Stage 1: What is Going into the Bin?
Student can explain the difference between biodegradable and non-biodegradable. They calculate how much rubbish bags all their families together produce each week and then calculate how much rubbish their families produce during the...
Curated OER
Protoplast Production (Plant Cells Without Walls)
Students explore the spherical protoplasts of plants. Students observe that plant cells have a plasma membrane in addition to the cell wall. Students plasma membranes, solutes and organelles.
Curated OER
Vectors
Young scholars describe motion by the use of adding vectors. They identify the difference between the x and y components of vector quantities. Students are given the Paper Bridge Building handout and the instructions as to where to...
Curated OER
A Botanists View
Young scholars explore plant and seed structure. They dissect a seed and identify its parts. In addition, they explain the function and compare and contrast monocotyledon and dicotlyledons.
