Build and decorate your submarine model.
Ages 8 - 12+
Learning outcome: Maritime and sea exploration are highly important for transportation of goods and people. Learn how ships can float over water due to buoyancy. Understand what is density, how it varies over objects and comprehend that density is a significant factor which determines whether an object will sink or float on a fluid.
Experiment Method Description: Build and decorate your submarine model. Use a sink filled with water to tests its buoyant behavior. Alter its density using a combination of materials such us air, water and investigate whether it will float or sink.
Components: Engino parts, plastic skins and paper outlines, sink with water, plastic bottle, pebbles.
Scientists invented the "photovoltaic" panels which can convert sunlight to electricity and can power up our machines with free and clean energy.
Ages 8 - 12+
Learning outcome: Our Sun provides so much energy to our planet that if we were to harness it efficiently all pollution and global warming problems would had been solved! Scientists invented the "photovoltaic" panels which can convert sunlight to electricity and can power up our machines with free and clean energy.
Experiment Method Description: Test how the area of a solar panel affects its overall efficiency. Observe the number of rotations in one minute when the solar panel is exposed under direct sunlight. Partially cover the panel’s surface and measure once again the number of rotations. Prove that the produced electricity increases when the collecting area of a panel gets larger.
Components: Solar blade, Engino parts, plastic skins and paper outlines, adhesive tape, piece of carton, sunlight.
