Students will observe and perform experiments with the elements sodium, potassium, calcium, magnesium, sulfur and phosphorus. Conclusions will be made about trends down groups, across periods and relating to acidity/basicity of metal oxides vs. nonmetal oxides

This intereactive Flash applet helps children learn grouping, tally marks, place value, addition, and subtraction. Students help the alien spaceship move cows into corrals by counting by 5s and 10s. They also can apply those grouping skills to practice adding and subtracting two-digit numbers with regrouping. Audio cues and prompts reinforce the user's actions and facilitate counting and the development of math language.

This task adds some rigor to the activity of growing bean plants. By collecting growth data, students practice measuring and recording length measurements.

This task is designed to make students think about the meaning of the quantities presented in the context and choose which ones are appropriate for the two different constraints presented. In particular, note that the purpose of the task is to have students generate the constraint equations for each part (though the problem statements avoid using this particular terminology), and not to have students solve said equations.

This activity is a classroom lab where students will conduct a controlled activity resulting in the growth of salt crystals, showing a dramatic physical change.

This activity is an indoor lab investigation where students compare and contrast different growing environments for a lima bean seed and discover the optimal conditions needed for growth.

Instructions from the Father of Fast Plants (written by Dr. Paul Williams) about growing Rapid-cycling Brassica rapa (RBR) sucessfully in a Four Cell System (4CS). This file is one of the mini-booklets from "Paul's Sandbox"--it is made Xerox-ready, containing two sheets that together make four copies of two mini information booklets(each booklet measures 8x12cm).The two pages describe the construction, resourcing of materials, and usage of the 4CS, an alternative growing system to the Film Can System described in the Small Booklet titled "Growing Rapid Cycling Brassica rapa sucessfully, Film Can Growing System (FCS)."

Students visit second- and fourth-grade classes to measure the heights of older students using large building blocks as a non-standard unit of measure. They also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form bar graphs) enabling a comparison of the heights of different age groups. The activities that comprise this activity help students develop the concepts and vocabulary to describe, in a non-ambiguous way, how heights change as children age. This introduction to graphing provides an important foundation for creating and interpreting graphs in future years.

This document provides extensive background information about how Fast Plants grow and develop. The distinction between growth and development is explained. Also discussed is how genetics plus interactions with the environment produce variation during growth and development.

A 32-page booklet, containing complete instructions for activities at each life cycle stage. The booklet also includes important background information about plant physiology and how to grow Fast Plants.A Growth, Development and Reproduction kit is available. You can also conduct all the investigations explained in the booklet using seeds from a packet of Standard Wisconsin Fast Plants seeds (or seeds from Fast Plants you grow yourself) and your own potting mix and growing system.Either way, you'll need to plan for providing adequate light. Learn about all these factors in the How to Grow files on this website.

This problem asks the students to represent a sequence of operations using an expression and then to write and solve simple equations. The problem is posed as a game and allows the students to visualize mathematical operations. It would make sense to actually play a similar game in pairs first and then ask the students to record the operations to figure out each other's numbers.

This marbel counting iteration of greater than, less than, and equal to with a specific "target number" help strengthen the concept for students.

This activity is a teacher-directed investigation where students observe leeches, create questions and determine which ones are investigable. Together, teacher and students design and carry out a test for their question and record the information in a science notebook.

Students use gumdrops and toothpicks to make lithium atom models. Using these models, they investigate the makeup of atoms, including their relative size. Students are then asked to form molecules out of atoms, much in the same way they constructed atoms out of the particles that atoms are made of. Students also practice adding and subtracting electrons from an atom and determining the overall charges on atoms.

This role playing game allows students to explore the issue of habitat loss and its effects on animal populations.

This lesson is an introduction to a unit on habitat. It is designed to combine literature and science.

This problem could be used as an introductory lesson to introduce group comparisons and to engage students in a question they may find amusing and interesting. More generally, the idea of the lesson could be used as a template for a project where students develop a questionnaire, sample students at their school and report on their findings.

This Powerpoint presentation contains copies from the Father of Fast Plants, Dr. Paul Williams' research notebook and photos documenting some of his investigations into the inheritance of hairs on the leaves and stems of Fast Plants.

This task involves fraction multiplication that can be solved with pictures or number lines.

In this activity students measure their hand span. A line graph is used to record the data from the glass.
