This week in first grade reading, we set out to do some tests to help determine exactly what happened to Danny, the pilfered hippopotamus. The cloffice was divided into five stations, and the kids rotated among the stations to perform the tests.
The next station was the Juice Test station. The juice found at the scene seemed a little suspicious. Had something been added to it? The children used Ph paper to test the acidity of the juice. They dipped a strip of paper in the juice, knowing that if the paper turned green, it meant that some kind of powder had been put in the juice, but if it stayed yellow, nothing had been added to the juice.
At the Fingerprints station, the kids looked at a picture of the cup found at the scene. Three fingerprints were found on the cup. The kids matched the fingerprints to their owners, using a chart of the fingerprints of the five club members.
At the next station, we examined three types of thread — cotton thread, wool thread, and the mystery threads found at the scene of the crime. Were the mystery threads smoother and tighter, like the cotton threads? Or were they wiry and loose, like the wool thread? Who was wearing cotton and who was wearing wool?
At the Footprints station, the kids examined the footprints left at the scene and compared them to the footprints of the five club members to determine who had made the tracks found at the scene.
Finally, there was the Smells station. When Danny was found at the scene of the crime, he had a distinctive smell. Brandon and Julia had both just washed their hair. Did Danny smell like their shampoo? And if so, which one? The kids endeavored to find out.
First, the students smelled Danny. Then, they smelled Brandon’s shampoo, and then Julia’s shampoo. The kids decided which smell they thought matched Danny, and they recorded this information on their data sheets.
Ask your child about the results! Do the clues point to a particular club member as the culprit? Or does it seem like more than one person looks guilty? After we finished the five stations, the kids met to discuss their results.
Next week, I will be out on Thursday, in Orlando and the National Association for Gifted Children Conference. The following week, we will have Crime Lab Part Two, and thereafter we will solve the mystery.
There is no homework this week!
