My science expo project was a blind taste test.  For my experiment I used Coke, Faygo cola, and pepsi as my variables.  The temperature of the drinks and the type of cup are my control variables. For the Experiment I gave people three cups labeled A, B, and C.  Drink A was Coca-Cola, drink B was Pepsi, and drink C was Faygo cola. I asked people what they normally like to drink. Then I had them try all three and pick their favorite letter drink.    Three people said Coke was their favorite drink but chose Pepsi in the experiment. Two people said Coke was their favorite drink and chose Coke in the experiment. One person said Pepsi was their favorite drink but chose Faygo cola in the experiment. Another person said Pepsi was their favorite drink but chose Coke in the experiment.

1. Would people choose differently if they were displayed differently
2. Would people choose differently if they were different temperatures
3. what would happen if they were different colors?

  

      This week in science we started learning about the nervous system. We did an experiment that was fun but it was really scary. It was scary because I hate needles. We had to put on a blindfold and poke each other in different places with needles. Some needles were closer together and some were farther apart. There was one with only one needle. We got to see which areas had better sense of touch. I did pretty good. I got most of them right.  We guessed all of them right on the back of our hand. I wonder why that is. Does gender affect our nerves? Why do some people feel more things than others. ( I don’t have pictures of this project. )

The past two weeks we have had multi age classes about trash. In science Lizzie and I are learning about food waste.  This unit made me think a lot.  Some of the things I learned really bothered me. I had no clue that 40% of food is thrown out.  That’s a 162 billion dollars in waste. We made a canva filled with crazy other facts. I wonder if people are unaware that food waste is an issue. We also learned about 0 waste. There are some people make there own cosmetic products to avoid creating trash.  I wonder what got them so so motivated. people who do 0 waste  buy a small amount of clothes. they take reusable bags every where. They basically can’t eat processed food either.  I wonder how many people do zero waste. I would love to talk to them and here about there

          This week we started talking about drugs. I made a google slide about GHB.  I read different scary stories about the drug and how careful you have to be with where you get  your drinks.

This week we made bridges.  We had a limited amount of toothpicks and hot glue.  The bridge had to be flat enough for “cars” to go over.  Then we made the bridge over a  “river”. Our main goal was to make it sturdy. on monday we are going to add wait to our bridge and see what it can hold.  Last week, I was in Florida and I saw a lot of bridges that I was able to think about when I made my bridge.

One of the things we did was make lots of triangles.  I did get frustrated sometimes, but I think Andre and I worked well together.  Our bridge was very strong. I wonder how the toothpicks were able to combine and become so sturdy. I’m excited to see how much weight it will hold.  I wonder how sturdy it would be if we used less hot glue. If we made a bigger bridge would we have to make it thicker.
