Here are a few of the Spider Bots that the students have been creating. We worked on this project with our other 5th grade Lighthouse teammates. It was great to see everyone fully engaged in engineering practices such as designing, identifying problems, coming up with solutions, and redesigning. I was very impressed with all the creativity, problem solving and cooperating going on during this fun activity!

During the last two weeks of our science unit on cells we learned about osmosis. We did this using eggs. We soaked our eggs in vinegar overnight in order to dissolve the shells. The eggs then had only a thin membrane holding them together. They were rubbery and translucent and lots of fun to hold! In order to see osmosis in action, we observed what happened to the shell-free eggs when they were placed in substances like molasses, light corn syrup, and dark corn syrup. We discovered that the eggs lost water and shriveled up. We learned that this is because water passes through the membrane from an area of higher water concentration (egg) to an area of lower water concentration (molasses and corn syrup) in a process called osmosis. We then placed the shriveled eggs in water with food coloring. Ask your child what happened. It was very cool! Check out the pictures below.

We began our science unit on cells a few weeks ago. In one activity, students carefully removed thin sheets from an onion, created their own slides, and viewed them under microscopes. The cells of the onion were visible and students sketched their observations.
We have also been reading about cells and using a website called Cells Alive! to learn more about cells.
We did a school and cell analogy activity where we compared the school to a cell. For example, the nucleus could be compared to the main office, and the cell wall to the outer brick wall. Ask your child what the endoplasmic reticulum or the vacuole would be analogous to! This week we are beginning a very cool hands on activity with eggs to learn about osmosis. Stay tuned!

This Friday students will take the Unit 1 summative math assessment. The test will cover the topics listed below. The students have been working hard since the beginning of the year and are ready to show all they've learned!
1. Evaluate expressions with grouping symbols.
2. Write expressions to model situations.
3. Find the area of a rectangle with one fractional side length.J1
4. Identify objects with volume.J1
5. Use cubes to find volume.1
6. Use formulas to find volume.1
7. Find the volume of a figure made of rectangular prisms.
