Numeracy across the Curriculum Numeracy in Science

The Purpose of Station Activities • Learning Stations help students gain confidence and build self-esteem and encourage the shy ones to ask questions and discuss their answers. • Learning Stations allow students to work independently and in small groups. • Learning stations allow students develop time management skills. • Learning Stations help students develop problem-solving skills. • Learning Stations help build peer cooperation and peer support. • Learning stations reinforce “classroom skills”, such as taking turns, etc. • Learning Stations make learning and teaching FUN!!. Learning stations engage all students and minimise behavioural problems.

Station 2 Station 1 Station 3 Station 4

Station 1 Range of hearing - Graphs and tables

A- Refer the graph below to answer the following questions: 1 - Identify which animal can hear the highest frequency sound. 2 - Identify which animal /animals can hear the lowest frequency sound 3 - State whether a chicken can hear any of the sounds heard by a bat.

B- Use the following graph to create a table to show frequency of hearing for each animal.

Station 2 Scientific notation

1 - State the following in Scientific Notation: A- 470 000 B- 0. 0006 C- 21 000 000 D- 0. 000 000 009 2 - State the speed of light in different media in scientific notation

Station 3 Wavelength

Question 1 What is the speed of a water wave that has a frequency of 0. 5 Hz and a wavelength of 3 m? Question 2 What is the wavelength of a radio wave transmitting at 98. 3 MHz? Question 3 Two waves on identical strings have frequencies in a ratio of 2 to 1. If their wave speeds are the same, then how do their wavelengths compare? a. 2: 1 b. 1: 2 c. 4: 1 d. 1: 4 Question 4 Dawn and Aram have stretched a slinky between them and begin experimenting with waves. As the frequency of the waves is doubled, a. the wavelength is halved and the speed remains constant b. the wavelength remains constant and the speed is doubled c. both the wavelength and the speed are halved. d. both the wavelength and the speed remain constant

Station 4 What is the frequency?

S=f× λ Speed=frequency × wavelength
