The children had a great time searching for shells. When the theme was over I had the children search for all the shells and place them in a tub of warm soapy water and toothbrushes, where they helped me clean up the shells to be put away.
Diving Fish – I take a clear 2-liter bottle and draw (with perm. markers) on the outside (seaweed, waves, etc) I then fill the bottle with cold water. Add 1/4 cup white vinegar and 1 T. baking soda to the bottle. It is then time to add the “fish” . Drop about a dozen raisins into the bottle and be ready to watch! The raisins will collect bubbles all around them from the vinegar and baking soda chemical reaction – so they will FLOAT to the top, the air bubbles will pop and they will sink back down to get more bubbles. It is great! My class thinks that this is a real magic trick! It will last for about 20 minutes or so, maybe longer.
We had a day where we focused on octopuses. We read books on octopuses and then we made an octopus using purple construction paper. I precut figure eight shapes (for body of octopus-older students could cut it themselves). I then cut out eight strips of paper (1×4 inches). The children counted out how many tentacles an octopus has and then chose that many strips of paper. They glued the strips to the bottom of the body and then colored a face on the opposite side. It looked cute and the kids had a lot of imaginative play with them.
My two-year-olds loved this- For beach week we each brought in clear 12 oz. bottles. We added sand, a small bit of water and small sea shells. Our kids love to turn these on their side and watch the ocean waves. We glued on the lids then taped them with colored tape.
Plastic Bag Jellyfish
Here’s a way to demonstrate a jellyfish to your class. Supplies needed: 2 clear plastic bags (no Ziplocs) any size, food coloring, rubber band or twist tie.
Fill one plastic bag about 1/2 full with water and add a little food coloring. The colored water is the jelly, the bag is the skin. Open the bag and carefully put the 2nd bag inside the 1st…this is the stomach. Add a little water inside this bag to help it hold its shape. Now, draw the mouths of the bags together and put the rubber band on tightly. (The 2 skins of a jellyfish meet at the lips, and this is the only opening to the body.) Grab bags at the rubber band and turn them over, resting the weight on your hand. Now you have an example of a jellyfish with short mouth arms, but no tentacles. You can let the children hold it carefully to feel what it’s like. It feels very much like a jellyfish. You can also put it in a bowl of water and watch it float.
My kids absolutely love it!!
