ST1-WS-S: record observations accurately and honestly using observational drawings, labelling, informal measurements and digital technologies (ACSIS026, ACSIS039)
Explorers Centre Prompt: Explorers: Combine and Observe! Introduction - ● Explain to the students that today’s learning centre focus will be on the Explorers Centre. Students will be involved in observing (or looking closely at) what happens when different materials are combined with water. ● TPS ‘What do we do when we observe something? ● Explain that when we observe something we need to look closely at the materials and use our scientist eyes to explore and describe everything that we see (colour shape), feel (thickness, consistency) and smell using our words and recording our observations by drawing and writing. ● Show students the different materials available at the centre for observation. (Washing liquid, oil, tea, coffee, flour, rice). Explain that it is our job to choose 1 material and observe it carefully, then draw what we can see accurately and describe what we see, feel and smell. ● Model how to fold an A4 paper in half and accurately draw the jar with the oil inside on the left side of the crease. ● Model how to use our scientist eyes to observe the material ‘oil’. Asks students to TPS ‘describe what the oil ‘looks like using your observation eyes’ to your partner. Use the student’s responses to model how to draw what you can ‘see’ and label the drawing using adjectives to describe observations. For example bright yellow and thick. ● Choose a couple of students to smell and feel the texture of the oil and describe it using adjectives. Model how to label the drawing using adjectives to describe the smell and texture before the oil is mixed with water. ● Explain that now that we have described what we can see, feel and smell, our next job is to predict or hypothesis what will happen when we combine or mix the oil with water. TPS- what ‘predict’ means. Explain that to ‘predict’ or ‘hypothesis’ means that we are using our observations to guess what we think will happen when we combine oil and water together using our prior knowledge. ● Students TPS- Predict what will happen when we combine the oil and water and give a reason for your thinking. Teacher to record student’s prediction. ● Watch the video- https://www.youtube.com/watch?v=XmjpZCNfcOE Ask students to think about the following questions and TPS; What happened when the water was combined with the oil? Did the 2 materials mix together? How do you know? What happened when food colouring was added? Why do you think? (Oil and water do not mix. Oil is less dense than water and floats on top of the water. Food coloring is water-based so it mixes with the water. When you add the food coloring to the oil it will not mix. Once you add the oil to the water, the food colored droplets start to drop down since they are heavier than the oil. Once they drop into the water they start to dissolve and look like tiny explosions) (or fireworks). ● Model how to accurately draw the combined mixture of the oil and water on the right side of the crease. ● Model how to use our scientist eyes to observe the combined materials ‘oil and water’ and draw and label what is observed. Use student responses to record description above in detail. E.g Oil and water did not mix when combined. The oil floated on top of the water because it is lighter than the water. The water is heavier than oil. ●Encourage students to talk to their partner about their observations and describe what they can see to each other as they are working. Students can use the iPad to take a photo of their drawing and record their descriptions using the voice recorder to present to year 1. ●Explain to students that they can use any of the materials in the centre to combine with water and observe what happens. Remind them to draw, describe and label the materials before combining it with the water and to predict what they think will happen and how it will change once combined. Reflection: Students can talk about their findings to the class and explain their observations using their drawings and technology.
