Genetics Games!

Seventh-graders, here are some games to help you build your understanding of genetics.

Also, here is an extra credit opportunity! Take a quiz to help you practice using Punnett squares. At the end of the quiz, after you see your results, there is an option at the bottom of the page to email the results to your teacher. Enter my email address, elewing@cps.edu, and receive one point of extra credit for every question you get correct. This offer is good through December 4, 2009.

To help you through these activities, remember these vocabulary words:
  • allele: an alternate form that a gene can have for a single trait. For example, the trait of eye color has an allele for blue eyes and an allele for brown eyes.
  • dominant: a trait that is "stronger" than another trait, so that it covers it up, or dominates it
  • recessive: a trait that "hides," so that it may not be visible even if the person carries it in their genes
  • genotype: the genetic blueprint of an organism
  • phenotype: the way an organism's genes are displayed outwardly; the traits you can actually observe
  • heterozygous: having two different alleles for a trait (for example, Tt, Bb, Gg)
  • homozygous: having two of the same alleles for a trait (for example, tt, BB, GG, aa)

Cell Practice

Seventh-graders have a quiz this week on cells, their parts, and the ways they reproduce. If you need a little extra help, check out The Incredible Megacell to read an interactive comic about cells and their organelles, and play a game to see if you know what job each organelle does.

All About Coal

In sixth grade, we have been learning about the energy resources that power our world. Today we are going to investigate coal.

In class, we talked about how coal is formed. Find out more about coal formation by visiting the Energy Kids site on coal.

After you have read about how coal is mined, watch this video to see what a coal mine actually looks like.

But how does using coal impact the environment? Return to the Energy Kids to find out.

On television and in commercials, you may have heard people discussing the idea of "clean coal." Is such a thing possible? Learn more about the "clean coal" debate by watching this news report.

How Do We Make Drinking Water Drinkable?

Since we began our unit on water, the 8th grade has been exploring the chemistry of our favorite liquid. This week, we are learning about how chlorination is used to eliminate harmful substances in our drinking water.

To find out more, this week we will look at the City of Chicago Water Treatment website. Respond to the questions below on the Lab Debrief page of your science notebook.

1) The site tells us that water easily picks up pollutants and dangerous substances because it is a very good solvent. What is a solvent? Go here and write the definition you find. Then write the definition of solute. Draw a picture to help you remember which is which.

2) What is the concentration (in parts-per-million) of chemicals added to our drinking water?

3) Take a look at this Chicago water timeline. What year did engineers reverse the flow of the Chicago River to help keep Lake Michigan clean? What year did chlorination begin? Write your responses in complete sentences.

How Much on Mars?

This week, seventh-graders are learning about the difference between mass and weight. Mass is the actual amount of matter in an object, while weight is a measure of the pull of gravity on that mass. So if you were traveling in space, your mass would be the same-- you would still contain the same amount of matter-- but your weight would change, because the pull of gravity on your body would change.

To find out more, click here and calculate just how much you would weigh on the other planets of our solar system.

And if you want to feel teeny tiny, take a look at this.

What Does an Engineer Do?















Without engineers, that bridge wouldn't hold weight, those boats wouldn't float, and those buildings wouldn't stay up!

This week, sixth-graders worked on designing bridges, building them, and testing them to see how much weight they could hold. Their work combined scientific methods, creativity, and practical problem-solving. It was a nice introduction into a type of science that many people don't think of or appreciate enough-- engineering.

What does an engineer do? Basically, engineers design and build things that make our lives easier and safer. An engineer is an inventor, a mathematician, and an artist rolled into one career. Some people say that engineers are not really scientists, because a scientist's job is to figure out how the world works, while an engineer's job is to create brand new things for the world. However, I would argue that to be a good engineer, you need to think like a scientist, because scientific thought is all about asking questions and solving problems.

You probably don't spend much time thinking about engineering. Maybe you've never even heard the word before. But if you look around you, almost everything in our world was created by an engineer! Look at it this way-- if nature didn't make it, an engineer did. An engineer designed your apartment building to be strong and sturdy even in terrible weather. An engineer designed the desks you use at school, to make sure they are the right height for you. A chemical engineer made the shampoo you used to wash your hair. Check the label of your shirt-- is it made from a man-made fabric like polyester or acrylic? Those were created by chemical engineers, too. The planes in the sky were made by aerospace engineers, the CTA trains were designed by mechanical engineers, and our electricity is able to travel from the power plant into our homes because of systems designed by electrical engineers. The fact that the highway doesn't crumble under our weight when thousands of cars go over it every day can be attributed to civil engineers, who also design things like bridges and roads.

To learn more about engineering, visit the Discover Engineering site. Be sure to click on "What's Engineering?" to learn more about what it's like to be an engineer as a job. The show Design Squad challenges kids to work in teams as engineers to solve challenges, and you can watch an episode or two here. If you want to improve your engineering skills at home, the PBS show ZOOM has some great design activities you can try out. For information that is more detailed but not as kid-friendly, visit the National Engineers Week Foundation.

Peanut is Famous!

Our beloved class pet, Peanut, has something to be proud of this week-- her species, the leopard gecko, is in the news! Well... their tails are, anyway.

When people first meet Peanut, one of the first questions they ask is why her tail is so funny looking. Her tail may be fat, purple, and generally kind of weird, but it serves a purpose! We already knew that the tail can come off and flop around to distract predators, but recent research has brought out new details. Scientists used a high-speed camera to record exactly how the tail moves. If the tail just moved in a simple back-and-forth pattern, predators would understand that it was a trick, and chase after the poor gecko instead of being distracted by the tail. But it turns out that the tail actually has special neurons (nerve cells) to make its movements more complicated and realistic. Amazing!

Why Water?

The 8th grade will be beginning the year with a unit on water, and we'll be studying water for about two months! That seems like a long time to learn about something so simple! But there is more to water than meets the eye. In fact, the quest to solve the world's water problems is one of the biggest challenges of the 21st century.

You probably remember learning about the water cycle. (If not, here is a quick review.) There is never any new water made on Earth; the same water just loops around and is "recycled" over and over again. This means that water is a finite resource, meaning there is a limited amount of it that is available for us to use. So, it is very important that we take care of the water we have!

"But wait, Ms. Ewing," you may be saying. "When I look at a map, it seems like the whole world is covered with water!" You're right, of course. About 70% of our planet is covered with beautiful water. But 97.5% of it is salt water! We can't drink that! So only 2.5% of the Earth's water is even freshwater, and most of that small amount is frozen in the icecaps at the North Pole and the South Pole. And some of it is trapped as moisture in the soil under our feet, so we can't drink that either. At the end of the day, less than 1% of the water on Earth is available for us to drink. No wonder so many places on Earth are threatened because they don't have enough water.

This is a problem, because we all need water to live! When we don't take care of the water we have, people's lives are at risk. In previous centuries, people didn't know what to do to keep water clean, and in Chicago and other cities many people died from cholera and other diseases spread by unclean water. Now, we have the knowledge and the technology, and yet people all over the world are still sick dying because they can't get safe water. One out of five people in the world population lacks clean water, and 80% of diseases in developing nations comes from unsafe water, killing over 25,000 people every day. Children are especially at risk, because their bodies are still growing and can be vulnerable to these diseases. Click here to see how children in other nations are affected by this issue. Of course, in addition to needing water to drink (a lot-- about 16,000 gallons in your lifetime), we also need it to grow our food and produce goods in our factories. The last time you turned on a faucet, did you ever imagine how important that simple, familiar substance is?

Science Fair Ideas...?

Yes, I know... it's summer. Hearing the words "science fair" probably makes your head hurt. But the more time you spend thinking about the science fair in advance, the easier it will be-- and the more fun you will have.

Often, students choose a project they find in a science fair book or on the internet. This may seem like the easy way out at first, but the problem is, it's usually much less interesting-- and sometimes much more difficult and confusing-- than if you had come up with a project yourself. Why copy something you find online when there are interesting science questions all around?

Try this: come up with a list of things you find interesting. These can be things you learn about in school, things you do for fun, things you like to watch on TV-- anything, really. Here's a list of some things that interest me, as an example:

  • animals
  • cooking and food
  • music
  • books
  • basketball
Now, all you have to do is start paying attention. I'm serious. If you look closely, science questions are all around us! If you care about something, don't you want to know how it works? Here are some questions that would make great science fair projects, based on my interests:
  • animals-- Do goldfish remember you, or is it true that they have a 4-second memory?
  • cooking and food-- Does adding salt to water really make it boil faster?
  • music-- Does listening to music make doing homework easier or harder?
  • books-- Do pictures help you remember things from textbooks?
  • basketball-- Which brand of ball bouncest highest? (I had a student do this one!)
Have a topic you want to do, but you need help coming up with a question? Or maybe you think you have a good idea for an experiment, and you want to know what to do next? Ask me for help!

How Much Do Animals Remember?

Another teacher told me recently of how happy her pet fish are when she comes to feed them, and the custodian at our school speaks warmly of our class pet, Peanut the leopard gecko, being excited to see her in the evening. Do animals remember us so richly, or are we anthropomorphizing-- a fancy word for imagining that our furry friends have human traits? Well, for one thing, the popular myth that goldfish have a three-second memory has been busted-- by a kid doing a science fair project, no less!-- but here's an even more inspiring story that you may have heard about:

About Ms. Ewing

I'm proud to be a Chicago native and Chicago Public Schools alum. I received my bachelor's degree from the University of Chicago and my master's degree from Dominican University.

I believe that students learn best when they have the opportunity to examine the world around them, ask questions, solve problems, and appreciate how amazing our planet really is! Instruction in our classroom focuses on inquiry activities; students do hands-on labs and spend time collaborating with one another to describe their observations and draw conclusions. Research shows that inquiry-based curricula lead to a better and longer-lasting understanding of science. Besides that, we all know that doing something yourself is way more fun than just hearing about it in a lecture! My aim is to help every student reach his or her fullest academic potential, to walk away as a responsible and knowledgeable citizen, and to have a whole lot of fun in the process.

I like: teaching, reading all kinds of books, listening to and playing music, traveling everywhere, watching basketball, cooking. And reading science news, watching television shows about science, talking about science, dreaming about science....

I dislike: excuses, complaints, missing homework, and mosquitoes.

Astronauts On Break

I was thinking about the Hubble Space Telescope because it's been in the news a lot lately-- scientists are repairing it for the last time as they get it ready for retirement. I found myself wondering: what do astronauts like to take with them on a space shuttle?

A brief search didn't turn up an answer to my question, but it did lead me to an article about what astronauts do on their day off.

Of course, Alan Shepard famously played golf on the moon (YouTube video here). I think it would be pretty fun to play basketball on the moon....

But back to my original question-- what do astronauts take with them? Playing cards? Comic books? A Nintendo DS? What would you take with you, if you were an astronaut living in a teeny-tiny space shuttle?
