does any1 have a good science project idea 4 a 6th grader?

Answer 1

We have found that if you submerse an egg in vinegar, that the calcium will be "eaten" away, leaving a rubber like "egg" behind. The problem is (as a Mom), how do we make this an interesting science project? Would the hypothesis have to do with acidity?
Should they try other substances and if yes, what would be good ones for me to have on hand?

I don't want to sound like I am doing this for my twin 8 year olds, and I expect them to carry out all of the experiments and develope their own theories, but the school has indicated that they could receive some outside help. Where could my kids find the necessary information to do a good job?


We hypothesize that the acid in vinegar will eat away the eggs calcified shell, leaving rubber like remains.

I'd try other substances. Any other liquid should do - milk, water, orange juice, something else really acidic.

But remember, theyre just 8 (1st grade??) I HIGHLY doubt very much is expected. A simple demonstration would probably do fine - at least it would have when I was in 1st grade, maybe its different there =)

Answer 2

I like the idea of doing a science project about something that is topical - maybe a project about pollution or global warming?

I remember doing a project where I bought 4 inexpensive plants from Home Depot, and then watering each one with a different solution.

Maybe you could test the affects of rock salt (the kind that you use to de-ice your driveway) on plant growth.

Make (4) different solutions - a control of plain tap water, and then the rest should be solutions of varying levels of rock salt. You may have to heat or boil the water to get the salt to dissolve in the solutions with a larger amount of salt.

Make sure the plants are kept at the same temperature/amount of light. Water the plants an equal amount of their respective solutions over the period of a month. Have your 6th grader monitor and record the affects. (You could measure height/amount of leaves/etc)

Then help tie the project into a real-life situation like a study on the effects of pollution on a water-shed.

Hope this helps!

Would soil type affect a dinosaur's footprint?

Problem

Would the amount of water and the type of soil affect a dinosaur's footprint?

Materials

1/2 cup (125 ml) flour
1/2 cup (125 ml) cornmeal
Large mixing bowl
Spoon
1/2 cup (125 ml) water
Paper plates
8 inch (20 cm) square baking pan with about 1/2 inch (1.3 cm) of water in it


Most of these items are in your own kitchen. Be sure to ask Mom or Dad if it's okay to use these things. You can buy flour and cornmeal in the grocery store. They are in the section where you find cake mixes.

Procedure

Pour 1/2 cup(125 g) of flour and 1/2 cup (125 g) of cornmeal into the bowl. Mix with the spoon.
Slowly add 1/2 cup (125 g) of water to the cup of cornmeal and flour and mix until it looks like mud.
Pour the "mud" onto a paper plate. Use the spoon to spread it evenly over the whole plate.
Wet your hand in the baking pan.
Spread your fingers. Press your hand into the "mud". Press hard to make a good print.
Remove your hand.
Put the plate in a safe place for 2 days or more. Let the "mud" dry. This might take as long as 5 days, if the air is humid.
Repeat this experiment using different amounts of water, flour and cornmeal. You want to find out if you get a clearer print using different combinations.
Data

In this experiment, the student tried four different mixtures. Her results were different for each one. For example, Mixture B had the most water. It made the worst print. Mixture D had the most cornmeal. It made the best print.

Conclusion

The soft "mud" moved when a hand was pressed into it. The same thing must have happened when dinosaurs walked in soft mud.
Drying out the "mud" created a hard print. Dinosaur tracks are usually found in rocks. Probably muddy tracks dried out so much, they turned into rocks.
Dinosaurs might have walked in places with very wet soil. We will never know. If the soil is too wet, the tracks would have disappeared before they could get dry and hard.

Display Materials

Elmer's® Project Display Board
Elmer's® Science Project Titles
Regular computer paper. Use big type and set the page format to "landscape." You could also print by hand.
Photocopies of dinosaur pictures from a book
The person who created this display decided to make her project board more fun. She put some dinosaur models in front of the display and also added a magnifying glass.

Answer 4

If you still have any of the baby teeth, soak one in Gatorade, one in Lemonade, and one in Coke for a couple of days to show the detrimental effects each has on dental hygiene. Take before and after pictures. You'll never drink those beverages again.
