TECHNOLOGY ENHANCEDPRIMARY SCIENCE SET(Students between 8 – 11 years old)


I. INTRODUCTION What is sound? How to keep my tea warm? Can I measure light? Primary school pupils are curious about their surroundings and have many science questions. Can technology help in teaching and learning science at Primary School?

The core of science is about investigating, exploring, asking questions, analyzing, and thinking – activities that technology can uniquely facilitate and deepen. The educational research studies showed that technology can work positively already at the primary school level. Based on our experience with the use of ICT we have developed the Primary Science with €Sense set. With the €Sense interface and its sensors, and the Coach software students can carry many different science investigations. ‘Real-time’ display of the “measured data” on the computer screen allows students to make direct links between the phenomenon and the graph. Such immediate feedback encourages critical thinking skills; students have time to spend on observing and interpreting, discussing and analyzing data. Students can quickly repeat the experiments, change experimental conditions and explore the results of the changes. This facilitates an interactive approach to the experiment. “Let’s see what happens if … “.By using our materials pupils learn not only basic science concepts but also develop mathematical skills in reading and interpreting graphs and language skills in using science terminology.The materials can be integrated into any science curricula or can be used on their own.

The set consists of: 1. €Sense Interface Package 2. Primary Science Kit3. Coach 6 Lite Software 4. Teacher Guides: Get Started Guide and Teacher Guide. 5. Students Activities Worksheets 6. Video Tutorials


II. OBJECTIVES

The objectives of the Primary Science Set are:

1. To help teachers to develop skills related to inquiry-based approach to science education.

2. To help teachers to introduce use of sensors into their science lesson.

3. To encourage and assist the use of technology by teachers and students.

4. To learn students basic science concepts around sound, light, heat and temperature.

5. To develop students’ mathematical skills in reading and interpreting graphs.

6. To develop students’ language skill by defining new science terminology.

7. To develop student’s basic abilities to do and understand scientific inquiry such as: - Asking and answering questions - Planning and conducting simple investigations - Predicting outcomes- Making observations - Testing hypothesis - Employing tools to gather data - Reading and interpreting graphs - Analysing data - Making comparisons- Using data to construct explanations and conclusions- Communicating investigations and explanation.

8. To promote inquiry classroom in which the student is the centre of the learning process. The following students behaviours characterize inquiry: - Students are working as scientists. - Students are taking responsibility for their own learning. - Students are working in cooperative groups.- Students are making decisions.- Students communicate their findings.- Students are showing interest in science.


III. DETAILED PRODUCTS DESCRIPTIONS (TENDER SPECIFICATIONS)

1. €Sense interface package Art.nr 009

€Sense is a simple USB measuring interface. It has three built-in sensors: sound (a), light (b), temperature (c), and the sensor input (e) for an external temperature sensor (d) which is delivered together with €Sense. The LED (f), located on the top, indicates interface initialization after connecting it to a USB port (g) of the computer. This LED and a built-in buzzer can also be used as actuators in Control activities.

Technical specifications:

Power supply via USB port, NO extra power supply needed

Resolution 12 bits

Max. sampling rate 40 kHz

Memory: Flash memory can be rewritten to update the firmware. For buffering of sampled data, €Sense is equipped with 32 kB of RAM memory which can contain maximal 16,000 samples.

Sensors: - Built-in Light sensor with three measuring ranges, 0 .. 1500 lux, 0 .. 15000 lux, and 0 .. 150 000 lux.

- Built-in Sound sensor with two measuring ranges, -9.5 .. 9.5 Pa (Pascal) for measurements of sound waveforms and 50 .. 110 dB (decibels) for measurements of sound intensities.

- Built-in Temperature sensor with a measuring range between 5 and 45 °C.

- External Temperature sensor (steel tube with a measuring range between -10 .. 120 °C, suitable for temperature measurement in liquids (water, mild acidic solutions) and air.

Actuators: - Built-in LED with 16 light intensity levels- Built-in Buzzer with 16 different sound levels

Connection to computer via USB

Data-logging software On computer: Coach Lite

5. Student Activities

The offered in the Primary Science Set student activities have inquiry-based character. In such activities student is the center of the learning process, work like a researcher, design and conduct own investigations. Teacher becomes a guide and a facilitator of this process. The materials consist of 3 parts, built around the use of the €Sense light, temperature and sound sensors. Each part consists of a set of units. Each unit can take 1-3 lesson hours. For each unit a student worksheet and a respective Coach software activity is provided. A student worksheet offers space for students’ observations, predictions, data, conclusions, etc. The worksheets (word documents) can be freely modified and printed for use in the classroom.

UNIT I – EXPLORING LIGHTIn this Unit students use the €Sense's light sensor to measure the light intensity of different light sources, investigate how light is reflected and how it travels in the following activities: I. How bright II. Graphing light III. Light and matterIV. Reflected light V. To see and to be seen

UNIT II – EXPLORING HEAT AND TEMPERATURE


In this unit students use €Sense and its external temperature sensor to investigate temperature in the following activities: I. Hot! Cold! Warm! II. Graphing Temperature III. Keeping warmIV. Getting the right temperature V. Cooling down VI. How to cool fasterVII. Melting VIII. Heat absorption IX. A chemical reaction

UNIT III – EXPLORING SOUNDIn this unit students use the €Sense's sound sensor and are introduced to sound and its properties in the following activities:I. What is sound? II. Making voice sounds III.
