This molecule is responsible for making living things unique.

What is DNA?

100

This is the tiny building block that makes up all living things.

What is a cell?

100

Yogurt, kombucha, sauerkraut, and kefier all contain these microbes.

What are bacteria?

100

This tool helps us see things too small for our eyes alone.

What is a microscope?

100

This type of scientist studies living things.

What is a biologist?

200

We used this to break down strawberry cell membranes to release strawberry DNA.

What is soap, detergent, or extraction solution?

200

The cell structure that holds DNA.

What is the nucleus?

200

Vaccines protect us from these microbes.

What are viruses?

200

This technique allows scientists to view tiny organisms and cells by magnifying them many times.

What is microscopy?

200

Wearing this helps protect us during experiments and helps keep our experiments from becoming contaminated.

What is personal protective equipment (lab coats, gloves, or goggles)?

300

DNA is insoluble in this. We added it to our strawberry experiment so we could see and collect the DNA.

What is alcohol?

300

This part of the cell acts like a gatekeeper, controlling what goes in and out.

What is the cell membrane?

300

These type of cells help us fight off pathogens like bacteria and viruses.

What are immune cells?

300

Cells work together to form these larger biological structures.

What are tissues?

300

Biologists perform these to test hypotheses about the effects of medicines on living things.

What is an experiment or study?

400

These are small sections of DNA that give instructions for specific traits, like curly hair or blue eyes.

What are genes?

400

These structures inside cells perform specific jobs and help the cell stay alive, just like organs in your body.

What are organelles?

400

These substances are used to kill or slow down the growth of bacteria. We used two natural ones, honey and vinegar.

What are antibiotics or antimicrobials?

400

These are groups of tissues that work together to perform a specific function in the body.

What are organs?

400

Mutations in DNA can lead to this.

What is disease?

500

This is the structure of DNA.

What is a double helix? (spiral, twisted ladder, coiled structure)

500

This is the tough protein found in your hair and nails that we made from pipe cleaners.

What is keratin?

500

We used this jelly-like substance to grow bacteria in petri dishes.

What is agar?

500

A microscope does this to help us see things we can't with our naked eye.

What is magnification?

500

In lab experiments, scientists use this group to ensure their results are not due to chance.

What is a control group?
