On Friday October the 21st.
We had a worm experiment we were all in a group of five or four. We were given two cups each one massive one and one small and then our teacher miss Clark put in some water. We put calcium chloride in the water that activates our worm project. When our big cup was added with the calcium chloride we got 3 Pipettes each. Then came our small cup our teacher poured some sodium alginate in the colour was red after a about 5 seconds later we got out Pipettes and suck up some of the sodium alginate and put it inside the big cup. Then it turned into a blue and yellow colour.
