3. What are the stages in a butterfly’s life cycle?

4. How does the human heart work?
A picture of the heart showing its parts. Call out boxes explaining the function of each part.

5. What is the carbon cycle?
Use call out boxes to explain the different parts of the cycle. For example, have a call out box showing how plants remove carbon dioxide and another call out box showing how animals contribute carbon dioxide.

6. What are the different classes of animals?
You could list these and have pictures of animals that represent each. Also you might want to have a call out box with specific characteristics of each class.

7. How does pigment in the skin of animals act as sunblockers?  SUNBLOCKERS

8. How do the shapes of leaves differ?
You can make a collection of pictures of leaves with different shaped leaves. Identify the plants the leaves come from as well as the name that scientists give to each specific leaf shape.

9. How do the vein pattern of leaves differ?
You can make a collection of pictures and/or drawings of leaves with different patterns of veins.  Identify the plants the leaves come from as well as the name that scientists give to each specific vein pattern.

10. How do the grouping of leaves on a stem for different plants differ?
You can make a collection of pictures of leaves with different grouping. Identify the plants the leaves come from as well as the name that scientists give to each specific group type.

11. What is the difference between the leaves from dicot plants and monocot plants?
You can make a collection of pictures and/or drawings of leaves from dicot and monocot plants.  Identify the plants the leaves come. Do have  call out boxes  that describe the characteristics of each type of leaf.

12. What is the difference between the flowers from dicot plants and monocot plants?
You can make a collection of pictures and/or drawings of flowers from dicot and monocot plants.  Identify the plants the leaves come. Do have  call out boxes  that describe the characteristics of each type of flower.

13.Question: What qualified Ceres to be a dwarf planet while Earth’s Moon is just a moon?

14. Why does only one side of the Moon face Earth?  MOON MOTION

Chemistry

1. What is yeast? Why is it used to make break?

2. What is the difference between atoms and molecules?

3. How does sunblock keep a person from getting sunburned?

4. What does the SPF rating on sunblock mean?
You could show the different brands of sunblock with different SPF ratings. In call out boxes , describe how to use the product so that you are best protected if you are exposed to sunlight for several hours.

5. How is carbon-14 produced in Earth’s Upper Atmosphere? CARBON-14

6. What is a photon?  PHOTON

7. What is an isotope?
Show diagrams of isotopes, such as hydrogen, deuterium, and tritium. Use call out boxes to to add information about each of these isotopes.

8. Why does popcorn pop?  POPCORN

9. What is surface tension?  SURFACE TENSION
SURFACE TENSION VIDEO

10. How do soap bubbles form? SOAP BUBBLES

Earth Science

1. What is lightning?
A display of how lightning is produced–what attracts lightning–the different kinds of lightning.

2. What do the symbols on a weather map mean?

3. How does a compass work?

4. What is the water cycle?
Show why some say that we might be drinking the same water that a dinosaur drank millions of years ago.

5. What are the different kinds of clouds?

Use call out boxes to describe diagrams or photos of different types of clouds. You can also add call out boxes to describe the type of weather that each cloud type is associated with.

6. How are clouds formed? CLOUD FORMATION
