Free short notes and revision cards
Grade 5 Environmental Science on Temari has 15 revision cards, arranged by the chapters of the Ethiopian national curriculum. Every card says when the rule applies, what each symbol in it stands for, and the mistake students most often make with it. They are free to read and need no account.

When you use it
Use when distinguishing between coordinate-based locations and boundary-based locations on maps.
Watch out
Never use neighboring landforms or countries to describe absolute location. Absolute location requires numerical degrees of latitude and longitude, whereas relative location uses surrounding bodies of land or water.

When you use it
Use this distinction whenever explaining the difference between the amount of matter in a body and the force acting on it.
Watch out
Mass is the amount of matter in an object measured with a balance in kilograms, while weight is the gravitational pulling force of the Earth.

When you use it
Use this rule when determining how sound travels through different states of matter or in empty space.
Watch out
Sound cannot travel through a vacuum because it requires vibrating particles. It travels fastest in solids and slowest in gases.

When you use it
Use this formula to calculate the space occupied by a regular rectangular solid given its three dimensions.
Watch out
Ensure length, width, and height are in the same unit before multiplying.

When you use it
Use this formula to calculate the average temperature of a given location for a single day.
Watch out
Add the maximum and minimum temperatures first before dividing the sum by 2.

| Soil Type | Particle Size | Water Retention | Plant Growth |
|---|---|---|---|
| Sandy soil | Large particles | Low (drains rapidly) | Not suitable |
| Clay soil | Very small particles | Very high | Not suitable (poor air supply) |
| Loam soil | Mixture of small and large | Balanced | Suitable (best for growth) |
When you use it
Use this to compare soil particle sizes, water retention capacity, and suitability for plant growth.

When you use it
Use this when distinguishing short term atmospheric changes from long term regional patterns.
Watch out
Weather changes within 24 hours, whereas climate is an average pattern recorded over at least 30 years.

| Heritage Category | UNESCO Registered Examples in Ethiopia |
|---|---|
| Tangible Heritage | Axum Obelisk, Lalibela Rock-Hewn Churches, Gondar Castles, Harar Jugol, Tiya Stones, Konso Landscape, Lower Awash, Lower Omo, Simien Mountains |
| Intangible Heritage | Meskel Festival, Timket Festival, Fichee-Chambalaalla, Gada System, Irreecha |
When you use it
Use this reference to distinguish between physical tangible heritages and living intangible traditions.
Watch out
Tangible heritage includes physical objects and structures, whereas festivals, rituals, and the Gada system are intangible.

When you use it
Use this card to classify Ethiopian industrial activities by their scale, inputs, and complexity.
Watch out
Food processing and textiles belong to light industry, while cement and steel manufacturing belong to heavy industry.

An exam paper keeps asking for what the year below taught. Those cards are here too.
Everything else in this year that has cards so far.
Temari turns these cards into practice questions and marks them as you go, with an AI tutor to explain anything that did not land.
