2/12 Lets make ice cream

last Thursday we made ice cream in science. I was in a group with three people Naomi,  Maddy, and I. First, we watched video about endothermic and exothermic. Endothermic is when heat/coldness gets taken out of something and sucked into something else. Exothermic is when heat/coldness gets sucked out of something and into another thing. they are just opposites. Then Shane gave us the instruction sheet it was:

1. Add milk and sugar to a quart-size bag. Seal securely and put inside the other quart size bag. 

2. Put a pitcher full of snow into a gallon size bag.

3. Take the temperature of the snow in the bag.

4. Add the salt to the bag of snow.

5. Place the DOUBLE BAGGED sealed bag of milk into the gallon bag of snow.

6. Gently rock the gallon bag back and forth for 10-15 minutes or until the contents of the small bag has solidified or go outside with gloves on GENTLY toss the bag back and forth. 

7. Open the gallon bag and use the thermometer to measure and record the temperature of the ice/salt mixture. 




over the past couple of weeks, my class has been doing a murder mystery thing in science. I have not been here due to being in Florida, so I was a little confused about what we were doing. But basically there was a bag of fibers for every character (made up for the murder mystery). We burned each fiber over a candle to see how each fiber reacts to the fire. We also used a microscope to look at the fibers up close. Carry okey was the coolest one in my opinion. We drew the fibers then wrote about them, then the cases ended.
