Myth Busters: The Truth is Out There
Appropriate for Students in Grades 3-5
What do I need to do?
- Choose one of the “science myths” that interests you
- Design a creative and accurate demonstration, experiment, or model to “bust” the myth and explain the “real science” to your audience. Remember … you want to change their thinking …. permanently.
- Create a presentation that teaches others the truth about your science myth !
→ This can be on a science fair board OR a digital presentation.
Be Ready for STEM Expo…
- Be an expert - practice your presentation
- Be sure your model, demonstration or experiment is accurate & creative!
- Make sure you share where you got your information!
- Make sure your presentation** is neat and attractive
** Parent help is encouraged!
Physical Science Myths:
- forces always produce observable effects
- the larger the magnet, the greater the force.
- light travels from the eyes to the object
- energy can disappear or be stopped
- gases are not matter
- molecules in a solid do not move
- mass and weight are the same thing
- solids are always heavier than liquids
- all substances melt, freeze, and boil at the same temperatures
- gases have no mass
- the volume of irregular-shaped objects cannot be measured.
- freezing and boiling are examples of new substances forming
- mass determines how quickly gravity pulls an object down
- if an object is not moving, no forces are acting upon it.
Life Science Myths:
- all insects have the same stages in their life cycles
- same species living in different habitats always look and behave the same
- overpopulation of a species can be harmful and change an environment.
- only animals have structures to defend themselves
- plants get their food from the soil
- space is not a basic need of organisms
- only humans are responsible for the destruction of habitats and ecosystems
- predators are always larger than their prey
- stable ecosystems have similar population sizes of predators and prey
Earth and Space Science Myths
- humans lived at the same time as the dinosaur
- organisms are not related to/descendants of extinct organisms.
- fossils are always bones left from dead animals
- weather and climate are the same thing
- waves are caused by Earth’s tides.
- aquatic fossils are only found under oceans
- landforms form quickly and are destroyed quickly
- volcanoes and earthquakes only occur at plate boundaries
- mountain chains do not change as the Earth’s plates move
- natural gas and gasoline are the same thing and come from the same sources
- the sun is the largest star
- all stars are the same size and that stars in a constellation are close to each other
- the sun moves across the sky
- stars and constellations appear in the same place in the sky every night
- the Sun disappears at night and that the Moon disappears during the day
- once water has been used that it is gone forever
- most of the water on Earth is freshwater
