Front

Investigating the effect of different types of fertilizers on the growth rate of tomato plants.

Back

• Category: Life Science

• Explanation: This problem deals with living organisms (tomato plants) and biological processes (growth). Life science focuses on the study of living things.

Front

Designing and building a small robotic arm that can sort different colored blocks.

Back

• Category: Robotics

• Explanation: This problem involves the creation of a machine (robotic arm) that performs a task automatically, which is the core focus of robotics.

Front

Studying how temperature changes affect the melting point of various types of ice.

Back

• Category: Physical Science

• Explanation: This problem investigates the properties of non-living matter (ice) and how they are affected by physical conditions (temperature changes and melting points). Physical science deals with the laws of nature and non-living materials.

Front

Determining if a new type of biodegradable plastic can break down faster in ocean water compared to regular plastic.

Back

• Category: Physical Science

• Explanation: This problem involves studying the properties and reactions of non-living materials (plastics) and their interaction with a non-living environment (ocean water).

Front

Exploring the behavior patterns of common garden ants when exposed to different food sources.

Back

• Category: Life Science

• Explanation: This problem focuses on the study of living organisms (ants) and their biological behaviors.

Front

Developing a program that allows a drone to automatically follow a moving object without human control.

Back

• Category: Robotics

• Explanation: This problem is about creating automated systems and programming machines (drones) to perform tasks autonomously, which falls under robotics.

Front

Analyzing the chemical composition of rainwater in different urban areas to check for pollutants.

Back

• Category: Physical Science

• Explanation: This problem involves the chemical analysis of a non-living substance (rainwater) and its components, which is a key area of physical science (specifically chemistry).

Front

Discovering if a certain type of plant extract has properties that can stop the growth of bacteria.

Back

• Category: Life Science

• Explanation: This problem investigates the effect of a substance (plant extract) on living microorganisms (bacteria), which is a biological study.

Front

Creating a sensor system that can detect when a plant needs water and automatically turn on a small pump.

Back

• Category: Robotics

• Explanation: This problem involves designing and building an automated system with sensors and mechanical components to perform a task, aligning with robotics.

Front

Examining how the amount of exercise affects the heart rate of teenagers.

Back

• Category: Life Science

• Explanation: This problem studies the physiological responses (heart rate) of living organisms (teenagers) to a biological activity (exercise).
