Janyaa MM Details

Challenge Criteria:

  1. Students from grades 3 onwards and adults can participate in the Challenge.
  2. Each team will consist of maximum 5 participants.
  3. Each team has to be registered by Dec 31, 2018 online. Click here for registration
  4. Each team has to pay a registration fee of $50.
  5. Each team can choose any number of topics from Math & Science.
  6. Each team is expected to develop a hands-on learning model to explain a concept
  7. Any model developed has to be built using common materials including household materials and should not cross a total budget of $10.
  8. Each team must track the time spent on the Challenge idea to be able to assess the number of volunteer hours undertaken to build the model. Hours spent on the day of the Challenge will be accounted for separately.
  9. Each team has to submit a “Document” to the judges at the time of evaluationas per the format provided. Separate document is needed for each of the topics you choose.
  10. A journal documenting the engineering design process during the period until the Day of the Challenge, is mandated. No trifolds or any other document in print or digital is required. Journal log is expected to be a compilation of notes reflecting the engineering design process that was adopted to build the model being demonstrated. Engineering design process includes the iterative process of – define the concept, do background research, specify requirements, brainstorm solutions, choose the best solution, do the development work, build a prototype followed by test and redesign.
  11. Models will be evaluated on dimensions including a) simple, intuitive, easy to understand the underlying concept (b) replicable by children at home and durable for repetitive learning (c) relatable to a real life application (d) complete documentation of the engineering process adopted as per prescribed format (e) communication skills – presentation (f) creativity.



  1. What are waves and what things they can do? – Describe pattern of waves in terms of amplitude and wavelength, and show case waves can cause objects to move.
  2. How can water, ice, wind and vegetation change the land? – Demonstrate effects of weathering or the rate of erosion by water, ice, wind or vegetation. How can we reduce the impact of such processes on humans?
  3. How do internal and external structures support the survival, growth, behavior and reproduction of plants and animals? Develop a model that depicts these structures on which plant and animal life thrive.
  4. Light and what we see:Develop a model where an object can be seen when light reflects from its surface to enter the eye and create an image of the same. How do we see things in varied colors?
  5. Conservation of energy and Energy transfer :What is energy and how is it related to motion? Establish the relationship between the speed of an object and the energy of that object. Demonstrate that energy can be transferred from place to place by sound, light, heat or electric currents or from object to object through collisions. Apply above concepts to design, test and refine adevice that converts energy from one form to another (energy transfer)
  6. Interdependent Relationships in Ecosystems – The food of almost any kind of animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants. Some organisms, such as fungi and bacteria, break down dead organisms (both plants or plants parts and animals) and therefore operate as “decomposers.” Decomposition eventually restores (recycles) some materials back to the soil. Organisms can survive only in environments in which their particular needs are met. A healthy ecosystem is one in which multiple species of different types are each able to meet their needs in a relatively stable web of life. Newly introduced species can damage the balance of an ecosystem. Design a model that captures these concepts.
  7. Cycles of Matter and Energy Transfer in Ecosystems – Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases, and water, from the environment, and release waste matter (gas, liquid, or solid) back into the environment. This system can be described in terms of its components and their interactions through a model.
  8. The Roles of Water in Earth’s Surface Processes – Nearly all of Earth’s available water is in the ocean. Most fresh water is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere. Rest of water on Earth is salty and why? Develop a model that depicts how the Earth’s water and surface process resulted in what is observed.
  9. Inheritance of Traits &Variation of Traits – Different organisms vary in how they look and function because they have different inherited information. The environment also affects the traits that an organism develops. (example of environment influence – tall plants in insufficient water conditions are stunted; pet dogs being fed too much or worked on less become overweight). Sometimes the differences in characteristics between individuals of the same species provide advantages in surviving, finding mates, and reproducing. (Example animals that camouflage or plants with self defense mechanisms (thorns)). Develop a model that depicts the inheritance and variation of traits driven by the environmental challenges species face.
  10. Develop a multi-purpose microscope for students to use in classrooms and homes to study diverse forms of plant, animal and microbes and other matter of interest.


Develop tools that can help explain the following concepts:

  1. Properties of Addition-Subtraction and Multiplication-DivisionE.g., – Commutative property, Associative property.
  2. Factors and Multiples–What they are, how are they different, HCF, LCM; simplifying numbers into factors.
  3. Algebra: Find a rule in number patters and write an equation
  4. Balanced Equations: An equation holds good when both sides of the equation are treated equally by adding/subtracting/multiplying/dividing.
  5. Decimals – Write in Tenths & Hundreds – Eg., convert 42cents into a fraction and decimal; show a fraction in Tenths and Hundredths; comparison and ordering of decimals; decimal operations; fraction and decimal equivalents; ordering decimals, fractions and mixed numbers
  6. Probability – introduce concepts using fractions – favorable outcomes by total possible outcomes; use of Tree Diagrams – mapping possible outcomes and determining chance of desired outcome
  7. Order of operations – PEMDAS ; using order of operations in algebraic equations
