What a Coral Reef Is

A coral reef looks like rock and is built by animals. A coral polyp is a soft creature the size of a pinhead. It draws calcium from the sea water and builds a hard cup around itself. Millions of polyps, cup upon cup, become a reef. Inside each polyp live tiny algae. The algae make food from sunlight and pass most of it to the polyp. In exchange they get shelter and the polyp's waste. Neither could build a reef alone. When the water gets too warm, the polyps expel the algae. Without them the coral turns white and starves. That is what bleaching means. A reef takes centuries to build and can bleach in a single hot summer.

Lichen

A lichen is not one organism. It is a fungus and an alga living as one body. The fungus provides the structure and holds water. The alga photosynthesises and makes sugar. Separated, the fungus starves and the alga dries out. Because it needs no soil, a lichen can grow on bare rock, on gravestones and on the roofs of cars that have not moved for a decade. Lichens grow extremely slowly — some crustose species less than a millimetre a year. Scientists use that rate to date rock surfaces, a method called lichenometry. Lichens also absorb whatever is in the air. Where the air is dirty, they disappear, which makes them a living measure of pollution.

Questions about Charts, Diagrams and Timelines

What does the Charts, Diagrams and Timelines worksheet cover?

It practises explaining what a visual adds to a text — 2 questions for Grade 4, all on Common Core RI.4.7: Read charts, diagrams and time lines, and say what they add to the text. The instruction to pupils is “Read the text, then answer the questions”, and the answer key follows on the next sheet.

Which Common Core standard does Charts, Diagrams and Timelines practise?

CCSS.ELA-LITERACY.RI.4.7 — RI.4.7, in the Reading: Informational Text domain for Grade 4. The published standard reads: “Interpret information presented visually, orally, or quantitatively (e.g., in charts, graphs, diagrams, time lines, animations, or interactive elements on Web pages) and explain how the information contributes to an understanding of the text in which it appears.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Charts, Diagrams and Timelines is written for Grade 4, typically ages 9-10. It is one of the sheets on RI.4.7, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.

Does Charts, Diagrams and Timelines come with an answer key?

Yes. All 2 answers are generated from the same problems as the questions, so the key cannot drift out of step with the sheet. It starts on a fresh sheet of paper, after the questions, so it is not handed out with the class by accident.

How many different versions of Charts, Diagrams and Timelines can I print?

25 versions, of which 21 ask genuinely different questions — this skill does not have 25 distinct questions to give, so the rest reorder them and no two pupils still share a paper. Set 1 downloads all 25 as one PDF.

Is Charts, Diagrams and Timelines free to print and photocopy?

Yes. Charts, Diagrams and Timelines, its answer key and its 25 versions are free to print and photocopy for your own class, with no account, no email capture and no subscription at the download step. Please do not resell them or republish them as your own.
