    Hi Mrs. Yates! What we did today was the yeast investigation. My favorite part was my part (writing on the bags and bringing bags to our table). I wonder what we are going to do tomorrow?

    I learned that yeast was a living organism. I think that the salt or sugar and water will make yeast break it's dormancy.

  13. I loved the experiment today. I think it was so cool! My hypothesis was wrong because the sugar just dissolved in the yeast and water.

    My hypothesis for today's work was that my hypothesis is that i think that the bag with water,yeast, and sugar will activate more than the water,yeast and flour bag. I hope my hypothesis is supported. ><
