Things that fly

FLIGHT

Aim: To learn about flight and aerodynamics.

In your groups of 3 you will make a paper plane and measure its distance and behaviour.
In groups of 3 you will make a water rocket and record its distance and behaviour.

Definition:

4 forces of flight:

Gravity
Thrust
Drag
Lift

Paper Plane:

Material:

1. 1 paper

2. ruler

3. paper clip

Steps:

1. fold the paper in half make sure it is made as a long strip
2. the 2 triangles at the top, the corner of the triangle should go up to the lines
3. fold the side with the triangle with the tip of the triangle close to half, then make 2 more triangles, do the same thing at the (2nd line), fold the small triangle up then fold it into a half, then fold the wings make sure they are the same then your done.

Findings:

Plane Type	Distance	Behaviour
Normal	0.5m	it went straight
Ailerons	0.3m	it curved up then to the ground
Paper clip	0.1m	it fell to the ground

Conclusion:

filtration plant

Aim: To make a filtration plant using household materials.

Water Filtration Plant

What is filtration?

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass.

Examples are:

Air

Oil

pool

water

Materials

1.Funnel

2.Container

3.Filter paper

4. sand

5. pebbles

6. dirty water

7. scissors

8. cup

Process - ( use verbs or doing words in each step )

Step 1

Cut the bottle so the bottle is in two even parts and the top half of the bottle can be used as a funnel and the bottom can be used as a container

Step 2

Put the top half of the bottle upside down on top of the bottom piece.

STEP 3

Make a cone shape out of your filter paper and Add layers of sand inside of that cone and place the cone right way up inside of the funnel

STEP 4

After you have done that add 1 cup of pebbles and pour the pebbles inside the funnel aswell then Get 1 cup of dirty water

STEP 5

Pour the dirty water into the funnel slowly and watch what the magic happen

Findings

I found out that if you pour the water fast the water would not really change but if you pour it slowly it would turn out pretty good

Drops per minute: 23

Water color: Light brown

Conclusion: The water looks not really safe to drink but it made a difference I also found out how to make this it is a fun thing to do for science and i would really recommend doing it

After you have done all of that you need to tip the dirty water out and get another cup and the water that is at the bottom of the bottle needs to go in the cup.

After that, you need to make another cone and place the cone on top of the pebbles then pour the water slowly inside that cone.

After that happens drops would come out and the water should be cleaner than the first lot that you have done.

Plants

AIM: TO LEARN ABOUT THE NATURE OF PLANTS

Carnivorous Plants

Plants fall into two categories:

1. Evergreen

2. Deciduous

Deciduous

Evergreen

Find three examples of each:

Evergreen:

Deciduous;

LEAVES

Simple Compound

Activity: Choose a leaf and do a leaf rubbing. Once you have done the rubbing, cut it out and glue it on the tree.
