MEASURING MATTER: How do we measure things?

Introduction

In the laboratory of the scientist Atomy James have entered to steal. The police have found a very strange scene... Everything was a mess! Many of the substances and objects in the laboratory were not in place and had changed. To put them back in their place you need to look at some of their properties.

Do you dare to become a scientist for a day and help Atomy to restore order in her laboratory? Would you be able to measure the volume, mass and temperature of these objects and substances?

 

                                             Be Part of a Patient's Diagnosis: Become a Medical Laboratory Technician

Task

In order to help Atomy, you will carry out a series of experiments related to the following properties of matter: volume, mass and temperature. In groups of 4 you will have to measure different objects and substances according to one of these properties. Once you have made the measurements you must complete a poster in the padlet application where you will briefly explain your experiment and the results. Finally, you will make a mini oral presentation in which you will present your work to your classmates. You must use English to communicate and negotiate the final product.

Therefore, the main objective of this task is to consolidate the properties of matter throughout different experiments in order to complete a digital poster and present the results and findings to your mates. 

Process

Before starting with your experiment, you must check the information about the properties of matter you will find in the nearpod presentation of the unit and in this webpage (https://www.turtlediary.com/lesson/measuring-matter.html).  Then, watch the following video: "Matter and its properties" (https://happylearning.tv/en/matter-and-its-properties/).

Each group will carry out the experiment assigned by the teacher. Follow all the steps carefully and complete the final poster. In this link you will find a template for your task https://padlet.com/afernandezote/c3650huk7a0w6jd5 .

 

EXPERIMENT 1: MEASURING LIQUID VOLUME

Watch this video: https://www.youtube.com/watch?v=CrFYdnWXgFE 

What you need: containers, water, colourants, measuring jar

What to do:

1. Observe the different containers (different shapes and sizes) with coloured water. 

    - Which one has the most volume?

2. Pour the contents of the three containers into a measuring jug.

3. Write down the measurement of each liquid.

4. Answer the following questions and complete the final poster:

    - What instrument do we use to measure the volume of liquids?

    - What standard unit do we use to measure the volume of liquids?

    - Once the experiment has been carried out, which one of the coloured liquids has the most volume? Explain your answer.

 

EXPERIMENT 2: MEASURING MASS

Watch this video: https://www.youtube.com/watch?v=A0DdQe66_aY

What you need: cushion, book, pencil, bottle, calculator and a scale

What to do:

1. Look at the cushion, the book, the pencil, the bottle of water and the calculator.

    - Which is the heaviest object? and the lightest? 

2. Weigh all the objects on the scale. How heavy are they?

3. Write down the measurements obtained.

4. Answer the following questions and complete the final poster:

    - What instrument do we use to measure the mass of objects?

    - What standard unit do we use to measure mass?

    - Once the experiment has been carried out, which one of the objects is the heaviest?

    - Order them from highest to lowest mass.

 

EXPERIMENT 3: MEASURING TEMPERATURE OF WATER

Watch this video: https://www.youtube.com/watch?v=DFwOfEcjI58

https://www.youtube.com/watch?v=DFwOfEcjI58

What you need: containers, water, kettle, ice, thermometer

What to do:

1. Take three containers and pour iced-cold water into one, boiling water into another and room temperature water into the last.

2. Insert the thermometer in each one of them and observe how the temperature varies.

3. Write down the temperature of each container.

4. Answer the following questions and complete the final poster:

    - What instrument do we use to measure the temperature?

    - What standard unit do we use to measure temperature?

    - Once the experiment has been carried out:

          * Which is the hottest water? Why?

          * Which water has the lowest temperature? Why?

Evaluation

Your work in this task will be evaluated through a rubric. The rubric will include:

    - Collaborative work:

           1. Contribution 

           2. Cooperation 

           3. Focus on task 

    - Digital poster (padlet):

          1. Content accuracy 

          2. Organisation 

          3. Mechanics 

    - Communicative competence:

         1. Display: organisation and content 

         2. Fluency and pronunciation: speaks clearly 

         3. Grammar and vocabulary

All items will be assessed according to a 1-4 scale*.

*Scale: from 1 to 4 ( 4: Excellent; 3: Good; 2: Fair; 1: Needs improvement)

 

Conclusion

After this experiment you are a little bit closer to becoming a great scientist! Now you are able to:

- Measure different types of matter. 

- Compare objects and substances according to their volume, mass and temperature.

- Create a collaborative poster using a digital tool.

- Make an oral presentation of an experiment findings.
