Now You See It, Now You Don't: A Chromatic Adaptation Project

Science Fair Project Idea

Scientific Method

This project shows that our perceptions can change, even with the stimulus remains the same. A clear color difference in an image disappears after just 20 seconds of looking at another (special) image. Now you see it, now you don't! Read more

What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of… Read more

NGSS Performance Expectations:

5-LS1-1. Support an argument that plants get the materials they need for growth chiefly from air and water.

Racial and Gender Bias in AI-Generated Images

Science Fair Project Idea

Scientific Method

If someone asks you to draw a picture of a doctor, lawyer, or engineer, what first pops into your mind? The race and gender of the person you imagine might be shaped by your personal life experiences, such as whether you have family members in those professions, or what representations of them you have seen on TV or online. What do you think will happen if you ask an artificial intelligence (AI) program to generate the picture instead? Will pictures generated by AI reflect the true real-world… Read more

Radiant Radish Seeds

Science Fair Project Idea

Scientific Method

We all know that plants need sunlight and water to grow big and tall. But did you know that inside seeds are baby plants, and that the fragile baby plant inside the seed needs to be protected? If you've ever had a sunburn, you also know that the sun gives off harmful radiation and heat. How much radiation and heat can a seed handle? Find out using some radish seeds, an oven, and your microwave! Read more

Rise to the Occasion: Investigating Requirements for Yeast Fermentation

Science Fair Project Idea

Scientific Method

Did you ever wonder how yeast makes bread dough rise? This project will show you what yeast does to make this happen. You'll also investigate the conditions yeast needs to grow. Read more

This lesson will introduce students to the scientific method using a fun, hands-on activity about the role of animal camouflage in evolution. During the activity, students will practice each step of the scientific method including doing background research, making a hypothesis, conducting an experiment, analyzing data, and drawing conclusions. By going through this process, students will also learn how camouflage helps animals survive. Read more

NGSS Performance Expectations:

3-LS4-2. Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.
3-LS4-3. Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.
MS-LS4-4. Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals' probability of surviving and reproducing in a specific environment.
MS-LS4-6. Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.

Have you ever considered taking a nighttime nature walk? Would you wait until there is a full moon, so you could profit from sunlight reflected on the moon, or would you rather take a flashlight? Do you think trees would look black, green, or grey in the dark? Do this activity to examine your night vision and prepare for your next nighttime adventure! Read more
