Activity Title: Heat Me Up!

Science Processes Skills: Observation, Measuring, Formulating Hypothesis, and Critical Thinking

Instruction: The students will observe how two substances at the same temperature can contain different amounts of heat energy, helping them understand that heat and temperature are not the same.

Activity:

MATERIALS (per group):

•1 metal spoon (or any small metal object)

•1 plastic spoon

•2 cups of hot water (same temperature, measured with thermometer)

•1 thermometer (optional, for confirming temperature)

•Timer or stopwatch

•Tissues or towel for drying

STEPS

1. Heat water to about 60°C. Pour equal amounts into two cups.

2. Put the metal spoon in one cup and the plastic spoon in the other at the same time.

Wait 1–2 Minutes:

3. Let both spoons sit in the hot water.

4. After 2 minutes, remove the spoons and carefully touch the ends (the part that was in the water).

a. Which one feels hotter?

b. Why do you think that is?

GUIDE QUESTIONS

Q1. Did both spoons sit in the same temperature water?

Q2. Why does the metal spoon feel hotter than the plastic spoon, even though they were in water of the same temperature?

Q3.What does this tell you about how different materials absorb or transfer heat?

Activity Title: State Your Matter!

Science Processes Skills: Observing, Classifying, Communicating, Formulating Hypothesis, Formulating Models, Critical Thinking, Creative Thinking.

Instruction: After the students are divided into groups, each group will go outside the room to search and collect various materials within 10 minutes. Upon returning, groups will categorize their collected items according to what states of matter they fall under and they will also have to answer the following questions.

Activity:

Guide Questions:

1.   What characteristics did you observe to classify an object as solid, liquid or gas?

2.   What would happen if you heated or cooled one of the materials you collected? Would its state of matter change?

3.   How can solid, liquid, and gas affect our daily lives? Do they matter to us?

4. Based on what you have understood, create a simple model that creatively represents the properties of solids, liquids, and gases using materials available with you.

Rubric:

10 points (Excellent) - The model creatively and accurately represents the properties of solids, liquids and gases, using available materials in an innovative way, with clear labels and a well-organized design.

8 points (Good) - The model effectively represents the properties of solids, liquids and gases, with some creativity and good use of materials, but may lack some clarity of organization.

6 points (Fair) - The model partially represents the properties of solids, liquids and gases, with limited creativity and adequate use of materials, but may have some errors or lack of clarity.

4 points (Need Improvement) - The model does not accurately represent the properties of solids, liquids and gases, lacks creativity, and/or demonstrates poor use of materials.

Activity Title:

Ready, Set, Race!

Science Processes Skills:

Observing, measuring, predicting, formulating hypothesis, and interpretating data.

Instruction:

1. Create and two groups in class and one will be ball and one will be car.

2. Measure a 5-meter straight track

3. Hold the car backwards and release, as well as the car.

4. Use a stopwatch to record how long it takes to travel the straight track.

5. Repeat the activity 3 times and take the average time.

6. Calculate the speed using the formula and list the result in a table.

Activity:

Two objects (car and ball) will be racing in a 5-meter straight track. After three times trial, calculate the average time and the speed of car and ball.

Guide Questions:

1. According to the average times and speeds you determined for the car and the ball over the 5-meter track, which object moved quicker on average?

2. What factors do you believe contributed to the difference in their speeds?

3. Why it is important to repeat the experiment 3 times?

4. What tools or materials do we need to measure time accurately?

I. Activity Title: Heat is on!

II. Science Processes Skills: Observing, Classifying, Measurement, Inferring, Predicting, Formulating Hypothesis, Critical Thinking.

III. Instruction

The students will be divided into 5 groups. Each group has three glass containers: one contains 50°C water, another one contains 20°C water, and the last container is an empty container. Put the 50°C water and the 20°C water together in the empty container. Observe the temperature using the thermometer.

IV. Activity

GUIDE QUESTIONS:

1. What was your initial observation before you did the experiment?

2. What is the final temperature of the container when you combine the 50°C and 20°C water into an empty container?

3. Did the two systems reach thermal equilibrium? Yes or no, and why?
