Compost Creativity: Try Various Methods and Test Soil Fertility

Science Fair Project Idea

Scientific Method

Make your own fertile soil using kitchen scraps, manure, leaves, grass clippings, and other compostable materials. Which materials make the best compost? How does the amount of nitrogen change the rate at which the compost forms? How does a 'hot' compost pile compare to a 'cold' compost pile, or how does traditional composting compare to worm composting, or vermiculture? Figure 1. Different composting methods yield different soils. In this picture, the soil on… Read more

Have you ever thought about the sheer number of words that exist in the English language to describe sounds? A noise can be a thud, a clang, a bang, a pop, a crash, a splash, a clatter, a buzz, a tinkle, and many more! You can probably think of an example for each of these—but if you heard the sound, could you say what produced it? Read more

Students will enter this lesson knowing that materials get warm in the sun. In this fun follow-up activity, your students will get creative with craft materials. They will figure out how to protect an "animal" and its territory from getting too hot in the sun. What will they build to keep their animals cool? This lesson connects effortlessly with the How Sunlight Warms the Earth lesson. Read more

NGSS Performance Expectations:

K-PS3-2. Use tools and materials to design and build a structure that will reduce the warming effect of sunlight on an area.

Cricket Wicket Knockdown Challenge for Grades 3-5

Lesson Plan Grade: 3rd-5th

Teach your students about the engineering design process with this fun lesson plan. They will design and build a ball-launching machine to knock down a target. Optionally, they can enter their designs in the 2020 Engineering Challenge for a chance to win a cash prize for your school! Teachers, note that middle school and high school versions of this lesson plan are also available. Read more

NGSS Performance Expectations:

3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
3-PS2-1. Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.

Cricket Wicket Knockdown Challenge for Grades 6-8

Lesson Plan Grade: 6th-8th

Teach your students about the engineering design process with this fun lesson plan. They will design and build a ball-launching machine to knock down a target. Optionally, they can enter their designs in the 2020 Engineering Challenge for a chance to win a cash prize for your school! Teachers, note that elementary school and high school versions of this lesson plan are also available. Read more

NGSS Performance Expectations:

MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.

Do you enjoy watching mysteries or crime investigation shows? Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what a forensic expert does. In this bloody, Halloween-themed science activity you’ll be correlating the size of blood stains to the distance they fell, but don’t get too grossed out; you’ll be doing it with fake blood. If you like figuring out mysteries, this… Read more

Do you like gift wrapping? If you do, you have probably curled a ribbon with scissors before. Have you ever wondered why the ribbon curls when you run a scissor blade down one side of it? The answer is that when you apply pressure on the ribbon with the blade, the outer layer of the ribbon stretches and expands. This makes the outside layer of the ribbon longer than the inside layer that is pressed against the blade. As a result, the ribbon starts to curl to make up for the different lengths of… Read more

Have you or your students ever felt frustrated at not being able to access a favorite website or online game? Did you realize the site might have been a victim of a cyber-attack? If you aren't careful about online security, your own computer could even be used to launch the attack! In this fun lesson plan, you and your students will model one type of attack (a denial-of-service attack) and figure out how to protect the network against it (no computer programming required)! Read more

NGSS Performance Expectations:

MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
