I am trying to plan out my science units for the year. I haven't been very good so far in making science "fun" for certain topics. I need help coming up with fun activities for the following topics: 1. Using a magnifying glass 2. Gravity: Push/pull, pulley/wedge/etc 3. Temperature 4. Scientific process 5. Magnets I have a few good ideas for animals (growing and changing), life cycle, 5 senses, and plants. Other ideas would be welcome though! Any ideas???
