(math & science for primary grades)

Activity and Lesson plan

Original by Juli Schroeder and Mary Beth Sukup

*Contents Overview*

## Overview

A plan to facilitate a review and develop a deeper understanding of observable properties and how to measure their change to make better decisions when critically thinking.

This sequence introduces students to both standard and metric measurement. They will learn the standard units used to measure length, weight, fluid volume, and temperature. Also, how to use the appropriate tools in different situations to measure how objects change.

*Background information*:

This plan is designed for students who have the following *prior knowledge*:

*Related study topics*:

## Big ideas, concepts, facts, and outcomes

### Big ideas

### Related concepts and facts

- Better decisions are made when information is verified before being considered accurate and used to reason and develop explanations and models to understand the world and make decisions.
- People make better decision when they understand and consider the positive and negative influences that effect their decision making.

### Outcome

Determine an appropriate manner to collect measurements, which are accurate for the task and decisions they are making.

### Processes, Inquiry, & cross cutting skills to enhance science literacy

* * *Big ideas*: Properties of objects are determined by the elements from which they are made. Properties can remain constant, change, and be measured. They are used to identify objects, as variables in experiments, operational definitions, and explanations. Properties of matter include: color, texture, size, shape, mass, volume, density, temperature, chemical, energy, states of matter (solid, liquid, gas, plasma) and the ability to interact with other objects. Properties are identified with observation and can be measured with scientific tools and compared to a standard unit (linear, time, temperature, mass, volume, and density)

### Related concepts and facts

- Linear measurement is the measurement between two points.
- Linear measurement standard units are cm, m, km, inch, foot, yard, and mile.
- A meter tape can be used for linear measurement.
- Temperature measures hot and cold.
- A thermometer is used to measure temperature.
- Degrees in Celsius and Fahrenheit are standard units of temperature.
- A thermometer goes up when the temp goes up, if the temperature goes down, the thermometer goes down.
- Volume standard units are ml, liter, pint, quart, and gallon. Volume measures the space an object occupies.
- Mass standard units are g, kg, pounds, ounces, and tons.
- Mass is the measure of how much matter is in an object or system.
- Measurements can be compared.

### Outcome

- Determine an appropriate manner to collect measurements, which are accurate for the task and decisions they are making.

### Perspectives -

*Big ideas:* Science and mathematics can help us solve everyday problems.

### Related concepts and facts

- Measurement helps us to understand change.
- Measurement helps us communicate more accurately.
- Measurement helps us make tools and other objects.

### Outcome

- Explain how measurement is an important process for science, math, and everyday life.

## Lesson Plans

### Activity 1 - The First Straw

*Materials*:

- How Long Is It - lab sheet/student,
- Meter tape, 100-cm/student or group,
- Enough straws of
*different*lengths (can cut straws to different lengths) so each student has one, - Transparent tape,
- Scissors,
- Crayons/colored marking pens

*Focus questions*:

- How big is your table?
- How do you tell others the size of the table?
- If we wanted to see if it fit in a space, without moving it, how could we?

*Learning outcomes:*

- Students will measure a table top with nonstandard and standard measurements.

*Suggested procedures overview:*

- Put students in groups, focus their attention, and assess their initial understanding of the focus questions.
- Have students measure a table with a straw (distribute different lengths of straws among the students).
- Measure length with in cm with a meter tape.
- Record information on student lab sheets.

*Scoring guide for *

*Top level*

- Carefully place the measuring device at a starting point, accurately iterates it (if necessary) and counts units from the starting point to the ending point. Deals with the last unit by rounding or making it a fraction.
- Carefully place the measuring device at a starting point, accurately iterates it (if necessary) and counts units from the starting point to the ending point. Notices the last part isn't a unit, but unsure what to do.
- Paces the measuring device near a starting point. Miss counts, sloppy iteration (if necessary) and misses the starting point and the ending point by a significant amount. Not concerned about the last unit not being a total unit.

*Lower level *

#### Exploration

- Ask the students how they can measure their table.
- Form students into groups and give them a straw (so there are at least three different lengths) to use as a measuring tool.
- Have students measure the length and width of tables with straws and record their results. (Observe technique students use to measure table)
- Bring the students back together as a class.
- Tell. Share your measurements by writing it on the board.

#### Invention

- Ask about the measurements.
- Discuss why they are different?
*Different lengths of straws and some may have rounded up and others rounded down because the length is so long.* - Show the students a meter tape (with centimeters marked).
- Ask. How are they different than the straws?
*They are all the same length (non standard measurement) and they are smaller.* - Ask. Can you measure the same table with it?
- Tell. Measure the table and record the results.
- Tell. Share your measurements by writing it on the board.
- Have them compare their results and discuss the differences.
*The result, most probably will not be the same. Focus on the results as being closer than the measurements with the straws. Develop the idea of standard unit now and later work on accuracy.* - Ask. Why do scientists want to use a meter tape to measure?
*Accuracy to measure change and communicate better.* - Introduce the term
*standard unit*of measure. - Ask. Why it is important to have standard measurement?
*To have a standard unit that all people understand so we can communicate better. Point out that if you want to know if a table will fit a certain space using a non standard unit (arm length, back to back foot measurement, ... ) can provide enough accuracy to get the job down. It's when you need to communicate to another person, the standard unit becomes necessary. Buy carpet, table cloth to fit the table, ...* - Ask. What kind of measurement a carpenter uses on their tape measure?
- Ask. How to measure a person’s height?
*Accept all answer.* - Ask. How to weight a person?
*Accept all answer.* - Ask. How to measure the amount of pop in a bottle? …
*Accept all answer.* - Tell. A measuring tape is used to measure linear measurement: the distance between two points.
- Ask. What are examples and non examples of linear measurement?
- Randomly mention things to measure and ask if they would measure those items with a tape or not.
- If students need practice finding the numbers on a tape, put them in pairs and randomly call out certain numbers for them to locate on the meter tape.
- Have the students measure a large variety of items with their meter tape, recording information on a
*How Long Is It*lab sheet. - Have students compare measurements.
- Discuss for instance why one person’s foot may have measured longer than the next person.
- Ask. How people use measurement outside of school?
- Ask. How important is it to be accurate?
*Depending on the age of your students you may or may not want to focus on accuracy. Young children have a difficult time accurately lining up rulers from start to finish and like with the straws end to end from start to finish. If your students are ready to proceduralize measuring then have them discuss and you can write a procedure to measure linearly.* - Ask. Why is a standard unit of measurement is so important?
