Types of scientists

In the field of science, there are special names for people who study specific topics or things.

There is a different name for almost every type of scientist, and these names are usually based on a special pattern. For example, a geologist is a person who studies rocks and minerals.

Brainstorm

Bug scientist

  • What do you think the name for a person who studies bugs would be?

Record as many possible names as you can think of using a method of your choice.

When you are finished with your brainstorm, press ‘Answer’ to access the name for a person who studies bugs.

A person who studies bugs is called an entomologist.

“Entomo” is a Greek word that means insect, and “logy” is Greek for “the study of”. When you put these two words together, you get the new word “entomology.”

Root words

The special naming pattern for types of scientists uses root words. A root word is a word that can be used to make new words.

In English, root words often come from other, older languages such as Greek or Latin. We can look at the definition of root words from other languages to help us guess what some English words mean.

Explore the following words and root words. For each word, select the root word that it contains.

Pause and Reflect

Science words

Lots of science words end with “ology” or “ologist.”

Can you think of any other words that have “ology” and “ologist” at the end?

Record as many words as you can think of using a method of your choice.

Ontario connection

This learning activity highlights people, places, or innovations that relate directly to the province of Ontario. Enjoy the exploration!

Spongy moths in Ontario

Plants and animals that share habitats rely on each other. This means that a change in the insect population can change the plant population, which has happened in Ontario before.

During the summer of 2021, some places in Ontario were overcome with spongy moths. These insects came from Europe in the late 1960s.

Did You Know?

Scientific names

Every animal has a special name that is used by scientists.

The scientific name for spongy moths is Lymantria Dispar Dispar.

When the spongy moth population becomes too big it can be harmful to forest habitats. If their larvae (or caterpillars) eat too many leaves, trees can become stressed and possibly die. This is called defoliation.

In 2021, spongy moths were harmful to forests in many areas of southern Ontario.

A map showing areas of moderate to severe defoliation caused by the Lymantria Dispar Moth in Southern Ontario. The heaviest concentration of defoliation is north of Lake Ontario as well as between Lake Huron and Lake Ontario.

What does the spongy moth do to forests?

  • caterpillars feed on new leaves and may also eat other plants
  • eating too many leaves puts trees at risk for other pests, drought, and poor growth
  • hardwood trees can keep growing because they produce two times during the season

Invasive species

Spongy moths are one example of an invasive species.

So what exactly is an “invasive species”? Think about the word “invade” and what it means. Now make a guess about what you think an invasive species is.

Press ‘Answer’ to access the definition of invasive species.

An invasive species is any living thing that is not native to an area. This means that they are not originally from the area.

Invasive species disturb ecosystems. They can cause harm to other plants and animals that are native to an area.

Exploring invasive species in Canada

We are now going to explore invasive species that have come to Canada.

Press the following tabs to access descriptions and videos of some invasive species in Canada.

Rusty crayfish were originally used by fishers for bait. They were released into lakes and rivers beginning in the Kawartha Lakes region in the 1960s.

Sea lampreys are eel-like fish that invaded the Great Lakes region in the early 1900s when a shipping canal was created.

Zebra mussels are freshwater mussels that traveled to Canada from eastern Europe and western Asia in the 1980s. They are very adaptable and can survive in many different water conditions.

Asian carp is a general name for several invasive species of fish in Canada that all belong to the carp family. These fish are native to areas such as China and Russia and entered Canada in the 1960s and 1970s.

Consolidation

Protecting water habitats

In this learning activity we have explored types of scientists, invasive species in Canada, and how invasive species harm habitats.

Think about what you have learned about invasive species and how they harm water habitats in Canada.

Now share what you have learned by creating a poster or by recording a presentation using a method of your choice. Include answers to the following questions:

  • What is an invasive species?
  • How are invasive species harming water habitats in Canada?
  • How are scientists helping to address invasive species?
  • What is one example of an invasive species in Canada?

Use the following checklist to help you make your poster or presentation.
