Talk to children about Israel as a nation of innovation, invention and limitless potential using our imagination and resources available to us.
When we talk about Israel with our children we can express Israel in terms of unlimited potential. Israel was mostly sand dunes when the early pioneers arrived to the land of Palestine. Now the cities are centers of technology and science.

How can this be related to children? Give your child time in nature for exploration, imagination and creation. Be sure to give your children time to exercise their powers of inquiry, exploration, observation and ingenuity. Sometimes just an awareness of natural resources (wind, sun, water) combined with common household items can contribute to some simple experiments that can be done at home.
Solar Energy - Light from the Sun
Scientific concepts:
- The sun's light energy can be converted into plant energy.
- The sun's light energy can be converted into warmth.
- The sun is the primary source of light, energy and warmth on earth.
1. Scientific Activity: Do seeds need sunlight to grow? Compare the difference between growing a seed in the dark and growing a seed in the sunlight. Concept: Producers (plants) use the sun's energy to live and grow. Take two empty CD cases, some potting soil, and four seeds. Place some soil in the CD case and two seeds. Close the CD cases. Put some drops of water into the cases. Cover one case so that it cannot receive sunlight. Put the other case under sunlight. Ask your child to predict what will happen. Will the seeds grow at the same rate? Put some drops of water in both cases when you see the soil getting dry, a couple drops a day or every other day. Observe the seeds daily over the next few weeks.

Planting corn seeds in a CD case provides the seed roots with
nutrients enabling the shoots to grow towards the sun. It also
makes it possible to see the roots as they grow. Water can be
dripped into the CD case from the opening in the top where
the hinge is located.

Your seeds will sprout and grow and the roots will be clearly visible.

Compare the seeds that grew in the sun to the seeds that did not have sun. How are they the same? How are they different?
2. Build a solar oven. Concept: The sun's light energy can be tranformed into heat that is hot enough to melt food.
Materials: A Pizza Box, Tin foil, wooden dowel, black paper, clear plastic wrap, paper plate, graham crackers, chocolate and marshmallows.
Ask children to predict what will happen to the chocolate and marshmallows in this solar oven.
Method: Affix tin foil to a portion of the top of a pizza box. Secure clear plastic wrap tot he remainder of the pizza box cover. Secure black paper to the inside of the pizza box. Place a plate of s'mores inside the solar oven, prop the lid open so that it reflects the sun. Place a plate of s'mores on a counter away from the sun for comparison. Ask your child to predict what will happen. Which plate's chocolate will melt first? If desired, place a thermometer inside the solar oven to see what the temperature is and record the temperature over time. Ask: What happened to the chocolate and marshmallows, and why?
