[ML19] Grade 1 - How Far?

[Aleeza]

Grade 1 - Session 9: “How Far?”

Architect: Aleeza Ayaz - Markhor3D
Session Length: 50-60 minutes

---

Session Overview:

In this engaging session, students dive into exploring distance by interacting with the MeasureLab’s distance sensor. Through fun games and movement-based activities, they’ll observe how the sensor screen changes based on how close or far objects (and even themselves!) are from the sensor. By the end, students will have a playful, intuitive sense of distance, sparking curiosity about spatial relationships and everyday measurements.

---

Learning Objectives:

In this session, students will:

1. Use the distance sensor to see how the screen changes when they or objects move closer or farther away.
2. Experiment with placing themselves or objects at different distances and observe the number on the screen change.
3. Develop an intuitive understanding of distance without focusing on exact measurements.

Equipment Required:

1. MeasureLab with a distance sensor.
2. Various objects of different sizes (e.g., toys, books).
3. A clear area for students to move in front of the sensor.
4. Laptop or PC for displaying distance measurements.
5. Worksheets with images of different distance scenarios.
6. Colouring materials (crayons, coloured pencils, markers).

---

Teaching Aids:

1. Projector (optional).

Preparation:

This step has to be done before the session on each workstation/apparatus by the teacher/session instructor:

1. Make sure that each computer has Physlogger installed and can detect the Measrelab when connected to it using the provided cable.
2. Each Measurelab should have access to a power outlet for sensors that require external power. For this session, we will use the Distance Sensor which needs external power.
3. Connect the Distance Sensor to the MeasureLab in the following port:

5. Connect the Measurelab to your computer and open the provided session file.
6. Your setup will look like this:

Introduction: (10 minutes)

1. Introduction:

   • Start by projecting images of everyday things, like a child holding a balloon close and far, or a cat near and far from a toy.
   • Ask the class:
     • “How do you know if something is close to you or far away from you?”
     • “Yes sometimes we may use a measuring tool!”
       -
       

2. Building Curiosity:

   • You may show a picture of someone reaching for a cookie jar that’s either near or far.
   • You might ask:
     • “If the cookie jar is far away, what happens? Can you reach it easily?”

3. Activity Teaser:

   • Introduce the MeasureLab tool and the distance sensor.
   • You may say:
     • “Today, we’re going to play a fun game to see how close or far we are from something. This tool will help us see it on the screen.”

4. Interactive Demonstration:

   • Invite a student to stand in front of the sensor and move back and forth.
   • Encourage reactions: “Whoa, look at the screen! Did you see it change when you moved?”

Hands-on Exploration: (15-20 minutes)

Distance Challenge Game:

1. Students as the Objects:

   • Play a game where students become the objects. You may say:
     • “Who can stand the farthest from the sensor and make the screen change the most? Let’s see!”

2. “Dance and Freeze” Game:

   • Students can dance in front of the sensor. When you say “Freeze!” they stop, and the sensor reads their distance.

3. Object Fun:

   • Use playful items like a toy dinosaur or a fluffy ball. Ask students to move them near and far from the sensor. You may have a wind-up toy like a car which moves away or towrads the sensor so that students can see the distance change with the motion of the toy car.
   • Encourage questions like:
     • “What number does the screen show when the dinosaur is close?”
     • “Does it change when we move it far away?”

---

Guided Activity (15-20 minutes):

Worksheet Activity:

1. “Near or Far”:

• Students will draw a picture of any object that is close or far. For example, they may draw a tree close to them, and one that is further away.

2. Number Analysis:

• Show pictures of objects at different distances.
• Students will draw a short line connecting the picture to the correct distance.

3. Classroom Adventure Map:

• Create a fun “map” of the classroom. Mark spots like “Teacher’s Desk,” “Door,” “Window,” and have students guess which spot is the closest or farthest from the sensor.

Wrap-Up and Reflection (5-10 minutes):

1. Review and Celebrate:

   • Recap the fun activities:
     • “We saw how things look different on the screen when we move near and far. You all did a great job finding out who was closest and who was farthest!”

2. Reflection Questions:

   • “What was your favourite part? Did you like being the closest to the sensor?”
   • “Did any object make the number on the screen change a lot? Which one?”

3. Encouragement:

   • “You were all amazing explorers today! Keep noticing things around you that are close and far. Next time, we’ll discover more fun things!”

Glossary:

1. Distance: How far or close something is.
2. Sensor: A tool that helps us see or feel things, like how far something is.
