Science Project Updates
Week of March 25, 2019
Finish up your display board. Then please turn it in, with your science project log, on Wednesday, March 27 to be graded.
Week of March 18, 2019
Finish up your science experiments, observations, data collections and write ups (data analysis/results and conclusion). Begin working on your presentation board. The finished project is due to Mrs. Cooke on Wednesday, March 27th. See this link for examples of completed presentation boards.:
Week of March 11, 2019
Finish your experiment "trials" and data collection. Make sure to include notes and data in your Science Project Log. Write about these last four parts of your project.:
- Notes on Experiment - What did you observe each time you checked your experiment? How often did you check it?
- Data Analysis and Results - What were the results of your experiment? Was your hypothesis correct? Did you have any trouble and need to start over? Did you have to change anything from your original plan? You may include charts, tables and/or graphs here.
- Conclusion - What did you learn from your experiment? Was your original question answered? How so?
- Bibliography - List any research you used, where it came from and who the author was (internet articles, books, magazines, etc.)
Week of March 4, 2019
Begin your experiment, at home. As you conduct your experiment, take notes of "trial" results or observations (collect data). You may want to do this on separate paper and then put the most important data in your log. If your experiment is going to last several days, you may want to check it once or twice daily. Make sure to check it around the same time each day.
Week of February 25, 2019
Variables: This week, you will need to list your variables. For the Controlled variable everything you are testing will be the same. This is, also, the case with the Independent variable, but one thing will be different. The Dependent Variable explains what you are measuring with your experiment. See the example below. :
Controlled: (example)
We will use all of the SAME SHAPE and SAME COLOR of marshmallow Peeps. We will use the SAME amount of liquid in each cup and also use the SAME type of cup for each liquid.
Independent:
We will use five DIFFERENT liquids to see which one dissolves the Peeps the most.
Dependent:
After keeping the same size, shape and color of Peeps in five different liquids for five days, we will look to see which one has dissolved the most (gotten smallest).
Week of February 18, 2019
Begin your experiment, at home, and complete the Materials and Procedure sections in the Science Project log. See below for an example. As you conduct your experiment, take notes of "trial" results or observations (collect data). You may want to do this on separate paper and then put the most important data in your log. If your experiment is going to last several days, you may want to check it once or twice daily. Make sure to check it around the same time each day.
Materials: (List every item that will be used. Be specific with amounts, colors, types, etc.)
(example:)
- 5 transparent or translucent plastic cups
- 5 marshmallow PEEPS (rabbits or chicks - whichever fits in the cups the best)
- 1/2 can cola (room temperature)
- 1/2 cup white distilled vinegar (room temperature)
- 1/2 cup sugar water (room temperature)
- 1/2 cup salt water (room temperature)
- 1/2 cup baking soda water (room temperature)
- spoon
Procedure:
1. Gather all materials.
2. Dissolve two teaspoons sugar into 1/2 cup of water (stir). Dissolve two teaspoons salt into 1/2 cup of water (stir).
3. Poor 1/2 cup of each of the five liquids into its own cup.
4. Place one PEEP into each cup and cover with liquid.
5. Observe changes each morning and evening for five days. Record observations each day (collect data).
6. After five days, compare the PEEPs to see which one has dissolved the most.
7. Decide whether or not your hypothesis was correct.
Week of February 11, 2019
We will review the Scientific Method, in class, and talk about how to write a project question, purpose and hypothesis. This week, please help your child write the question, purpose and hypothesis for the project you chose. These will be checked on Tuesday, February 19th. Please see below for an example.:
Question:
- Which liquid will dissolve a marshmallow peep the most over a period of five days-- water and baking soda, vinegar, cola, salt water, or sugar water?
Purpose:
- The purpose of this experiment is to find out which liquid will dissolve the marshmallow peeps the most over a period of five days.
Hypothesis:
- I think the cola will dissolve a marshmallow peep the most in five days, because cola is full of acid.
Week of February 4, 2019
This week, please decide on a topic for your project. I will ask for each student's topic next week. These will need to be approved. Science Project Logs will go home later this week. Please keep these logs in your book bag at all times. They will be checked every week. I will write comments to help guide students in completing their projects.
