Скачать или смотреть Science project DIY Hydraulic crane machine from cardboard - Science project working model

A creative and educational project! Here's a step-by-step guide to make a hydraulic crane machine from cardboard using a syringe:

Materials Needed
Cardboard (for base, crane arm, and other components)
Syringe (10-20 ml)
Water
Scissors
Glue or hot glue gun
Ruler or straightedge
Pencils or markers
Tape (masking or duct)
Small weights or beads (for counterweight)

Step-by-Step Instructions
Step 1: Design and Plan
1. Research and study the design of hydraulic cranes.
2. Sketch a basic design, considering the crane's size, shape, and movement.
3. Plan the syringe placement, water flow, and counterweight system.

Step 2: Cut Out Cardboard Components
1. Cut out the base, crane arm, and other components from cardboard.
2. Assemble the components using glue or hot glue.

Step 3: Create the Hydraulic System
1. Attach the syringe to the crane arm, ensuring it's securely attached.
2. Fill the syringe with color water,
3. Attach a small tube or straw to the syringe, connecting it to a small reservoir or container.

Step 4: Add Counterweight and Movement Mechanism
1. Attach small weights or beads to the opposite end of the crane arm, creating a counterweight.
2. Add a movement mechanism, such as a small pulley system or a lever, to control the crane arm's movement.

Step 5: Test and Refine
1. Test the crane by injecting water into the syringe, observing the crane arm's movement.
2. Refine the design as needed to achieve a smooth and efficient movement.

Step 6: Add Additional Details (Optional)
1. Add a cardboard or paper cover to the crane, creating a more realistic design.
2. Incorporate additional features, such as a rotating base or a lifting hook.
3. Create a themed environment around the crane, such as a construction site or a harbor.

Tips and Variations
Use different materials, such as foam board or 3D printed parts, to create a more durable and efficient crane.
Experiment with different syringe sizes or water flow rates to achieve a more precise movement.
Add sensors and programming to enable the crane to respond to environmental changes or user input.
Create a scaled-up or scaled-down version of the crane.

Science Project Considerations
Hypothesis: How does the design of the hydraulic system and counterweight affect the crane's movement and efficiency?
Variables:
Independent: Hydraulic system and counterweight design
Dependent: Crane movement and efficiency
Controlled: Water flow rate and syringe size
Data Collection: Record observations, measurements, and calculations related to the hydraulic system and counterweight's design and its effects on the crane's movement and efficiency.
Conclusion: Analyze results, discuss the hydraulic system and counterweight's design and its effects on the crane, and suggest improvements for future designs.
