Over the last few weeks we conducted scientific experiments and wrote them up in lab report format. This week we continue to conduct science experiments, such as what happens when various liquids (fabric softener, colored water, dish detergent, and oil) are mixed with water. This time, we are documenting our experiments on the iPads using an app called 30 Hands. Students take photos and upload them into their presentations, then record themselves explaining what they observed. The green boxes are sound boxes that allow students to record their voices without outside noise filtering in.

We spent time exploring solids that come in small pieces, such as beans, rice, corn meal, rock salt.
Each partnership was responsible for conducting a series of investigations of one solid. What happened when you poured it from one container to another? What happened when you put one scoop of it in various size containers? If you put some in a bottle and some in a small vial and shook both, what was the difference in the sound?
Students took careful notes of their findings. Tomorrow they will make posters to share what they learned about their solid with the rest of the class.
An extension of our science unit on solids and liquids and our mini-unit on science writing. I posed the question, "What solid materials are the best for building a tower?" The class brainstormed a list of solid objects in our classroom.
Each student then came up with a hypothesis about which objects (no more than 5) would be best.
Next, we built towers and measured them.
Students then wrote a procedure: step-by-step instructions for building their towers.
Then, results: How tall was your tower? Did it fall down?
Last, conclusions: Looking at your tower versus other students' towers, what did you learn about which materials are best for building a tower? What would you do differently next time?
Lots of fun and good scientific thinking!
