The document describes an experiment where two bowls of water are placed in the sun and shade to observe how solar energy warms the water over time. Sara and Dani discuss what they know about energy and the sun before setting up the experiment with one bowl in sunlight and one in shade. They record the temperature of each bowl initially and after 30 minutes, 1 hour, and 1.5 hours. Their results show that the water in sunlight gets progressively warmer while the shaded water stays cooler, demonstrating how the sun transfers its energy to warm objects.

ABSORBING THE SUN’S ENERGY
Background Information: Without the sun there would be no life on Earth. Plants need the sun in order to make their food (photosynthesis) and we need the plants for our food, which gives us energy. he sun gives us light and heat; it can also produce electricity. Learning objectives: : To know some aspects about solar energy, what can we do with it, how to use it, why it is necessary for living. Description Put one of the cartons in a sunny spot and one in a shaded spot. Put the same amount of water in each e.g. 250 mls. Dip your finger in each and feel how hot or cold the water is. Leave the cartons standing for 30 minutes and then take the temperature of the water in each carton. Record your results: Dip your finger into both cartons again. What do you notice? Repeat the readings after one hour, and again after another 30 minutes. Record all the data in order to complete a chart.
BEFORE THE EXPERIENCE ï‚— Sara and Dani talk about what do they know about energy and sun. ï‚— They prepare two bowls of water and put on in the shade and the other one in the sun. ï‚— They feel how cold the water is using the finger and the thermometer.
Now in the shade, water is cold, about 19 grades at 11 a.m.
In the sunny spot, the water gets hotter, it’s about 21 grades.
Some hours later, the water is about 21,5 grades in the sunny spot..
Sara and Daniel recording the data.
Reflections: Sara and Daniel had a lot of information before doing the activity, because they know that sun heats water and our body. They enjoyed doing the experiment althought they kwnew the results in advanced. All the children enjoy experimenting, they did! Experience is the best teacher!
