Day 35 ~ Tornado Exploration
A couple weeks ago there was a storm in the middle of the night, and the tornado sirens went off where the girls live. They told Abram all about it, and this sparked much curiosity about tornadoes. Abram’s incessant questions finally drove me to the library where we found a few books and videos about tornadoes: Tornadoes! by Gail Gibbons; Inside Tornadoes by Mary Kay Carson; Otis and the Tornado by Loren Long; “Twisters! Nature’s Fury” (VHS); “Tornado Intercept” (Netflix).
Even though we spent the whole weekend exploring “the world’s most violent storm,” the girls wanted to read the books when they arrived on Monday morning. So we did. Then we rounded out our exploration with “Tornado in a Jar.” When the local sirens went off during lunch time, there were some very nervous children about! I had to explain repeatedly that it was just a test. Whew!
Reading about Tornadoes
- Fill a jar 3/4 full of water
- Add 1 tsp. clear liquid soap, 1 tsp. vinegar, a couple drops of food coloring, and some glitter (food coloring and glitter optional).
- Close the lid and shake jar to incorporate ingredients.
- Swirl jar in a circular motion–the liquid will form a tornado!
We used large jars, so we doubled the amount of soap and vinegar. Glitter is a nice touch, as it shows what debris looks like in a tornado. After the contents were well-incorporated and there was a nice foam on top, we added a few more drops of food coloring in a contrasting color (i.e., green added to red). Instead of shaking the second round of food coloring in, we swirled the jar. This made the tornado much more visible!
Day 36 ~ Letter R & Rain
In keeping with the weather motif for the week, we decided to explore rain for the letter R. After we talked about the letter R and practiced writing R (and other things) on our whiteboards, we discussed how rain forms and drew “The Cycle of Rain” posters. Then we made “Rain in a Glass.”
Writing letter R… and other things
Rain in a Glass
- Put a small amount of hot water into a glass.
- Cover the top of the glass with foil, and push the foil into the glass to form a “dish” to hold the ice cubes.
- Place a few ice cubes in the foil dish.
The warm water in the glass evaporates, turning into water vapor. The water vapor rises to the top of the glass, where it hits the cold foil. It clings–or condenses–onto the foil, forming little droplets of water. When the water droplets get very heavy, they finally fall–PLOP! Back into the water.
