Please check out this website. It has tremendous helps. Fractions can be difficult. This site has a review of skills and lets you practice as well.

Friction Experiment
Welcome to Spring Break! Below is a link to site that has a great activity on friction. If you are in need of an idea, you can simply print off and do the activity on the site as your experiment. I would, however, encourage you to use your creativity and interests to design your own experiment.

Have fun experimenting!
The Assignment:
Your assignment is to conduct an experiment related to friction. Scientists start with a question, form a hypothesis, and then share their background knowledge. Next, they tell what they are doing for an experiment that tests their hypothesis. Then the experiment is conducted and observations are noted in the form of words and pictures. Finally, a scientist will determine whether their hypothesis was right based on their observations. This is called analyzing the results. Below is an example of an experiment we did in class with the necessary steps
Example:
1. Question – Will a matchbox car roll better on a smooth surface or a rough surface?
2. Hypothesis – (statement of what you think will happen). A matchbox car will roll best on a smooth surface because there will be less friction.
3. Background Knowledge – My remote control car runs better on the sidewalk than on the grass. Sometimes it gets stuck in the grass. Also, when I roll a basketball on the court it goes far with a little toss. When I roll a soccer ball on the grass it stops quickly unless I toss it really hard.
4. Procedures – (What is the experiment that you are planning to do?)
a. I will place a towel over half a piece of cardboard. One side will be smooth, one side will be rough.
b. I will take two cars and place one on the smooth side and one on the rough (towel) side.
c. I will use a meter stick across the starting line to hold both cars in place. When I lift the meter stick it will release both cars at the same time.
d. I will observe which car makes is faster down the ramp to determine if my hypothesis is correct.
5. Observations and Data – Include labeled pictures, graph, list of what you saw, etc.
a. In math we have been studying fractions, percent and decimals. Can you use fractions, percents and decimals as a way to talk about and share your data?
6. Analyze the Results - My hypothesis was correct. Objects move faster on smooth surfaces. The car on the smooth surface always made it across the finish line first.
Have fun with this. With parent permission, you may look ideas up on the internet. Bring in your project on Monday, March 28th.
