Biology – A Tour of the Cell

(www.nsf.gov/news/overviews/biology/interactive.jsp)

Age Range: 11-18 (Grades 6-12, with parental supervision)

 

Can you imagine how many millions of these tiny cells are inside of your body at this very moment? Amazing! This tour of a cell from the National Science Foundation is very detailed and informative.

“Although the cell is the smallest unit of life, it is by no means simple.”

Thus begins this brief-but-fascinating exploration. The opening picture is a large, full-color image of a cell. To begin, click on any of the numbered parts of the cell and a beautiful, detailed close-up image of that cell art will appear, along with one or two paragraphs of information about it. Parts featured include: 

  • the cell membrane
  • DNA
  • RNA
  • endoplasmic reticulum
  • mitochondria

and more.

Once you have viewed a part of the cell, you will see small numbers below the photo of that part. These numbers provide a convenient way to navigate through the site sequentially, if you prefer. If you click “Explore More,” you will go back to the main page.

CSI: Forensic Science Interactive Games

(forensics.rice.edu/)

Age Range: 11 and up (Grades 5 through adult; children with parental supervision)

 

This website from Rice University in conjunction with CBS, the National Science Foundation and the American Academy of Forensic Sciences, and others, offers free interactive forensic science investigations based on the CSI television series.

You become a CSI investigator, analyze the forensic evidence, and test your investigative and problem-solving skills to crack the case! If you aren’t familiar with CSI (Crime Scene Investigation), you should know that the object of each activity is to investigate a crime scene that involves a death and/or homicide. Parents, AS ALWAYS, should preview the site to determine suitability of content.

When you get to the site, find five CSI cases:

  • Case One: Rookie Training (Beginner Level) – Visit online labs to collect information and tools about forensic biology, toxicology, firearms and toolmarks, the medical examiner, and CSI ethics.
  • Case Two: Canine Caper (Intermediate Level) – Interview suspects, visit the crime scene and labs, take photographs and measurements, collect and analyze evidence and data.
  • Case Three: Burning Star (Advanced level)
  • Case Four: Bitter Pill (Advanced level)
  • Case Five: Fatal Interactions (Advanced level)

The last three cases are more complicated and require some time to collect evidence and analyze it using a variety of tools and resources. Challenging, fascinating and informative! If you have any difficulty with navigation, click on “WalkThrough” in the upper right corner of the screen for each individual case, to get directions on how to proceed.

You are given the opportunity to register (free). It allows you to save your place so that you can continue wherever you left off after a session. One game can take more than an hour to master.

Once you’ve explored the “Web Adventures,” use the horizontal menu again and click on “For Educators” to access: 

  • Educator’s Guide – Get free, downloadable activities “to see how bone length can be used to calculate height, create your own bill for forensic testing, or solve forensic logic problems – and more!”
  • Family Guide – The description on the website says, “Looking for some fun forensic activities to do at home? From blood spatter analysis to DNA extractions, we’ve got fun (yet safe) activities for all ages. Check it out!”
  • Online Activities – Learn about entomology, handwriting analysis, and test your memory and power of observation.
  • Cool Links – Get links to websites on forensic science, toxicology, pathology, fingerprints, and other forensic games.

This site requires a lot of time to fully explore, so bookmark it to return.
