Development:
Step 1 : ( Teaching Activity 1) – Remedial Pupils
- Teacher shows 2 containers with different shape and size contains colored water. Pupils are asked to mention which container has more water.
- Pupils write their answer in small pieces of paper.
- Teacher ask two pupils come forward and ask them to pours the water into a beaker each others.
- Teacher repeats this activity using others set of bottle. (2 containers with different shape and size contain colored water).
- Teacher and pupils do activity guess and check.
- Teacher ask conclusion from excellent pupils and make conclusion that the volume of water should not be compare directly using different containers.
Step 2: Reinforcement Pupils
- · Pupils are ask to read scale on a beaker.
- · Teacher shows a video ( Video 2).
- · Teacher does demonstration.
- · Pupils are ask to read level of water in a beaker. Teacher may use colored water to attract pupils attention.
- · Teacher also may ask 1 pupil to come forward and pours water in a beaker. After that asks, other pupils to read the scale.
Others suggested activities:
Materials:
· Containers in cup, pint, quart, and gallon size
· One gallon of apple juice and 30 paper cups
Procedure:
1. Warm-up: Bring in containers that are cup, pint, quart, and gallon size. (Have an actual gallon of apple juice.) Ask students if they can identify the unit size of each container. Ask students what size containers they buy at the store and what liquid is normally contained in these containers.
2. Motivate the Lesson: Ask students how many cups of juice they believe they can pour from a gallon of juice. Have students explain their reasoning. Pour the apple juice into cups to see how many cups are in one gallon. (Let the students drink the apple juice.)
3. Explain that they could have calculated the number of cups of apple juice by using unit conversion. Ask the “Question of the Day”.
4. Proceed through the lesson examples and explain how to read the unit conversion chart and the “Gallon Man” visual representation.
5. Stress the importance of when to multiply and when to divide by having each student write down, verbally repeat, and use the rules in the provided examples.
