1. Plant Growth Experiment
In this project, you will explore how different levels of sunlight affect plant growth. By creating a hypothesis such as, “If plants receive different amounts of sunlight, then the plants with more sunlight will grow taller,” you can set up an experiment with identical plants placed in varying light conditions. Measure their growth over several weeks and document your findings.
2. Water Filtration System
This project allows you to investigate how effective different materials are in filtering water. By hypothesizing that “If I use different materials to filter water, then the cleanest water will come from the sand filter,” you will gather materials like sand, gravel, and activated charcoal. Create a filtration system and compare the clarity and quality of the water after filtering.
3. Baking Soda and Vinegar Volcano
Create an exciting volcanic eruption using baking soda and vinegar. Formulate a hypothesis such as, “If I add more baking soda to the vinegar, then the eruption will be bigger.” Construct a small volcano with clay or plastic, measure the quantities of baking soda and vinegar, and observe the reactions to see how they affect the size and duration of the eruption.
4. Paper Bridge Strength Test
Explore the principles of physics by testing the strength of different paper bridges. Hypothesize that “If I use thicker paper, then the bridge will hold more weight.” Build bridges from various paper types and gradually add weights until they collapse, documenting the maximum weight each bridge supports.
5. Solar Oven
In this project, you will create a solar oven using a pizza box, aluminum foil, and plastic wrap to harness the sun’s energy for cooking. By observing how effectively your oven can reach high temperatures, you can learn about renewable energy and the greenhouse effect.
6. Magnet Strength Comparison
Investigate the strength of different magnets by testing how many paper clips each can hold. Create a hypothesis like, “If I use a neodymium magnet, then it will hold more paper clips than a ceramic magnet.” Gather various magnets and record your observations.
7. Homemade Lava Lamp
Create a lava lamp using water, oil, food coloring, and Alka-Seltzer tablets. This project demonstrates the principles of density and chemical reactions. You can hypothesize about the effects of different liquids and observe how they interact.
8. Crystal Growing Experiment
Explore the fascinating world of crystals by growing your own using sugar or salt. Formulate a hypothesis about which substance will grow the largest crystals. Set up your experiment and observe the growth over several days.
9. Egg Drop Challenge
Design a protective structure for an egg to survive a drop from a height. Hypothesize that “If I use more cushioning materials, then my egg will be less likely to break.” Test your designs and see which one succeeds in protecting the egg.
10. DIY Weather Station
Construct a simple weather station using everyday materials to measure temperature, wind speed, and rainfall. By creating a hypothesis about local weather patterns, you can collect data over time to analyze and compare.
11. Homemade Slime
Experiment with making slime using glue, baking soda, and contact lens solution. You can hypothesize about the effects of varying the ratios of ingredients on the texture and stretchability of the slime.
12. Seed Germination Study
Investigate how different conditions affect seed germination. Hypothesize whether light or dark conditions will yield more successful germination. Plant seeds in various environments and record your findings.
13. Static Electricity Experiment
Explore static electricity by rubbing balloons on different materials. Hypothesize about which material will create the strongest static charge and test your predictions by observing how the balloons interact with small objects.
14. Density Tower
Create a density tower using liquids of different densities (like honey, water, and oil) to visualize how they layer. You can hypothesize about the order of the liquids and test your predictions by carefully pouring them into a container.
15. Solar System Model
Build a scale model of the solar system to understand the relative sizes and distances of planets. This project can include a hypothesis about the size of planets in relation to each other, allowing for creative representation.
16. Sound Wave Exploration
Investigate sound waves by creating a simple instrument, such as a rubber band guitar. Hypothesize how changing the tension of the rubber band affects the pitch, and document your observations as you play different sounds.
17. Insect Observation
Observe and document the behavior of insects in your backyard. Formulate a hypothesis about their activities or habitats, and keep a journal of your findings over several days to analyze patterns.
18. Water Cycle in a Bag
Create a
