Animate your Science Ideas

Sometimes students learn by drawing, or, they focus that way. There notebooks are full of sketches. Channeling that artistic energy and simultaneously teaching something new in both art and science can be done through animation.

Students (and teacher/mentors) can pick a science standard from what you are learning during the year, and, then animate a film about it. There are some websites about animation to give you an idea of how animation is done. But, you can do animation with a flip book if you don't have computer access for everyone. Clay has also been used, as presented in "Botany Beat," linked here.


A website for animation concepts using stick figures is:





Some reference information can be found at: http://science.nhmccd.edu/biol/bio1int.htm

ATP


Photosynthesis







Amino Acids




Cell Surface Receptors







DNA and Chromosomes






Gene expression for Deacetylation




Metaphase Histones (DNA Proteins)


A website for adults who want an idea of what is possible with computer animation (but, check it out first, parents may not want this for all ages of children. It is a showcase of animation from Algonquin College): http://www.youtube.com/watch?v=7X8wHCWUy9g

Another website, an advertisement for a school, also requiring parent or guardian checking, can be found by googling: Very Cool 3D Medical Animation. Some medical images are not suitable for all ages, however, this video can point to a career for some.

Happy animating!

Plants have Mitochondria

Why is the headline, "Plants have Mitochondria?" Because, so often students remember that plants do photosynthesis but they forget that plants also do cellular respiration.

Review the basic biology of cells. Think about eukaryotes and prokaryotes. Think about your cells. What kinds of cells do you have? Think about kingdoms of organisms? What types of cells does each kingdom have?

Review the organelles in plant, animal, fungal, protistal, and, bacterial cells.

Scientists meet...

When scientists meet, many ideas are exchanged. People get excited and bring home new research ideas.

You can hold a small scientific meeting with your friends. Get together and present the research you have done since you last met. Have 10 minute formal presentations. Then, take a break, have a snack, and discuss the research. See if you get new ideas for more experiments.

Write an experimental design and submit it to your parents or other supervisors and see if you can do your experiment or another similar one. Remember, those in charge have many things to think about: the budget, time constraints, safety, among others, so, you might not be able to do your experiment, however, designing the experiment itself is fun. Try it.

What do you think about organic farming? Can it save energy and water? Here are some videos on this topic. Make up your own mind about what you think. Remember to evaluate if there is bias in any information you read or see on this topic, including these videos. Checking for bias is an important higher order thinking skill.
