CASE: Find and save the legendary Odd Artifact - the 44 - leaf cover
OUTCOME: We unlocked a secret chest to find the map to the 44-leaf clover. We used Omar’s souvenir to measure the right rectangle that opened up the chest and then used a fulcrum and lever to get by the huge tape wall that was blocking the exit!
COLD CASE EXTENSION ACTIVITY:
Something VERY ODD has happened! Rulers are walking and talking and their numbers are scrambled! In order to make them go back to normal, you must:
1. Find 1 object that is the same size as your favourite stuffed animal.
2. Find 1 object that is the length of TWO of your stuffed animal.
3. Find 1 object that is HALF the size of your favourite stuffed animals.
4. See if you have a ruler in your house and measure the length of your favourite stuffed animal and all 3 items that found!
TIP: Record your findings in a chart like this!
OBJECT
LENGTH IN CENTIMETERS
Favourite Stuffed Animal
Object 1: __________
Object 2: __________
Object 3: __________
SYNOPSIS FOR TEACHERS/PARENTS:
In this episode Agent Opal and Agent Omar go on a mission to find and save the legendary Odd Artifact-a 44-leaf clover. During their mission they encounter several obstacles that require them to 1) use measurement skills and measurement tools and 2) use simple machines such as pulleys, to achieve their mission.
This episode teaches children how they can use conventional measurement tools, such as rulers, to measure items, and also unconventional measurement tools, such as objects, to measure different things. It also introduces children to the effectiveness of using simple machines.
CURRICULUM EXPECTATIONS:
Grade 2 Science - Understanding Structures and Mechanisms: Movement
1.1 Assess the impact on society and the environment of simple machines that allow movement (e.g. common mechanisms and simple machines make it easier to carry out tasks that require movement because less force is needed)
2.3 Investigate the structure and functions of simple machines
3.3 Identify the six basic types of simple machines - lever, inclined plane, pulley, wheel and axle - and give examples of ways in which each is used in daily life to make tasks easier
3.4 Describe how each type of simple machine allows humans to move objects with less force than otherwise would be needed
Grade 1 Mathematics - Measurement
Demonstrate an understanding of the use of non-standard units of the same size for measuring
Construct, using a variety of strategies tools for measuring length, heights, and distances in non-standard units
Compare two or three objects using measurable attributes and describe the objects using relative terms
Compare and order objects by their linear measurements, using the same non-standard unit
Grade 2 Mathematics - Measurement
Estimate and measure length, height and distance, using standard units and non-standard units
Select and justify the choice of a standard unit (i.e. centimetre or metre) or a non-standard unit to measure length
Compare and order a collection of objects by mass and/or capacity, using non-standard units
Grade 3 Mathematics - Measurement
Estimate, measure, and record length, height, and distance, using standard units
Estimate, measure, and record the capacity of containers, using the standard unit of the litre or parts of a litre
Compare and order objects on the basis of linear measurements in centimetres and/or metres in problem solving contexts
