Answer 1

GRADES 4-6 EXPERIMENTAL PROJECTS

ELECTRICITY

1. Understanding Electrical Conductors and Insulators

2. Demonstration of principals; how is current affected by type of conductor, temperature, filament, etc.

3. Compare material and objects for conductivity.

4. Compare electromagnets for strength.

5. Principles of fluorescent lights; how do they compare with filament bulbs, in effectiveness and cost.

6. Compare wires for conductivity.

7. Does the wattage of a light bulb affect the amount of heat given off?

PHYSICS

1- How metals compare in conducting heat.

2- How metals compare in density

3- Egg Floatation (buoyancy)

4- Efficiency of different types of steam engines

5- How does the amount of oxygen affect the rate of burning?

6- Does Temperature affect Solubility?

7- Are some substances more soluble than others

8- How do Airplanes fly? What is the best wing shape?

9- How do waves carry energy?

10- How do magnets work? How are they made?

11- Compare densities of different gases

12- How Light is Affected passing through water e.g. viewing objects under water, formation of rainbows
.
13- What limits the speed of a boat, a truck transport.

14- Submarine; How to sink? How to float?


CHEMISTRY

1- Chemical Change and the factors that affect the rate such as heat, light and catalysts

2- Acid and basic solutions, how are they produced, how can they be modified; practical considerations in soil, lakes, food; acid or basic solutions around the house.

4- The effects of salts on the freezing point of water.

5- Fire must have air to burn
.
6- Effect of Acids on teeth, bones and eggs

10- The effects of salts on the boiling point of water
.
METEOROLOGY

1. Day Length - Why the day length changes in different days of the year? Calculate or record length of days and nights over a period of time; what effects do the changes have on things like household plants, pets, etc

2. Air Movement - Is air in your house the same temperature at floor level and near the ceiling? How could you spread heat more evenly through the house

3. Dew - Does it form on clear or cloudy nights? What other frost factors increase the amount of dew? Can you measure how much dew is formed in a square meter.

4. Temperature. - How does the temperature change during the day? What time is usually the warmest? Can you construct your own thermometer to keep your own records.

5. Rain - How does a rain gauge work? Measure the rainfall over a period of time and compare it with the daily weather reports. - Principles of cloud seeding and other weather modification.

BIOLOGY

Insects:

1. Personal observations on life cycle

2. Feeding habitats,

3. Population, flies, bees, butterflies
.
4. What attracts insects? Heat or light?


Nutrition:

12. Minerals in foods (Compare foods or fruits for dissolved minerals)

Studies:

21. How pet mice respond to different types of food (pellets, crushed, solid)

22. Taste Buds

Plants:

31. Why do plants grow towards light?

32. The effects of gravity on seed germination

33. How water moves through the plant

34. How plants reproduce and factors that affect the process

35. Why do plants move?

36. How do plants get nitrogen

37. Does gravity affect plant growth?


Soil:

41. The importance of earthworms to soil and plants

42. The effect of soil components and organic matter on growth of plants.

Field Studies:

51. Plant and animal life in the school grounds

52. Plants and animal life in a creek or stream

53. Plants and animal life in a grassy field

54. Plants and animal life in a tree

55. Plants and animal life in a home garden

56. Plants and animal life in a balanced aquarium

57. Plants and animal life during winter

Answer 2

When i was about that age, the experiment that i found so fascinating was on the topic surface tension. The materials are egg, water, a beaker (or any glass that can contain water will do), and a salt. The test is whether the egg floats on the water or sinks. And what about if salt is added to the water?

Try it in your home. You can formulate a hypothesis and derive a conclusion out from that very simple experiment.

Answer 3

I would go with something like electricity (obviously using all caution that can be used, and a small voltage like 6 volt battery as the source) too many people go with the volcano idea. Question could something like "What is the best conductor of electricity?" Easy answer but it would be a fun thing for a 9 year old to learn about and pretty easy do.

Answer 4

The food color to the flower water is a really good one because you can see it gradually happening, and can mark results.
The make-your-own-volcano thing is awesome too for boy or girl because all you have to do it add vinegar to the baking soda and every kid like to make things blow up.

Answer 5

A good one for a girl would be to try to predict the reaction of adding food-colored water to flowers - what would happen to the flowers?

Answer 6

She could do an egg drop? In my 5th grade science fair we saw how long it took popcorn to pop? or what brand of gum lasts longest. Tell her good lucK!

Answer 7

I think I'll have to agree with the food coloring with flowers one. I've never done it myself (we didn't have science fairs), and it seems pretty interesting!

Answer 8

Well it depends on how long you have. I think crystals might be a good idea. Simple, all you have to do is wait.

Answer 9

Don't know how long you have - but get two mice. Feed one of them junky food and one of them healthy food and see what happens. Which one moves faster? - which one sleeps more? - etc.
