Back to School-Back to Science

Back to Fundamentals with Discovery Science Center

Impacting over 270,000 students per year in Southern California, Discovery Science Center is a cornerstone in the educational community, providing resources for children and teachers alike. Some of the opportunities available through an education partnership with the science center include (1) Interactive field trips to the Center, (2) Science to Go programs and assemblies that are grade-level specific, (3) Free monthly professional development classes for teachers, (4) Free education assemblies with accompanying booklet and/or kits that teach our children how important it is to conserve our resources, and (5) After school instruction aligned with the California Science Content Standards.

In fact, all of Discovery Science Center’s programs align with the California Science Content Standards. So how do you qualify for an education partnership with Discovery Science Center? Just ask. The Center offers a new TEN (Teacher Education Network) membership that awards points to individual teachers who participate in the programs. These points qualify the TEN members to win prizes that will be awarded at the Annual Educators’ Evening of Science event, held at Discovery Science Center on Sept 22, 2010 from 4-7 pm. The TEN Grand Prize at this year’s event is a 3-day, 2-night stay at Hotel Del Coronado in San Diego, along with tickets to the San Diego Zoo, Sea World, and the Ruben H. Fleet Science Center. However, qualifying TEN members must be present to win.

If you are not yet a TEN member, feel free to attend the Annual Educators’ Evening of Science (the event is open to educators, PTA administrators, and school administrators only; no children please). Learn more about what Discovery Science Center has to offer and the Educator’s Evening of Science HERE .

An Apple for the Teacher, Parent, and Child

Some seeds are able to float. How does the ability to float help the seed? (Answer: By maintaining the plant’s population, expanding the range of the plant, and relocating the plant if needed). Some entire fruits which carry the seeds are also capable of floating.

Plan a simple experiment with a few different fruits to see which ones sink and which ones float.

  1. Fill a plastic container or sink half full of water.
  2. Have your child/the students predict whether an orange will sink or float.
  3. Drop the orange in the container (it will float).
  4. Now, peel the orange and test it again (the orange will sink).
  5. Ask: why did the orange float with the peel on? [Answer: An orange’s peel is full of little air pockets and oil that are less dense than water, so the peel helps the orange to float. When the peel is taken off, the orange pulp is denser than water to stay afloat, so it sinks.]
  6. Test an apple, avocado, or other fruit by dropping them in the container of water (no need to peel these). Have your child/the students first predict which might float, then discuss the results with the students.

Make your own Rocket at Home!

Make Your Own Rocket!

Materials:

Towels

Fuji Film Canisters with inverted lids

Seltzer tablets

Water

Cookie Sheet

Discussion

Make your own seltzer tablet rockets which demonstrate the results of a chemical reaction.  If you look at the ingredient list of Alka-seltzer, you will see it is made primarily from baking soda (sodium bicarbonate) and citric acid.  When dealing with acids and bases on the pH scale, you may notice that these two ingredients are the opposite of one another: baking soda is a base and citric acid is, of course, an acid.

When you drop the tablet in water, this enables a chemical reaction (very similar to when you mix baking soda and vinegar to create a model volcano). The dry chemicals are released into the water where they can chemically react with one another.  You can see the tablet start to break apart and fizz.  The fizzing is the production of gas bubbles  ~ the production of gas is evidence of a chemical reaction.  In this experiment, the gas produced is carbon dioxide (CO2).

The carbon dioxide in this reaction helps reduce the amount of stomach acid, relieving acid indigestion and heartburn (which is really esophagus burn since the stomach acid can work its way up into the esophagus).  There is also aspirin in the Alka-seltzer which can help relieve the pain produced by too much acid in the digestive system.

We are going to use this chemical reaction as energy to power our film canister rockets.

Guidelines

Fill  film containers about 1/3 of the way full of water.   On the count of three,  break piece of tablet in half, drop broken tablet pieces into the container, make sure they give the container a quick shake, then place the container lid-side down onto the cookie sheet.  Explain how important it is that the students then sit back and not hover over the cookie sheet ~ the force of the blast-off can do real harm.

What is happening

As the Alka-Seltzer tablet dissolves, it releases carbon dioxide, filling the film canister to the bursting point  ~ increasing the air pressure inside the canister.  The lid pops off as the gas rushes outward; this outward rushing air pushes the film canister upward ~ a great example of Newton’s Third Law:  “For every action, there is an equal and opposite reaction.”

If you imagine yourself swimming in a pool and pushing off of the side to begin your swim ~ you have an idea of how the gas molecules push off of the end of the film canister on their way to rush out of the opening of the canister.  (The amount of force you have to use to push yourself off the side of the pool is equal to the amount of force required to get you a particular distance in the pool ~ your feet are pushing backwards while your body is moving forward in the opposite direction.)

Now think of you as the film canister and the side of the pool as the cookie sheet.  Since the film canister is not heavy, it responds by pushing off of (away from) the gas, thereby moving in the opposite direction of the escaping gas.  So the force hitting the cookie sheet as the gas rushes out is equal to the force that propels the film canister upward: “For every action, there is an equal and opposite reaction.”  (Use your hands starting palm-to-palm and moving away from each other to show equal forces moving in opposite directions.)
