2024 Science Showcase K-4 Videos

The Toronto Science Fair invited teachers of Kindergarten to Grade 4 to organize class science projects or small group science projects during the winter term.  They were then invited to have students make a one-minute video to record what they investigated and what they discovered.  Many teachers and students took up this challenge and submitted their videos to the Toronto Science Fair Science Showcase.   Follow the links below to view their discoveries.

This is a showcase of science at the Kindergarten, Primary and Junior level not a competition.   TSF hopes that this experience will encourage our younger students to continue to investigate scientific questions.

Kindergarten to Grade 2

5 Senses Experiment - Fieldstone Day School - Kindergarten.mp4

5 Senses Experiment

Fieldstone Day School
The Kindergarten class used their knowledge of the 5 senses to complete this experiment. The students had to use their touch and smell senses to guess objects that were put into a box covered by a garbage bag. They could not see the objects at all, and relied on their senses to help figure out the hidden object. After feeling the objects, the students then had to return to their desk, and write the name of object draw a picture of the object they believed to be in the box on their worksheet. At the end of the experiment, the objects were revealed to the class, and the students could see if their predictions were correct.

LÉquilibre est la Clé de la vie - St. Bonaventure CS - Grade 4.mp4

L’équilibre est la clé de la vie

St. Bonaventure CS
Dans notre corps, les cellules sont entourées d’une structure appelée membrane cellulaire. Cette membrane est semi-perméable, ce qui signifie que seules l’eau et de très petites molécules peuvent la traverser. En utilisant un concombre comme une membrane semi-perméable, du sel comme un soluté, et de l’eau distillée comme un solvant, on peut observer le phénomène d’osmose. Pour maintenir l’équilibre, l’osmose permet d’égaliser des concentrations entre l’intérieur et l’extérieur d’une membrane cellulaire. C’est le passage de l’eau entre deux zones qui permet aux plantes et aux animaux de maintenir l’équilibre de leurs niveaux d’eau et de nutriments.
Organic Plastics from Different Milks - St. Dominic Savio - Grade 4.mp4

Organic Plastic from Different Milks

St. Dominic Savio Catholic School
Which milk will produce the strongest organic plastic?  I though that 2 % milk would produce the strongest plastic when experimenting with 2 %, 3.25 % and soy milk.  I made plastic by mixing milk and vinegar, heating it up and then drying it out.  I found that soy milk was unable to make casein plastic, there were curds and it was soft and mushy.  I tested the two other plastics using a drop test and a weight test.  I found that the casein plastic from the 2 % milk was the strongest plastic.

Weathering and Erosion - Bayview Glen - Grade 4.mp4

Weathering and Erosion

Bayview Glen
The investigation consist of combining a sugar cube and small rock together in a small container, then shaking them 50, 100 (and so on) times in order to observe the effect of the friction and impacts between the two objects. As they shake the container more and more, students will observe that the sugar cube, simulating a soft rock, will gradually have its edges worn away and become smoother and more rounded. Eventually, it will weather away entirely into its individual component grains, mirroring the effect of weathering on rocks and minerals in the real world.
