and the soft has little pieces of left over fabric.

Image

Each bag has a match without any label on it.  Older children could match the bag with the word.  Children who are writing could write a short sentence using the adjective.  Ex. The mud is squishy.

What other things do they know that are squishy?  What other textures could be used for this activity.

Ball launcher

Here is a ball launcher for launching cat toys.  You can have your kids launch balls of different sizes and weights to see which one goes the farthest.

Image

The smaller tube has packing tape on the end.  The larger tube has slits in the top and the rubber band is wrapped around it on one side.

Image

The smaller tube has slits cut in the bottom for the rubber band.

Image

Then slide the tubes together, insert a ball and launch!
