As part of our science learning on properties of solids, liquids and gases, we are learning about floating and sinking. Since, Our discovery tubs were a huge hit in grade one last year, I decided to introduce some new ideas with discovery sessions this week. Students found this type of learning very engaging and enjoyable and I am impressed with the learning, observing and questioning taking place. I felt that it was appropriate at the Grade 2 level to have students record some of their thinking, so as good scientists, each of my students is keeping a recording sheet of observations, materials, questions and ideas. I put together two "types" of tubs: object tubs and construction tubs. Each station had an additional water tub and a towel! Read below to find out what our discovery tubs included this week!
Discovery Tub Contents:
Construction Tubs - these tubs encouraged learners to construct/build something from smaller parts.
Tub 1
masking tape
popsicle sticks
plastic bottles (from recycling)
wooden rulers
clay
Tub 2
wooden blocks
plastic blocks
masking tape
Tub 3
aluminum pop cans (from recycling)
egg cartons (also recycled)
paper and cardboard (recycled)
masking tape
Discovery Tub Contents:
Object Tubs - these tubs encouraged learners to find out which individual objects would float or sink. I used a variety of objects from around our classroom to fill each tub. Tub 1:
plastic cutlery
foam dice
plastic dice
plastic pieces
foam pattern blocks
wood pattern blocks
wooden blocks
plastic people manipulatives
coins
markers
foam dominoes
sponges
Tub 2:
egg cartons
plastic blocks
plastic fish manipulatives
dinosaur manipulatives
lego blocks
plastic mouse manipulatives
erasers
paper clips
popsicle sticks
