# CSIRO “Science of Sport”

Following the “Toy Science” workshops, Simon from CSIRO presented four “Science of Sport” workshops for students in Grade 6 to year 9. Students were given the opportunity to learn about:

• how shape affects drag force,
• test their heart rates before and after exercise,
• test the amount of glucose in different drinks,
• dissect a chicken wing to show muscular movements,
• test their reaction times,
• test how different materials absorb simulated sweat,
• demonstrate the friction forces on sport shoes on different surfaces and
• test their ball throw speeds.

Students rated the presenter 3.5 to 4/5; the activites 4/5 and the topic 4.5/5.

# The Science of Toys with the CSIRO

Students working out how different size frogs make different sounds.

Today we welcomed Simon from the CSIRO “Labs on legs” program to the school for National Science Week. He presented two workshops to prep to year 5 students about the science behind how toys work. Students learnt about:

• what is inside a baby doll,
• how to make a slinky ‘walk’,
• which spinning tops work best,
• how a ‘magna-doodle’ works,
• what is inside a kaleidoscope,
• how to make a toy car do two 360 degree loops,
• how to measure the speed of a toy car
• why different size frogs make different sounds and much more……………
