Photosynthesis

/ What You'll Need:

? 2 plastic cups ? 2?4 sunflower seeds (or another fast-growing seed of choice) ? Potting soil ? Water ? Masking tape or label stickers ? Marker

0 What You'll Do:

1. Using tape or a label sticker, label one cup as "light" and one cup as "dark."

2. With the help and permission of a parent, fill each cup ? full with potting soil.

3. Add 1?2 seeds to each cup, spacing them half an inch apart.

4. Cover the seeds with a little more potting soil and gently pat it down. Note: Be sure not to cover the seeds with too much soil or to pack the soil too tightly.

5. Water the seeds thoroughly.

6. Place the cup labeled "light" near a bright window. Place the cup labeled "dark" in a dark room or closet where sun does not reach.

7. Answer questions 1?3 on your "What You Discovered" worksheet.

8. For the next week or two, check on the seeds every day and water when the soil begins to dry. Record your observations and answer questions 4?6 on your worksheet.

, What Does It Mean?

Plants need three basic things to grow: soil, water, and sunlight. Photosynthesis is the process plants use to turn sunlight into food. Photosynthesis relies on the energy from the sun to fuel the reactions that produce plant sugar. Plants that don't have light are unable to produce the food they need to grow and develop. But it's not just plants that need the sun, humans use sun energy too! The energy we gain from eating plants is the same energy that came from the sunlight used in photosynthesis. Now that you understand the process of photosynthesis, you can better appreciate the way we are connected to nature.

6 What You Discovered:

As part of your photosynthesis experiment, answer the questions below. 1. What is "photosynthesis"? Note: Refer back to the Photosynthesis module on the Science for Kids section

of the dTERRA? Science Blog if you can't remember.

2. What do you think will happen to the seed placed near the window?

3. What do you think will happen to the seed placed in the dark?

4. Which seed is growing faster? Why do you think this is happening?

5. Why do you think the seed placed in the dark isn't growing as fast?

6. What can the seed near the window do that the seed in the dark cannot?

3 What to Do Next:

? Eat an apple or another plant for a snack and think about how the energy it gives you started out as sunlight and was converted to plant sugars through photosynthesis.

? With a parent's help and permission, post a picture of your two cups on social media. Make sure to tag @doterrascience or use the hashtags #doterrascienceforkids and #featureme for a chance to be featured on the dTERRA Science Facebook page.
