Perform activities that allow you to explore the solid and liquid phases of matter. Set out ice cubes and different items to melt them; sand, salt, kitty litter and sugar, for example. Make predictions about which item will melt the ice into water the quickest. Set ice cubes into individual bowls and sprinkle a bit of each substance on top of a different cube. Time how fast the ice melts. Which material melted the ice the quickest? What material was the slowest ice melt? How did they compare to letting ice cubes melt with no assistance?
This science investigation will likely help you remember to put on sunscreen. Run a piece of tape down the center of a piece of black or dark blue construction paper. On one side of the tape, rub an SPF 30 sunscreen onto the paper and leave the other side untouched. Set the paper out in the sun for a period of 30 minutes. After the 30 minutes is up, examine the paper and observe what happened. The side of the paper that was left unprotected should have become lighter, while the side with the sunscreen on it should remain the original color.
Examine the power of static electricity with this investigation. Blow up a balloon, tie a string around it and suspend it from the ceiling. Blow up another balloon and rub it against a piece of wool. Hold the balloon that has been rubbed against the wool near the balloon that is hanging from the ceiling. The balloon that has been rubbed against the wool has been charged with static electricity, which will cause the other balloon, which has not been charged, to move away from the charged balloon.
Through this investigation, you'll gain an understanding of how the sense of smell effects the sense of taste. Set out items that have a mild, yet distinctive taste; cheese, apples, potatoes and popcorn, for example. Close your eyes and taste each of the items and then close your eyes, hold your nose and taste each of the items. Note if you were able to identify the items based on their taste with your nose plugged or not plugged. With your nose closed, it was likely difficult to tell which item was which, as the sense of smell has a great impact on the sense of taste.
